If it's not used then it will probably get moved into swap eventually.

Are you sure about that?

I suspect that the combined overhead of running multiple instances
of your OS in multiple virtual machines will not come close to the
memory saved by KSM.

KSM is very bleeding-edge - good luck find a distro (or even a stable
kernel) that supports it.

It also complicates things greatly by having many more machines to
look after.
