When upgrading to 2.6.18-1.2798.fc6xen on my dom0, I ended up with a broken ethernet setup because the 8139cp module failed to drive the card. modprobe.conf contained: alias dev1804289383 8139too alias eth1 e1000 I dont remember if I put that in a long long long time ago, or wether it magically got put in there on install. But I had an eth0 and an eth1, of which eth1 was not in use. Changing dev1804289383 to eth0 did not help. I did not really care, so I just switched the cable to the other ethernet port. My dom0 had connectivity, but all connectivity on my xenu's was broken. I think this has to do with the bridge setup. Rebooting did not help either. So I think that apart from the kernel bug in the 8139cp driver, the fedora bridge setup for xen might assume eth0 exists, or won't look further if eth0 is not found? I did not pursue this bug further to actually find out what happens exactly, since I don't have time for that now. I did want to report it, in case someone else runs into the same issue. At least google will find this entry then. Paul -- Fedora-xen mailing list Fedora-xen@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-xen
