Our small network is 10.10.11.0/24, gateway 10.10.11.252. dhcp is set up. I'm using virt-manager to install VM's with kvm-qemu on an F14 host - 10.10.11.100. qemu-kvm-0.13.0-0.6.rc1.fc14.x86_64 libvirt-0.8.3-2.fc14.x86_64 I'd like all the VM's to be on the same network as the physical machines with an address range of 10.10.11.110-10.10.11.130. I have virt-net set up. ifconfig on the host: br0 Link encap:Ethernet HWaddr 00:30:67:6A:2C:5E inet addr:10.10.11.100 Bcast:10.10.11.255 Mask:255.255.255.0 inet6 addr: fe80::230:67ff:fe6a:2c5e/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:2792310 errors:0 dropped:0 overruns:0 frame:0 TX packets:4310569 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:571898900 (545.4 MiB) TX bytes:5394989297 (5.0 GiB) eth0 Link encap:Ethernet HWaddr 00:30:67:6A:2C:5E inet6 addr: fe80::230:67ff:fe6a:2c5e/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:2908711 errors:0 dropped:0 overruns:0 frame:0 TX packets:4462246 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:629708224 (600.5 MiB) TX bytes:5402914301 (5.0 GiB) Interrupt:44 Base address:0xe000 lo ......................... virbr0 Link encap:Ethernet HWaddr 00:00:00:00:00:00 inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:219830 errors:0 dropped:0 overruns:0 frame:0 TX packets:640662 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:142081963 (135.4 MiB) TX bytes:777889995 (741.8 MiB) On virt-manager I've tried a "Routed" network, but that doesn't work: libvirtError: internal error Network 10.10.11.1/255.255.255.0 is already in use by interface br0 Can this be done? How? sean
