Oggetto: [Tails-dev] Seeking advice on building Tails in a VM
Hello Tails Development Team

I was going through some of the documentation regarding building[1]
"Tails" distribution. I have hit a wall regarding continuing the build
beyond making sure there is a sane development environment with the
right set of tools.

The problem I face is with respect to the KVM. Since I do not have
direct access to a bare-metal server / a server which runs Xen
Hypervisor capable of running a domU with Debian / a Linux VM with
nested virtualization support where I can do the build via
vagrant-libvirt using KVM back-end. The builds fail with a call to
"virDomainCreateWithFlags".

I have access to VirtualBox but looking up online that is not sufficient
enough to do VT-d/VT-x passthrough to my guest Linux. My bare-metal
machine is not equipped to handle builds like Tails.

I also do not mind Vagrant[2] trying use a different back-end like Qemu
without KVM if needed to do the builds, but I am not aware of how to do
this in the current setup.

Looking for suggestions or pointers or documentation for getting this
build working without too much hassle.

Thank you
