At school (from home) we are working with Mikrotiks in Virtualbox. Unfortunately for some reasons, my Mikrotik VMs started crashing a few weeks ago. Linux VMs (that work like Clients for those mikrotiks) do not crash.

https://vosaspseplzen-my.sharepoint.com ... Q?e=0ZYkPy Here is the Logs folder. It crashes about 30 seconds after booting up, even on the login prompt. It is a custom built PC.

Specs:
AMD Ryzen 5 1600
Gigabyte AB350 Gaming 3
16GB DDR4 2666MHz
Radeon RX 5700, driver 20.12.1
Windows 10 20H2

This does not happen when I run those same VMs on Catalina, only on Windows

Zip and attach logs locally like you did with your previous topic's images: viewtopic.php?f=6&t=100905&p=489757#p489757

I removed mention of the Hackintosh: OSX guests on non-Apple hardware

Re the guru meditation, Hyper-V is enabled and needs to be disabled. See HMR3Init: Attempting fall back to NEM (Hyper-V is active).

Sorry, I keep forgetting I can upload directly here. I mentioned the *redacted* to point out that this is definitely a Windows issue. HyperV is disabled, but I have Windows Sandbox enabled. Will try to disable that and see if it helps. Just weird that only the Mikrotik VMs crash, not the Kubuntu guests

Hyper-V is still enabled.

HyperV was disabled in "Turn features on or off". Well I guess it was really Sandbox, I have been staring at a Mikrotik VM for about 2 minutes and it hasn't crashed yet. Just wondering, what line in the log tells you it is HyperV? Btw thanks for the help

Read the appropriate tutorial link I posted.

Thanks!
