Also see Xen tmem (in drivers/xen). I am also working on a related project called RAMster that uses frontswap. And someone has started code for KVM to work with transcendent memory (including frontswap). But for now zcache is the only non-virtualization in-kernel user for frontswap. Dan P.S. A recent build fix for zcache is necessary for it to work without manual modification to the zcache Makefile.
