Guix VM can't connect to the Internet

Guix VM can't connect to the Internet

Hi, in light of the 1.0.0 release, I tried to download the Guix VM
image, to try and configure a workable setup within a Qemu session
before installing it.

But `guix package pull` wouldn't work, because no connection could be
established. Running `ping` on any server, would just inform me of
dropped packets, `ip link set eth0 up` wouldn't change anything.

I tried altering the quemu flags:

	qemu-system-x86_64 -net user -net nic,model=virtio -enable-kvm \
    -m 2048 guix-system-vm-image-1.0.0.x86_64-linux

adding and removing net flags, enabling and disabling kvm. Since I am
not a Qemu expert, let alone a VM guy, I have really no idea what the
-net options for example do.

Could someone give me a hint what I should try/read to get a working
state?

Can you give the exact command line you used to launch QEMU when it did
not work?

I tested the official Guix QEMU image [0] using the instructions in our
manual section Running Guix in a Virtual Machine [1] and I could
successfully do `guix download http://example.com`.

Note that `ping` (ICMP) does not work in QEMU when using '-net user'.
So, don't use `ping` to test the network in QEMU. Use `guix download`
instead since that will always be available.

If it still doesn't work after following the instructions in the manual,
please let us know the results of `qemu-system-x86_64 --version` and
`uname -a`. Also let us know if you are using a firewall or anything
like that.

Happy to help,
Leo
