VM going blank/not responding?

[jzuck74]

So I have about 20 Windows 10 VMs running and tonight I had 2 of them stop responding. They were running and pingable but I couldnt getting vnc or console into them. I hard reset the VMs and they came back up but Im just unsure what would have caused that. I dont see anything in the proxmox logs or the windows logs (at least nothing helpful). Both VMs lost two files. Which is concerning (luckily I keep good backups) but I'm assuming that's from not currently having the hard drives set to writethrough.

Anyone else have this issue?

Hi,

I would check the monitor at the time when the VMs are not responding to see if the I/O is high or/and what happened, this will give you a hint to where you should look.
