Correct, new URI layout takes effect in oVirt 3.4, not sure about RHEV but =
I think "ovirt-engine" in URI might change there.

I assume the URI layout change BZ [https://bugzilla.redhat.com/961677] will=
 have some release notes attached.

For UI plugins, I was talking with Alon about this, we could promote the us=
e of relative URIs to make UI plugins unaware of absolute URI layout.

For example, in plugin descriptor:

  "url": "plugin/ExamplePlugin/start.html" // relative to WebAdmin base con=
text path, i.e. /ovirt-engine/webadmin

would result in:

  <iframe src=3D"plugin/ExamplePlugin/start.html">

custom content could be added like this:

  api.addMainTab('Example Tab', 'example-tab', 'plugin/ExamplePlugin/tab.ht=
ml');

and any content within the iframe (either start.html or tab.html) could use:

  <script src=3D"dir-relative-to-plugin-resources/custom-script.js">
  <link href=3D"dir-relative-to-plugin-resources/custom-stylesheet.css">

I'll verify this and update the UI plugins wiki accordingly. Should have th=
ought about relative URIs in the first place :)

Right, this is a known issue with dynamic sub tabs. I've created RFE BZ [ht=
tps://bugzilla.redhat.com/1028968] to track this issue.

Thanks for your feedback!
