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! > _______________________________________________ > Cloud mailing list -- [email protected] > List information: > https://lists.wikimedia.org/postorius/lists/cloud.lists.wikimedia.org/ -- David Caro SRE - Cloud Services Wikimedia Foundation <https://wikimediafoundation.org/> PGP Signature: 7180 83A2 AC8B 314F B4CE 1171 4071 C7E1 D262 69C3 "Imagine a world in which every single human being can freely share in the sum of all knowledge.
