How to reset your OpenStack services to "Up" in your IBM Cloud Manager dashboard for a vSphere cloud

While trying test and manage components in your vSphere cloud, you may see "Services Down" in some parts of the dashboard. For example, under "Host Aggregates":

I basically found that restarting all of the "nova*" services on my controller to be the answer to this problem.

The one-line answer is to log into your controller node as root and run the following:

for i in `systemctl -a | grep \.service | grep " active"| grep nova | awk '{ print $1 }'`; do systemctl restart $i;echo $i; done

So it's iterating through the results of the 'systemctl -a' command that contain active services containing the word "nova", and restarting each of those services. After you run the above, you should see that it shows "Services Up" for all availability zones on all hosts (since in a vSphere cloud, these services are all running on the controller node, rather than on the VMware nodes themselves).
