[libvirt-users] VNC ports

I am needing to explicitly assign VNC ports to my virtual guests so that I can connect to them externally via a VNC client, and not virt-viewer. Since I will have multiple KVM Hosts with access to the same shared storage (to facilitate migrations) I need to ensure I have unique VNC ports assigned to each guest so that I don't overlap somehow.
I had planned to use a range of ports starting at 51000 for this purpose. While it works to assign port 51001, for example, to a guest and connect via my VNC client, when I run 'virsh vncdisplay guestname' it gives me back a different number that is specified in the XML file:
#virsh vncdisplay win2k8guest
:45101
#virsh dumpxml win2k8guest |grep vnc
<graphics type='vnc' port='51001' autoport='no' />
Is there a logical reason for this that I'm not getting? I know when I have the port set to 5907, for example, it returns something expected:
#virsh vncdisplay win2k8guest
:7
But since I am likely going to need a good number of ports, I want to use a non-registered port range. Any insights?
