Re: [libvirt] [PATCH] Add Skylake Cpu Model
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.
+ <!-- XSAVE CPUID[EAX=0xd,ECX=1].EAX -->
+ <feature name='xsaveopt'>
+ <cpuid function='0xd' eax='0x00000001'/>
+ </feature>
+ <feature name='xsavec'>
+ <cpuid function='0xd' eax='0x00000002'/>
+ </feature>
+ <feature name='xgetbv1'>
+ <cpuid function='0xd' eax='0x00000004'/>
+ </feature>
+ <feature name='xsaves' migratable='no'>
+ <cpuid function='0xd' eax='0x00000008'/>
+ </feature>

Currently, libvirt still think a Skylake cpu as Broadwell-noTSX

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
capabilities XML, but users won't be able to use it anyway.
