A VM in ERROR is not always a failed build. If the server was created but the link back to
Infrahub was never written, Infrahub shows ERROR or CREATING with no usable openstack_id while a
perfectly good server of the same name is running. This scans both sides in bulk and pairs them up by name —
and finds the reverse too: OpenStack servers that no Infrahub record claims, which is what
Suspected Orphan VM was meant to catch before its input metric went empty.
Run a scan to begin. It lists every server in all four regions, so it takes a few minutes.
