I just spent 2 hours figuring this out, so here is how you forward a USB device directly to a QEMU VM on Linux:

Use lsusb to find the bus and device numbers (such as 001 and 008)

Make that device available to KVM: sudo chgrp kvm /dev/bus/usb/001/008 (source)

Start QEMU like so: qemu-system-x86_64 ... -usb -device usb-host,hostbus=1,hostaddr=8 (source)

Context: I was trying to use a USB gamepad within a Windows 2000 VM, but it didn't show up until I did the chgrp step.

Porady Admina: chgrp

W kolejnym tutorialu z cyklu Porady Admina zajmiemy się programem chgrp https://linuxiarze.pl/porady-admina-coreutils-chgrp/

[snarp]

I think it is probably Fucked Up that there are blog posts I wrote for stuff like "How To Use chgrp And chmod To Fix A Common Problem" or "How To SFTP Into The Webbed Site" over a decade ago - primarily for my own reference and that of like 2-3 people I knew personally - that people are still fucking sharing around on message boards and Discord, finding via Google, etc etc. A tutorial I wrote for a specific task in a now-abandoned piece of gamedev software has been translated into at least two languages.

Like, there are people out there learning tech skills on my old blog with the broken anime backgrounds, INSTEAD of in the documentation hosted by Google or MS or textbook publishers. And there are many abandoned blogs, often with anime backgrounds, through which people are learning things that are not made clear enough to them in more-official educational sources. Some of these posts must now be accessed via Wayback. That is Fucked Up. Tech education... is Fucked Up. This is my thesis.

Установка и настройка QEMU/KVM в Ubuntu

В этой статье я хочу рассмотреть установку и настройку QEMU/KVM в Ubuntu.

