My Windows VM always stops after a while

[lok...@gmail.com]

I have a Windows VM where I run Outlook for work purposes. It works great and I keep it in a separate xfce workspace. I'm running it in desktop mode (i.e. the Windows desktop is in a single Xfce window).

After a certain amount of time (hard to say how long, but I'd guess it's in the 30 minute to 1 hour range) the Windows desktop disappears, and in the Qubes manager the Windows VM is marked as yellow. It will stay yellow until I hard-kill the VM.

Does anyone have any idea what is going on, and what I can do to fix it?

I notice this problem when a Windows VM is left running, but doesn't
receive any user input for 30min or more. The window will disappear
when I'm not looking and I later find the VM stopped.

In my case the solution is to use the VM, and it is reliable until the
work is finished and I shut it down. Just a thought - have a look
through the power saving & sleep options. It might be trying to "save
power" and causing problems with Xen.

Thank you. That seems to be the cause. Power saving was indeed enabled with the system configured to suspend after 30 minutes. I turned it off, and the Windows VM hasn't crashed yet.
