Run Linux On Mac Virtual Machine 2019

A Virtual Machine(VM) is a compute resourcethat uses software instead of a physical computerto runprograms and deployapps. One or more virtual “guest” machinesrun on aphysical “host” machine.Each virtual machine runs its own operating systemand functions separately from the other VMs,even when they are all running on the same host. This means that, for example,a virtual MacOS virtual machine can run on a physical PC.

Sosumi is a snap package based on macOS-Simple-KVM that makes it easy to download and install macOS in a virtual machine (is comes bundled with qemu-virgil, which includes virtio-vga, a paravirtual 3D graphics driver). The virtual machine can then run alongside your normal Mac apps, such as Apple Mail and Safari, allowing you to run Windows and Mac apps on the Mac desktop at the same time. Yevgen is using the UTM app to run virtual machines on iOS devices, then has employed a process to create a virtual Hackintosh with a method shared on GitHub called OSX-KVM. KVM is an open source. Whether you want to try out macOS, run Xcode or make a hackintosh you can use a virtual machine to get started on macOS. Remember the performance of macOS, particularly graphical support is very limited on a virtual machine so performance with graphical animations will be subpar compared to a real mac or hackintosh, but it will still get the job done. A virtual machine (VM) is an operating system (OS) or an application that enables you to run multiple operating systems on the same physical hardware machine, and in a secure, isolated environment. For example, you can run and use a Windows 10 instance on a macOS Catalina machine or the other way around.

Virtual machine technology is used for many use cases across on-premises and cloud environments. More recently, public cloud servicesare using virtual machines toprovide virtual application resourcesto multiple users at once, for even more cost efficient and flexible compute.

What are virtual machines used for?

Virtual machines(VMs) allow a business to run an operating system that behaves like a completely separate computer in an app window on a desktop. VMsmay be deployed to accommodate different levels of processing power needs, to run software that requires a different operating system, or to test applications in a safe, sandboxed environment.

Virtual machines have historically been used forserver virtualization, which enables IT teams to consolidate their computing resources and improve efficiency. Additionally, virtual machines can perform specific tasks consideredtoo risky to carry out in a host environment, such as accessing virus-infected data or testing operating systems. Since the virtual machine is separated from the rest of the system, the software inside the virtual machine cannot tamper with the host computer.

How do virtual machines work?

The virtual machine runs as a process in an application window, similar to any other application, on the operating system of the physical machine. Key files that make up a virtual machine include a log file, NVRAM setting file, virtual disk file and configuration file.

Advantages of virtual machines

Virtual machines are easy to manage and maintain, and they offer several advantages over physical machines:

VMs can run multiple operating system environments on a single physical computer, saving physical space, time and management costs.

Virtual machines support legacy applications, reducing the cost of migrating to a new operating system. For example, aLinux virtual machine running a distribution of Linux as the guest operating system can exist on a host server that is running a non-Linux operating system, such as Windows.

VMs can also provide integrateddisaster recoveryand application provisioning options.

Disadvantages of virtual machines

While virtual machines have several advantages over physical machines, there are also some potential disadvantages:

Running multiple virtual machines on one physical machine can result in unstable performance if infrastructure requirements are not met.

Virtual machines are less efficient and run slower than a full physical computer. Most enterprises use a combination of physical and virtual infrastructure to balance the corresponding advantages and disadvantages.

The two types of virtual machines

Users can choose from two different types of virtual machines—process VMs and system VMs:

A process virtual machineallows a single process to run as an application on a host machine, providing a platform-independent programming environment by masking the information of the underlying hardware or operating system. An example of a process VM is the Java Virtual Machine, which enables any operating system to run Java applications as if they were native to that system.

A system virtual machineis fully virtualized to substitute for a physical machine. A system platform supportsthe sharing of a host computer’s physical resources between multiple virtual machines, each running its own copy of the operating system. This virtualization process relies on ahypervisor, which can run on bare hardware, such as VMware ESXi,or on top of an operating system.

