Title:
  70-udev-acl.rules needs to put g+rw on /dev/kvm

Status in “udev” package in Ubuntu:
  Confirmed

Bug description:
  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
