Hello,

I am porting a C application that requires taking a snapshot of memory on the computer you are running.  The original program uses an external PCI card to read the memory and now I am trying to port this to xen.  I want to run the program in the dom0 guest but the memory that it will be taking a snapshot of is the of memory in the domU guest.  I am using the xen hypervisor 3.3.  Is there any specific library or API I can use in C to do this?  The xen api on xensource seems to only talk about xensource never about the hypervisor alone.  Thank you.

Jeff
