Description of problem:

When running guestfish, I always get this message:

libguestfs: warning: current user is not a member of the KVM group (group ID 118). This user cannot access /dev/kvm, so libguestfs may run very slowly. It is recommended that you 'chmod 0666 /dev/kvm' or add the current user to the KVM group (you might need to log out and log in again).

On a modern desktop, permissions are setup by logind:

# file: dev/kvm
# owner: root
# group: kvm
user::rw-
user:bernat:rw-
group::rw-
mask::rw-
other::---

I think libguestfs should just try to open /dev/kvm (RW) and close it. If this succeeds, this means that the permissions are correct.

Version-Release number of selected component (if applicable):

1.26.7
