Cluster configuration:

2 Ironic

Sometimes instance failed with the following ERROR:

There is full log from nova conductor: http://paste.openstack.org/show/593017/

It often occurs when we just enrolled new ironic nodes, then wait some time (near 2-3min) and then tried to boot Nova instances.

Nova team, could you take a look? I'm not sure how we can assist here.
