Please attach logs. Engine as well as VDSM logs from both source and destination.

I assume you've looked into possible DNS issues (for example, the destination having multiple records in DNS, some which are wrong), firewall, routing, etc.

I see couple of "java.net.NoRouteToHostException: No route to host" and "Caused by: java.rmi.ConnectException: Connection timeout" in the logs which looks like some network issues.

Can you please make sure the connection between the two hosts is indeed working when trying to migrate?

Comment 7 Tomas Jelinek 2016-03-09 08:17:34 UTC

yes, something like:
telnet hostB <port>

e.g. with default port:
telnet hostB 54321

The particular port you can find in vdsm.conf as management_port.

So, closing this BZ as "not a bug", since it seems it was a networking issue.
In case it will start happening again and the networking would be OK, please feel free to reopen.
