Centos guest not starting after upgrade host to Windows 11:scheduling while atomic

Post by sokotra »

After upgrading host machine to Windows 11, guest VM CentOS Linux (2.6.32-71.29.1.el16.x86_64) refuses to start with message:

BUG: scheduling while atomic: swapper/1/0x14010000.

On guest VM: two processors, RAM increased.

Any ideas?

Yesterday everything was ok, just upgrading to Windows 11 broke the VM.

Thank you! I thought I disabled it using Control panel through Windows features manager, but seems it was not true, only `bcdedit /set hypervisorlaunchtype off` and restart helped me. Now everything is working.
