Hi,
working / worked with VMWare for some time now as professional IT employee and as a user of a XEN server by my VPS vendor. Never worked with Xenserver or XO(A) till now.
At home I have three linux servers on old hardware and was looking for a way to simplify installations and updates and get rid of the old hardware.
Seen the kickstarter project, backed, and got a link 
Last weekend I installed XCP-ng and after 4 attempts (my fault: never use a new server without updating the firmwares) it was working and running. Main repository on the server itself, second one on the NAS and iso-repo on the nas. Installed first Xen Orchestra to install a new VM and then installed XO to use as main console for installation. It was / is not clear for me if this is the right way but it works.
Installed several linux servers for testing and decomissioned the first hardware one after a few hours. I am impressed with the ease of installation and the usage of Xo, also thanks to @DustinB for the install scripts.
Seems that I have now an easy way of getting to know other stuff and playing with os´ses without being kicked around by my wife to remove my machines from the dining table.
Thanks for this project!
