Having worked _briefly_ with elf coredumps as a starting point for process checkpointing, I don't think they would be well suited for this. An elf coredump defines all of a running applications mappings in the program header. In a VM, there will be MANY mappings, which may be fragmented, corresponding to many page directory pointers. If all I cared about were the kernel state, that would be fine, but I think users would like to be able to see what processes were doing at the time. Examining the user-state will of course be very OS-specific. Nonetheless, I think that it is important that the information be there, so that if someone does choose to develop the tool, the pieces will already be there. Any corrections or contrary opinions are welcome ... -Kip ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
