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?
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.
