[Bug 828061] Re: cgroup-bin prevents libvirt from starting

reducing priority because there is a workaround - using cgroup-lite.

The packages at
https://bugs.launchpad.net/ubuntu/+source/libcgroup/+bug/828061 are
fixing this problem for me.

At heart the problem was that the libvirt-cgred-wait job would, if cgred
was not already running, start it.  But it's not cgred that we're
waiting on.  Rather it is the pre-start for cgconfig which must finish.
So the new libvirt-cgconfig-wait job waits for cgconfig to be in state
'start'.  If it takes more than 2 minutes to start, then something is
wrong, with cgtroup-bin and libvirt can go ahead and start, since what
matters for libvirt is not that cgroup-bin be running, but rather that
it not reclassify libvirt while libvirt is running.
