David,
Link local is so that the management server can talk to them, and the private
(management) address is so they can talk to the management server.
The Virtual Router has no private address so the standard way that CloudStack
management servers talk to all system VMs is via link local.
SSVM and CPVM have a private address and they use this when thy initiate comms
to the management server, using the address specified in the 'host' global
setting' which should be a load balanced ip if you have more than one
management server.
The exception to this is if using VMware which does not have a link local
network, in which case the equivalent VIF on the vm is allocated a private ip
range, but of course basic networking does not work with VMWare so we can
ignore that for now.

Hi,
Why do system VM's on XenServer in a Basic networking zone require a
link-local address AND a private IP from the management range?
