Instalación y Configuración de dnscrypt-proxy + dnsmasq en Archlinux Actualizado

Para los que no sepan qué es y como funciona dnscrypt-proxy y dnsmasq dejo aquí un link con información al respecto. Ésa guía de instalación y configuración es con una versión antigua, asi que por favor en el caso que usen ésa versión sigan ése tutorial, sinó continuamos aquí.

Comencemos!

1 – Instalamos los paquetes necesarios, ósea dnscrypt-proxy y dnsmasq:

# pacman dnscrypt-proxy dnsmasq

Here is the Complete guide on how to install KVM, QEMU and Virt Manager on Arch Linux and Manjaro. KVM is one of the most used Virtualization software in Linux World. In fact, most cloud providers use KVM as their Hypervisor of choice. Big projects including Openstack use KVM as default Virtualization tool. In this tutorial, we’ll install KVM on Arch Linux and set Kernel modules required to automatically load at boot. We’ll also install a guest machine running CentOS 7. Our previous tutorials on KVM include: Create and Configure Bridge Networking For KVM in Linux How To Clone and Use KVM Virtual Machine in Linux How to extend/increase KVM Virtual Machine (VM) disk size Step 1: Install KVM packages First step is installing all packages needed to run KVM: sudo pacman -Syy sudo reboot sudo pacman -S archlinux-keyring sudo pacman -S qemu virt-manager virt-viewer dnsmasq vde2 bridge-utils openbsd-netcat Also install ebtables  and iptables packages: sudo pacman -S ebtables iptables Step 2: Install libguestfs on Arch Linux / Manjaro libguestfs is a set of tools used to access and modify virtual machine (VM) disk images. You can use this for: viewing and editing files inside guests scripting changes to VMs monitoring disk used/free statistics creating guests P2V V2V performing backup e.t.c sudo pacman -S libguestfs Step 3: Start KVM libvirt service Once the installation is done, start and enable libvirtd service to start at boot: sudo systemctl enable libvirtd.service sudo systemctl start libvirtd.service Status show it’s running: $ systemctl status libvirtd.service ● libvirtd.service - Virtualization daemon Loaded: loaded (/usr/lib/systemd/system/libvirtd.service; enabled; vendor preset: disabled) Active: active (running) since Thu 2019-04-18 20:55:34 EAT; 11h ago Docs: man:libvirtd(8) https://libvirt.org Main PID: 646 (libvirtd) Tasks: 26 (limit: 32768) Memory: 74.0M CGroup: /system.slice/libvirtd.service ├─ 646 /usr/bin/libvirtd ├─ 754 /usr/bin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/default.conf --leasefile-ro --dhcp-script=/usr/lib/libvirt/libvirt_leases> ├─ 755 /usr/bin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/default.conf --leasefile-ro --dhcp-script=/usr/lib/libvirt/libvirt_leases> ├─ 777 /usr/bin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/docker-machines.conf --leasefile-ro --dhcp-script=/usr/lib/libvirt/libvir> ├─ 778 /usr/bin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/docker-machines.conf --leasefile-ro --dhcp-script=/usr/lib/libvirt/libvir> ├─25924 /usr/bin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/vagrant-libvirt.conf --leasefile-ro --dhcp-script=/usr/lib/libvirt/libvir> ├─25925 /usr/bin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/vagrant-libvirt.conf --leasefile-ro --dhcp-script=/usr/lib/libvirt/libvir> ├─25959 /usr/bin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/fed290.conf --leasefile-ro --dhcp-script=/usr/lib/libvirt/libvirt_leasesh> └─25960 /usr/bin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/fed290.conf --leasefile-ro --dhcp-script=/usr/lib/libvirt/libvirt_leasesh> Step 4: Enable normal user account to use KVM Since we want to use our standard Linux user account to manage KVM, let’s configure KVM to allow this. Open the file /etc/libvirt/libvirtd.conf for editing. sudo pacman -S vim sudo vim /etc/libvirt/libvirtd.conf Set the UNIX domain socket group ownership to libvirt, (around line 85) unix_sock_group = "libvirt" Set the UNIX socket permissions for the R/W socket (around line 102) unix_sock_rw_perms = "0770" Add your user account to libvirt group. sudo usermod -a -G libvirt $(whoami) newgrp libvirt Restart libvirt daemon. sudo systemctl restart libvirtd.service Step 5: Enable Nested Virtualization (Optional) Nested Virtualization feature enables you to run Virtual Machines inside a VM.

Enable Nested virtualization for kvm_intel / kvm_amd by enabling kernel module as shown. ### Intel Processor ### sudo modprobe -r kvm_intel sudo modprobe kvm_intel nested=1 ### AMD Processor ### sudo modprobe -r kvm_amd sudo modprobe kvm_amd nested=1 To make this configuration persistent,run: echo "options kvm-intel nested=1" | sudo tee /etc/modprobe.d/kvm-intel.conf Confirm that Nested Virtualization is set to Yes: ### Intel Processor ### $ systool -m kvm_intel -v | grep nested nested = "Y" nested_early_check = "N" $ cat /sys/module/kvm_intel/parameters/nested Y ### AMD Processor ### $ systool -m kvm_amd -v | grep nested nested = "Y" nested_early_check = "N" $ cat /sys/module/kvm_amd/parameters/nested Y Step 6: Using KVM on Arch Linux / Manjaro You have successfully installed KVM, QEMU and Virt Manager on Arch Linux and Manjaro. You are now good to go. You can install a Linux or Windows OS Virtual Machine and build your study labs.
