From mboxrd@z Thu Jan 1 00:00:00 1970 From: Neil Katin Subject: EDD failing; not finding ide disks Date: Fri, 21 Jan 2005 17:45:38 -0800 Message-ID: Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Return-path: Sender: xen-devel-admin@lists.sourceforge.net Errors-To: xen-devel-admin@lists.sourceforge.net List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , List-Archive: To: xen-devel@lists.sourceforge.net List-Id: xen-devel@lists.xenproject.org I'm a first time xen user, trying to get 2.0.3 up and running for the first time. I've made some progress, but xen doesn't seem to want to discover my ide disks. I built a xen kernel, starting from an existing, known-working config file. I am running linux 2.6.10. The base distribution is gentoo. The hardware is a low end IBM server (xSeries 200). The relevant grub config lines are: title=IBM Gentoo Linux (bzImage) root (hd0,0) kernel /bzImage root=/dev/hda3 title=IBM Gentoo Linux (xen0) root (hd0,0) kernel /xen.gz dom0_mem=131072 noreboot com1=38400,8n1 module /vmlinuz-xen0 root=/dev/hda3 console=ttyS0,38400 The boot fails with this message when booting xen: BIOS EDD facility v0.16 2004-Jun-25, 0 devices found EDD information not available. VFS: Cannot open root device "hda3" or unknown-block(0,0) Please append a correct "root=" boot option (the full serial log is available at http://www.askneil.com/neil/xen/xenboot.txt if anyone wants to see all the info...) When EDD is running in a normal, non-xen kernel it reports: BIOS EDD facility v0.16 2004-Jun-25, 1 devices found Full dmesg output from the working, normal kernel is available at: http://www.askneil.com/neil/xen/normalboot.txt I'm sorry for bothering the list, but I'm trying to figure out what I could be doing wrong that would interfere with EDD, which just makes low level bios calls. In addtion, the "normal" kernel probes all the ide busses and connected drives; none of this output appears in the xen boot listing (but this might just be a difference between console and dmesg outputs...) Thanks in advance for any help folks might have about this... ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