What are 5 types ofvirtualization?

All the components of a traditional data center or IT infrastructure can be virtualized today, with various specific types of virtualization:

Hardware virtualization:When virtualizing hardware, virtual versions of computers and operating systems (VMs) are created and consolidated into a single, primary, physical server. A hypervisor communicates directly with a physical server’s disk space and CPU to manage the VMs. Hardware virtualization, which is also known as server virtualization, allows hardware resources to be utilized more efficiently and for one machine to simultaneously run different operating systems.

Software virtualization:Software virtualization creates a computer system complete with hardware that allows one or more guest operating systems to run on a physical host machine. For example, Android OS can run on a host machine that is natively using a Microsoft Windows OS, utilizing the same hardware as the host machine does.Additionally, applications can be virtualized and delivered from a server to an end user’s device, such as a laptop or smartphone. This allowsemployees to accesscentrally hosted applications when working remotely.

Storage virtualization:Storage can be virtualized by consolidating multiple physical storage devices to appear as a single storage device. Benefits include increased performance and speed, load balancing and reduced costs. Storage virtualization also helps with disaster recovery planning, as virtual storage data can be duplicated and quickly transferred to another location, reducing downtime.

Network virtualization:Multiple sub-networks can be created on the same physical network by combiningequipment into a single, software-based virtual network resource. Network virtualization also divides available bandwidth into multiple, independent channels, each of which can be assigned to servers and devices in real time. Advantages include increased reliability, network speed,security and better monitoring of data usage. Network virtualization can be a good choice for companies with a high volume of users who need access at all times.

Desktop virtualization:This common type of virtualization separates the desktop environment from the physical device and stores a desktop on a remote server, allowing users to access their desktops from anywhere on any device. In addition to easy accessibility, benefits of virtual desktops includebetter data security, cost savingson software licenses and updates, andease of management.

Container vs virtual machine

Likevirtual machines, container technology such as Kubernetesissimilar in the sense of running isolated applications on a single platform. While virtual machines virtualize the hardwarelayer to create a “computer,”containers package up just a single app along with its dependencies.Virtual machines are often managed by a hypervisor, whereas container systems provide shared operating system services from the underlying host and isolate the applications using virtual-memory hardware.

A key benefit of containersis that they have less overhead compared to virtual machines. Containers include only the binaries, libraries and other required dependencies, and the application. Containers that are on the same host share the same operating systemkernel, making containers much smaller than virtual machines.As a result,containers boot faster, maximize server resources,and makedelivering applicationseasier. Containershave become popluar foruse cases such as web applications, DevOps testing, microservices and maximizing the number of apps that can be deployed per server.

Virtual machinesare larger and slower to boot than containers. They are logically isolated from one another, with their own operating system kernel, and offer the benefits of a completely separate operating system. Virtual machines are best for running multiple applications together, monolithic applications, isolation between apps, and for legacy apps running on older operating systems.Containers and virtual machines may also be used together.

Setting up a virtual machine

Virtual machines can be simple to set up, and there are many guides online that walk users through the process. VMware offers one such usefulvirtual machine set-up guide.

Hackintoshes – PCs tweaked to run macOS with workarounds have been around for a while. But as Apple only wants its software to run on its own devices, it’s become more difficult over time to actually use them as functional machines. Now a new type of Hackintosh appears to be gaining some traction that may be useful for research and educational purposes, virtual Hackintoshes. Interestingly, a video of an iPad running macOS has just surfaced as the latest virtual Hackintosh.

On YouTube, Yevgen Yakovliev shared an almost 40-minute walkthrough of what appears to be macOS Catalina running on a 2020 iPad Pro. Notably, this isn’t a method of running macOS Big Sur on the iPad Pro’s A12Z ARM chip.

