When I install the 6.1.38 Guest Additions instead of the 7.0.0 or 7.0.2 GA on that Win11 Guest, it runs fine. No freeze anymore so far.Pipo wrote: Windows 11 installation works ok, Windows 11 Pro runs for hours without Guest Additions.
When I install Guest Additions and reboot, the VM always freezes after 1 to 5 minutes. Only Power Off is possible.
I found this workaround in a post for freezing Win11 guests on a Linux host.