Оглавление

ВведениеПроверка аппаратной поддержкиПодготовка сервераУстановка и запускНастройка сетиНастройка сетевого мостаВиртуальные сети (NAT forwarding)Создание виртуальной машиныУправление виртуальной машиной Введение в QEMU/KVM KVM (Kernel-based Virtual Machine) — это комплекс программ для виртуализации с аппаратной поддержкой в среде Linux x86. Виртуализация позволяет нам устанавливать полностью изолированные, но работающие бок о бок операционные системы на одном и том же железе. Гипервизор KVM представляет из себя загружаемый модуль ядра Linux. Он обеспечивает только уровень абстракции устройств. Таким образом одного гипервизора KVM недостаточно для запуска виртуальной ОС. Нужна еще эмуляция процессора, дисков, сети, видео, шины. Для этого существует QEMU. QEMU (Quick Emulator) — эмулятор различных устройств, который позволяет запускать операционные системы, предназначенные для одной архитектуры, на другой. Обычно такой комплекс программ для виртуализации называют QEMU/KVM. Проверка аппаратной поддержки виртуализации Во-первых, перед настройкой KVM необходимо проверить совместимость сервера с технологиями виртуализации: cat /proc/cpuinfo | egrep -c "(vmx|svx)" Числа отличные от нуля говорят о том, что процессор имеет поддержку аппаратной виртуализации Intel-VT или AMD-V . Подготовка сервера Во-вторых, для удобства создадим каталоги для хранения образов жестких дисков наших виртуальных машин и образов ISO, с которых будет производиться установка операционных систем. sudo mkdir -p /kvm/{hdd,iso} В результате будет создан каталог /kvm/hdd для виртуальных жестких дисков и каталог /kvm/iso для образов ISO. Установка и запуск QEMU/KVM в Ubuntu В качестве интерфейса к технологиии виртуализации QEMU/KVM в Ubuntu мы будем использовать библиотеку libvirt. С помощью следующей команды мы установим гипервизор, эмулятор, библиотеку и утилиты управления. sudo apt-get install qemu-kvm libvirt-bin virtinst libosinfo-bin Где qemu-kvm — сам гипервизор; libvirt-bin — библиотека управления гипервизором; virtinst — утилита управления виртуальными машинами; libosinfo-bin — утилита для просмотра списка вариантов гостевых операционных систем. После успешной установки всех пакетов настроим автоматический запуск сервиса. sudo systemctl enable libvirtd Запустим его. sudo systemctl start libvirtd Пользователя, под которым будем работать с виртуальными машинами, включим в группу libvirt: sudo usermod -aG libvirt user И установим права доступа на ранее созданные каталоги: sudo chgrp libvirt /kvm/{hdd,iso} sudo chmod g+w /kvm/hdd Настраивать виртуальные машины, хранилища и сети можно как из командной строки, так и с помощью GUI-инструмента virt-manager. Причем установить его можно как на сервер, так и на другой компьютер, например, на ваш ноутбук. В последнем случае вам придется добавить удаленное соединение к libvirt. Установку virt-manager и работу при помощи него с libvirt и виртуальными машинами мы рассмотрим в следующей статье. Настройка сети Итак, виртуальные машины могут работать через свою виртуальную сеть с NAT или получать IP-адреса из локальной сети через сетевой мост, который нам необходимо настроить. Настройка сетевого моста В старых версиях Ubuntu большая часть настроек конфигурации сети Ethernet находится в файле /etc/network/interfaces. На всякий случай создадим его резервную копию: mkdir -p ~/backup && sudo cp /etc/network/interfaces ~/backup Затем устанавливаем утилиты для конфигурирования Ethernet-моста: sudo apt-get install bridge-utils Открываем файл /etc/network/interfaces в своем любимом редакторе (vim, nano): sudo vim /etc/network/interfaces И приводим его к примерно такому виду: source /etc/network/interfaces.d/* auto lo iface lo inet loopback #allow-hotplug eno1 #iface eno1 inet static # address 192.168.7.2/24 # gateway 192.168.7.1 # dns-nameservers 127.0.0.1 192.168.7.1 8.8.8.8 # dns-search home.lan auto br0 iface br0 inet static address 192.168.7.2/24 gateway 192.168.7.1 bridge_ports eno1 bridge_stp on bridge_fd 2 bridge_hello 2 bridge_maxage 20 dns-nameservers 127.0.0.1 192.168.7.1 8.8.8.8 dns-search home.lan Все, что закомментировано — старые настройки сети; br0 — название интерфейса создаваемого моста; eno1 — сетевой интерфейс, через который будет работать мост. Если вы получаете адрес динамически через DHCP, то конфигурация сократится до такой: source /etc/network/interfaces.d/* auto lo iface lo inet loopback auto br0 iface br0 inet dhcp bridge_ports eno1 bridge_stp on bridge_fd 2 bridge_hello 2 bridge_maxage 20 Внимательно проверяем конфигурацию и перезапускаем службу сети: sudo systemctl restart networking Начиная с релиза Ubuntu 17.10, для управления конфигурацией сети по умолчанию используется утилита Netplan, которая добавляет новый уровень абстракции при настройке сетевых интерфейсов. Конфигурация сети хранится в файлах формата YAML. Предоставляется эта информация бэкендам (network renderers), таким как NetworkManager или systemd-networkd. Файлы конфигурации Netplan хранятся в папке /etc/netplan. Для настройки сети открываем в редакторе файл 01-netcfg.yaml vim /etc/netplan/01-netcfg.yaml и приводим его к такому виду: network: version: 2 renderer: networkd ethernets: ens3: dhcp4: false dhcp6: false bridges: br0: dhcp4: false dhcp6: false interfaces: addresses: gateway4: 192.168.7.1 nameservers: search: addresses: parameters: stp: true forward-delay: 2 hello-time: 2 max-age: 20 Ну а при использовании динамической адресации файл конфигурации будет выглядеть так: network: version: 2 renderer: networkd ethernets: ens3: dhcp4: false dhcp6: false bridges: br0: dhcp4: true dhcp6: true interfaces: parameters: stp: true forward-delay: 2 hello-time: 2 max-age: 20 В файлах конфигурации указываем свои адреса, имена интерфейсов и доменов и после тщательной проверки применяем сетевые настройки: sudo netplan apply Виртульные сети (NAT forwarding) Каждая стандартная установка libvirt обеспечивает подключение виртуальных машин на основе NAT из коробки. Это так называемая виртуальная сеть по умолчанию. Вы можете проверить, что она доступна таким образом: sudo virsh net-list --all Name State Autostart Persistent ---------------------------------------------------------- default active yes yes Для того, чтобы виртуальные машины с сетевым интерфейсом NAT могли выходить в интернет необходимо настроить перенаправление сетевого трафика. Для этого надо убрать комментарий строки #net.ipv4.ip_forward=1 в файле /etc/sysctl.d/99-sysctl.conf и сохранить настройки: sudo vim /etc/sysctl.d/99-sysctl.conf sudo sysctl -p /etc/sysctl.d/99-sysctl.conf Создание виртуальной машины Для создания виртуальной машины нам понадобятся две утилиты: osinfo-query — для получения списка доступных для установки вариантов операционных систем и virt-install — непосредственно для самой установки. Итак, создадим нашу первую виртуальную виртуальную машину с ОС Ubuntu 16.04, 1024MiB ОЗУ, 1 процессором, сетью через мост и 12GiB жестким диском. sudo virt-install \ --name ubuntu1604s \ --os-type=linux --os-variant=ubuntu16.04 \ --vcpus=1 \ --ram 1024 \ --network network=bridge:br0 \ --disk path=/kvm/hdd/ubuntu1604s.qcow2,format=qcow2,size=12,bus=virtio \ --cdrom=/kvm/iso/ubuntu-16.04.6-server-amd64.iso \ --graphics vnc,listen=0.0.0.0 --noautoconsole \ --hvm --virt-type=kvm Обратите внимание на параметр --os-variant. Он указывает гипервизору под какую именно ОС следует адаптировать настройки. Список доступных вариантов можно получить, выполнив команду: osinfo-query os Подробнее с параметрами virt-install вы можете ознакомиться на страницах руководства, а я приведу команду создания ВМ c сетью через NAT: sudo virt-install \ --name ubuntu1604s \ --os-type=linux --os-variant=ubuntu16.04 \ --autostart \ --vcpus=2 --cpu host --check-cpu \ --ram 2048 \ --network network=default,model=virtio \ --disk path=/kvm/vhdd/ubuntu1604s.qcow2,format=qcow2,size=12,bus=virtio \ --cdrom=/kvm/iso/ubuntu-16.04.6-server-amd64.iso \ --graphics vnc,listen=0.0.0.0,password=vncpwd --noautoconsole \ --hvm --virt-type=kvm После запуска установки в консоли сервера вы увидите текст похожий на этот: Domain installation still in progress. Waiting for installation to complete. Значит все нормально и для продолжения установки ОС в виртуальной машине нам нужно соединиться к ней по VNC. Чтобы узнать номер порта на котором он поднят для нашей ВМ откройте новую консоль или в текущей переведите задание в фоновый режим с помощью CTRL+Z, bg и выполните команду: sudo virsh dumpxml ubuntu1604s | grep graphics В моем случае это порт 5903: или выполнив команду sudo virsh vncdisplay ubuntu1604s вы получите примерно такой результат: :3 Это число нужно сложить с базовым портом 5900. Далее подключаемся с помощью клиента VNC (Remmina, TightVNC) к нашему серверу по полученному порту и устанавливаем Ubuntu 16.04 в нашей ВМ.

