Guru meditation issues

[okizuka]

Hi guys, i'm not native english speaker!

My problem is that virtualbox works fine, and the day after he goes to guru meditation

My computer specs: AMD RYZEN 7, 32Go Ram, 2 X 500Go SSD

In my example i would like to make a new pfsense VM and crash

Sometimes, he do the same on windows 10 when i try to clone vm, sometimes works fine
I'll try older virtualbox builds, enable and disable hyper-V
Nothing work

Thank for reading me

Please choose a VM which exhibits the symptoms, and provide a VM log file. Make sure the VM is fully shut down, then right click it in the manager UI. Select "Show Log" and save "VBox.log" (no other file) to a zip file. Attach the zip here.

Please include the VBoxHardening.log file in the same zip.

It seems to be a conflict with Hyper-v, which is definitely enabled (and ideally, should not be).

00:00:07.427615 NEM: info: Found optional import WinHvPlatform.dll!WHvQueryGpaRangeDirtyBitmap.
00:00:07.427668 NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work...

Here are instructions for how to disable Hyper-v correctly.

Thank you, this fiw my issue, the thing is before i enable and disable manually hyper-v, hyper-v was never activate, maybe windows update setting it up itself?
Thanks mpack !

maybe windows update setting it up itself?

Yes, Windows does occasionally do that during an update. More often however it will be because you decided to try out a new feature, such as "Windows Subsystem for Linux 2" (WSL2) without realizing that this enables the underlying NEM (Hyper-v) engine.
