Open Stack

Well i've checked the libvirt logs on both nodes and i found these two
lines:

2012-07-09 13:58:27.179+0000: 10227: warning : qemuDomainObjTaint:1134 :
> Domain id=2 name='instance-00000002'
> uuid=57aca8a6-d062-4a08-8d87-e4d11d259ac7 is tainted: high-privileges
> 2012-07-09 13:58:27.736+0000: 10226: error : qemuMonitorIORead:513 :
> Unable to read from monitor: Connection reset by peer


The log is alos filled with the message below, it gets repeated over and
over and over.

2012-07-10 09:26:02.244+0000: 10229: error : virExecWithHook:328 : Cannot
