Previously, the regular expression used to match and extract the load average from Nova hypervisors load average API was incorrect. As a result, the load average would not display if the number of users was 1.
With this update, the regular expression matches all possible load average formats, and the load average displays correctly in all cases.

Any idea on what is causing this bug? The load_average field in the openstackclient output comes from the hypervisor-uptime API [1]. The first thing I would do to try to narrow down the exact cause of this is try querying the same API with the nova client, so: $ nova hypervisor-uptime <hypervisor uuid> Internally, all the libvirt driver does is run the 'uptime' command on the compute host. I would also try SSHing to the compute host and running 'uptime' as a non-root user: $ uptime Once we have those two pieces of information, we can investigate further based on the results. Cheers!
