Installing qemu on linux mint

From time to time I want to run a virtual machine on my computer, a sandbox containing another operating system with some programs running in total isolation. Under Linux my answer for this need is a set of three components:

KVM – a virtualization module in the Linux kernel that allows the kernel to function as a hypervisor. (Wikipedia)
QEMU – a machine emulator and virtualizer that can perform hardware virtualization. It can cooperate with KVM to run virtual machines at near-native speed (Wikipedia)
Virtual Machine Manager – a nice GUI to use above things as simply as possible.

Problem

How prepare all above components on a fresh installation of Linux Mint 20.1?

Solution

This solution is based on the article “Install KVM Virtualization on Linux Mint 20” with my additions.

First execute following commands:

sudo apt-get install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils virt-manager sudo adduser $USER libvirt sudo adduser $USER kvm sudo adduser $USER libvirt-qemu

Here the above-mentioned article claimed everything is ready and working. But it wasn’t in my case. So just restart Linux now. Then proceed with verification steps:

systemctl status libvirtd.service

The output should start with following lines:

● libvirtd.service - Virtualization daemon Loaded: loaded (/lib/systemd/system/libvirtd.service; enabled; vendor preset: enabled) Active: active (running) since Wed 2021-02-03 22:54:41 CET; 31s ago

Then start Virtual Machine Manager. It should show that it is connected to KVM/QEMU. It should look like this:

Hello To share the libraries such as copy/paste, devices, folders, etc, from the virtualized machine wath the main system, what else should I do? Greetings

This works except all I had to do was “sudo apt install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils virt-manager”, reboot, and it just worked. @ Dero ; I had the same issue and while I suspect it’s possible to get other methods working I just setup a basic Samba share on the host Mint 20 machine and then from the Windows (Win10) virtual machine I just did the following (without the “) on the section you can type stuff in bottom left area of screen… “\\192.168.1.100\” (or whatever is the IP of the machine running Samba) and it showed the folder name I was sharing and I select it and it just worked (since I did not setup any username/password stuff anyone on my network can access that share straight up). because trying to setup a more standard way of sharing seems more difficult on this QEMU/KVM than in VirtualBox.

You don’t have to reboot. Just log out of the GUI and log back in and your user’s groups will be refreshed and you’re GTG.

Installing qemu on linux mint

Как Linux-энтузиаст, я тестирую немало приложений и дистрибутивов практически ежедневно. Наряду с известным многим Oracle Virtualbox, есть еще немало интересных продуктов в сфере виртуализации, таких как Vmware, openVZ, KVM, Proxmox и т.д.. Сегодня мы будем говорить про QEMU.

Re: Установка и настройка QEMU в Linux Mint (Ubuntu) 1. Введение

QEMU — нативный и открытый машинный эмулятор и виртуализатор. Этот свободный интсрумент с открытым исходным кодом позволяет пользователям создавать и управлять виртуальными машинами внутри операционной системы(т.н. хост-системы). Аппаратные ресурсы хост-системы,такие как дисковое пространство, RAM, ЦПУ, будут отделены и поделены между гостевыми операционными системами(виртуальными машинами).

Когда используется как машинный эмулятор, QEMU сможет запускать ОС и программы созданные для какой либо платформы(например на ARM платах) на вашем ПК. Используя динамическую трансляцию, это происходит с хорошей производительностью.

Использая режим виртуализатора, QEMU получает схожую с нативной производительность путем испольнения кода напрямую на ЦПУ хост-ситемы. QEMU поддерживат виртуализацию с помощью гипервизора Xen или используя KVM модули ядра Linux. Для KVM, QEMU может виртуализировать такие платформы как x86, PowerPC и S390 в качестве гостевых.

В QEMU есть два режима работы:

Полная эмуляция системы: в этом режиме, QEMU эмулирует гостевую систему полностью (для примера PC), включая процессор и разнообразные периферийные устройства. Этот режим может использоваться для запуска других операционных систем или дебага системного кода.

Пользовательский режим эмуляции (только для Linux хостов): В этом режиме, QEMU Может запускать Linux-процессы собранные для одного CPU, на другом. Для примра это может быть облегченная кросс-компиляция.

QEMU Отлично работает с следующими аппаратными платформами:

PC (x86 or x86_64 processor) ;
ISA PC (old style PC without PCI bus) ;
PREP (PowerPC processor) ;
G3 Beige PowerMac (PowerPC processor) ;

How to Install KVM on Linux Mint 21?

“Today, we will learn how to install KVM on Linux Mint 21 using the command line. KVM is a complete virtualization solution for Linux on x86 hardware. Using this, we can easily create Virtual Machines just like we do in VMware or VirtualBox. The best part about KVM is that it is open source and more efficient than its rival virtualization solutions.”

We have used basic Linux commands implemented on Linux Mint’s Terminal to install KVM. Let’s see how it is done!

Guide

Following are the steps involved in installing KVM on Linux Mint 21:

Step 1: Update and Upgrade Linux Mint

Before installing KVM, it is recommended to update your system and upgrade it. The following commands will help us in updating and upgrading our Linux Mint machine:

Step 2: Check System Compatibility With KVM

Next, we need to check whether KVM is compatible with our system or not. If it is not compatible, then we’ll keep running into errors.

If you get an output above 0, that means KVM is compatible with your system and can be easily installed. In our case, we got an 8. This means we can install KVM on our system.

Step 3: Install KVM

Now that we have made sure that KVM can be installed, let’s install it by executing this command:

Step 4: Add Your User to the KVM and Libvirt Group

It is now time to add your user to KVM and libvirt group to set up KVM so that you don’t run into any permissions-related errors. Add the user to the KVM group like this::

Add the user to the libvirt group with this command:

How to Create a Virtual Machine(VM) in KVM?

Now that we have installed KVM let’s see how we can create a VM on it. First, download the iso you want to create a VM of. We have downloaded an iso for Ubuntu 20.04.

Now open Virtual Machine Manager on your machine. This is how the interface will appear:

Click on File; you will see a list of options to choose from. Now click on New Virtual Machine:

This window will open with a list of options to choose from for your VM:

Please select the first option, as it allows you to create a VM using an ISO image. Once selected, click Forward.

Now select the iso that you downloaded, as shown below:

After that, allot memory and CPU utilization for the VM like this:

Next, allot storage to the VM:

Now, give the VM a name. For example, if the VM is Ubuntu, you can name it Ubuntu, followed by its version.

These are all the settings that were required. Click on Finish to finish the VM setup. The VM creation process will begin after that.

Once the VM is created, a new window will open for OS installation. You can then install the OS easily.

Conclusion

In today’s guide, we saw in detail how to install KVM on Linux Mint 21. We began by updating and upgrading the system. Then we verified KVM compatibility. Afterward, we installed KVM on our machine. In the end, we also saw how to create a Virtual Machine on KVM.
