Comment 34 for bug 1057024

Root cause found: udev automatically loads kvm_intel even when qemu-kvm is not installed. The kvm group and udev file causing /dev/kvm to be chgrp'd to kvm and set its permissions are installed by qemu-kvm.

If it were only a question of permissions I'd say the udev package should be setting those. However it would also have to add the kvm group.

So the qemu-kvm postinst should set the permissions on /dev/kvm if that already exists.
