Thread-topic: [Xen-API] Create a Virtual machine with a specific UUID
Hi,
a short update on this subject, by calling both Vm.start_on and Vm.pool_migrate 
XenAPI methods I get an MESSAGE_METHOD_UNKNOWN exception.

Is there any way to perform a migration (live or not) using XenAPI?

Thanks

Mauro

Unfortunately no - XCP has not yet moved to xen-4.0 yet, we're still on 3.4.2. 
The current plan is to upgrade within the next 6 months or so.
