Description Dor Laor 2009-11-24 17:54:38 EST 
Description of problem:
Potential migration failure due to invisible physical cpu state:

Subject: [COMMIT master] KVM: x86: Add KVM_GET/SET_VCPU_EVENTS
Date: Thu, 19 Nov 2009 15:34:07 -0000
From: Avi Kivity <avi@redhat.com>
To: kvm-commits@vger.kernel.org

From: Jan Kiszka <jan.kiszka@web.de>

This new IOCTL exports all yet user-invisible states related to
exceptions, interrupts, and NMIs. Together with appropriate user space
changes, this fixes sporadic problems of vmsave/restore, live migration
and system reset.
