I've got a VM (spi-tools-host-1) that I'm not

configuration. On AWS I would just back up all the storage and shut down the VM. Is
there some way to do that in this environment?
I suspect the answer may include, "Yo, dummy, you should have used puppet instead of
just installing things manually with apt-get". If that's the case, feel free to
say that :-)
You should be able to just turn it off, and whenever you want, just start it up again,
that will preserve the current
status of the hard drive.
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).
If you don't really care about stopping the current running processes, I'd
recommend shutting the VM off, and then
whenever you need to, turning it on.
In any case I do recommend though using puppet xd.
Or, is the VM so small that it's not worth worrying too much about the resources
it's wasting?
Your VM is quite small, so it's not much of a problem, though if it's not an issue
would be nice to save the resources
:)
Thanks a lot for being mindful!
