Allright, I think I got the issue. I am trying to boot a centos 4.1 on a fc6. Now fc6 initrd, even the custom created one, has nash-hotplugd, which has to be killed before starting udev, but this logic is not there in the initscripts of centos-4.1. So I have to basically hand craft an initrd that will kill off this nash-hotplug in the initrd itself, if it has to work with all the older distros. This is too much work, to tell the truth. I will test with fc6 guest on fc6 and report back. -- Fedora-xen mailing list Fedora-xen@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-xen
