Great.

No, everything works as expected.  The /dev/kvm thing is an annoyance
that was introduced just a couple of days ago, and we’re working on
fixing that, as you may have seen.

Yes.  Apparently you’ve been building from source.

Guix can build from source, or download pre-built binaries, known as
“substitutes” (see
<http://www.gnu.org/software/guix/manual/guix.html#Features>.)

On x86_64-linux and i686-linux, it’s possible to get pre-built binaries
from hydra.gnu.org, with the caveat that currently these binaries cannot
be authenticated.

Nothing wrong.  It just happens to be building from source.

Everything that’s built is kept in /gnu/store, unless you run ‘guix gc’.
See <http://www.gnu.org/software/guix/#documentation>.  :-)
