[Bug 1057024] Re: kvm kernel module always loaded, without setting /dev/kvm permissions

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.
