Comment 0 for bug 1180044

When *any* VMware vCenter managed data center contains no hosts to provision an image, the nova boot command will fail silently. Empty data centers without ESX hosts are usually left behind by administrator error. Removing the empty data center resolves the issue.

Stack trace from logs:

Work around: remove the empty data center.
