  • List-id: Discussion of API issues surrounding Xen <xen-api.lists.xensource.com>

I am currently working on my graduate paper, and I am trying some research on xen. I have the following scenario and want to discuss with you:
I have two domainU run on Xen., one is a web service server and can provide services for outside, the other is one backup of the first one, but it can not access outside. I want to do the following job: in a period of time, synchronization the two domain, in other words, something like hot backup. So if the first guest is broken down, I can switch to the second guest immediately with little loss.
The question  is whether I could develop a tool with the api Xen provided to do this job and how can I start? Or is there some tool with source code to do this things already? Could you give me some guid?
Thanks and best wishes!
