Hi Jirka
Thanks for your comments,, the qemu patch is on the way, check
https://lists.gnu.org/archive/html/qemu-devel/2016-04/msg03951.html
Even we cann't use qemu to boot a Skylake cpu virtual machine, but if we
specify in host mode, we still can
And besides, the follow cpu feature has already in qemu tree.

Adding a new model to libvirt when there is no support for it in
QEMU makes no sense. The only benefit will be seeing Skylake in
