Subject: [PATCH 0/2] Fix vmx real-mode state leakage
Date: Mon, 3 Jan 2011 14:28:50 +0200 [thread overview]
Message-ID: <1294057732-11364-1-git-send-email-avi@redhat.com> (raw)
When emulating real mode, we fake some segment state to conform with vm86
mode. Unfortunately, we allow the guest to see this fake state if we live
migrate when this state is in effect. This patchset corrects the problem.
Avi Kivity (2):
KVM: VMX: Save and restore tr selector across mode switches
KVM: VMX: Avoid leaking fake realmode state to userspace
