We already have a balloon driver, however it is not yet ready for 
inclusion.  Perhaps Dor will comment.   Swapping is some way off; there 
is a fairly complete patch from Shaohua Li that does this, but it 
requires kernel changes and we are investigating other approaches.

Yes, when swapping is implemented then guest memory will be swapped to 
the host swap.  Of course, if the guest has its own swap file, then it 
will swap to the guest's swap independently.

Yes.
