AMD Zen2 Ryzen nested virtualization help needed

Featured Replies

I have 3950x on x570 taichi, windows 10 os build 20180

 

i tried different method and different version of windows, still no luck, anyone get this to work?? 

-tried host-passthough, host model and spaceinvander's nest on nest off script, 

 

 

i really want to run hyper v and android emulator(nox) on windows, running bliss os /android x86 just doesnt work that great.

 

thanks in advance~  

 

Microsoft hasn't added support yet, last I looked into it.  Only Intel, and I believe pre-zen amd is supported currently.

instructions are in the lined post, other than that you will need to enable nested virtualisation in unraid, steps mentioned here:

make sure you backup the vm before attempting these changes.

Tried, doesnt work. this is what i called "spaceinvader's script"

Just wanted to update I've been able to successfully get nested virtualisation running on my AMD 1950x after a few fails over the previous years.

Use case for needing this is to use Docker Desktop as part of my integrated development toolset.

 

So what did I need to do? I set the following via a script (SpaceInvader's from memory)

modprobe -r kvm_amd
modprobe kvm_amd nested=1

 

After creating a backup of my vdisk in case the changes bricked my VM, I installed docker desktop, which then required WSL2 installed (WSL2 is basically a mini hyper-v vm).

So installed WSL2, rebooted... the reboot never recovered :( oh crap... force stop.

 

Started VM one more time to see if it would recover... woohoo everything is working now :)

 

These are the same steps I had tried on previous attempts, so a newer kernel/qemu and/or windows has made this possible.

Thank you for reporting.

It's windows that made it possible.
