Windows 11 guest doesn't shutdown but reboots

[Colin 't Hart]

Windows 11 24H2 guest on Proxmox 8.2.7
On shutdown it goes through the whole shutdown process but then the UEFI just boots it again...

Under VirtualBox 7.1.4 on macOS 15.0.1 Windows 11 23H2 shuts down as expected.

Where should I start looking?

I'm just trying to install w11-24h2 on prox 827 ... Have you used kvm-virtio drivers ? ... which version ?

thank you

status update : !'ve successfully installed w11 24H2 + virtio-win-0.1.262.iso (disk + net + vga-spice) ... VM shuts down as expected!

I have the same issue with proxmox 8.3.0

If you have HA configured for that VM, then you need to shutdown via PVE. If you shut it down from within the OS, then the PVE HA will restart it.

My Windows11 VM updated itself to 24H2 today and after that I can't shut it down, it will always restart instead. I did install virtio-win-0.1.262 but no change. How can I fix this?

No HA configured btw.

No HA. Just a plain vanilla VM.

Tell me and we'll both know. In some ways it's good to know I'm not the only one.

I'd appreciate if anybody from Proxmox could respond to this

Please try to uncheck Fast Start-up in Power Options -> System Settings, save the settings and report your findings.

That fixed it. The first two shutdowns I tried worked immediately.

Works for me, too. Thanks a lot @bochen415 !

 

[Colin 't Hart]

Yes, thanks from me too @bochen415 .
Hopefully upstream can be fixed to not reboot when fast boot is enabled in Windows.

Thanks @bochen415!

saved my day. This tip needs to be quoted in an official best practice for Win11 vm's...

I am experiencing this too. Latest virtio drivers and guest tools. Would be nice to have a fix rather than just hiding the symptoms.

Fast start-up hibernates Windows instead fully shutdown which is not recommended.
Disabling whole hibernation disables Fast start-up too
Within any Windows guest, CMD as Admin
powercfg -h off
btw, IRC, hibernation is available only with GPU passthrough, as virtual display doesn't support hibernation.

I no longer have this issue.
