Description of problem:

- run vm with os installed 
- migrate vm from host A to host B 
- VM moves to state: unknown '?' for several minutes
- VM moves to state UP

notes:

when I query the logs, I see that vmGetStats is sent on vm and vdsm returns the following for 4-5 minutes: 

Thread-3998::DEBUG::2012-02-29 17:46:19,596::BindingXMLRPC::854::vds::(wrapper) return vmGetStats with {'status': {'message': 'Done', 'code': 0}, 'statsList': [{'status': 'Migration Destination', 'hash': '0', 'acpiEnable': 'true', 'pid'
Thread-4002::DEBUG::2012-02-29 17:46:21,617::BindingXMLRPC::848::vds::(wrapper) client [10.35.97.30]::call vmGetStats with ('52cb68fd-00bb-4dbe-a17c-b63c372daf16',) {} flowID [93b8240]

please note that during that time, vm status is running on libvirt.
