[Xen-users] Building domain from scratch

[mick700@xxxxxxxxxxx]

Hi all,

I have been working with VMware for a while but am a newbie in Xen.  I've 
installed xen-3.0 and tested the result with ttylinux successfully.  Now, I am 
trying to build a virtual machine from scratch but kernel panics with the 
following messages when starting new domain:


xentest >xm create -c xm-rhel4

Xm-rhel4 config file looks like this:

xentest >cat xm-rhel4
kernel = "/boot/vmlinuz-2.6-xen"
ramdisk = "/boot/initrd-2.6-xen.img"
memory = 512
name = "rhel4"
vif = [ '' ]
disk = [ 'file:/xm/images/rhel4.img,ioemu:hda,w' ]
cdrom="/xm/iso/redhat/rhel4-d1.iso"
boot='d'
#root = "/dev/hda ro"

Is there a documentation that defines error messages?  Is it possible to build 
a domain from scratch with Xen?


Any help would be appreciated.
