Hi! You can take this question to the users mailinglist from CloudStack which can be found

> Currently a address is used for communication between the (KVM) hypervisor
and a System VM.
> The address is provided through a socket to the SSVM on startup.
> This adds additional complexity since such an address needs to be recorded in the database.
> IPv6 provides the Link-Local address starting with fe80:: where it is calculated based
on the MAC-address.
> This address could be used to communicate with the SSVM without any prior communication
with it. The Hypervisor knows the MAC address of the SSVM and thus it knows which address
the SSVM will obtain.
> On this address a provisioning daemon could run instead of the current 'patch via socket'
> Over this address the SSVM could even expose a complete REST-full API which can be used
to talk to the SSVM.
> Using the IPv6 link-local address would be the first step to IPv6 in the SSVM.
