Slightly of topic: I won't be surprised if one actually come out with a solution similar to L1, L2 etc caches in CPU vs.outside RAM. CPU cache is namelly several times faster tham RAM. While mechanical disks were several 1000 times slower than RAM. Until now when SSDs are aproaching the speed of RAM.
Conclusion? Why RAM won't be just a L3 cache in a whole hiearchy of caching from SSD up to CPU? Automatic, supported by OS or even hardware, as CPU caches are? Then image wont be needed to be read to RAM and snapshoted back to disk, it can be run directly from disk.
