Thanks for your reply.
In xen I always used the vnc automatic port selection, which use the 
qemu's auto port selection.
Now I'm switching from vnc to spice on xen production systems, and I 
need an automatic port selection like vnc.
I believe that lot of xen users will like this feature and part of them 
still stuck on vnc due to the lack of it.
Could any one help to add this feature?
Why not implement it on libxl? (awaiting xen-devel feedback)

Thanks for any reply.
