Hello, everyone!
Sorry for the inconvenience, but as a part of my diploma thesis, I am
creating a virtual NIC for QEMU, in order to support a new cluster OS
of the university. (Saving the overhead caused by emulating real
hardware, it is not emulating an existing NIC.) Anyway, now it seems
to be working correctly, except for handling jumbo frames, which I
have to make available.
I connected two QEMU instances by -net socket,listen and -net
socket,connect options and I can send and receive packets in the
guests. If I'm sending a 9000 byte packet, or bigger than 4 kByte, it
is received completely by the other instance, but then QEMU crashes.
I didn't find an according bug in the code of my NIC.
MTU of 127.0.0.1 is 16436...
Is there something special that I have to take care of, dealing with
jumbo frames? Unfortunately I'm no expert in networking...
Thank you in advance!
Regards,
Martin Rauh.
