ABSTRACT:
Saving state of Random Access Memory (RAM) in use by guest operating system software is accomplished using state saving software that starts a plurality of compression threads for compressing RAM data blocks used by the guest. Each compression thread determines a compression level for a RAM data block based on a size of a queue of data to be written to disk, then compresses the RAM data block, and places the compressed block in the queue.
