Hi Frank, Seems that the KVM agent cannot communicate back to the management server.
In agent.properties the ip is specified, which is the "host" global setting. Is this setting set to the right ip address? Did it end up in the agent.properties? Finally, Can the KVM host talk to the management server over port 8250?
