I found this note from RedHat on bugzilla

https://bugzilla.redhat.com/show_bug.cgi?id=1827033

Seems like this could be my issue

This could be where had issue with rebuild of ovirt-engine.  And then had to scrape out the disk files to then import them back in. I then moved the "old files" into sub folder "junk"  ... so after reboot I could know nobody needed them..and delete old orphaned disk from previous oVirt-HCI deploy version.

Got message this AM when tried to login to oVirt Engine which up till now has been working fine.

I can supply username and password and get portal to choose "Administration Portal" or "VM Portal"

I have tested both.. both have same response about java.lang.reflect.UndeclaredThrowableException

I restarted the engine

I downloaded and installed key from portal.. thinking that may have been issue.. it was not.

I googled around /searched forum and nothing jumped out.   (only hit I found in forum https://lists.ovirt.org/pipermail/users/2015-June/033421.html  but no note about fix)
