That system OS did not cycle, but the hypervisor it is on might have, of course. What is leading people ot think that the "server cycled"?
How can the hypervisor cycle and not the VM, unless the VM is on HA?
How can it not? The VM doesn't have any way to know that the world has stopped for a few minutes unless it has crashed or been told to shut down. To it, time just leaps forward and it doesn't remember what happened during those minutes.
What about what was in RAM? Is that some how saved? I suppose I could understand if the hypervisor paused the VM (saving the RAM state), rebooted, then started the VM again - is that a thing? if so - huh, didn't know.
Yup, RAM flushes to disk. It is called a "saved state." Same as your desktop going to sleep except that the VM has no idea it is happening because the VM itself has nothing to do with it.
Is this a typical thing that one would do when needing to reboot the VM host in a non HA environment?
For example - my power outage the other day, would I have been OK just saved stating my VMs and having the host be offline for a few hours instead of shutting them down?

That's the funny thing about memory that people rarely sit around and ponder. If I could record everything in your memory right now out to a disk somewhere... then I could dispose of your body. In five hundred years or in five million years I could take another body, load your memory into it and you would believe that "nothing happened" except whenever you looked at a watch, calendar or in a mirror you'd be confused because you can't figure out how you got where you were, why the time changed or why you look differently than you did - because you were "just" doing something else.
-
LOL - sure I understand that completely. I just hadn't considered it as part of the use case with VMs. Of course there's no reason it shouldn't work for VM's like it does for end users.

If you are on a buying spree and enjoy survival horror check out SOMA. It is by the same devs that made Amnesia. It uses this idea effectively throughout the entire game.

That was a crazy amount of activity for a good 15-20 minutes there. Amazing for so early in the morning.

Other then not having hot-swap bays... this is tempting - http://www.ebay.com/itm/HP-Proliant-DL165-G7-server-2x-12-core-AMD-Opteron-6172-48GB-RAM-750GB-HD-/221952681299?hash=item33ad692553:g:dwYAAOSwAYtWK-61

nice - could make a nice place to play with a bunch of linux VMs
I wonder how loud it is?

I am not complaining at all. And I think most everyone is having a hard time getting motivated to actually work

Very loud. I don't know if that has a RAID controller either. Those Opterons aren't the most power friendly.

definitely knew they are power hungery little beasts! no RAID? hmm.. might not be worth it then... have to drop a $400-$800 RAID controller ... hmmm.

Software RAID... the non-hotswap is an issue too but not that bad.

Can you do software RAID on the boot drive in Hyper-V or XenServer?

I'd run XenServer from a USB key and setup those drives in an MD array.

Does Hyper-V (Windows) have software RAID?

Does Hyper-V (Windows) have software RAID?
Well, a full install of Windows with the Hyper-V role definitely does. Does Hyper-V core? no clue.

@Dashrender It should, i believe you can create a windows software RAID with DISKPART

No, I wanted to see what the anti-virus solution did. User already opened the attachemnt, I most certain will be nuking from orbit.
