When I've previously attempted this, I had some crosvm thread crash with
a seccomp violation because it tried to log something. If you
--disable-sandbox, it might work or at least give you a clearer error
message.

There might be some helpful stuff in the Mesa repo as well, because lots
of the latest graphics stuff is being done for crosvm. A quick grep
found me the Venus (Vulkan over virtio-gpu) documentation, which
describes testing with crosvm, and the script they use to run crosvm in
CI. It also reminded me that there are two different virgl
implementations in crosvm, virgl_renderer and virgl_renderer_next. I
think last time I tried I had better luck with virgl_renderer. You can
set buildFeatures in the Nix expression to experiment with them.
I hope some of that's helpful. I really wish I'd taken better notes
the one time I got this to work.
