KVM means a virtual machine based on the kernel. This software allows users to run multiple virtual machines with different operating systems, eliminating the need to follow more traditional methods of using Virtualbox. The CWM is free, open source and has been continuously improved and developed over the past ten years.

This article shows you how to install and configure KVM on your ArchLinux system.

Part 1: KVM installation

The KVM installation procedure is somewhat complicated, as it first has to be checked whether the system meets the requirements.

Step 1: Virtualization support Audit

To check if virtualization is enabled on your PC, run the following command:

LC_ALL=C lscpu | grep Virtualization

Hardware specifications for KVM – VT-x for Intel processors and AMD-V for AMD processors So if your system has the necessary hardware to create virtual machines, you will see the following in the displayed text

Virtualization: Virtualization VT-x
or
: AMD-V

If these are not displayed, it means that your system cannot support virtualization or that it has been disabled by the developers on the machine. In this case, you can enable virtualization when restarting the system and logging into the BIOS.

Step 2: Search for kernel module

To check if your system has a kernel module to run KVM, type the following command:

$ zgrep CONFIG_KVM /proc/config.gz

If you are using an AMD processor, you should see CONFIG_KVM_AMD (or CONFIG_KVM_INTEL if you are using intel), followed by =y or =m, then you can go.

Step 3: Installation of a KVM for ArchLinux

Start up the terminal and execute the following code for the direct installation of the KVM :

sudo pacman -S virt-manager qemu vde2 ebtables dnsmasq bridge-utils openbsd-netcat

This should enable you to install the KVM in your system.

Step 4: Activating and starting the KVM

Enter the following command to activate the KVM:

Activate sudo systemctl libvirtd.service

Then enter the following:

$ execute sudo systemctl libvirtd.service

Then go to /applications and execute the VM manager.

Part 2: KVM configuration

To continue using KVM with the standard Linux account, you can do this by modifying the libvirtd.conf file. To access the folder, enter the following data:

$ ship pacman -S vim
$ ship vim /etc/libvirt/libvirtd.conf

Between lines 80-90 there must be a line about term on unix_sock_group. They’re trading him in for Libworth.

# unix_sock_group = libvirt

Go to the lines between 100-110 and change unix_sock_rw_perms to = 0770.

# unix_sock_rw_perms = 0770

Then release the following code to add your default Linux account to libvirt.

Sudo usermod -a -G libvirt $(whoami)

Restart the libvirt service to make changes. Release the following code:

$ sudo systemctl restart libvirtd.service

You can now use your Linux account to use KVM.

To create virtual machines in a virtual machine, you can enable nested virtualization by typing:

$ sudo modprobe -r kvm_intel
$ sudo modprobe kvm_intel nested=1

To apply these changes, enter

$ kvm-intel echo options connected=1 | sudo tee /etc/modprobe.d/kvm-intel.conf

Conclusion

This tutorial explains how to install and configure KVM on ArchLinux systems. If you have followed the instructions correctly, you should be able to configure the KVM in your system and be ready to boot virtual machines.
