VirtualBox 6.x and Hyper-V on the same Windows 10 host

[marius_1956]

Some times ago I made some tests and noticed that I was unable to make VirtualBox run on the same (physical) Windows 10 PC where Hyper-v was installed.
On the same Windows 10 box VirtualBox and VMware Player coexist witout any problem (even if I use only one of them at the same time).
As VirtualBox is my preferred hypervisor I simply uninstalled Hyper-v.
Now I read that VirtualBox and Hyper-v can coexist on the same Windows 10 PC.
Is it correct?
Which VirtualBox and Windows 10 versions are required?
Is there anything else to consider before simply installing the Hyper-v role on my Windows 10 box?

It is occasionally correct, in the sense that they don't always immediately crash. It still isn't the recommended way tho.

VMWare Workstation and VirtualBox can co-exist because both are type 2 hypervisors, so it's easy to ensure that they don't both run at the same time. But Hyper-v is a type-1 hypervisor, so it's running the entire Win10 host OS as a VM, and that means VirtualBox is trying to run nested VMs inside an alien hypervisor. That's a completely different scenario.

I have VB 6.1.30 and Hyper-V and WSL2 working on Windows 10 along with a number of different guest OS's. VB 6.1.32 does not play ball with Hyper-V on a number of different PC's ad causes the guest OS to run very sloooow (crawl's along like a single core celeron)

You may hit issues on 6.1.30, but I would give it a go.

Many thanks for the useful information and clarification!
