When deploying to a compute node hosted on a PowerKVM system, nova boots fail to spawn when video type is set to 'cirrus' in the XML definition. This is the default value set and was a part of this blueprint:
https://blueprints.launchpad.net/nova/+spec/libvirt-video-driver-selection
and this change:
https://review.openstack.org/#/c/58614/8
When trying to launch an instance, the following can be observed on the PowerKVM compute node: http://paste.openstack.org/show/62144/
and the XML definition here: http://paste.openstack.org/show/62145/
One possible solution for this would be to detect the architecture of the compute node and to not default video type to 'cirrus', until PowerKVM supports cirrus emulation. This is already partially done by https://review.openstack.org/#/c/66992/10 and can be used in https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L3211-L3225 without causing issues with the current implementation. |
