VirtualBox 6.1 and Hyper-V - vbox unusable

Hi,
I have a system with WSL2 enabled.
Virtualbox is able to boot, but apart from that, it is practically unusable.
Performace is terrible, a click sometimes takes seconds, same for keys being pressed.
Disabling WSL2 and using WSL1 (no hypervisor) fixes all this.

Yes. VirtualBox and Hyper-v compete for the same resources. What is your question?

While trying to use VirtualBox, there was a single, IDLE wsl machine started, so no resources competing with VirtualBox.
no question, I was just hoping this was fixed since 2018

Not exactly true. Hyper-V is a type-1 hypervisor, meaning it touches the hardware even before the host OS and definitely before Virtualbox, which is a type-2 hypervisor. So when a service requiring Hyper-V is active, even if that service is not taking CPU cycles, Hyper-V is active and in constant interference with Virtualbox.
The capability of running Virtualbox on top of Hyper-V is an ongoing dev project and is not there yet with your host and VM OS's.

thank you! all clear now!
ps: I have migrated my VB machine to win10's own Hyper-V (gen1). The new vm works without issues.
