ProbeKVM: This user doesn't have permissions to use KVM (/dev/kvm). The KVM line in /etc/group is: [LINE_NOT_FOUND] code example
Example 1: where is /dev/kvm
This is how I got it to work in Ubuntu 18.04
1. Install qemu-kvm
$sudo apt install qemu-kvm
2. Add your user to kvm group using:
$sudo adduser <Replace with username> kvm
3.If still showing permission denied:
$ sudo chown <Replace with username> /dev/kvm
This works!
Example 2: grant current user access to /dev/kvm
To check the ownership of /dev/kvm use
ls -al /dev/kvm
The user was root, the group kvm. To check which users are in the kvm group, use
grep kvm /etc/group
This returned
kvm:x:some_number:
on my system: as there is nothing rightwards of the final :, there are no users in the kvm group.
To add your user to the kvm group, you could use
sudo adduser $USER kvm
