QEMU does not support Westmere (Intel Xeon) CPU model
Setting the CPU model to Westmere (Intel Xeon server CPU) is not possible.
libvirt uses 'core2duo' as fallback:

$ qemu -cpu ?
x86 [n270]
x86 [athlon]
x86 [pentium3]

$ qemu --version
QEMU emulator version 1.0 (Debian 1.0+dfsg-3), Copyright (c) 2003-2008 Fabrice Bellard
An application test with high cpu load gives the timing statistics give:
bare metal virtual percent
X4560 cpu 50m28s 54m0s 107%
X5690 (westermere) 29m20s 38m0s 134%
Westmere seems to be available in the latest version of QEMU:
$ qemu-system-x86_64 -cpu ? | grep Westmere
x86 Westmere Westmere E56xx/L56xx/X56xx (Nehalem-C)
==> Setting status to "Fix released" now.
