I know. Normally I rsync the old real machines in the loop-mounted 
directorys in the Xen-Host and boot the old operating-systems with the 
Xen-kernel of the guest after i synced the /lib/modules/kernel-xen-foo 
into the guest. Just works fine most of the time except the guest-system 
is to old. But in this case i wanted a shiny new 9.3 directly installed 
in my 10.2-host

I dont understand what u mean. In Xen 3.0.29... there was this option to 
flag one device as cdrom and the set the parameter "boot = 'd'" which 
maked the instance top boot from this device. this doesnt work anymore 
in 3.0.3. As far as my Information is.

We are using Xen 3.0.295... and Xen 3.0.3 in production here in my 
company. I'm installing/spawning maybe 6 to 9 instances a week for the 
last weeks. Actually new ones and also virtualizing old hardware into 
instances to get space in the racks. And the rate is going up ...
Xen ist totally great, but in the Moment it lacks a bit of dokumentation 
it seems to me.
