Description Nisim Simsolo 2015-12-28 09:17:13 UTC

Description of problem:
In some cases, such as using PPC, the cluster dropbox in the second import dialog will be empty. clicking "ok" in such case leads to webadmin exception.

Version-Release number of selected component (if applicable):
rhevm-3.6.1.3-0.1.el6

How reproducible:
Consistently.

Steps to Reproduce:
1. Browse webadmin UI and navigate to virtual machines tab > import > set VMware parameters and click "load" > select VM to import > click next.
2. See that second import dialog does not shows cluster in cluster dropbox > click ok
3.

Actual results:
Uncaught exception appears on the top of webadmin: 
Uncaught exception occurred. Please try reloading the page. Details: Exception caught: (TypeError) __gwt$exception:..

Expected results:
Exception should not occur, furthermore, when there is no available cluster to import to (such as PPC which is not supported yet) an appropriate message should appear.

Can you follow http://www.ovirt.org/OVirt_Engine_Debug_Obfuscated_UI and get a nicer stack trace?

Comment 3 Nisim Simsolo 2016-01-04 15:48:40 UTC

obfuscated symbol map code:

zab,com.google.gwt.lang.Cast::dynamicCast(Ljava/lang/Object;I)Ljava/lang/Object;,com.google.gwt.lang.Cast,dynamicCast,com/google/gwt/dev/jjs/intrinsic/com/google/gwt/lang/Cast.java,53,0

Comment 4 Martin Betak 2016-02-17 11:55:01 UTC

After some preliminary investigation it seems that we need to filter the list of available data centers in the very first part of the import process to show only those DCs that have hosts capable of V2V. This will prevent getting into further frontend issues in this inconsistent state and among other things would also cover this scenario with PPC only clusters.

Comment 5 meital avital 2016-06-27 14:28:48 UTC

Verified on 3.6.7.4-0.1.el6

When trying to continue to second import dialog, the next "operation canceled" message appears:
"There is no cluster supporting selected VM(s) architecture in selected Data Center"
