Indeed it works with 2.6.27.
BTW, is it possible to "balloon" to a bigger amount of memory that what
was available when the guest started?
Or is it only possible to "shrink" and "grow" within initial memory
available to the guest, but never "grow" beyond it?
For example, if I start a 2.6.27 guest with 256 MB memory on a kvm-83
host, it is not possible to balloon to 300 MB?
