Fast, Lightweight Virtual Machine Checkpointing
Georgia Institute of Technology, Center for Experimental Research in Computer Systems, Atlanta, GA, 2010
Abstract:
Virtual machine checkpoints provide a clean encapsulation
of the full state of an executing system. Due to the
large nature of state involved, the process of VM checkpoints
can be slow and costly. We describe the implementation
of a a fast and lightweight mechanism of VM
checkpointing for the Xen virtualization machine monitor
that utilizes copy-on-write techniques to reduce the
VM’s downtime and performance overhead incurred by
other forms of VM checkpointing.
