Comment 7 for bug 1551703

Actually in this case it's a bit different from bug 1811235 but the same fix would apply. In this case the libvirt driver raises InstanceFaultRollback for the error:

https://github.com/openstack/nova/blob/9b2e00e015f22b2d876cd3c239af8e139040c8c8/nova/virt/libvirt/driver.py#L9546

That should now be handled here:

https://github.com/openstack/nova/blob/9b2e00e015f22b2d876cd3c239af8e139040c8c8/nova/compute/manager.py#L4718

https://github.com/openstack/nova/blob/9b2e00e015f22b2d876cd3c239af8e139040c8c8/nova/compute/manager.py#L8753

The vm_state gets reset to active because _resize_instance isn't passing in the instance_state and it defaults to ACTIVE:

https://github.com/openstack/nova/blob/9b2e00e015f22b2d876cd3c239af8e139040c8c8/nova/compute/manager.py#L8718

So we need to do like this change:

https://github.com/openstack/nova/blob/9b2e00e015f22b2d876cd3c239af8e139040c8c8/nova/compute/manager.py#L4591-L4593
