I don't know much about tmem systems, but isn't there some daemon required in the guest to achieve that? Or perhaps that is what CONFIG_XEN_SELFBALLOONING in the domU config is for? Is that enabled along with things like FRONTSWAP and friends? Some more details of exactly what you've added to which command lines and some logs might allow someone to spot where things are not correct. Ian.
