The template attributes are sorted in alphabetical order, so you can assume
a fixed order, but you can't be sure about what child elements will be
present since the template may contain anything.
You could however assume the contents if you force the VM creation to be
only done using your OVF to OCA server; or if you limit the VM information
retrieval to work only for VMs created from your code.
And does this hold even for the content of DISK, NIC and
OS?
Even inside each vector attribute, its sub-attributes are ordered
alphabetically.
Common sense says that Ruby should not execute its instruction
out of order, so the order is fixed and some elements may or may
not appear, but the order should not change. Can you confirm
this ?
Yes, after doing some tests it looks to me that the XML is not modified in
any way by Ruby.
Best regards,
Carlos.
