Hi Steve,
I'm using a mac mini i7, but not directly. I've installed the Free virtualization suite from vMware vSphere 5.1. There is a Prepackaged ISO that will recognize all hardware (including the secondary Gigabit adapter!). For best performance i'm using iSCSI to a QNAP NAS as HDD for the virtual machines.
I've connected the URI directly to the virtual machine and so far seems to work fine.
This gives you the possibility to manage multiple allstar nodes and, with the two network cards, to use a firewall as well (i'm using Astaro VM image for this, it has a licence you can register for free, for home use)
