Open Stack

Hi,
I currently have 3 compute nodes on edge site1 where i am trying to launch
vm's.
When the VM is in spawning state the node goes down (openstack compute
service list), the node comes backup when i restart the nova compute
service but then the launch of the vm fails.

nova-compute.log
