[SOLVED] vm won't boot on virtual box, conflict with hyper-v

[valyfox]

Hi!

I have 2 kali linux and one windows 10 vm on windows 10 as a host. They worked perfectly but suddenly they would freeze on boot and I would get an error message when starting the windows 10 vm.
I think this is caused because I activated the windows sandbox on the host pc, but now I have turned it off and the wm still won't boot.
I also tried reinstalling virual box and recreating the vms. Also I tried vmware to see if it was a problem with virtual box but the vm still won't boot.

I've attached the log files for all the vms.

Thank you in advance to anyone who can help me with the issue.

If you enabled the Windows sandbox feature, then that will have in turn (re-)enabled Hyper-V, or the Hyper-V 'engine' if you don't have a full Hyper-V install. That will then limit VirtualBox performance because it won't have access to the VT-x support it needs.

First, try the advice here: viewtopic.php?f=25&t=99390
