Well, the limitation is real and some guest-side handling will be
required in case we want to support kexec with ballooning. But as David
validly mentioned "It's the responsibility of the guest to ensure it
either doesn't kexec when it is ballooned or that the kexec kernel can
handle this". Not sure if we can (and need to) do anything hypevisor- or
toolstack-side.

Anyway, I have to address Jan's comments to my v5 series and I wanted to
play with ballooning a bit before sending v6. This work is pending.
