[Bug 842845] Re: problems starting multiple lxc instances concurrently

[Clint Byrum]

This looks more like a problem with libvirt, as its an internal libvirt
error..

(nova.exception): TRACE: File "/usr/lib/pymodules/python2.7/nova/virt/libvirt/connection.py", line 1168, in get_info
(nova.exception): TRACE: (state, max_mem, mem, num_cpu, cpu_time) = virt_dom.info()
(nova.exception): TRACE: File "/usr/lib/python2.7/dist-packages/libvirt.py", line 1059, in info
(nova.exception): TRACE: if ret is None: raise libvirtError ('virDomainGetInfo() failed', dom=self)
(nova.exception): TRACE: libvirtError: internal error Unable to get cgroup for instance-00000006

Though it could be a logic problem in some assumptions nova makes about
libvirt "domains" that is only proved false with LXC.

Marking as also affects libvirt, setting both to importance of High.
While this only affects users of LXC, its intermittent which may signal
other problems that are harder to detect.


** Also affects: libvirt (Ubuntu)
