Check the ownership of /dev/kvm ls -al /dev/kvm Check which users are in the kvm group grep kvm /etc/group Output from the above command kvm:x:some_number: If there is nothing rightwards of the final :, there are no users in the kvm group. To add the user your_name to the kvm group sudo adduser your_name kvm which adds the user to the group, and check once again with grep kvm /etc/group. A restart may be required for the permissions to take effect.
