В этой статье я расскажу, как можно с минимальными издержками установить гостевую ОС Windows на гипервизоре QEMU с помощью графического интерфейса virt-manager. Мы нанесем на карту все подводные камни и рифы, а жучков аккуратно посадим в банку.

Подготовка

Самый первый шаг — настройка параметров ядра. Обязательна поддержка KVM и vhost-net, желательна поддержка туннельных интерфейсов^[1] и сетевого моста^[2]. Полный список на Gentoo вики-странице QEMU.

Подготовьте дисковое пространство. Я выделил 70 GiB, и Windows 8.1 за пару месяцев использовала почти 50 GiB так, что для обновления до 10-й версии места на диске не хватило.

Далее, нам понадобится набор редхатовских драйверов virtio-win. Если у вас установлен RedHat, достаточно запустить

[root@server ~]# yum install virtio-win

и образ iso будет записан в каталог /usr/share/virtio-win/. Также можно его скачать с репозитариев Fedora.
Убедитесь, что поддержка аппаратной виртуализация включена в BIOS/UEFI. Без этого KVM не будет активирован, а virt-manager выдаст вот такую ошибку.

В качестве проверки можно прочитать файл устройства.

(2:506)$ ll /dev/kvm
crw-rw----+ 1 root kvm 10, 232 ноя 9 02:29 /dev/kvm

Если файл не обнаружен, а опции ядра выставлены верно, значит дело в настройках BIOS/UEFI.
Устанавливаем нужные пакеты.

(5:519)$ sudo emerge -av qemu virt-manager

Для RedHat 7 достаточно установить только virt-manager, так как QEMU устанавливается по умолчанию.

[root@server ~]# yum install virt-manager

Дебианщикам надо установить пакет qemu.

root# aptitute install qemu

Можно теперь переходить к установке.

Запуск и инсталляция

Запускаем virt-manager и создаем новую виртуальную машину из локального хранилища.

Указываем путь к установочному iso образу Windows.

Далее, на 3-м и 4-м шаге будет выбор количества CPU, объем RAM и размер дискового пространства, после чего на 5-м шаге следует выбрать дополнительные конфигурации перед настройкой.

Картинка с сайта: habr.com

Окно дополнительных настроек нужно для того, чтобы выполнить финт ушами. Его смысл в том, чтобы добавить виртуальный флопарь с драйверами из набора virtio-win. Это даст возможность изменить тип жесткого диска: удалить диск с шиной IDE и добавить его же, но с шиной VirtIO. Подробно, в доках RedHat.

Картинка с сайта: habr.com

Прописываем драйвер /usr/share/virtio-win/virtio-win.vfd и добавляем виртуальный флоппи-диск. Затем переходим на вкладку [Шина] Диск № и проделываем финт с заменой шины диска: удаляем с IDE и добавляем с VirtIO.

Картинка с сайта: habr.com

Чуть не забыл сказать, для чего нужен этот фокус. Специалисты утверждают, что с шиной VirtIO, производительность диска ощутимо выше.

В принципе, уже можно начинать инсталляцию, но мы забыли добавить CD-ROM с драйверами virtio-win, а они нам пригодятся, когда диспетчер устройств засверкает желтыми иконками вопросительного знака.

Картинка с сайта: habr.com

Ну вот теперь можно начать установку.

Ну хорошо, начали мы установку. А что, если установщик Windows попросит сменить диск? Мне из-за этого пришлось пару раз прервать и начать всю карусель заново, но с вами такого уже не случится.

(qemu) change ide1-cd0 /tmp/windows_8.1_x64_disk2.iso

Драйвера и доводка

По окончанию процесса установки диспетчер устройств недосчитается некоторых драйверов. Предположительно, это могут быть:

Ethernet Controller
PCI Simple Communication Controller
SCSI Controller

Нужно скормить им драйвера из набора virtio-win, что подключены через IDE CD-ROM в предыдущем разделе.

Картинка с сайта: habr.com

Делается это стандартно: правой кнопкой на желтый знак вопроса, обновить драйвера, путь к файлам.

Вот весь список, а это соседняя страница RedHat доков, где установка драйверов показана подробнее.

• Balloon, the balloon driver, affects the PCI standard RAM Controller in the System devices group.
• vioserial, the serial driver, affects the PCI Simple Communication Controller in the System devices group.
• NetKVM, the network driver, affects the Network adapters group. This driver is only available if a virtio NIC is configured. Configurable parameters for this driver are documented in Appendix E, NetKVM Driver Parameters.
• viostor, the block driver, affects the Disk drives group. This driver is only available if a virtio disk is configured.

