How can I add networking to a minimal template VM?

[Zbigniew Łukasiak]

I am trying to setup a printer AppVM as described in
https://www.qubes-os.org/doc/network-printer/ - i.e. first I am trying
to create a template VM and configure printing there.

I cloned fedora-28-minimal for the template VM.

I tried to configure the printing without networking - that should be
possible, but I failed at it and I think it is still useful to be able
to switch on networking temporarily in a template VM.

Then in "Qube Settings" I changed Networking from "default (none)" to
"sys-net (current)" (I tried also "sys-firewall").

Unfortunately it boots without networking - so I tried to set it up manually:

bash-4.4# ip addr add 10.137.0.27/32 dev eth0
bash-4.4# ip route add default via 10.137.0.6 dev eth0
Error: Nexthop has invalid gateway.

At one point that worked, but now it stopped with the above error message.

have you read www.qubes-os.org/doc/templates/fedora-minimal ?

Your ip command does not work because you dent have a route to the IP your
are setting as default.
If you install the relevant qubes-core-agent-networking etc then you
should get IP set up automatically.

Yeah - somehow I missed this one. Later I found it - but thanks :)

Eventually I went with the normal fedora template - I need it for the
printer vm and there I need all the packages to display stuff - so I
guess the difference would not be that dramatic anyway.

I don't quite get that - because 10.137.0.27 and 10.137.0.6 are in the
same subnet (and I tried /24 as well).
But whatever.
