Hi,

this message is just a hint that something went wrong, you have to check your logs to find the real cause, first of all nova-compute.log. This error message has been handled many times, a google search will get you plenty of possible causes. But like I said, first nova-compute.log, libvirt logs on your compute node(s), if there's nothing, check the control node(s) for nova logs (api, conductor, scheduler), if your instances use volumes, check the cinder logs.

Regards,
Eugen
