But with the ability to create a template with disk 1 on SD1 and disk2 on SD2 is that
still a compelling feature?
yes, since I may want to create virtual machines from this template
where the 2nd disk is sometimes on SD1 and sometime on SD2 (just like
today, where i can instantiate a VM from the template on multiple
storage domains)
The new feature will just allow me to not clone all the disks of the
template to all storage domains, rather a subset.
