From 36752c9b91f75aa3ff0f214a89f13d806cb2f61f Mon Sep 17 00:00:00 2001 From: Gleb Natapov Date: Mon, 11 May 2009 13:35:53 +0300 Subject: [PATCH] KVM: Do not migrate pending software interrupts. INTn will be re-executed after migration. If we wanted to migrate pending software interrupt we would need to migrate interrupt type and instruction length too, but we do not have all required info on SVM, so SVM->VMX migration would need to re-execute INTn anyway. To make it simple never migrate pending soft interrupt.
