Use OpenSSH.  ;-)  The root file system is indeed volatile.

The OS declaration is not in the VM, unless you share it with --expose
or --share.

Networking works out of the box in the VM.

If you want the VM to be reachable from the outside, the easiest
solution is port forwarding:

The OS declarations only describes the OS in the VM, not the QEMU
parameters.

Just “unalias ls” (the alias comes from the default ~/.bashrc).

Maybe we could move the note in
<https://www.gnu.org/software/guix/manual/html_node/Invoking-guix-system.html>
higher, in the description of the ‘vm’ sub-command?

HTH!
