I'm having trouble with the bridged network setup. I'm new to kvm, but I got a window xp sp2 guest set up without trouble a few days ago. I followed the instructions in the RH virtualization guide, and all was fine until I had to reboot the host machine a few days later.
Then, I lost networking altogether on the host machine. I lost track of all the things I tried, but finally got networking back on the host, but I suspect it's not right.
For one thing, I deleted ifcfg-br0. Also, I commented out bridge=br0 in ifcfg-eth0. Oddly, ifconfig shows both interfaces, and shows them both set to static ip.
One of the points I'm confused about is what, if anything, to write for the ip address in ifcfg-eth0.
When I first set it up, I set the bridge interface to dhcp, and kept the host as a static ip on my lan. That made made the host dhcp, but that's no good for me, so I set the ip in ifcfg-br0 to my static ip, and everything worked fine, even though it didn't make sense that both eth0 and br0 had the same ip.
Thanks for any guidance.
