I added a summary of the changes I am planning, at: http://wiki.qemu.org/Features/CPUModels#Current_Issues_and_proposed_changes I'm sure I forgot lots of details, so feel free to send me questions and suggestions, or even edit the wiki page directly. On Fri, Mar 09, 2012 at 05:56:52PM -0300,

Resurrecting an old thread: I didn't see any clear conclusion in this thread (this is why I am resurrecting it), except that many were arguing that libvirt should simply copy and/or generate the CPU model definitions from Qemu. I really don't think it's reasonable to expect that. On Thu, Dec 15,

Hi, Recently I realized that all modern CPU models defined in /etc/qemu/target-x86_64.conf are useless when qemu is used through libvirt. That's because we start qemu with -nodefconfig which results in qemu ignoring that file with CPU model definitions. We have a very good reason for using
