Hello everyone,

I'm no longer able to boot up a company issued VM. Right after the kernel selection, the critical error is raised.

Host system data:
Windows 10 Enterprise
Version: 2004
OS build: 19041.746

I tried some Hype-V stuff (but disabled it again) and need to get my VM back up again.
I tried to find my way through the log but I can't see what the error Guru Meditation 1155 (VINF_EM_TRIPLE_FAULT) is implying.

Any hints why the VM isn't starting anymore?

Best regards!

Possibly it's because you now have Hyper-v enabled.

00:00:03.618637 NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work...

See last post in FAQ: I have a 64bit host, but can't install 64bit guests.

Thank you, that did it. I thought I disabled it (went to optional features and unchecked all Hyper-V related things) - and they were still unchecked - but after putting in the command and shutdown/boot it finally worked again. Should make it a habit to go the CLI first and "hard reset" the machine each time

Thanks for reporting back.
