Looking in https://horizon.wikimedia.org/project/instances/43d3e9f2-b7d5-4a51-92b6-6a636839d66f/, I also see  "Shelve Instance"; what does that do?  I'm actually kind of curious about that last one because in my exploring, I accidentally clicked it, but other than seeing a "shelving" progress bar appear, it doesn't seem to have actually done anything.  My instance is still running normally.  Fingers crossed :-)

There's actually several ways:
* pause -> will preserve the current running status, with whatever is on ram. It will store the VM ram info on the
 hypervisor RAM, so it will stay on the current hypervisor but will be fast to start.
* suspend -> similar as above, but storing the VM ram on disk.
* shut off -> will turn the OS on the VM off, same as turning off a bare metal, the VM OS will stop any processes and
 such, and will have to boot when turning it on (slower, but allows moving the VM easily).
