I get the flexibility that gives you, but in that instance you've evidently got a 32GB machine sitting there, unused. For my money it's just as valid to move their guest to the 32GB machine, balloon up to allocate the space and allow the guest to use the extra space as disc cache as required, then balloon down afterwards and migrate off as normal.
True, but then the live-migrate feature would not be possible. Also, even in Xen, the ballooning can only be done in a range (I think not quite 4 times), so you can't set up 1GB and then balloon to 28GB, then go down to 1GB again.

Why not?
