[Qemu-devel] BSD network

[Taras]

Hello,
Does anyone have networking working in freebsd or netbsd? I'm trying to 
do a netinstall. Using -pci and -user-net both freebsd & netbsd can 
obtain an ip over dhcp. However netbsd doesn't even seem to be able to 
do dns. Freebsd appears to be able to resolve the dns names of the 
servers, but can't login(tcp wont work?).

Both appear to be close to working. Is there anything one has to do to 
get BSDs to use the nic or is this a bug in qemu?

This may be related to the issue covered in the "Overpotimization" 
thread. Please verify if issuing the following command instead of plain 
"make" resolves the problem for you:

make CFLAGS="-O2 -g -Wall -fno-strict-aliasing

On my system compiling qemu with anything other than default cflags 
makes it crash. I  tried the above, and  "-O1".

Using gcc version 3.2.2 (Mandrake Linux 9.1 3.2.2-3mdk)

Sorry Alex,
I meant to sent this email to the list.


looks like nameserver isn't being set properly for some reason
http://glek.net/~taras/netbsd-dhcp.png is what I get over dhcp.
When I set the networking info by hand and try to ping 10.0.2.2 I get
"ne2: remove transmit DMA failed to complete". However see below.

As reported earlier, this doesn't produce a working qemu here
However
make CC="gcc  -fno-strict-aliasing " seems to to make networking work! I
get nice download speeds too.

Thanks a lot,
