Upstream should be fine, except that if you restart Snabb you may also need to restart the VM.

@vmaffione which QEMU version are you using? Currently our CI is [testing interoperability](https://hydra.snabb.co/build/1141006/download/2/report.html#qemu) with several upstream QEMU versions (2.1.3, 2.2.1, 2.3.1, 2.4.1, 2.5.1, 2.6.0, and our patched version) and seeing...

Thanks for the report. I will add the latest QEMU versions to our CI coverage as the first step towards fixing support and ensuring that it works going forwards.

@vmaffione I updated the [list of QEMU versions to test](https://github.com/lukego/snabblab-nixos/blob/fa0dfe8ec44b11e8a36c8e829c3b812d010efda4/lib/software.nix#L100-L110) and the CI is running that now. This triggered around 2500 new test runs that take around one minute each...

(The reason it takes so many tests is that it is checking many permutations of configurations and also software setup inside the guests e.g. many versions of DPDK for the...

One CI extension that we have talked about but never done is to also test the master branches of projects like QEMU and DPDK so that we are aware of...

Odd. The tests [all passed](https://hydra.snabb.co/build/1149642/download/2/report.html#qemu) including with QEMU 2.7.1 and 2.8.0. This is testing with the unmodified sources from the upstream QEMU release tarballs. Here is one randomly chosen set...

Interesting. I don't see anything relevant in the QEMU 2.9.0-rc release notes. I also don't immediately see a reason when browsing the commits to master: ``` qemu$ git log --oneline...

The curious thing is that our CI is testing 9 different versions of QEMU i.e. our old fork + the last 8 major upstream releases without any patches. None of...

@vmaffione It would help if you can verify that the problem happens with a released version of QEMU like 2.8.0. Just to rule out the possibility of interference from a...
