Safe Side Effects Commitment for OS-Level Virtualization

A common application of Virtual Machines (VM) is to use and then throw away, basically treating a VM like a completely isolated and disposable entity. The disadvantage of this approach is that if there is no malicious activity, the user has to re-do all of the work in her actual workspace since there is no easy way to commit (i.e., merge) only the benign updates within the VM back to the host environment. In this paper, the authors develop a VM commitment system called Secom to automatically eliminate malicious state changes when merging the contents of an OS-level VM to the host.
