Source: ganeti Version: 2.16.0-5 Severity: important Dear Maintainer,
using virtio-net multiqueue support with ganeti on buster is broken in a way to be unusable. Its current code leads to generating one tap device per queue - instead of one tap device that handles the multiple queues. As such one can not currently use it, and is limited to just one queue, which can drastically limit the possible network speed. (Yes, its broken ONLY when using multiqueue, hence no grave or something. Plain singlequeue works fine. Still, it limits it a lot, so important) The fix is simple and ought to be fine for a stable update, it can be found in https://github.com/ganeti/ganeti/pull/1326 - its basically 6 lines of changes and 6 new lines added in ganetis code. -- bye, Joerg
