Actually, you can use XenCenter to do SXM. The SXM wizard will pop up 
when drag a host between pools, or between hosts without shared storage 
(or when the VM is not on shared storage). There is no explicit SXM 
option because we wanted it to just look like "migration". You can also 
explicitly tell XenCenter to do VDI.pool_migration, by clicking on the 
VDI in the SR's storage tab (it's a little confusing, I think).
And I'm glad to hear you think the performance is good. We were worried 
that the performance might have been an issue for people, but it doesn't 
seem to be the case in practice.
