Yeah, for example, VMware Workstation have a feature call snapshot manager,

it can make a snapshot of the VM state online, which don't need to pause the 

service, etc apache Web server maybe.

I think it dumps the memory and CPU state, oh, and of cause the virtual disk.

So, what I curious about, is how about Xen do the similar things.

Thank you for your reply!
