Looks Windows Sandbox conflicts with VirtualBox
@moonman Yeah, it's actually kinda cool. It's a bit hidden, I rarely see it talked about.
It's just a temporary lightweight VM with a clean Windows 10 that spins up almost instantly and nukes itself when you close it.
@orekix It being just enabled disables Nested VT-x/AMD-V and makes Vbox VMs hang up few seconds after launch
@orekix Hyper-V does the same with Vbox
