Re: [Xen-users] xen on amd64 or intel

[aschiefer@xxxxxx]

as far as i understand (i may be wrong here too) vt and pacifca support  
some operations in hardware (or plan to do so in matching chipsets), which  
earlier had to done in software (e.g. device i/o virtualization, mmu  
virtualization), from which one could expect at least some perfomance  
gain. but since the overall xen peformance is already close to non  
virtualized hardware, maybe it's not really worth waiting for (in case of  
linux).
