Windows VMs shutting down unexpectedly !

[Nass]

Hello guys, my vm windows turned off frequently any one have an idea of the cause ?

How high is your hosts RAM usage? You could run cat /var/log/syslog | grep oom. If it returns anything, then PVE was killing the VM because your server ran out of RAM.

Does it really shut down? Or does it go to sleep due to the power safe powerplan and inactivity?
That once drove me nuts until I realised what was going on...

Windows update can also shutdown the VM on its own.

Update in my case wait my confirmation before reboot, so it's not the probleme.

Typically that's a restart according to my experience. A shutdown is weird.

What do the windows evebtlogs tell you? Anything?

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

Jep, but wasn`t uncommon here on PVE that a update-initialited restart failed with the VM sitting a in shutdown-like state.

This indeed indicates that either your OS crashed or it was powered off for instance through an out of memory condition as dunuin said.

Since this message is posted on the next boot: what happens before that?
