Message-Id: <1243180230-2480-44-git-send-email-avi@redhat.com> Date: Sun, 24 May 2009 18:50:28 +0300 From: Avi Kivity <avi@...hat.com> To: linux-kernel@...r.kernel.org Cc: kvm@...r.kernel.org Subject: [PATCH 43/45] KVM: Do not migrate pending software interrupts. From: Gleb Natapov <gleb@...hat.com> 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.
