[Fedora-xen] Changing CDS

[Reed, Tameika N]

Here is how I did when doing fully virtualized

1.	First find out where the iso is mounted :
a.	Xm block-list domain-name

This should return something similar to following:

Vdev	BE	Handle	state	evt-ch 	ring-ref	BE-path
768	0	0	1	-1	-2
/local/domain/0/backend/vbd/8/768
5632	0	0	1	-1	-1
/local/domain/0/backend/vbd/8/5632

2.	Now after finding that out do the following:

Xenstore-read /local/domain/0/backend/vbd/8/5632/params

This should return:
/root/rhel-5-server-i386-disc1.iso or wherever your isos are stored

3.	Now can do the following to change which iso should be read:

Xenstore-read /local/domain/0/backend/vbd/8/5632/params
/root/rhel-5-server-i386-disc2.iso