Оборудование

Тут постепенно начинается область безграничных возможностей и 101 способов сделать по-своему, поэтому я покажу, как это работает у меня, а вы можете настроить более точно под свои нужды.

Картинка с сайта: habr.com

У меня выбран дисплей Сервер Spice и звуковое устройство ich6. Нет, конечно, если у вас уйма времени и желание во всем разобраться до самых тонкостей — дерзайте и пробуйте альтернативные подходы, но у меня звук взлетел, вернее завибрировал, только с такими настройками. Во второй части, посвященной прогулке по граблям и отлову багов, я расскажу об этом подробнее. В закладке видео я выставил QXL, ибо с этой опцией, благодаря волшебному драйверу, мне удалось добиться нормального разрешения экрана.

Подключаться к ВМ можно разнообразно.

1. Через графический интерфейс virt-manager
2. Выбрать дисплей VNC-сервер и подключаться через vnc-клиента
3. Установить Spice-клиента и подключаться через него
4. К Windows можно подключиться через rdp, если включен терминальный сервер

У меня вариант 3, для Gentoo это программа spice-gtk

     Описание:              Set of GObject and Gtk objects for connecting to Spice servers and a client GUI

Сеть

Сеть для ВМ можно настроить по-разному, на Хабре умельцы уже об этом писали. Я перепробовал несколько способов, и в конце простота опять взяла вверх. Сама ВМ запускается из под рута^[3], но графический интерфейс spice-gtk — из под обычного непривилегированного пользователя. Это позволяет решить дилемму: для сетевых опций нужны права рута, а для звукового демона pulseaudio, рут запрещен. Я пробовал навешать все права на обычного пользователя, но ничего не получалось, то pulse не пульсирует, то сеть не создается, там много а тут мало. В итоге решил так и доволен. Буду рад, если в комментариях будет найден лучший способ.

Такой простой выбор сетевых опций дает результат превосходящий ожидания. Создаются 3 дополнительных сетевых интерфейса: virbr0, virbr0-nic, vnet0.

$ ip addr
...
4: virbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether 52:54:00:cc:2a:1e brd ff:ff:ff:ff:ff:ff

    inet6 fe80::fc54:ff:fefb:5045/64 scope link 
       valid_lft forever preferred_lft forever

В iptables создается свод правил, вот основные:

$ sudo iptables -L
...
Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Повторяю, все это libvirtd создает сам, ничего для этого делать не надо. В результате имеем нормальный роутинг между хостом и ВМ, можно обмениваться файлами по ssh / scp. Можно пойти дальше и создать шару на Windows, а на Linux хосте настроить samba, но мне это показалось избыточным.

В завершение

Трудно рассказать в одной статье обо всех аспектах Windows + QEMU/KVM, поэтому завершим в следующей. А там будет самый смак, командный интерфейс, разрешение экрана максимум 1024×768, Сцилла pulseaudio и Харибда сети, команда virsh и настройка ВМ из конфиг файла, фейл с tpm, двоичный синтаксис устройств и прочие тихие радости.

Prerequisites

Before you start, ensure you have the following:

• A Linux host operating system (Ubuntu, CentOS, Fedora, etc.)

• At least 4 GB of RAM (8 GB recommended) and sufficient disk space (at least 20 GB for the Windows VM)

• Administrative access to install packages and configure settings

• Basic knowledge of command-line operations

Installing KVM and QEMU

Step 1: Check if your CPU supports virtualization

Run the following command to check if your CPU supports virtualization:

egrep -c '(vmx|svm)' /proc/cpuinfo

A value greater than 0 indicates your CPU can support KVM.

Step 2: Install KVM and QEMU

For Ubuntu, use these commands:

sudo apt update
sudo apt install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils virt-manager

For CentOS, run:

sudo yum install qemu-kvm libvirt libvirt-python libguestfs-tools virt-manager

After the installation, confirm that the KVM modules are loaded:

Step 3: Add your user to the KVM group

Make sure your user account has the necessary permissions:

sudo usermod -aG kvm $USER

Log out and back in for the changes to take effect.

