Hi, I have no network access when I boot into my Xen kernel under FC6. Everything to this point is the default configuration and xend-config.sxp looks ok. After Xen boots, I run /sbin/ifconfig and I see ''lo'' and ''xenbr0'' but no vifs. I read in the Xen manual how eth0 is moved on the xenbr0 - is there anyway to diagnose if there is an error occurring? I use dhcp to acquire my IP if that helps. Any comment or pointers are welcome. Thanks very much, Cam

I can see 4 veth/vif0 interfaces, but they''re all down. I get the error "SIOCSIFNAME: No such device" when I run /etc/xen/scripts/network-bridge start Do you have any thoughts? Thanks, Cam
