web.cs.wpi.eduIn a Virtual Machine - each process "seems" to execute on its own processor with its own memory, devices, etc. • The resources of the physical machine are shared. Virtual devices are sliced out of the physical ones. Virtual disks are subsets of physical ones. • Useful for running different OS simultaneously on the same machine.