Yevgen is using the UTM app to run virtual machines on iOS devices, then has employed a process to create a virtual Hackintosh with a method shared on GitHub called OSX-KVM. KVM is an open source Kernel-based Virtual Machine utility built into Linux.

Described by RedHat: “Specifically, KVM lets you turn Linux into a hypervisor that allows a host machine to run multiple, isolated virtual environments called guests or virtual machines (VMs).”

Notably, Kholia who posted the OSX-KVM resources on GitHub notes in the README that they are looking for help documenting the process of “running macOS on popular cloud providers (Hetzner, GCP, AWS).” It’s possible this example of macOS Catalina running on iPad could be a cloud-based Virtual Hackintosh.

As for the legality of all this, Kholia shared the following:

The “secret” Apple OSK string is widely available on the Internet. It is also included in a public court document available here. I am not a lawyer but it seems that Apple’s attempt(s) to get the OSK string treated as a trade secret did not work out. Due to these reasons, the OSK string is freely included in this repository.

Please review the ‘Legality of Hackintoshing’ documentation bits from Dortania’s OpenCore Install Guide.

Gabriel Somlo also has some thoughts on the legal aspects involved in running macOS under QEMU/KVM.

You may also find this ‘Announcing Amazon EC2 Mac instances for macOS’ article interesting.

This is similar for macOS to what Apple took Correllium to court over with the latter offering iOS virtualization. Just last month, Corellium won part of the lawsuit.

Kholia also highlights:

My aim is to enable macOS based educational tasks, builds + testing, kernel debugging, reversing, and macOS security research in an easy, reproducible manner without getting ‘invested’ in Apple’s closed ecosystem (too heavily).

These Virtual Hackintosh systems are not intended to replace the genuine physical macOS systems.

Yergen also cited this post on virtualizing OpenCore and x86 as helpful in their work to get macOS working on the iPad Pro.

L2 bridging with VMware NSX-T

by Michal Grzeszczak

My name is Michal Grzeszczak and I am a senior consultant at Xtravirt (www.xtravirt.com), an independent cloud consulting business and VMware Master Services Competent Partner. In this blog, I’d like to share with you my experience of L2 bridging with VMware® NSX-T Data Center and help you to understand some of the differences between NSX-T and NSX-V, as well as cover some NSX use cases.

Customer background:

The customer is one of the leading organisations in the betting and gambling industry and have been using NSX-V for some time now. When it came to their new greenfield environment, they decided to deploy NSX-T 2.4 Data Center. This decision was largely based on the fact that NSX-T Data Center provides bridging firewalls natively for L2 software bridging, which was their main requirement. Also, given that NSX-T will be the de facto network and security virtualisation platform offered by VMware going forward, by specifying it for this environment the customer is able to future proof the deployment.

Future upgrades are also accounted for as upgrading from NSX-T 2.4 to future NSX-T releases is simpler than performing upgrades from a previous version of V or T.

NSX-T 2.4 was a major update and brought many changes to the architecture of the product, the main ones being:

The NSX Manager and NSX Controllers were merged into one appliance deployed in a Cluster of 3 Nodes therefore minimising the footprint of the solution and operational complexity.

The other major change was the introduction of the new Simplified UI which “requires just the bare minimum of user input, offering strong default values with prescriptive guidance for ease of use. This means fewer clicks and page hops are required to complete configuration tasks.”

NOTE: In NSX 2.4 two UIs are presented - one is the new Simplified UI, the other one is Advanced. The latter is taken from NSX-T 2.3. The future plan is to remove the Advanced UI and provide all of the functionality via the Simplified UI.

What are the key benefits of choosing NSX-T over NSX-V?

There are many benefits of NSX-T over NSX-V, to name a few:

NSX-T doesn’t require vCenter, however it can be added to NSX-T as a Compute Manager and allows for up to 16 Compute Managers per NSX 2.4 solution . There is no longer a 1:1 requirement like there was with NSX-V.

