    Description

      Based on https://github.com/virtio-win/kvm-guest-drivers-windows/issues/1131 we should try a very recent kernel on our Ubuntu 24.04 hosts. Then enable LSO on windows, and test the network performance. 

      We could also update the host firmware of the network driver which have been held back so far due to problems with windows performance. Let's check if a new kernel fixes anything.
