I spend some time figuring out why my old centos/rhel/fc images I converted for xen didnt have a proper serial console. It turns out they have either a missing or older version of /dev/xvc0. The fix is to make sure the new device eixsts. either in the initrd and/or some other place. Since these older versions of the OS are likely booting with a newer kernel (from your FC6 host), you have a non working udev, so you need to make sure the device exists manually: mknod /dev/xvc0 c 250 187 Be aware that there are many wrong/old google hits on the majore/minors of this. I hope this helps others not waste as much time as me :) Paul -- Fedora-xen mailing list Fedora-xen@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-xen
