System and method for deploying virtual servers in a hosting system
Some embodiments provide a method for creating an image of a virtual machine. The method identifies a particular computer system operating as a virtual machine with a particular configuration on a hardware resource of a hosting system that includes several hardware resources. The method captures data representing the particular computer system. Capturing the data includes copying a particular section of the data, computing a checksum for the particular section of the data, and streaming the particular section with the computed checksum to a storage.
