that's my preference as well, and the REST API should already do that today:
- get list of ISOs of available in a DC (the one the VM is in)
- ability to change the CD of the VM
Well, and what about the stop/suspend VM for
example, what we have in the menu today?
Also this should be something that the client decide to have or not have?

my preference is to provide the data, not the semantics of the menu.
We should
clarify something here. There are two possibilities who should be responsible for
deciding
what should the foreign menu contain and also what to do if it the item is selected:
1: the client - e.g. we will not provide any support for the menu in REST because the
client reads what needs
and knows how to call the oVirt back
2: the server side - e.g. we will provide in REST side the menu structure with the
description what to do if something is
selected
Both have some advantages and disadvantages but we need to clarify which way to go. So,
who is the one responsible to decide
what is in the foreign menu (now or in the future) and how to react if something is
selected? Client or engine?
iiuc, we are on the same page.
