Hi everyone,
I'm not clear about the principle of the vm snapshot based on qemu-dm,
so the following below maybe a joke. Sorry 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
