I put one of our blades in maintenance mode and all guest machines were migrated to other hosts in the cluster using live migration. However, some users that have desktop redirection and running network-sensitive applications lost the connections with the applications running on one of the guests.
Checking the server involved, I see about 20 occurences of Event ID 2012: "While transmitting or receiving data, the service encountered a network error." There are more of these scattered about in the system log, but not in a group like this. There aer no other errors in the logs at the time the server was put in maintenance mode.
I thought live migration was supposed to be seamless. Is there something else we can do to ensure proper load balancing on our hyper-v cluster without connections being dropped?