Configuring KVM

Enable the libvirt service to allow managing VMs seamlessly:

sudo systemctl enable --now libvirtd

Check the status of the libvirt service:

sudo systemctl status libvirtd

Downloading Windows 10 ISO

1. Visit the official Microsoft website.

2. Download the Windows 10 disk image (ISO file).

3. Make sure to save the ISO in a directory accessible to your virtual machine.

Creating a Windows 10 VM

Step 1: Create a disk image for the VM

Run the following command to create a virtual disk image for your Windows 10 installation:

qemu-img create -f qcow2 ~/win10.img 50G

This command creates a 50 GB disk image named win10.img in your home directory.

Step 2: Use virt-install to create the VM

You can launch a new VM using virt-install, specifying the appropriate parameters:

virt-install \
    --name win10 \
    --ram 4096 \
    --disk path=~/win10.img,size=50 \
    --vcpus 2 \
    --os-type windows \
    --os-variant win10 \
    --network network=default \
    --graphics vnc \
    --cdrom /path/to/windows10.iso

Explanation of parameters:

• --name: Name of the VM (Windows 10).

• --ram: Amount of RAM assigned to the VM.

• --disk: Path and size of the virtual disk.

• --vcpus: Number of virtual CPUs to allocate.

• --os-type: Operating system type.

• --os-variant: Optimization specifics for the OS version.

• --network: Networking mode; typically, the default network.

• --graphics: Graphics display type (VNC in this example).

• --cdrom: Path to the Windows 10 ISO.

Step 3: Access the VM

Once the VM has been created, access it using a VNC viewer, or use virt-manager for a graphical interface:

Select your VM and open the console to start the installation process.

Installing Windows 10 on the VM

Follow the on-screen instructions once the Windows 10 installer loads:

1. Choose the language, time, and keyboard preferences.

2. Select “Install Now.”

3. Enter the product key (if required) or select “I don’t have a product key”.

4. Choose the “Custom: Install Windows only (advanced)” option.

5. Select the virtual disk (unallocated space) for installation.

After the installation completes, you will need to go through Windows setup (user accounts, privacy settings, etc.).

Optimizing Your Windows 10 VM

After installing Windows 10, optimizing the performance of your VM is crucial. Here are some tips:

• Install VirtIO Drivers: For better disk and network performance, install the VirtIO drivers. Download the drivers from the Fedora Project site and load them during Windows setup.

• Adjust Resource Allocation: Use virt-manager to fine-tune the RAM and CPU allocation based on your use-case.

• Disable Unnecessary Services: Inside Windows, you can disable services that are not needed for your specific tasks.

Common Troubleshooting Tips

• Boot Issues: If the VM fails to boot, double-check that the ISO is correctly attached to the VM and verify the disk settings.

• Network Issues: Ensure that your network settings in virt-manager or when using virt-install correctly link to an active network bridge.

• No VNC Connection: If you can’t connect via VNC, ensure that your VNC viewer is correctly configured and the firewall rules on the host allow VNC connections.

Conclusion

Setting up a KVM/QEMU Windows 10 VM can greatly enhance your productivity by allowing you to run Windows applications seamlessly on a Linux host. By following the steps outlined above, you will have a fully functional Windows 10 environment optimized for performance.

If you encounter issues during the setup or have specific questions, the virtualization community is robust and finding help online is just a search away. Happy virtualizing!

Do you want to use QEMU for Windows? This post from MiniTool shows you how to download and install the QEMU software on Windows. It also shows you how to use QEMU on Windows to create an Ubuntu VM.

What Is QEMU

QEMU, short for Quick Emulator, is a free open-source hosted virtual machine manager that can execute hardware virtualization. With the help of KVM (Kernel-based Virtual Machine), QEMU can offer fast running speed. Therefore, it develops fast and is going to replace VirtualBox and VMware on Linux.

However, on Windows, the advantages of QEMU are not significant, because the KVM technology is not applicable on the Windows host machine. In addition, the quickgui is also not available to Windows. But QEMU develops fast and many people still want to use this VM software on Windows.

QEMU for Windows Download and Install

1. Download QEMU for Windows

To use QEMU for Windows, you should download and install it first. Please refer to the following QEMU download guide:

Step 1: Go to the official QEMU website (https://www.qemu.org). Click the Download button at the top section. You will go to the QEMU download page.

Step 2: Click the Windows tab to get the QEMU Windows version. Click 32-bit or 64-bit according to what OS you are running (for me, I click the 64-bit because my OS is 64-bit).

Картинка с сайта: www.minitool.com

Step 3: On the new page, click the .exe file to download it. This file is the installer file.

