 From http://libvirt.org/formatdomain.html#elementsCharTCP

  <devices>
     <serial type="tcp">
       <source mode="connect" host="0.0.0.0" service="2445"/>
       <protocol type="raw"/>
       <target port="1"/>
     </serial>
   </devices>

(side note, I wonder why the heck we try to connect to 0.0.0.0:2445 in 
the example)

I'd say substitute 0.0.0.0 with the IP address of your mgmt host. And 
use unique port number per domain, otherwise you'd have to pass XML with 
changed/unique port upon migration.
