Nested virtualization

[adoni...@gmail.com]

Hi guys,

Is it possible to install let's say Virtual Box inside a Qube? I've done some reading and all people seem to say is that it should be possible, but nothing conclusive.

[nicholas roveda]

Yeah, currently I'm using LXC Containers inside AppVMs.

What do you need exactly?

VirtualBox definitely did not work for me, but I only tried it once and mostly out of curiosity. I can't remember the error... something about being unable to load a kernel module maybe?

this should be a faq somewhere, it keeps getting brought up.

xen supports nested virtualization, see here: https://wiki.xenproject.org/wiki/Nested_Virtualization_in_Xen

but, this is disabled in qubes because of the large attack surface it introduces. containers, like docker and lxc, are possible, as is emulation like running qemu without kvm extensions or virtualbox with 32bit guests with acceleration turned off.

you could make your own qubes build with it on. look for marmarek in qubes-devel for threads on that.

Hi guys, thanks for the responses, I will have a look at it.

What I need in this case in particular requires VBox, it is Genymotion, an Android emulator.

Hard to do an FAQ on this, because there are so many ways to try to do
nested virtualization, and they don't all turn out the same way. But
feel free to submit a PR if you like. :)

this might help.

heres a quick guide to stand alone vms, https://www.qubes-os.org/doc/hvm/

[adoni...@gmail.com]

Hmmmm.. so Windows and then try to emulate android... I may give it a go, although I'd rather have a Linux VM with VBox in it

[Tai...@gmx.com]

Windows? no that's just the guide obviously you can use linux.

I can't see any reason as to why virt wouldn't work on a HVM assuming
the correct cpu flags are passed through.
