Problem instantiating VM on my host (fails)

Community Support
1

Hello,

I have my frontend and KVM running on Ubuntu Server 18.04 within virtual Box on my 2015 Mac. I have connected the Host onto Sunstone but when I try to implement the ttylinux VM it fails with the logs below and the error shown below on Sunstone itself.

I have been able to passwordless SSH between both, I have tried adding the hostname to the ssh-keygen but I get the same results anyway with no change. When I run “virt-host-validate” I get one FAILURE which could possibly be the cause which leads to the question of how do I allow virtualization on either my mac or VirtualBox?

You are trying to use the KVM driver within a Virtual Machine, you need to enable nested Virtualization in order for the VM to create VMs, or, if you want to avoid the hassle, use the LXD driver instead.

I believe that both systems do have nested virtualization enabled according to Virtual Box. I’m not familiar with the LXD driver method, is there anything else I can try before switching over to that method?

Well, your host is not able to run KVM, you can try to manually create a virtual machine to confirm it. The experience when using the LXD driver is almost the same as KVM.

Alright, thanks for the info! I’ll try the LXD driver method but I think I’d still like to get it to work with nested virtualization so I’ll try the original method on my home PC, I was just hoping to be able to work on it on the go