KVM Hypervisor support

Bare Metal Edges provide sub-second failover

Data Plane Development Kit (DPDK) Optimising Forwarding - DPDK is a set of data plane libraries and network interface controller drivers for fast packet processing

New, more flexible Overlay technology - Geneve replaces VXLAN https://docs.vmware.com/en/VMware-Validated-Design/4.3/com.vmware.vvd.sddc-nsxt-design.doc/GUID-CF3C47CA-9BEB-4213-8F08-1494261BF3EC.html

Bi-directional Forwarding Detection support

BGP (Border Gateway Protocol) expanded functionality with features like Route Maps

Much clearer User Interface (UI)

What were the specific use cases for this case customer and the design considerations?

USE CASE 1 - NSX-T Edge L2 Bridging - Integration of physical, non-virtualised database servers that require L2 connectivity to the virtualised environment.

Design considerations:

In NSX-T 2.4 two options are possible to bridge L2 workloads - using ESXi Bridge Clusters or Edge Bridge Profiles. The latter is recommended to use as the former will be deprecated in future.

Ideally the use of dedicated Bare Metal Edges, however this is not a requirement.

The possibility to deploy Edge Bridges in collapsed vSphere Clusters > Management + Edge or Compute + Edge

Consider having active and standby Edge Nodes on different hosts to avoid throughput drop, because VLAN traffic needs to be forwarded to both Edge Nodes in promiscuous mode.

Overlay traffic can be tagged on a Distributed Port Group or Uplink Profile, but please avoid double tagging.

VLAN traffic should not be tagged on the Uplink Profile.

Distributed Port Group for VLAN traffic connecting to the Edge Node should be in a Trunk Mode. The reason for this is due to the fact that Edge doing Bridging adds 802.1Q tag when transposing Overlay traffic to VLAN.

Consider having the same MTU value across your environment - if you can, choose MTU of 9000 for better performance.

Several Bridge Profiles can be configured, and a given Edge can belong to several Bridge Profiles. By creating two separate Bridge Profiles, alternating active and backup Edge in the configuration, the user can easily make sure that two Edge nodes simultaneously bridge traffic between Overlay and VLAN

Constraints:

Edge Cluster with minimum 2 Edge Nodes in Active/Standby mode is needed.

Standby uplinks are not supported on the Edge Node.

Source Based Load Based Teaming is not supported on the Edge Node.

The port group on the VSS/VDS sending and receiving traffic on the VLAN side should be in promiscuous mode, allowing MAC Address changes and Forge Transmits.

Deployment:

Follow the deployment guide here - https://youtu.be/IwpujflzJhY

Or here https://docs.vmware.com/en/VMware-NSX-T-Data-Center/2.3/com.vmware.nsxt.admin.doc/GUID-7B21DF3D-C9DB-4C10-A32F-B16642266538.html

Validation:

Type “nsxcli”.

“Get l2bridge-ports-config” will show the Bridge Port State (Active Edge will have Forwarding, Standby will have Stopped), VLAN ID configured and Bridge UUID which can be copied and used to do a packet capture on the Edge Node.

To do the packet capture type “start capture interface “copied Bridge UUID” and hit enter, ping from VM to Physical Server to see the flows.

USE CASE 2 - NSX bridging firewall - Secure communication between physical database servers and Overlay workloads.

The configuration of the bridging firewall can be done currently only on the Advanced UI.

Security rules are configured per Logical Switch aka Segment in Simplified UI.

NSX-T grouping objects like NSGroups can be used to provide abstraction from the IP based approach.

USE CASE 3 - vRealize Network Insight - Monitoring tool that can provide visibility into both Physical and Virtual environments.

NSX-T 2.4 is fully supported with the latest vRealize Network Insight version 4.1.

