Despite my best efforts I couldn’t maintain a stable NFS connection for the network share to Unraid. I’ve decided to bag it and try building a Xen hypervisor up from an Ubuntu install. It looks like XenCenter should still be able to manage it so I should be able to take advantage of the slightly more polished GUI. I’m hoping (but not yet sure) that I’ll be able to use Ubuntu’s regular NFS tools to map the shares and I already know that works well with the proper settings. More once I have that working.
