Version of LivePC

hi,

I have a LivePC running on my LAN. I have 4 machines connected. One of the machine acts as a server. How do i get to know what version of the LivePC am i running on the client side ? also the updates made by me on the server side are not getting reflected on the client. I also need to know about the default version being specified in vm.xml.
Please help me out

Regards
