Thanks for the assistance Chris -- I think I've tracked this issue down to bug: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=202182 Kernel version is kernel-2.6.17-1.2174_FC5xen (or xen0) xen version is xen-3.0.2-3.FC5 I'll try building netloop, netbk and blkbk statically into the kernel, rather than as modules and see if that fixes it. As it sits, it doesn't appear the current kernel/xen rpms work together. I get both the "no veth0" error or the kernel panic, depending on whether its the PAE kernel or not. Does this sound like the same issue to you? -- Fedora-xen mailing list Fedora-xen@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-xen
