the principle of the vm snapshot based on qemu-dm
...orry for that...
register_savevm() included in ioemu-qemu-xen/hw/*.c covers various kinds of hardware in order to save the state of current running vm. In this way, the file saved by the cmd of 'xm save domain snapshot.save' is of large size and the operation costs much time. Is there anyelse way to qucikly create a snapshot, such as only saving the memory state(similary with Hibernation) or something else?!
If someone who understands the principle or have the relevant statistics, thanks for sharing.
cheers
bruce
