Rename the tap connection to "mytap" and set the IP to 192.168.1.1 (or any ip) 2) use any QEMU 0.12.X and issue the following command c:\qemu> qemu -net nic -net tap,ifname=mytap -cdrom ../linux.iso 3) Inside linux guest system, set the ip of the nic # ifconfig eth0 192.168.1.2 4) In the windows host try to ping the linux guest (or the other way around, after you disable the windows firewall) c:\qemu> ping 192.168.1.2 Pinging 192.168.1.2 with 32 bytes of data: Reply from 192.168.1.1: Destination host unreachable. Those above steps is not working on QEMU 0.12.X. But confirmed working (ping successful) on: - QEMU 0.9.X - QEMU 0.10.X - QEMU 0.11.X I have tried with windows XP and windows 7 host system. I haven't tried the qemu latest from git repository, but looking at the "net /tap-win32.c" revision date, I guess the bug has been around for a while. Thanks.
