[Qemu-devel] trace an incoming network packet of data ?

[S.P.T.Krishnan]

Hi,

I would like to know how a network packet of data is received by qemu
and delivered to the guest OS ?

I need to debug/print the incoming data at the qemu-level before it
reaches the guest OS.
Can you give me a few hints at what files and structs should I be
spending some time on ?

I saw vl.c to be of some importance along with /hw/ne2000.c which
emulates the network card.  However, I want to know the method
(flow-chart ?) which qemu uses to interact with the host OS and
transfers the packets of data to the guest OS ?

Many thanks in advance for your time.

regards,
Krishnan

Hi,
I am interesting to understand qemu network manage too. I search and find
this document:
http://www.h7.dion.ne.jp/~qemu-win/HowToNetwork-en.html
Look if it can help you (I read it very fast but I think it's very
interesting).
