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, Install the needed Tool: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. Installing KVM
Now you are Ready to Install KVM on Elementary OS System
sudo apt update
sudo apt install qemu qemu-system qemu-kvm libvirt-bin ubuntu-vm-builder bridge-utils
Following Elementary OS Documentation about KVM related Packages:
- libvirt-bin provides libvirtd which you need to administer qemu and kvm instances using libvirt
- qemu & qemu-kvm (kvm in Karmic and earlier) are the backend
- ubuntu-vm-builder powerful command line tool for building virtual machines
- bridge-utils provides a bridge from your network to the virtual machines
-
4. Adding User to Group
Next Add User to libvirt Group
First, you need to Make the Group:sudo addgroup libvirtd
And then Add User with:
sudo adduser `id -un` libvirtd
This because only the Users of this Group can Run Virtual Machines.
Then Relogin to Enable this Setup! -
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.

6. Starting Libvirt Daemon
Again to Start Libvirtd Daemon.
sudo service libvirtd start
And to Enable it on Boot:
sudo update-rc.d libvirtd enable
