Hi! Thanks for getting in touch. :)
To be honest, I'm surprised you got as far as you did -- like Michael
says, I'm currently working towards a proof of concept, so none of what
you've tried out so far is really meant for use outside of that proof of
concept.

Pretty close -- spectrumPackages is an attribute set containing lots of
derivations, which is why you end up with lots of numbered result-*
symlinks. If you do -A spectrumPackages.spectrum-vm it'll just give you
a single result symlink pointing to that, and you won't need to go
hunting for the right one. :)

I'm surprised -- this has worked for me before, although it's been a
while since I tried this so maybe I changed something.

Yeah, this is a known issue. I have a patch[1] for it but didn't add it
to the package since I mostly have been working with my own source
builds of crosvm.

Never tried that, so I don't know anything about it I'm afraid.

Yeah, crosvm needs to be CAP_NET_ADMIN for that (which is difficult to
do with Nix). You can make a TAP device yourself iproute2 and use
--tap-fd to tell crosvm to use it, or you can use the mktuntap program I
wrote (with a privelege drop after running mktuntap), like this:
sudo mktuntap -pvB 3 \
sudo -u $USER -C 4 result/bin/spectrum-vm -- --tap-fd 3

Like Michael said, there's a lot I need to do before it's really ready
to use like this, but I am working on it (or at least I will be again
once my anti-burnout break ends). Once I am, I hope to be more active
on the lists again. I used to post weekly status updates, and would
like to get into doing that again once I'm back because they were a
great way to keep people up to date with the project and for me to have
a record of what I'd been doing. Reading some of the old status updates
should give you a bit of a feel for where things are, although things
are a bit further along than they were when I wrote the last one because
I put the status updates on hold to try to chase a funding milestone.
Hope that's all clear -- please ask more questions if you have them,
although if it's anything particularly in the weeds I might wait until
I'm back from my break to answer. :)
