This is the warning I get when I run a virtual machine made with guix
system vm

I made a a short video, here

bug#29965: Warning: vlan0 is not connected to the host network

I managed to use system vm-image instead of system vm and I have to say it
fares better

I can fiddle with qemu switches and I managed to allow my virtual machine
to reach out on the network,

The machine is faster and less awkard, the terminal background is dark
instead of sun bright

So this bug is not  urgent

But I still think this is a bug. system vm is a Guix feature and the
machine it provides should be able to get on the network, I think

When you run the script created by `guix system vm`, you can add
arguments to QEMU on the command-line. For example,

$ /gnu/store/...-run-vm.sh -net user -net nic,model=virtio

Or even:

$(guix system vm config.scm) -net user -net nic,model=virtio

Ah, this didn't come to my mind !

What' s this ?
What does come out of "$(guix system config.scm)" ?

/gnu/store/...-run-vm.sh comes out of this and replaces $(…) thing.


As I understand from the video you posted at the thread beginning,
produced QEMU virtual machine doesn't have a network connection.

How did you come to this?  "ping" will not work for QEMU machines by
default, but the network should work.  

You could try to open a web-page with a browser or do anything except
programs like "ping" which uses (ICMP protocol).


Oleg.

no, you're right, the network might be working

I should test a browser

It surely works in the vm produced with "guix system vm-image..."

But it may be working with the vm created with "guix system vm" too

Thanks !
