Once we start using Nix fixtures, guest processes output will be also part of console output so it will be easier to see what's going on inside the guest.

Doesn't seem to work with qemu in eugeneia/snabb-nfv-test?

Strange, it worked locally, I'll test again.

@eugeneia I can't reproduce this using Nix toolchain on lugano-3

$ git clone -b refactor/matrix https://github.com/snabblab/snabblab-nixos.git
$ cd snabblab-nixos
$ nix-build jobsets/snabb.nix --arg snabbSrc "builtins.fetchTarball https://github.com/domenkozar/snabbswitch/tarball/qemu-dmesg" -A tests

I'll close the PR and reopen, hopefully that will retrigger SnabbBot build.

I've tested also with qemu 2.4.1, @eugeneia if you find some time to test this locally I'd appreciate it :)

I can't reproduce it either. Reopening does not trigger a SnabbBot build (only new commits), did that now manually.

Edit: for the record, the failure we are talking about is here https://gist.github.com/SnabbBot/3447fc270c52b233ce438a39b9a11b5f

I can reproduce it on davos, seems to be a QEMU bug that is triggered here? Here is the qemu logs:

@eugeneia could you try different qemu version? It does clearly hint to be a qemu bug. I could try 1.4.0 and see if I can reproduce.

@domenkozar The bug isn't triggered in QEMU v2.4.1, I opened #948 to avoid this issue.
