Ravi, please take a look how we can make such errors more understandable to users
Comment 2 Ravi Nori 2016-09-08 14:40:28 UTC 
When exception message is null the code uses the root cause resulting in the message seen above.

Pushed a patch to add more debug log messages when such a situation occurs so the user can debug the issue using the stacktrace in the logs.
Comment 3 Sandro Bonazzola 2016-12-12 13:56:21 UTC 
The fix for this issue should be included in oVirt 4.1.0 beta 1 released on December 1st. If not included please move back to modified.
Comment 4 Jiri Belka 2017-02-01 10:54:55 UTC 
Are there any user-doable reproduceable steps withough modifying the code? Thx.
Comment 5 Ravi Nori 2017-02-07 13:49:33 UTC 
Turning of a host should be sufficient to verify this BZ. In the logs UnresolvedAddressException should no longer appear for the host when Upgrade check is invoked. Instead there should be additional messages in the debug log about the exception.
Comment 6 Jiri Belka 2017-02-08 15:50:51 UTC 
ok, based on descr in #5
