Bug Description
Currently, when you build two VMs at once, or resize two VMs at once, you can hit a race condition in XenServer's VBD.plug in XenServer 6.1 and later, and there are issues with tapdisk hanging during the VBD.unplug
It is apparently related to this change:

There is no public bug report, but the agreed workaround is to ensure you only have a single VBD.plug happening at once per VM.
The issue we have is running nova-compute in a VM means we can only have on VBD.plug at once inside the nova-compute VM.
