Hi Grant,

It's just counter inutive and unreasonable for me to have a "template" that I have to clone and THEN set kickstart options and stuff before the first start for each and every VM - I want TEMPLATES that already include every information needed that work after just doublecklicking them in XenCenter!.

It does not seem logical to me to have a template - but to have to set installation specific data(ks= ksdevice=)Â for each and every VM *AFTER* creating it from the template everytime but before starting it - This is not good usability in my eyes and also much too complicated to be used for every average user.

When you populate other-config:install-repository only the mirror is known to the installer but nothing of the above - no ksdevice, ks=URL, ... The same - if not even worse applies to debian-preseed installations.

xe vm-param-set uuid=$VMUUID PV-args="ks= ...."

But for PV-args to work you have to use the commandline AFTER starting a VM created from Template - this does not semm to be an intelligent nor usable approach to me - using my approach you create a template supply the information there and just double-click it in XenCenter check "start automatically" and you're done .. This way I'dont have to tell regular users to fiddle with a quite complicated commandline - in order to setup a kickstarted VM!

Anyway - Thanks a lot for sharing your fine tutorial
Cheers

Andreas,

 ÂJust create your own template (cloning) ONCE. Change the data and save it so each time you want to create a new VM you can just do a xe vm-install. This is the beauty of templates actually. Having a template with everything already in it would mean we'd need 40 million different templates for each kickstart file, install repo etc...

If you have needs that my tutorial doesn't address please let me know.

Some people, when confronted with a problem, think "I know, I'll use Windows."Â
Now they have two problems.