Картинка с сайта: www.minitool.com

2. Install QEMU for Windows

After the installer file is downloaded, you can double-click it to run directly. Before doing that, I recommend you to create a partition separately for it. For any virtual machine software, I will recommend you create a separate partition to store the software and the VM files so that you can manage them better.

To create a separate partition, you can use the shrink feature in the Windows Disk Management tool. But this tool can’t help you move the location of partitions, so I recommend you to use MiniTool Partition Wizard.

If the free space of one partition is not enough, you can move/resize another partition to get more unallocated space and then gather the unallocated space together to create one partition. Here is the guide:

MiniTool Partition Wizard FreeClick to Download100%Clean & Safe

Step 1: Launch MiniTool Partition Wizard and go to its main interface. Right-click a partition and choose Move/Resize.

Картинка с сайта: www.minitool.com

Step 2: Drag the two arrows on the two sides of the partition to shrink the partition, and then drag the block to move the location of the partition. Then, click the OK button. In this way, you can get unallocated space.

How to Use QEMU on Windows

After installing the QEMU Windows version, you may want to know how to use QEMU to create a virtual machine. Here are 2 ways and the 2^nd way is better.

Way 1. Create a Virtual Machine Using Commands

QEMU doesn’t come with a GUI. If you don’t install a GUI manually, you need to use commands to run QEMU. Here is the guide on how to use QEMU on Windows to create a VM via commands (taking Ubuntu as an example).

Step 1: Download the Ubuntu ISO file from the official website.

Step 2: Add QEMU path into Environment Variables.

• Open File Explorer, go to the QEMU installation location, and then copy the path (E:\qemu).
• Right-click This PC / Computer, choose Properties, and then click Advanced system settings.
• Under the Advanced tab, click Environment Variables.
• In the User variables box, double-click the Path variable, click New, and then paste the QEMU path.
• Click the OK button to save changes, and then click the OK button again to save and exit the Environment Variables

Step 3: Run Command Prompt as administrator and then execute the following commands.

• E: (this will open the e drive where QEMU is installed).
• cd \qemu (this will open the qemu folder).
• qemu-img create -f qcow2 ubuntu20.img 30G (this will create a virtual hard drive of 30GB).
• qemu-system-x86_64.exe -m 1G -smp 2 -boot order=dc -hda ubuntu20.img -cdrom “e:\ubuntu-20.04.3-desktop-amd64.iso” (this will run Ubuntu using CD/ROM).

Картинка с сайта: www.minitool.com

Step 4: Go through the Ubuntu installation process. Although there may be many bugs, I launch Ubuntu 20 successfully and then just need to complete the installation process.

Way 2. Create a Virtual Machine Using QtEmu

As you can see, creating a VM using QEMU via commands is a tough job. You need to search for various tutorials online. In addition, once errors occur, you may have no idea how to solve them. Therefore, I recommend you to use QtEmu, an open-source GUI for QEMU Windows.

How to use QEMU on Windows via QtEmu? Here is the guide:

Step 1: Download the Ubuntu ISO file and QtEmu. The QtEmu official website is https://qtemu.org and the QtEmu source is placed on https://gitlab.com/qtemu/gui. Go to the GitLab source page, scroll down to find the Downloads section, and click the first link to download the QtEmu installer.

Картинка с сайта: www.minitool.com

Step 2: Double-click the QtEmu installer file and go through the installation process. When you are asked to specify the installation location (where to create the QtEmu folder), please install the QtEmu under the QEMU folder. For me, I type: E:\qemu\QtEmu.

Картинка с сайта: www.minitool.com

Step 3: After QtEmu is installed, go to E:\qemu\QtEmu. Right-click the qtemu.exe file and choose Send to > Desktop (create shortcut). Then, create a folder named VMs under the E drive to store all VM files to be created.

Step 4: Double-click the QtEmu shortcut to launch this software. In the QEMU options window, please set QEMU binaries path to E:\qemu, set QEMU img path to E:\qemu, and set QEMU machines path to E:\VMs. Then, click the Finish button.

Картинка с сайта: www.minitool.com

Step 5: Click Machine > New Machine. Then, give a name to the new machine (Ubuntu20), choose OS type (GNU/Linux), choose OS version (Ubuntu), and then click Next.

Step 6: On the Filter page, if you don’t need to specify certain motherboard chipsets, you can click the Next button directly to skip this step.

Step 7: Select a correct CPU Type, and set CPU, Graphics, Audio, and Network parameters. If all is OK, click the Next button.