Make sure you are allowing ports for communication between vRNI and other devices after the deployment. For example, ESXi Hosts to vRNI Collector on UDP 2055. The full list of ports needed can be found here - https://docs.vmware.com/en/VMware-vRealize-Network-Insight/3.9/com.vmware.vrni.install.doc/GUID-FDDA5F2F-7C3B-472A-A17D-39582FBD5996.html

There is a new website that provides in-depth information about new features in vRNI, definitely worth visiting - https://vrealize.vmware.com/t/vmware-network-management/

What were the outcomes?

Overall, this deployment was a complete success as we were able to satisfy all of the requirements that the customer had. All the production physical databases were able to communicate on the same L2 segments, virtualised and connected to NSX-T segments workloads. On top of that, communication between those workloads was secured by NSX-T Bridging Firewall. vRealize Network Insight was used to provide visibility into the environment. Its ability to quickly troubleshoot network and firewall related issues in both virtual and physical realms allows admins to take a breath in the never-ending battle of making the networks stable.

I hope you enjoyed my blog, if you’d like to talk to Xtravirt about your business’s networking and security requirements, then please send an email to [email protected]

VMware vSphere ESXi 7 Kurulumu

Merhaba,

VMware vSphere ESXi 7 Kurulumu isimli bu makalemde sizlere yeni çıkan ESXi 7 sürümünün kurulumunu anlatacağım. Aslında bir önceki versiyondan bir farkı bulunmuyor ancak yinede merak eden kişilere rehber olacağını düşünüyorum.

VMware vSphere ESXi 7 Kurulumuna başlamadan önce, vSphere 7 ile birlikte gelen yenilikleri incelemenizi tavsiye ederim. Bunun için aşağıdaki linkleri inceleyebilirsiniz.

VMware vSphere ESXi 7 Kurulumu

vCenter Server 7 Upgrade Öncesi

vSphere 7 DRS Yenilikleri

vCenter Server 7 Yenilikleri

vSphere 7 Yenilikleri

vSphere 6.7 vs vSphere 7

VSAN 7 Yenilikleri

ESXi 7 Hardware Gereksinimleri:

ESXi host’un kurulacağı sunucuda minimum 2 core bulunmalıdır.

Eylül 2006’dan sonra release olan 64-bit X86 CPU’lar support edilmektedir. Support edilen işlemciler ile ilgili http://www.vmware.com/resources/compatibility link’ini inceleyebilirsiniz.

BIOS üzerinden CPU ‘da bulunan NX/XD değerlerinin enable olması gerekmektedir.

ESXi 7 için minimum 4GB fiziksel memory gerekmektedir. Ancak önerilen memory miktarı 8GB’dır.

ESXi 7’nin kurulacağı sunucu üzerinde hardware virtualization support edilmelidir. (Intel VT-x veya AMD RVI)

1 veya daha fazla gigabit veya fast ethernet olmalıdır. Support edilen network kart’ları için http://www.vmware.com/resources/compatibility adresini inceleyebilirsiniz.

ESXi 7 Storage Gereksinimleri:

ESXi 7 kurulumu veya upgrade’i için minimum 8 GB boyutunda bir boot device bulunmalıdır. Eğer USB veya SD kart harici bir yere kurulum yapacaksanız 32 GB free space olması önerilmektedir. ESXi host’u doğrudan USB veya SD kart üzerine kurabililrsiniz. Ancak bu işlemi yaptıkdan sonra scratch bölümü USB veya SD kart üzerinde oluşmaz. Bunun sebebi yoğun IO taleplerini USB veya SD kartın karşılayamamasından kaynaklanmaktadır. Eğer ESXi host üzerinde local bir diske kurulum yapmıyorsanız SD veya USB aygıtlara kurulum yapıyorsanız scratch partition’ı ramdisk üzerinde oluşturulur. SD veya USB aygıt üzerine kurulum yaptıysanız kurulum veya upgrade’den sonra yine scratch partition’ın ayarlanması gerekmektedir.

Konu ile ilgili aşağıdaki link incelenebilir.

http://kb.vmware.com/kb/2004784

ESXi 7 için support edilen Remote Management Server Model’leri aşağıdaki gibidir.

