Enable nested virtualization for the VM runners
For faster performance when testing VMs with QEMU it could be beneficial to enable nested virtualization for the VM runners.
At the time of writing the following projects have a use case for this:
- arch-boxes (for testing the built images and testing with VirtualBox in the future)
- archiso (perhaps for testing the ISOs in the future)
- mkinitcpio (perhaps for testing mkinitcpio in the future)
- infrastructure (@dvzrv is working on some Ansible Molecule stuff where VMs could be useful)
Some concerns have been raised earlier about the safety of this, so let's discuss it :)