После успешного завершения установки в консоли вы увидите примерно следующее: Domain has shutdown. Continuing. Domain creation completed. Restarting guest. Управление виртуальной машиной Для управления гостевыми системами и гипервизором существует текстовая утилита virsh. Она использует libvirt API и служит альтернативой графическому менеджеру виртуальных машин virt-manager. Я коснусь только основных команд управления ВМ, так как описание всех возможностей утилиты — тема для отдельной статьи. Список всех доступных команд вы можете увидеть так: virsh help Описание параметров отдельной команды: virsh help command где command — это команда из списка, который мы получили выше. Для ��росмотра списка всех виртуальных машин используйте: sudo vish list --all Вот что она показала у меня: Id Name State ---------------------------------------------------- 1 ubuntu16 running 3 centos8 running 6 ubuntu18 running 10 ubuntu1604server running - win10 shut off - win2k16 shut off - win2k16-2 shut off - win7 shut off Если же вам нужны только работающие в данный момент виртуалки, то введите: sudo virsh list Для запуска виртуальной машины выполните в консоли: sudo virsh start domain где domain — имя виртуальной машины из списка, который мы получили выше. Для выключения: sudo virsh shutdown domain И для ее перезагрузки: sudo virsh reboot domain Редактирование конфигурации ВМ: sudo virsh edit domain Read the full article

