Abstract
Embodiments of the present invention are directed to the running of a virtual machine directly from a physical machine using snapshots of the physical machine. In one example, a computer system performs a method for running a virtual machine directly from a physical machine using snapshots of the physical machine. A snapshot component takes a snapshot of the physical system volume while the physical system volume is in an operational state. The virtual machine initializes using the physical system volume snapshot thereby allowing the physical system volume snapshot to be a virtual system volume snapshot representing an initial state of a virtual system volume. The physical system volume snapshot includes instances of all the files within the physical system volume at the time the snapshot was taken.
