There is no such thing as a standard template. Your template is no
different than the templates that are included with XCP.

A template is just a VM with the is-a-template flag set to true. That's
it, nothing special. It can have VDIs attached to it too.

When you install a VM, the template is cloned, and the is-template flag
is set to false. If there is a 'disks' key in the other-config, then
vm-install will create disks as specified. If the template has VDIs
attached, then those will be copied at attached to the new VM.

You already have, it seems. Try doing 'xe vm-install
template=model-wheezy-32bit new-name-label=i-hope-this-works'.

As I said before, there is only one type of template, and that is just a
VM with the is-a-template key set to true. Hope this helps,

Mike
