Well... I'm not familiar with file-based VDI provisioning, but I'm think
the problem is not in XCP (well, XCP have the bug, but it only trigger
state), but in some forgotten mount.

Check fuser/lsof output, and try to restart xapi (xe-toolstack-restart).

And look to /var/log/messages and /var/log/xensource.log, every domain
start it filling with huge amount of debug info (I sometime thinking,
that this info reduce domain start/shutdown speed at least half).
