Title:
nova snapshot, nova resume not working with libvirt_cpu=host-
passthrough and libvirt 1.1.1
Status in OpenStack Compute (Nova):
Invalid
Bug description:
Environment:
OpenStack version Havana
libvirt_cpu = host-passthrough
libvirt0, libvirt-bin 1.1.1-0ubuntu8~cloud2
qemu-kvm, qemu-utils, qemu-common 1.0+noroms-0ubuntu14.12
kvm 1:84+dfsg-0ubuntu16+1.0+noroms+0ubuntu14.12
apparmor 2.7.102-0ubuntu3.9
Kernel 3.5.0-44-generic
lsb-release Ubuntu 12.04.3 LTS
Problem:
I have set libvirt_cpu_mode=host-passthrough in nova.conf in compute node.
I launched the VM instance and then when I create snapshot of the vm, the vm
is left in SHUTOFF state and I cannot start the VM.
Also if I suspend the VM, I could not resume it also.
In nova-compute.log

I did not have the problem with libvirt 0.9.8 earlier, before upgrade
libvirt to 1.1.1
