Title:
Snapshot failure with VMwareVCDriver
Status in OpenStack Compute (Nova):
Fix Released
Status in OpenStack Compute (nova) grizzly series:

Status in The OpenStack VMwareAPI subTeam:
Fix Committed
Bug description:
I am unable to get snapshots working in my dev setup with the
VCDriver.
snapshot API call claims to succeed, but we get an internal exception
(below) and the snapshot stays in 'queued' status in Horizon.
The relevant code is here:
https://github.com/openstack/nova/blob/master/nova/virt/vmwareapi/vmops.py#L515
It seems like the underlying snapshot succeeds, but the attempt to copy the
disk afterward fails. Browsing the datastore, I see that a vmware-tmp
directory was created, but I do not see any files in it.
