Comment 7 for bug 1824315

Here's what I found:

There's a qemu error in [1] with the following:

nova.exception.QemuGuestAgentNotEnabled: QEMU guest agent is not enabled

There's no qemu-agent package installed on the undercloud as pointed in [2], so I believe it's installed in the container.

Checking nova driver code at [3] I notice this failure is due the lack of image meta property hw_qemu_guest_agent.

So, I believe we are going to need some nova expert here to help us because validate-tempest role that execute tempest, create the cirros image in the same way, independent of distro, so I don't think it's related to how tempest is uploading the cirros image to glance, and this is missing.
I also notice that on this particular job, we are running 3 other scenarions, that are creating vm's with the same cirros image, and tests are passing...
