Version 1 of this patch was: Message-Id: <1307041990-26194-11-git-send-email-ehabkost@redhat.com http://marc.info/?l=qemu-devel&m=130704415919346 This version doesn't have the duplicate feature bits on extfeature_edx, though, as they are being removed from the Intel models (as they are reserved bits on Intel CPUs). Version 1 patch description: This patch adds Westmere as a qemu cpu model. The only additional guest visible feature of a Westmere relative to Nehalem is the inclusion of AES instructions. However as other non-ABI visible modifications exist along with fabrication changes, the CPUID data of the corresponding deployed silicon was altered slightly to reflect this. We've seen isolated cases where apparently unrelated yet slightly incoherent CPUID data has caused problems, most notably during guest boot. Providing Westmere as a model separate fro Nehalem allows us to more easily address such quirks.
