Hi!

Usually you get:

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


when you change permission in libvirt (root I presumed) which is not
necessary.

2012-07-10 09:26:02.244+0000: 10229: error : virExecWithHook:328 : Cannot
> find 'pm-is-supported' in path: No such file or directory


This error is harmless and can be easily solved by installing the following
package:

sudo apt-get install pm-utils -y


Do you have something in the nova-scheduler logs?

Cheers!
