Is it similarly easy to run a program that loops back all received packets on a virtio-net port?

I can take a look at cooking up a reproducible test case if you can post for me source location and build instructions for all the relevant components. Just needs...

Thanks, that sounds doable. I will try to make time for this during the week.

My view is that the host side of a Virtio-net interface is extremely complex. We have to deal with every combination of quirks and features desired by the guests. (The...

relatedly: the CI also provides hundreds of machine-hours of testing for each kind of guest and experience suggests that this is necessary for detecting certain classes of bugs. For example...

@vmaffione Could you also tell me which guest kernel version(s) you have seen this problem with? One thing our CI currently lacks is to test many different Linux guests so...

We support both and choose layout based on the features negotiated by the guest.

Good detective work. Could be an issue with multiple memory regions in the map. I have noticed in the past that guests have tended to serve all DMA from the...

Howdy! For the second question - make Snabb run as a bridge between VMs sharing an ixgbe port - check out the [snabbnfv getting started](https://github.com/snabbco/snabb/blob/master/src/program/snabbnfv/doc/getting-started.md). For the first question -...

Have you seen the HOWTO linked above? That goes into a lot of detail about running all the bits including QEMU. For me it is always crafting the QEMU command...
