As per 1367702, this is not using LXC (which u used in your attempt). This is running bare-metal, no container, no hypervisor. Each VM below is started from OpenStack nova-compute (this node is a compute-only node).

========================
Impact: libvirt hangs
Fix: mutex libvirt's access to cgmanager
Test case: see script in #14
Regression potential: if this is done wrongly, it could cause a deadlock. No non-cgmanager codepaths are affected.
========================
reference bug 1367702. As per request, opening new ticket w/ instructions to reproduce.
This is on 14.10 server, libvirt-bin 1.2.8-0ubuntu11.1
As per 1367702, this is not using LXC (which u used in your attempt). This is running bare-metal, no container, no hypervisor. Each VM below is started from OpenStack nova-compute (this node is a compute-only node).

2014-11-27 22:38:18.385+0000: 26441: error : cgm_dbus_connect:76 : cgmanager: Error pinging manager: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
process 26422: The last reference on a connection was dropped without closing the connection. This is a bug in an application. See dbus_connection_unref() documentation for details.
Most likely, the application was supposed to call dbus_connection_close(), since this is a private connection.

Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
cgm ping returns true, so cgmanager is presumably ok.
sometimes when doing the libvirtd -v manually it does a segfault instead of an assert.
sometimes the assertion is different:
(null):cgmanager-client.c:1015: Assertion failed in cgmanager_get_pid_cgroup_sync: proxy != NULL
Segmentation fault (core dumped)
or
(null):alloc.c:315: Assertion failed in nih_free: ptr != NULL
(null):alloc.c:315: Assertion failed in nih_free: ptr != NULL
Segmentation fault (core dumped)
