Hello,

I want to live migrate a vm from one host to another host. Bu I got this

Did you explicitly ask for this port in the domain XML? What does the
<graphics> element in the domain XML look like? In case you explicitly
asked for port 3 I suggest switching to autoport to avoid similar issues
in the future.

The same VNC port is in use at the destination host. Is it possible to 
change port address without rebooting the server?
Yes, you can change the port number while migrating:

- "virsh dumpxml --migratable VM > VM.xml"
- edit VM.xml and change the port number
- add "--xml VM.xml" option to you virsh migrate command
