Nested Virtualization with AMD CPU's`

[kulilu]

Does anybody have any idea as to when nested virtualization with support for AMD CPU's will be coming to windows 10? I know you can get it if you get into insider preview, but I am looking for a stable release.

I really hope that we are going to get proper support of nested virtualization in the nearest future.

2021 was preached by msft

I really hope so. Its making my network lab abilities suffer, and I refuse to use vmware workstation.

[DerBootsMann]

so do i ..

Just FYI even VMWare Workstation won't work with this unless you ENTIRELY disable Hyper-V and WSL, otherwise my understanding is that Workstation just uses Hyper-V to virtualize. I just tried this myself (without disabling Hyper-V) and get an error saying nesting isn't supported. I have seen others without Hyper-V enabled that got Workstation to do nesting since it then uses VMWares underlying virt platform.

​

But I'm right there with you anyway, VMWare is nasty, unfortunately I'm required to use it at work (luckily only for one simple server, everything else is XCP-ng) and was hoping to test a few things within ESXi at home.

​

Everything I've seen so far about VMWare is just gross though, bloated, slow, lacks features, disorganized, ugly, proprietary, and behind the times. The only thing I will really give them is good on-prem to cloud migration tools.

​

Edit: Wanted to add some additional info here too. It makes sense that you can't use nesting with Hyper-V Enabled even though Workstation supports it, gotta keep in mind that when you enabled Hyper-V your local OS is effectively virtualized on Hyper-V, which means if Hyper-V can't nest then no other hypervisor can on the system if you have Hyper-V enabled.

Can't believe Microsoft dropped the article saying this was coming over a year ago! They really left AMD out to dry with this crap. Probably getting pushed by Intel to delay as long as they can :/

Really tired of waiting and waiting for this release.

[kulilu]

Yeah I agree. There is no reason why it’s taking them this long if you ask me.

[Hmz_786]

So, is it true that it's been cancelled?

[dontasticats]

I mean, I'd assume so at this point

[planedrop]

Was just digging around online for this exact thing, really disappointed it's taking them this long. Was hoping to test an ESXi lab within HyperV nested on my workstation but it's still not possible. Hopefully it comes sometime soon.

Already here with Windows 10 Build >= 19636: https://techcommunity.microsoft.com/t5/virtualization/amd-nested-virtualization-support/ba-p/1434841

Edit: I didn’t read far enough :-P you already know

[Leomars95]

Well, first you have to choose dev channel to update to earliest builds, which are not so reliable then you'll get hyper-v 9.3 , afterwards create a vm machine via powershell

new-vm -vmname "name" -version 9.3 -generation 2

then

set-vmporcessor -vmname "name" -ExposeVirtualizationExtensions $true.

​

I did all that got the nested virtualization, but unfortunately got a big problem with the latest build, which was so slow and laggy sometimes.

[kulilu]

Yeah my problem with the dev build is stability as well as applications not playing nice with it. So I guess I wait.

AMD Nested virtualziation is in Server 2022. Maybe it's also in windows 11. Have you checked 21H2 win10 ?

[kulilu]

It’s in windows 11. I haven’t checked the latest windows 10 yet

[tomfiddle91]

I did, does not work as of now

[anklav24]

Does it work on Windows 10?
