Windows 11 Pro 24H2 VM Random Freezes on XCP-NG 8.3
-
@DevilDan If the problem shows up on older Windows versions I would start suspecting a few other factors.
- Do you have any Windows PV drivers installed?
- Could you switch back to the Realtek NIC model instead of Intel e1000?
- Does it happen on all VMs at once or just one VM at a time?
- Any issues with Linux distros?

No issues on Linux VMs, the problem only occurs on Windows 11 24H2, 23H2 (so far) and Windows 10, all running in UEFI mode.
- No issues so far on a new Windows 10 VM running in BIOS mode.
- I'm always installing Xen Guest drivers 9.4 (we also tested without them).
- The VMs have nothing special installed, it's just a clean Windows setup.
- I don't remember if the issue appeared on both Windows versions at the same time, so I can't confirm a correlation, but it's a possibility.
- I had some "coalesce" issues on another Linux VM, but that's been resolved, and it doesn't seem related.
- I already tested both Intel and Realtek NIC models, same issue. However, I'll switch everything back to Realtek just in case.
- Currently, I have a Windows 11 24H2 VM and a Windows 10 VM (I deleted Windows 11 23H2—it was the most stable and used less CPU than 24H2, but since I'm testing, I'll stick with 24H2).

I also remember having installation issues and freezes with PFsense VMs or performance slowdowns with OPNSense in UEFI mode, I think. It feels like UEFI isn't that great?
