Patent ID: 7539986

Claim:
A method comprising: performing a file system integrity validation on a host machine having a hypervisor architecture when a file system of a second process is mounted on a file system of a first process, wherein the file system integrity validation occurs independently of booting the host machine and includes determining if a time period has elapsed if the first process traps an event causing the first process to exit into a virtual machine monitor process; determining whether it is safe to remap access to the second process by a resource; scheduling the first process and the second process to run on the host machine if it is determined not safe to remap resource access to the second process, and if it is determined safe to remap resource access to the second process: remapping resource access to the second process, scheduling the first process to run on the host machine, and remapping resource access to the first process; and outputting a result of the file system integrity validation on the host machine.
