When qemu-system gets installed, the newly installed udev rule causes /dev/kvm to gets chgrpd to kvm and its mode to get set to g+rw. However, because /dev/kvm was tagged with ACL previously, there is a group:: acl on /dev/kvm which does not get removed. Therefore /dev/kvm is g+rw in the file mode, but the acl denies group read/write access. After a reboot all is fine.

I have not seen a clean way to have udev remove that acl, and there is no reason for it. So please update the 70-udev-acl.rules file to set MODE=0660 on /dev/kvm
