[Pkg-libvirt-maintainers] Bug#537445: restoring leaves kvm-instance in unusable state

Package: libvirt-bin
Version: 0.6.4-1
Severity: important
I am using libvirt-bin together with kvm 85+dfsg-4.
I can use virsh to save the state of my machines just fine; at least
there is no error reported. However, if I try to restore the
machine, kvm starts fine and I can connect to the qemu pty, but when
I connect to the ttyconsole, the login prompt is not there. A minute
later, the VM reboots and then works fine.
During save, the host's kernel log shows
kvm: 22871: cpu0 unhandled rdmsr: 0xc0010117
When I restore, I see
kvm: 19696: cpu0 unhandled rdmsr: 0xc0010117
kvm: 22871: cpu0 unhandled wrmsr: 0xc0010117
kvm: 22871: cpu0 unhandled rdmsr: 0xc0010117
kvm: 22871: cpu0 unhandled rdmsr: 0xc0010117
followed by 240 of those messages:
vcpu not ready for apic_round_robin
[4/second for precisely 60 seconds]
and then
kvm: 24503: cpu0 unhandled wrmsr: 0xc0010117 data 0
just before the reboot.
This might be a kvm problem, but I can't figure out how to
save/restore with kvm directly, so I am filing it here.
