Hi Yevgeny,

a few comments:

1. I'm missing mockups for the UI changes.
2. I'm missing description of the changes in the system behaviour -
 - A new cluster is added to the DC, what happens? ovirtmgmt used to be
attached to it by default, now each cluster can have a different network
as management network....
- Why do we create a new network by default? Is it still needed?
- What happens when the management network becomes unavailable on a
host? currently we loose connectivity with the host, can we do better?
- What limitations come with the role of management network? For example
currently the management network can not be deleted, now it can't be
detached, network must be mandatory (vs optional) etc.
- User should not be able adding a host to the cluster before there is a
network with the mgmt role.

3. The high level feature page should be used for describing the system
behaviour and the detailed user page for implementation changes.


Thanks, Livnat
