Comment 5 for bug 1436166

Julian,

if you see line 2318 mentioned, you will see we are catching an uncategorized exception:
http://git.openstack.org/cgit/openstack/nova/tree/nova/compute/manager.py#n2318

if you grep for "Unexpected error" you will see it comes from:
http://git.openstack.org/cgit/openstack/oslo.concurrency/tree/oslo_concurrency/processutils.py#n69

So we should be catching processutils.ProcessExecutionError just like we catch exception.FlavorDiskTooSmall earlier in manager.py

you may end up with something like this...
