06-02-2021 I am working in a Windows 10 machine and I noticed I can't work with VirtualBox and WSL together. This is mostly due to Hyper-V.
After some research, the solution I found is quite uncomfortable.
If you want to use WSL, you will need to execute the following in an administrator promp (and reboot):
bcdedit /set hypervisorlaunchtype auto
DISM /Online /Enable-Feature /All /FeatureName:Microsoft-Hyper-Vi
If you want to use VirtualBox, you will need to disable the previous thing, so you need to execute the following in an administrator promp (and reboot):
bcdedit /set hypervisorlaunchtype off
DISM /Online /Disable-Feature:Microsoft-Hyper-V
