Hi to all. I'd like to implement a little virtual network using QEMU 0.10.2, but, un= til 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 1= 500 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 inet6 ::1 prefixlen 128 inet 127.0.0.1 netmask 0xff000000 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.im= g Alfter a long time, the installation of the guest system has been complet= ed. When the installation program asked for information about network configu= ration, as a first step, I chose DHCP configuration and, as usualy, the network has be= en 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 starte= d 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 15= 00 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 configurati= on 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 g= uest system. Please help. Sorry for my bad english. Marco
