Hello,

I have a few VMs Windows 10 VM that will randomly get stuck and only show a black screen when consoling in and then ill be forced to reboot the machine to get it back up. Ive been searching the forum and found a couple things. Are there any other solutions to look at to stop this from happening?

I just installed the newest VirtIO drivers and also moved the nic to the VirtIO nic away from the intel e1000 nic to see if that helped.

Thank you for any help!
 
HI,
please post the config of the VM so we can see the current one qm config <VMID>, also your pveversion -v.

A few things to consider:

Is the VM in that case still reacable via the network (test if you get a ping, eventual services are still running, ...)?

@Chris: all my Win10 VMs started doing this recently and it only affects OVMF ones. It will shows "Guest did not initialized the display yet", the standard resolution change appears and switches to black screen. When they start they will run for some time and just crash silently becoming unresponsive.

did you change anything that could coincide with the "recently"? It seems that you are using nearly a year old packages. Can't tell if the problem will go away by upgrading, but applying (security) updates is certainly recommended, see: https://pve.proxmox.com/pve-docs/chapter-sysadmin.html#sysadmin_package_repositories

Hm, did I miss something? I was under impression I'm not using any obsolete packages, besides not being at 7.4 yet:

As for changing things I recently was testing v6 kernel line. v6.1 was working great for me. During the last cycle of updates I grabbed v6.2 and a few packages (see below). I reverted the kernel to 6.1, so that's most likely not that. However, my suspect would be edk2, if any - I didn't have time to test reverting that yet:

I narrowed down the black screen issue to a GPU passthrough. It only works once and then when attached to any VM it will make the VM unbottable with a black screen and no errors in logs. The only way to fix that is to do:

Code: 
# echo 1 > /sys/bus/pci/devices/0000\:0b\:00.0/remove
# echo 1 > /sys/bus/pci/rescan

Normally I would blame GPU's firmware, but nothing has changed in that regard.

Oh, sorry, I completely missed that you were not the original poster (and that @Chris already suggested upgrading for @jzuck74).

Yes, that is a likely candidate. How much RAM do your VMs with the issue have assigned? We had some reports where more RAM was needed with the new version (but for VMs that only had very little to begin with).

Good find! Yes, sounds like something goes wrong with releasing the device again.

That's most likely not it - one VM that does this has 1GB assigned but the other is 32GB. The bigger one uses static huge pages while the small one does not.

Anything I can try to debug this? I'm guessing it's not the VFIO modules itself as these are tied to the kernel. I can try reverting EDK and separately QEMU. I also see there's also "pve-firmware" - could that be a suspect as well?

I'd first try downgrading the EDK package. AFAIK, the issue with debugging EDK2/OVMF is that it'd need to be enabled at build time and that is not done for the release build. There's likely going to be a newer version of the package in the not-to-far-future (still needs to go through internal testing). I'll try to remember to post here when it's out, but you can also keep a look on the pvetest repository.

That is the firmware for the host kernel.
