@bkhizgiy hi,
a. do you know how the "rootDisk" parameter will be used ?
( for example, is it going to be a number e.g. "1" - first disk (default) "2" - second disk ? )
b. do you plan it to be a plan thing, e.g. all the vms will have the same rootDisk value ?

@bkhizgiy hi,
it's going to be a vsphere only ?

@yaacov Hi, we just had this conversation yesterday:) I'm still thinking about the best way for the user to specify this property. We were considering passing a number like you suggested; I just need to check if it can be processed correctly in the backend. I'll update here once we have a final conclusion.

And no, I think it should be applicable for OVA as well. From virt-v2v, I saw it's possible to do in OVA conversions as well, so I think we should support all flows.
