How to Install KVM on MX Linux – Step-by-step

Installing

2. 2. Pre-Installation Checks

   Then Check if KVM Can be Installed
   With:

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

   If in Output > 0 then your Processor support Hardware Virtualization!
   (But on a PC you may have still to enable it on BIOS…)
   Now again, first Install needed Tool with:

   sudo apt install cpu-checker

   And then Verify it:

   kvm-ok

   If it’s Good you will see:

   INFO: /dev/kvm exists
   KVM acceleration can be used
   

   Finally, if the answer is negative you can still use KVM but only in a Slow mode…

3. 3. Installing KVM

   Now you are Ready to Install KVM on MX System

   sudo apt update

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

   Following MX Documentation about KVM related Packages:

   • libvirt-clients libvirt-daemon-system provides libvirtd which you need to administer qemu and kvm instances using libvirt
   • qemu-kvm is the backend

4. 4. Adding User to Group

   Next Add User to libvirt Group
   So to Add User run:

   sudo adduser $LOGNAME libvirt

   This because only the Users of this Group can Run Virtual Machines.

5. 5. Verifing KVM Installation

   Finally, Test Installation.

   Simply performing:

   virsh list --all

   And in the Output you should find:

    Id    Name                           State
   ----------------------------------------------------

   This because still no VMs has been made.
