libvirt ERROR in n-cpu log after successful tempest run

This is what it seems to be hitting:

    https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L809

I think it's trying to "destroy" (i.e. "force stop" in libvirt's parlance) a non-existent domain -- which is not really catastrophic, and that's why Tempest runs must be succeeding?

[Going through this bug as part of periodic triage.]

I just checked for the past few weeks successful tempest runs, I can't find the error message noted in the Description.

    http://logs.openstack.org/03/67703/3/check/check-tempest-dsvm-postgres-full/de93545/logs/screen-n-cpu.txt.gz

While I agree that it'd be nice to pin point the root cause of the issue, but I don't think it's worth the time to investigate now as it's not occurring consistently.

Please re-open this bug if it occurs again.

Sorry, I was wrong.

From logstash, it seems to happen consistently -- http://goo.gl/w2wqP1

I had a brief chat with Daniel Berrangé on #openstack-nova, and like I noted in comment #1, he has this to add:

    [instance: 8e34bcb4-6f64-4a92-b3db-7756f4473c09] Error from libvirt during destroy. Code=42 Error=Domain not found: no domain with matching uuid '8e34bcb4-6f64-4a92-b3db-7756f4473c09'

means:

Nova is trying to tell libvirt to destroy a guest which has already gone. As an error, it is pretty harmless from libvirt's POV, but it might indicate an unexpected scenario from Nova's POV.
