From 8b18bc378224b4f195145b407b95768a289497e3 Mon Sep 17 00:00:00 2001 From: Avi Kivity Date: Tue, 5 Apr 2011 16:21:58 +0300 Subject: [PATCH] KVM: x86 emulator: Re-add VendorSpecific tag to VMMCALL insn VMMCALL needs the VendorSpecific tag so that #UD emulation (called if a guest running on AMD was migrated to an Intel host) is allowed to process the instruction.