Remote Management Server Model Firmware Version Java Dell DRAC 7 1.30.30 (Build 43) 1.7.0_60-b19 Dell DRAC 6 1.54 (Build 15), 1.70 (Build 21) 1.6.0_24 Dell DRAC 5 1.0, 1.45, 1.51 1.6.0_20,1.6.0_203 Dell DRAC 4 1.75 1.6.0_23 HP ILO 1.81, 1.92 1.6.0_22, 1.6.0_23 HP ILO 2 1.8, 1.81 1.6.0_20, 1.6.0_23 HP ILO 3 1.28 1.7.0_60-b19 HP ILO 4 1.13 1.7.0_60-b19 IBM RSA 2 1.03, 1.2 1.6.0_22

Performans için ESXi host önerileri:

Aşağıdaki bilgiler doğrultusunda ESXi host üzerinden daha fazla performans alabilirsiniz.

Memory:

ESXi host üzerinde bulunan 8GB memory ile ESXi ‘in tüm özelliklerini kullanabilir ve üzerine küçük virtual machine’ler oluşturabilrisiniz. Virtual machine sayısına ve bunların memory boyutlarına göre ESXi host üzerinde daha fazla memory gereksinimi olabilir. Bunun için ESXi host üzerinde çalışacak virtual machine sayısına göre fizik sunucuya memory yatırımı yapmalısınız.

Network card:

Management ve virtual machine network’u için farklı fiziksel network kartları kullanmalısınız. Virtual machine network’unde gigabit network kartı kullanmanız virtual machine’lerin daha yüksek network trafiği kullanmasına olanak verir.

Disk:

Virtual machine’lerinizi özellikle virtual machine’ler için ayrılan datastore’larda barındırın. ESXi host’un kurulu olduğu local disk’e mümkün olduğu kadar virtual machine kurmayın. Böylece performans probleminden en az etkilenmiş olursunuz.

VMFS:

ESXi ‘i kurduğunuz disk eğer local disk ise bu alan kurulum esnasında otomatik olarak VMFS formatına dönüştürülür. Eğer ekstra disk eklerseniz bunu vSphere Web Client’i kullanarak formatlamanız gerekmektedir.

Processors:

Hızlı CPU kullanılması ESXi host’un performansını iyileştirir. Yoğun yük altında yüksek cache’li CPU’lar kullanılması tavsiye edilmektedir.

Hardware compatibility:

Support edilen ESXi 7 driver’ları ile ilgili aşağıdaki link’i inceleyebilirsiniz.

http://www.vmware.com/resources/compatibility

Port Gereksinimleri:

ESXi host’un üzerinde basit bir firewall bulunmaktadır. Bu firewall gerektiği anda ESXi host üzerindeki port’ları açıp kapatabilir.

Incoming Firewall Connections Port Protocol Service Description 5988 TCP CIM Server Server for CIM (Common Information Model). 5989 TCP CIM Secure Server Secure server for CIM. 427 TCP, UDP CIM SLP The CIM client uses the Service Location Protocol, version 2 (SLPv2) to find CIM servers. 546 DHCPv6 DHCP client for IPv6. 8301, 8302 UDP DVSSync DVSSync ports are used for synchronizing states of distributed virtual ports between hosts that have VMware FT record/replay enabled. Only hosts that run primary or backup virtual machines must have these ports open. On hosts that are not using VMware FT these ports do not have to be open. 902 TCP NFC Network File Copy (NFC) provides a file-type-aware FTP service for vSphere components. ESXi uses NFC for operations such as copying and moving data between datastores by default. 12345, 23451 UDP vSAN Clustering Service VMware vSAN Cluster Monitoring and Membership Directory Service. Uses UDP-based IP multicast to establish cluster members and distribute vSAN metadata to all cluster members. If disabled, vSAN does not work. 68 UDP DHCP Client DHCP client for IPv4. 53 UDP DNS Client DNS client. 8200, 8100, 8300 TCP, UDP Fault Tolerance Traffic between hosts for vSphere Fault Tolerance (FT). 6999 UDP NSX Distributed Logical Router Service NSX Virtual Distributed Router service. The firewall port associated with this service is opened when NSX VIBs are installed and the VDR module is created. If no VDR instances are associated with the host, the port does not have to be open.

