nic e1000 network interface does not work with 32-bit windows 2003r2 with sp2 nic e1000 network interface does not work with win2k3r2 32bit e1000 driver in win2k3r2 32bit seems to be broken. The interface is able to receive ip from the dhcp server, but not able to ping it from any linux guest or host, but was able to ping it from windows guest. Running network test, netperf, between the windows guest fails with the message "netperf: receive_response: no response received. errno 104 counter 0" cmdline used: /usr/local/bin/qemu-system-x86_64 -drive file=win2003r2sp2-32.raw,boot=on -net nic,vlan=0,macaddr=20:20:20:00:00:04,model=e1000 -net tap,vlan=0,script=/home/yogi/qemu-ifup -m 2048 -enable-kvm -usbdevice tablet -vnc :1 uname -a Linux bc1cn9 2.6.30.9-96.fc11.x86_64 #1 SMP Wed Nov 4 00:02:04 EST 2009 x86_64 x86_64 x86_64 GNU/Linux Distro: fedora 11 Thx yogi Maybe you can try the e1000 drivers from Intel's site. You could also try using the stadard Qemu mac prefix of 52:54 (the first bit of the mac has a special meaning). I can reproduce this in qemu-kvm 0.12.50. Most likely a problem with the e1000 driver in QEMU. Funny thing is the guest seems to be able to obtain it's IP address via DHCP, then stops communicating. Can you still reproduce this issue with the latest version of QEMU? [Expired for QEMU because there has been no activity for 60 days.]
