Kernel panic in Win11

I encountered the same kernel panic error code when trying to start a VM for a 32 bit linux system off of a .iso file, pasted below. My host OS is windows 11. Attached is the log from the VM. I already downloaded and installed the service pack and tried adding CPUs to the VM. I encounter a different error when I have more than one CPU, also pasted below. I've attached that log, saved as ..2cpus. Please advise on path forward to establish VM.

The logs contain:
Code: Select all
00:00:02.506348 ********************* End of CFGM dump **********************
00:00:02.506631 HM: HMR3Init: Attempting fall back to NEM: VT-x is not available
00:00:02.560633 NEM: info: Found optional import WinHvPlatform.dll!WHvQueryGpaRangeDirtyBitmap.
00:00:02.560687 NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work...
Which means Hyper-V is active and this prevents VirtualBox version 3.1.34 from working effectively.
See
viewtopic.php?f=25&t=99390 for further guidance. Please try the recommendations and let us know if there is still a problem.
The developers have been working on this issue for a considerable time and there may be a fix in Version 6.1.36 (on release) which will allow Hyper-V and VirtualBox to co-exist.

I disabled the Hyper-V from the control panel, and also ensured it was disabled via the command prompt. I kept getting the kernel panic error until I disabled Windows Defender's Core Isolation for windows 11. That process was keeping Hyper-V active, and interfering with the VirtualBox, and I saw it in the logs. Once I disabled that process, the VM worked!
Thanks for your assistance in trouble shooting the error with the VM!

Great, glad you were able to hunt down the 'extras'.