This service was called NSX Distributed Logical Router in earlier versions of the product.

2233 TCP vSAN Transport vSAN reliable datagram transport. Uses TCP and is used for vSAN storage IO. If disabled, vSAN does not work. 161 UDP SNMP Server Allows the host to connect to an SNMP server. 22 TCP SSH Server Required for SSH access. 8000 TCP vMotion Required for a virtual machine migration with vMotion. ESXi hosts listen on port 8000 for TCP connections from remote ESXi hosts for vMotion traffic. 8080 TCP vsanvp vSAN VASA Vendor Provider. Used by the Storage Management Service (SMS) that is part of vCenter to access information about vSAN storage profiles, capabilities, and compliance. If disabled, vSAN Storage Profile Based Management (SPBM) does not work. 80 TCP vSphere Web Access Welcome page, with download links for different interfaces. 5900 -5964 TCP RFB protocol 80, 9000 TCP vSphere Lifecycle Manager 9080 TCP I/O Filter Service Used by the I/O Filters storage feature.

Outgoing Firewall Connections Port Protocol Service Description 427 TCP, UDP CIM SLP The CIM client uses the Service Location Protocol, version 2 (SLPv2) to find CIM servers. 547 TCP, UDP DHCPv6 DHCP client for IPv6. 8301, 8302 UDP DVSSync DVSSync ports are used for synchronizing states of distributed virtual ports between hosts that have VMware FT record/replay enabled. Only hosts that run primary or backup virtual machines must have these ports open. On hosts that are not using VMware FT these ports do not have to be open. 44046, 31031 TCP HBR Used for an ongoing replication traffic by vSphere Replication and VMware Site Recovery Manager. 902 TCP NFC Network File Copy (NFC) provides a file-type-aware FTP service for vSphere components. ESXi uses NFC for operations such as copying and moving data between datastores by default. 9 UDP WOL Used by Wake on LAN. 12345 23451 UDP vSAN Clustering Service Cluster Monitoring, Membership, and Directory Service used by vSAN. 68 UDP DHCP Client DHCP client. 53 TCP, UDP DNS Client DNS client. 80, 8200, 8100, 8300 TCP, UDP Fault Tolerance Supports VMware Fault Tolerance. 3260 TCP Software iSCSI Client Supports software iSCSI. 6999 UDP NSX Distributed Logical Router Service The firewall port associated with this service is opened when NSX VIBs are installed and the VDR module is created. If no VDR instances are associated with the host, the port does not have to be open. 5671 TCP rabbitmqproxy A proxy running on the ESXi host. This proxy allows applications that are running inside virtual machines to communicate with the AMQP brokers that are running in the vCenter network domain.

The virtual machine does not have to be on the network, that is, no NIC is required. Ensure that outgoing connection IP addresses include at least the brokers in use or future. You can add brokers later to scale up.

2233 TCP vSAN Transport Used for RDT traffic (Unicast peer to peer communication) between vSAN nodes. 8000 TCP vMotion Required for virtual machine migration with vMotion. 902 UDP VMware vCenter Agent vCenter Server agent. 8080 TCP vsanvp Used for vSAN Vendor Provider traffic. 80, 9000 TCP vSphere Lifecycle Manager

Yukarıdaki gereksinimleri karşıladıktan sonra artık ESXi kurulumunu yapabiliriz. Bunun için aşağıdaki link’den indirdiğimiz ISO’yu sunucumuza mount ediyoruz.

vSphere 7 Release Oldu!

