Trouble with DHCP and GuixSD in a VM

Trouble with DHCP and GuixSD in a VM

Hello everyone,

I am following along with the steps to get GuixSD installed in a VM here https://www.gnu.org/software/guix/manual/guix.html#Installing-GuixSD-in-a-VM and I am stuck on getting the VM to have internet access. It is able to get an ip address but pinging gnu.org or google.com does not work. I am able to ping both from my host machine.

I run qemu with this command

qemu-system-x86_64 -enable-kvm -m 1024 -smp 1 -net user -net nic,model=virtio -boot menu=on -drive file=guixsd.img -drive format=raw,file=guixsd-usb-install-0.13.0.x86_64-linux

I am running
QEMU: 2.7.1
OS: Fedora 25
GuixSD: 0.13

Any help would be appreciated and let me know if more information is needed.

Don't try to use ping (ICMP) to test the network.  Use someting tcp/udp,
wget/ssh for example.

This is only partly correct. ping *may* not be a sufficient network
test, since many systems block ping-requests. But if he is able to ping
both hosts from the host machine, ping is sufficient network test for
within the guest, too.

I recommend `guix download`, since you know for sure that is available.
I recommended this in the manual recently, but I think the VM-related
sections should be reorganized.

To expand on this a little, the default networking mode in Qemu does not
support ICMP (ping). For more information (and ways to enable it), see:

Thank you everyone. I just went ahead and assumed I had internet access and guix init is downloading right now.
