Proxmox 3 + Debian 7 - USe IPv6 for Proxmox interface

Hey,

I'm new to Proxmox and the whole virtualization thing. I managed now to install Proxmox on top of a
Debian Wheezy installation. Now I've got some questions concerning the network-interface config.

I've got two IPv4-Addresses. What I want to do is, to have two virtual systems and each one reachable
via a IPv4 Address. This means, that for the main Server there is no IPv4 left. How can manage this, since
I still have to access the Proxmox interface? Is it possible to use only for the Proxmox Interface a IPv6 address?

Sorry for this question but i cant find any similar post discussing this kind of question.
