What this means is that virt-manager implements the VNC protocol directly
itself, so there is no need for a separate vncviewer program. The VNC
code is all in the src/vncViewer directory.

Actually the VCPU & memory adjustment is functional now - within certain
constraints. Paravirt guests can have memory & VCPUs adjusted. Fullyvirt
guests cannot have any adjustments. For guests which are not currently
running (ie inactive), memory, max-memory & VCPUs can be adjusted. Hotplug 
of disks & nics is not yet implemented for anything.

Dan.
