Running nested VMs in Fedora 26 KVM / QEMU on Hyper-V
-
Creating a Linux VM on Hyper-V is easy. Creating a nested VM inside your Linux VM running on Hyper-V... well, it's not going to work out of the box.
Here's how to do it: https://www.timothygruber.com/hyper-v-2/run-a-nested-vm-on-kvm-qemu-vm-in-hyper-v/
Why would you want to? In my case, there was a developer who needed to compile code on a special Linux VM, and immediately needs to test it inside a throw-away VM running in there.
Doing this on his own or another physical PC or other means was not an option.

@tim_g Yuck. That's why they pay you the big bucks, right?
-
@tim_g Yeah that looks like a pain to do. Nice explanation though, thought you did well. Liked the few articles you have up, keep them coming.

Wouldn't this be a good case to use a LXC/LXD container and not have to mess with nested virtualization?

No, the throw-away (nested) VMs have to be Windows images that are used with the product systems.

Out of curiosity, why could he not make the throw away VM on top of Hyper-V?

He doesn't have Hyper-V, and we don't give users access to the Hyper-V Servers. No SCVMM, so no granular control over VMs and HyperV.

Oh, I guess that I was confused.
