Hello friends,
I have a tale of woe around a relatively new server (Ryzen 5700G, 32gb Dell RAM, 2tb Toshiba NVME) whose Windows guests started having weird but fairly consistent problems a few weeks ago. The short version is that both Windows 10 and Windows 11 guests, after going a couple months flawlessly even with GPU and PCIE passthrough shenanigans, now fail to run certain applications and/or installers, and others exhibit weirdness like visual corruptions (text changing shape and size, dialog box buttons being invisible until hovered, other similar problems). There are some other behaviours but one thing that's quite consistent is that for VMs on this host, I can't run the Microsoft Teams for Work and School installer; it crashes every time. Same with the Discord app installer. Both report crashes with Squirrel Installer having various errors, currently System.IO.* errors. I think these might be partly spurious. The point is, Windows boots and can run some apps flawlessly (web browsing doesn't seem to be affected, for example) but it isn't usable for work (or gaming!). To fix, I have:
- Installed Windows VM on a different backing storage in the same host formatted as default ext4 in case it's something weird with my drive (ZFS on a single NVME drive, the blocksize changed to 64kb) - no change
- Installed both Win10 and Win11 on different VMs - behaviour is same on all
- Attempted various configurations with different storage virtual hardware (virtio block, virtio scsi), different CPU types (amd64, host, epyc-rome)
- Installed Linux desktop VMs on same host to see if anything weird - if so, I can't see it; Linux guests seem fine
- Stood up a separate proxmox host, installed a VM from the same windows ISO and tested (no problem). Then took a backup of that machine and run it on this host - problem exists.
I feel like I'm going a little crazy, especially since these VMs ran flawlessly for several weeks. I beseech you, tell me where I have strayed from The Path.
thanks,
