I'm running two servers with dual Xeons, HT enabled, EM64T enabled, one with 
4GB, one with 8GB Ram under xen.
Works without major problems, except for a faulty SCSI driver (which fails 
under plain linux, too) and "irq 18 occured, noone cared" kernel messages 
when attaching/detaching USB devices.

MB is from Supermicro.

Some older boxes (2GB Ram, dual Xeon without EM64T but with HT enabled) are 
working nicely under xen, too.
