I have domain0 with 2 other virtual machines runnins. dom0, dom1 and dom2 are linux fedora6. I need three network interfaces in dom1 and dom2 so I add something like that vif = [ 'mac=00:16:3e:17:27:05, bridge=xenbr0', 'mac=10:16:3e:17:27:05, bridge=xenbr0', 'mac=20:16:1e:17:27:05, bridge=xenbr0' ] to the configuration files. Into the virtual machines I added to modprobe.conf alias eth0 xennet alias eth1 xennet alias eth2 xennet and I configured the interfaces. I had some problems with an interface in a virtual machine and I did: rmmod xennet because I would to unload and reload the module. This operation crashed the server: dom0, dom1 and dom2 hungs.
