Hi to all. I'd like to implement a little virtual network using QEMU 0.10.2, but, = until now, I have failed. This is the situation. Host: AMD 64 running FreeBSD 7.2 #ifconfig nfe0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu = 1500 options=3D10b<RXCSUM,TXCSUM,VLAN_MTU,TSO4> ether 00:15:f2:44:2d:f9 inet 192.168.0.2 netmask 0xffffff00 broadcast 192.168.0.255 media: Ethernet autoselect (100baseTX <full-duplex>) status: active plip0: flags=3D108810<POINTOPOINT,SIMPLEX,MULTICAST,NEEDSGIANT> metric 0 = mtu 1500 lo0: flags=3D8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3=20 inet6 ::1 prefixlen 128=20 inet 127.0.0.1 netmask 0xff000000=20 I've create an image using the FreeBSD 7.2 DVD: #qemu-img create -f qcow2 hda fbsd72.img 10G The image has been created. #qemu -L /usr/local/share/qemu/ -cdrom /dev/acd0 -m 512 -boot d = fbsd72.img Alfter a long time, the installation of the guest system has been = completed. When the installation program asked for information about network = configuration, as a first step, I chose DHCP configuration and, as = usualy, the network has been set like this: IP 10.0.2.15/255.255.255.0 gateway 10.0.2.2 nameserver 10.0.2.3 When the installation of the guest PC was finished, I've copied the = image to pc01.img, to keep the original untouched. After that I've = started qemu like this: #qemu -L /usr/local/share/qemu -localtime -net = nic,macaddr=3D00:15:f2:44:2d:01 -net socket,mcast=3D230.0.0.1:1234 -hda = pc01.img -cdrom /dev/acd0 & but the network in the guest system does not work. ifconfig in the guest system tells: #ifconfig -a ed0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu = 1500 ether 00:15:f2:44:2d:01 media: Ethernet 10baseT/UTP <full-duplex> plip0: ... lo0: ... If I try: #ping 10.0.2.2 (the gateway) all packets are lost. For this reason, I've tryed a static IP = configuration like this: IP 10.0.2.4/255.255.255.0 gateway 10.0.2.2 nameserver 10.0.2.3 but the gateway does not respond. So it is useless to try with a second = guest system. Please help. Sorry for my bad english. Marco
