Subject: [PATCH 2/2] KVM: x86 emulator: Drop EFER.SVME requirement from VMMCALL
Date: Tue,  5 Apr 2011 16:28:31 +0300	[thread overview]
Message-ID: <1302010111-23431-3-git-send-email-avi@redhat.com> (raw)
In-Reply-To: <1302010111-23431-1-git-send-email-avi@redhat.com>

VMMCALL requires EFER.SVME to be enabled in the host, not in the guest, which
is what check_svme() checks.
