Hi, everyone When I run QEMU on Dom0, I can use TAP device to set up networking for its guest. For example, I use OpenVPN to control the TAP device tap0 and setup its IP address. *$ openvpn --mktun --dev tap0 --user `id -un`* *$ ifconfig tap0 192.168.50.193 netmask 255.255.255.0 up* I use QEMU''s offical ARM test kernel and initrd disk image ( arm-test-0.2.tar.gz <http://wiki.qemu.org/download/arm-test-0.2.tar.gz>) to execute QEMU and use tap0. *$ qemu-system-arm -kernel zImage.integrator -initrd arm_root.img -net nic -net tap,ifname=tap0,script=no,downscript=no* Then I change QEMU''s guest IP address to 192.168.50.194, after that, I can ping host or TAP device from QEMU''s guest. But when I perform the above steps on PV DomU, I can''t ping host or TAP device. I tried to compile TAP device into kernel or as module, but none of them works. Does anyone have the same problem? Any suggestions will be greatly appreciated, thanks in advance. -- Best regards, Yao-Jing Wen _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
