Hi, I have an existing fedora14 system with two interfaces and several virtual interfaces (as in eth0:0, etc). They are currently configured to not be controlled by NetworkManager, but just standard network services. I've recently started working with libvirtd, so I also have a virbr0 interface as well that has its own network and is masquerading the networking for the single KVM instance I have running. I would now like to create another instance that is not masqueraded, but instead uses another virtual interface, such as eth0:1, which is an Internet-addressable IP address. When I try to do this, virt-manager seems to still configure it using NAT. I think the right way to do this is to convert the eth* instances to instead use a real bridge, correct? How can I do this? Below is the output from ifconfig on my system: eth0 Link encap:Ethernet HWaddr 40:61:86:4E:84:09 inet addr:XX.195.193.YY Bcast:XX.195.193.YY Mask:255.255.255.248 inet6 addr: fe80::4261:86ff:fe4e:8409/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:204613580 errors:0 dropped:0 overruns:0 frame:0 TX packets:220748087 errors:0 dropped:0 overruns:0 carrier:1 collisions:0 txqueuelen:1000 RX bytes:146443250035 (136.3 GiB) TX bytes:207505258199 (193.2 GiB) Interrupt:42 eth0:0 Link encap:Ethernet HWaddr 40:61:86:4E:84:09 inet addr:XX.195.193.ZZ Bcast:XX.195.193.YY Mask:255.255.255.248 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:42 eth1 Link encap:Ethernet HWaddr 00:0E:0C:3B:36:F4 inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::20e:cff:fe3b:36f4/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:241615579 errors:6 dropped:0 overruns:0 frame:3 TX packets:230218850 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:210464139370 (196.0 GiB) TX bytes:171698241573 (159.9 GiB) eth1:0 Link encap:Ethernet HWaddr 00:0E:0C:3B:36:F4 inet addr:192.168.1.2 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 eth1:1 Link encap:Ethernet HWaddr 00:0E:0C:3B:36:F4 inet addr:192.168.1.100 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:3439643 errors:0 dropped:0 overruns:0 frame:0 TX packets:3439643 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:849466836 (810.1 MiB) TX bytes:849466836 (810.1 MiB) virbr0 Link encap:Ethernet HWaddr 00:00:00:00:00:00 inet addr:192.168.125.1 Bcast:192.168.125.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:16 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:3088 (3.0 KiB) TX bytes:0 (0.0 b) Thanks for any ideas.
