[Qemu-devel] [PATCH 0/6] Add -cpu host CPU type

[Andre Przywara]

Hi,

this patchset adds a new CPU type called "host" which mimics the host CPU
in many ways. It's main usecase is to reveal most of the CPU features to
KVM guests.
KVM provides in the kernel a feature to trim the guest's CPU bits to
be not more capable than the host's one. This is currently broken in
userspace (both qemu.git and qemu-kvm.git), so fix this on the way, since
without it most guests will crash.
Additionally allow control over the hypervisor bit, which is somewhat
special, because it's the only bit which is not present in the host,
but should be set in the guest.
Patch 1-3 should apply easily to qemu-kvm.git, Patch 4 needs a little tweak.
Patch 5 and 6 are entirely different, although it's broken there in a
similar way. If you need the patchset against qemu-kvm.git, drop me a note.

Regards,
Andre.