tagged by @elizabethsyson

Nickname: Muggle is my nickname, but when I went by Muggle in person for more than a month at a time, it naturally got abbreviated, usually to Mugz

Zodiac: Aquarius

Last movie I saw: into the spiderverse (same answer as last time. I don't watch that many movies tbh except around Christmas. unless YouTube counts in which case... music of some sort? idk links for the next answer)

Favorite musician: changes by the day. I've kinda been in an acapella and/or folk music mood recently so the Maccabeats and Peter Hollens are in my YouTube and Spotify history a lot recently. also I'm eternally in awe of Forte Handbell Quartet (eta a longer video; i recommend skipping to the techno piece or the Jurassic Park theme)

Last thing I googled: "vine why are you buying clothes at the soup store" (my wife hasn't seen it; also i can't find the vine because apparently it's a much bigger meme than I realized). before that it was "chgrp not root" because work and group permissions are useful when they work

Song stuck in my head: well for most of the day when I haven't been actively listening to something, it's been the Pokemon RSE route-walking music. (but that somehow happens frequently when I'm in the no-music-no-internet room at work, as I was for most of the day, and I don't know how I accidentally trained my brain to make that connection). right now, surprisingly, I don't have any background music playing in my head. I think it's because the humidifier provides just enough white noise that my brain doesn't feel the need to provide its own

Other blogs: my main is @muggle-the-hat and I'm a mod on @why-do-neurotypicals but we've gotten one ask ever so that blog has been dormant for a while. I have a bunch of other sideblogs, but they're all small and I use different screen names on each of them (enby life: no idea which name suits me best so I may as well try them out) so i feel like it would just confuse things to link them.

Following: blogs matching all the themes of my sideblogs, (including this one, which is writeblr), korean langblr, jumblr, assorted fandom blogs, authors of my more favorite fanfictions (some overlap with other categories), and irl friends and acquaintances (including one fandom blog turned irl friend)

Do I get asks: on my main if at all, which isn't really surprising because i have hundreds of followers there and maybe 60 followers combined among the rest. but I get asks far less often than I reblog ask memes so... I'm always happy to get more. I do get tagged in ask games more on this one, but writeblr is actually vaguely organized about tag lists so that makes sense. also I used to get tagged a bunch on my main and I rarely could find the posts again to follow up when I had time to answer.

