Stephen, Kernel is 2.6.16-1.2080_FC5.xenU I've found that the problem was caused because the 2.4 based guest OS (White Box Linux) didn't support modprobe.conf so didn't load the CONFIG_XEN_NETDEV_FRONTEND Module. I've recompiled the kernel so that this module is built in and it resolved the issue. Thanks for your reply, Duncan -----Original Message----- From: Stephen C.

Which domU kernel? If it's not a recent (post-Xen-3.0.0) one, you may be out of luck: XenSource changed the domU ABI before the final 3.0.0 release. --Stephen
