I was having problems with KVM and part of the troubleshooting process got me to try it on SL6, which finally led me to discover that the command line tool generated XML doesn't work as well as the GUI tool for some reason. So there's the possibility that it could be that the definitions created through virsh in 5.6 has the same issues in CentOS 6.