Yukarıdaki linkten ESXi 7 ISO Download ediyoruz. ISO download ettikten sonra fiziksel sunucumuza mount ediyoruz.

ISO’dan sunucuyu boot ettikten sonra karşımıza aşağıdaki gibi boot ekranı gelecektir.

VMware vSphere ESXi 7 Kurulumu

ESXi boot oluyor. Normal şartlarda burada ESXİ boot ekranı gelmesi gerekiyor ancak ESXi 7 ile birlikte bu kaldırılmış. Doğrudan ISO üzerinden boot oluyor.

VMware vSphere ESXi 7 Kurulumu

ESXi 7 kurulum ekranında Enter butonu ile kuruluma başlıyoruz.

VMware vSphere ESXi 7 Kurulumu

Kullanıcı sözleşmesini kabul etmek için F11 butonunu kullanıyoruz.

VMware vSphere ESXi 7 Kurulumu

ESXi 7 ‘nin kurulacağı disk’i seçiyoruz ve Enter butonuna basıyoruz. Burada VMFS3 datastore’larınız var ise bunlar otomatik olarak VMFS5 ‘e upgrade edilecektir.

Klavye dil seçeneklerini ben genellikle Default olarak bırakıyorum. Eğer ILO, IDRAC gibi yerlerden kurulum yapıyorsanız bazen klavye dil seçeneklerini değiştirmeniz gerekebiliyor. Ancak default bırakmanıza bir sakınca bulunmuyor.

Enter ile devam ediyoruz.

VMware vSphere ESXi 7 Kurulumu

ESXi 7 için root şifresi belirtiyoruz. ESXi 7 ‘nin root şifresini kaybetmeniz durumunda yeniden kurmaktan başka bir çözümünüz bulunmuyor. Official olarak önerilen tek yöntem yeniden kurmaktır. Yeniden kurulum esnasında veri kaybı yaşamazsınız.

Root şifresini belirttikten sonra Enter butonu ile devam ediyoruz.

VMware vSphere ESXi 7 Kurulumu

Yapmış olduğumuz işlemleri F11 butonu ile onaylayıp kuruluma başlıyoruz. ESXi 7’nin kurulumu oldukça kısa bir süre içerisinde tamamlanacaktır. Hatta bana sorarsanız daha önceki ESXi sürümlerine göre daha hızlı kuruluyor 🙂

VMware vSphere ESXi 7 Kurulumu

VMware vSphere ESXi 7 Kurulumu başlıyor. Kurulum süresi sahip olduğunuz fiziksel donanım’ın özelliklerine göre değişkenlik gösterecektir.

VMware vSphere ESXi 7 Kurulumu

VMware vSphere ESXi 7 Kurulumu tamamlandıktan sonra Enter butonu ile ESXi 7 ‘nin kurulumunu tamamlıyoruz.

ESXi 7 kurulumu tamamlandıktan sonra ve ESXi 7 açıldıktan sonra artık F2 butonu ile IP konfigurasyonun yapabiliriz. Bunun için F2 butonuna basıyoruz ve Configure Network bölümünden ESXi 7 ‘nin network ayarlarını yapıyoruz.

ESXi ‘in önceki sürümlerinde vSphere Client kaldırıldığı için tüm işlemlerimizi browser üzerinden gerçekleştiriyorduk. Bu versiyonda da aynı şekilde browser üzerinden erişim sağlıyoruz.

ESXi 7 kurulumu tamamlandıktan sonra browser üzerinden erişim sağlayabilir ve versiyon bilgisini kontrol edebilirisniz.

Kurulumu sırasında mutlaka ve mutlaka Custom ESXi ISO kullanmanızı tavsiye ederim. Daha önce Custom ESXi ISO ile ilgili makaleme aşağıdaki linkten ulaşabilirsiniz.

Neden Custom ESXi ISO Kullanmalıyız?

Umarım faydalı olmuştur.

İyi çalışmalar.