What I’m Wearing: pajamas. staying warm and cozy

Lucky number: I don't remember what I said last time, but I like a lot of numbers. 64 is a good number. recently I've been debugging software in which 0x3E is my lucky status number and 0x0E taunts me. (um, decimal 62 and 14). Also my other favorite number i can't share until it's no longer the combination to the lock to the Secret Room. (or realistically never because opsec and i shouldn't make public the types of parents we use for that combination lock), honestly I aim to be like.... ah, I'm sure the anecdote involves G.H. Hardy but i don't remember on which side. anyway one mathematician remarked to another about how the id number of the taxi he rode in was sadly uninteresting, and the one I aspire to be like, argued "what are you talking about, this number is interesting because ______" and I'd like to be able to do that for any arbitrary number thrown at me. (hi yes math is good, history is hard, math history is interesting yet i still forget the people even if i remember the math. except when things are named after people, but that tends to be, like, Euler and LaGrange and other people who did lots of cool science things so i remember the methods and the names of the methods separately which never helps)

Amount of sleep: ....depression both screws with my sleep schedule and means I always feel like I need more sleep except when I wake up at 5pm and feel like I've wasted the day. so yeah. I can never get enough sleep

Favorite food: yes (why do I have to pick a favorite?) uh, chocolate in most forms, many other sweet things, red meats (especially if served with potatoes), curry (especially if it has "too much" ginger), fresh-baked bread, chai the way my favorite local Indian restaurant makes it (spicier with just a little bit of sweet, which is the opposite of what i can get from the mocha machine at work which is wayyy sweet with a hint of spice but that inferior chai is still superior to coffee so i drink too much of it). also vegetables which I really don't eat enough of: sauteed zucchini and onions, roasted broccoli

Dream trip: dreaming requires creativity and tbh I funnel that mostly into my writing instead. I wouldn't mind going back to Korea for another visit though

Dream job: my current job is pretty good when I feel productive and when my debugging tools actually produce data maybe??? (they were not being helpful today. but i still mostly like my job.) dream job is probably this but with seniority and confidence and double the salary (while living in a similar area of the country; I wouldn't want to double my salary by moving to work for Google in California and having less available after rent than I do now)

Describe yourself as aesthetic things:

the smell of old books

the first glow of sunrise (the sunrise painting the mountains pink and gold)

a rainbow in the spray from a waterfall

the flicker of distant lightning (watching a thunderstorm fade into the distance)

how about a combination answer: when we got our new handbell music this season, we only looked at half the pieces our first rehearsal and afterwards I tried to look up one of the pieces we hadn't gotten to on YouTube because it's got a weird time signature and I wanted to get a feel for how fast it would go and how strict the counting is...... except it turns out we're the first group to ever play the piece. it was commissioned recently but seeing my conductor's name on the page didn't tell me how new it was because he's super prolific. (the fact that it was on printer paper without the publisher's graphics should have been a giveaway but it's only the second time I've been among the first to play one of his pieces so I think I can be excused for not realizing)

Languages: mostly just English, but I took Spanish for years, so I can hold simple conversations in it. I can almost read sound out Hebrew fast enough to keep up in services, and I know some random Hebrew vocab but comparatively no grammar. and I took Korean in college, enough that I can recognize sentence structure but I can really only speak tourist-Korean, though I can sound anything out (if it's typed. handwriting is hit or miss.) in both Hebrew and Korean (and Spanish tbh but i don't often listen to Spanish music) I'm very proud when I can separate the words enough, listening to a song, to translate them without looking up the lyrics. also I tried to learn Japanese from Duolingo when it was new, but I still hadn't gotten the kana straight when it started progressing to kanji so that was a rough time and I went back to Hebrew.

tbh I "dabble" in "language learning" which really means I start a million courses on Duo and stick with none of them. with the notable exception of French, which I acknowledge is super common and probably a good idea to learn but the spelling and pronunciation seem so arbitrary I'm scared to look close enough to learn it properly, and I've never particularly considered starting the Duolingo course for French

I think I lost a few questions, because that's only 18 answers. whoops.

um... who to tag

@abluescarfonwaston if school hasn't drowned you in work yet and @copperscales I'm interested in both of your choices for lucky numbers especially.

... wow I'm blanking on other mutuals I haven't tagged recently. as usual lmk if you'd like to be edited in, or just answer the questions and tag me back, that's great too.
