RE: [Qemu-devel] Questions about networking

[Niessen, Peter]

Hello Mulyadi,

thanks, I'll give it a spin. I'm off for the next few days, so I won't have 
results immediately.

Cheers, have a good weekend,

Peter.

Sorry, I took out most of your messages.


IIRC, I once met the same situation too. And it gets worse when using
non TCP transmission (e.g UDP, multicast etc).

So, uhm, perhaps better to use tun/tap and hook them together, maybe
by simply put them all in same network id but separated from host
network device...
