Subject: [Qemu-devel] [PATCH v2 uq/master 0/2] KVM: issues with XSAVE support
Date: Fri, 13 Sep 2013 15:55:56 +0200 [thread overview]
Message-ID: <1379080558-16499-1-git-send-email-pbonzini@redhat.com> (raw)
This series fixes two migration bugs concerning KVM's XSAVE ioctls.
The second right now is only a theoretical problem, since the only
XSAVE-specific state is AVX and all machines with XSAVE also have AVX.
In the future, this will ensure that machines with MPX or AVX-512
do not expose those XSAVE states when using e.g. "-cpu SandyBridge".
Please review.
