Comment 18 for bug 568445

AFAIK, this is the place to post feature requests for virt-manager, at least this is where their website directed me. Intentionally selecting a default mode that results in very poor performance (about 1/5 less) when the upstream for the virtualization engine (qemu/kvm) clearly indicates that another mode is preferable is (IMHO) a bad choice. Furthermore, from what I can tell, virt-manager doesn't appear to provide any means of changing or overriding the default. A user must instead manually edit the server's XML definition of the VM in question.
