oVirt 4.3.6

Attempted to build 10 VMs from a template, concurrently, and apparently overloaded the 1GB link to the iSCSI storage.  I now have four VMs hung in the Locked connection on the display, and no means to cancel, remove them.

The all have ‘Failed to complete VM **** creation.’ log entries, under Events.

Any suggestions on how to address?
