[Xen-users] XCP 1.1beta - cannot boot from local DVD

["Joe Linoff" <jlinoff@xxxxxxxxxx>]

Hi Folks:

I am trying to install XCP 1.1beta and a single VM on a computer with no
network connections. XCP 1.1 installed just fine but I am having trouble
getting the VM to boot properly from a CentOS 5.5 DVD. 

The first problem was that I could not observe what was happening. Todd
Deshane solved this by showing me how to disable PV VNC and use "xl
console <dom-id>" to connect. That worked perfectly.

The current problem is that during the boot process it tells me that it
does not have a driver for the CD/DVD-ROM but the server boots and
configure properly when I use the CentOS DVD directly instead of trying
to create a VM guest which seems to indicate that it has the proper
drivers.

How can I debug/fix this? 

My guess is that I made some sort of mistake when configuring the CD-ROM
but I am not experienced enough to figure it out. Note that the
DOM0_CD_NAME="SCSI 1:0:0:0" and the DOM0_CD_DEVICE is "1".

Here is the script that I am using for testing. It simply creates a
guest called test01.  

At lines 8-12 it makes the dom0 CD device not bootable. 

At lines 14-17 it adds the CD-ROM to the VM. I have also attached the
console output. 

I got the steps from this URL:
http://www.xen.org/files/XenCloud/guest.pdf (pg 24): "To install a
supported Linux VM from vendor media using the CLI".

What is really strange to me is that it looks like it is recognizing and
reading the DVD because I had several screens of information that
required answers before I got to this point.
