Virtual Device configuration Linux

Some times you have to perform a couple of adjustments to get a virtual device working properly

Run the following command

sudo apt-get install qemu-kvm libvirt-bin virtinst bridge-utils cpu-checker

Verify that your machine supports hardware acceleration

 kvm-ok

If you receive the following output you are OK if not sorry you are not able

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

Next add your user to use libvirtd and kvm

sudo adduser $USER libvirtd
sudo adduser $USER kvm

To check the ownership of /dev/kvm use

ls -al /dev/kvm

To check which users are in the kvm group, use

grep kvm /etc/group

This returned

kvm:x:some_number:
