How do you expect to do live migration of a machine that has a PCI
device assigned?  What if you migrate to another server that does not
have that PCI device, or has it, but at a different bus location?  This
could cause major problems in the machine after migration.  Xen doesn't
know (and doesn't care) what type of PCI device you're passing through,
so what if it's a storage controller?  If you're allowed to migrate a
machine with PCI devices assigned, and you migrate one that has a
storage controller assigned, the machine is going to crash.

Sorry, I missed the beginning of this thread, but what type of device
are you passing through?
