RE: [Xen-ia64-devel][PATCH] support more than 8vcpu for windowssever 2003 SP1

["Yang, Fred" <fred.yang@xxxxxxxxx>]

Alex,

Windows Server SP1 will show running 16cpus on native Tiger4 systems.
With this patch the Guest Windows can get to the same behavior rather
than only 8 vcpus without patch.  For Datacenter version, it is shows
the similar behavior.

Thanks,
-Fred
