I tried to add the VMs by spinning them up manually and seeing them appear in Machines or by using a Pod. Neither method worked.
After seeing the machines appear in Machines, I did go to Configuration and set the Power to virsh. I was able to power up the machine from the UI.
Still - if I had VNC console attached - every time I would see the dreaded message that no bootable hard drives are found.
I looked for meaningful logs, but couldn’t find anything.
