Hello, I'm new to libvirt, but I've looked around the internet for answers to my question with little success. I'd like to have a configuration script do host network integration when starting a virtual machine using virsh. The documentation (http://libvirt.org/formatdomain.html#elementsNICSBridge) suggests that the interface configuration can include a script tag that describes the path to the configuration script. My domain configuration (/etc/libvirt/qemu/test1.xml) includes: <interface type='bridge'> <source bridge='br0'/> <script path='/etc/libvirt/qemu/test1-networking'/> </interface> Unfortunately this value is never used. I'm using: [root@thoroughbred qemu]# rpm -qi libvirt Name : libvirt Relocations: (not relocatable) Version : 0.4.3 Vendor: Fedora Project Release : 1.fc8 Build Date: Fri 13 Jun 2008 03:15:16 AM PDT Looking at the source, the script value is used when 'ethernet' is specified (libvirt-0.4.3/src/qemu_conf.c:2690): case QEMUD_NET_ETHERNET: { char arg[PATH_MAX]; if (snprintf(arg, PATH_MAX-1, "tap,ifname=%s,script=%s,vlan=%d", net->dst.ethernet.ifname, net->dst.ethernet.script, vlan) >= (PATH_MAX-1)) goto error; ADD_ARG_LIT(arg); } However, the script value is not used when 'bridge' or 'network' is specified (libvirt-0.4.3/src/qemu_conf.c:2313): snprintf(tapfdstr, sizeof(tapfdstr), "tap,fd=%d,script=,vlan=%d,ifname=%s", tapfd, vlan, ifname); Is there a way to force libvirt to use the specified script with interface type 'network' or 'bridge'? If not, are there plans in the future to do so? Cheers, Joshua Emele
