[maybe Tomas/Eldan/Malini can help here as well]

these static widgets (as well as the type ahead list box [1], for example) are part of 
the instance types feature that had its design details published in [2] and [3], and the 
implementation was done according to this design. I don't see any reason to not utilize 
this newly-introduced concept in other side-tab-based dialogs as well, if it makes sense 
(ui consistency considerations are sufficient, IMO, but I could be wrong - maybe it is 
relevant/correct to introduce this new concept only in the VM-like dialogs).

regarding the specific concern about the DC/Cluster values that aren't necessarily relevant 
for each side-tab in the dialog: I agree with that statement, however:

- putting the "Instance Type" drop-down at the top static section is very useful (see [4] 
for explanation), and as the Instance Types list is derived from the selected DC, it makes 
sense (to me) to put the DC in that top static section as well.

- the DC/Cluster are relevant for some of the tabs in the dialog (Host, Resource Allocation?) 
so for consistency-within-the-dialog considerations, it is probably a good idea to simply 
always show these fields within this top static section.

[there is a good chance that I am missing your point here - please correct me if necessary]

[3] http://www.ovirt.org/images/9/9e/Instance_type.pdf

[4] whenever changing the "Instance Type" value, you can automatically see how these changes 
affect the fields in the current tab on which you are standing (e.g. if you are standing on 
the "System" side-tab, you can change the "Instance Type" selected item and immediately see 
the changes within the "System" side-tab contents), and vice-versa: if you are changing a value 
that was originally propagated from the instance-type, you will see the instance-type automatically 
change to "custom"/"not applicable" as a result, so no need to "jump" between side-tabs in order 
to observe these changes.
