Re: [Qemu-discuss] no network connection in a windows xp guest

[Thilo Rießner]

Dear Mike,
here is the invoking command:

ps -C qemu-kvm -F
UID        PID  PPID  C    SZ   RSS PSR STIME TTY          TIME CMD
root      8892  8891 11 406759 1093712 0 18:37 pts/0   00:00:20 qemu-kvm -vga 
std -localtime -m 1024 -soundhw ac97 -cdrom /dev/cdrom 
/home/xen/windisk10G.img

it looks like windows sends packages to the vlan, but can't receive the 
answers. Here is a new print of info usernet where windows xp asks for printer 
services on port 1900. There is no answer from the network, because it doesn't 
react on the 10.0.2.255 net. You can also see the bootp-service offered by 
qemu from 10.0.2.2. If I leave the address to the default windows ip 
(169.254.244.101) it gets lots of answers from the real network outside qemu.
