There are some issues with it. Last I checked, you can hotplug CPUs,

by the guest to have access to all memory as the driver inside the

handles the memory size. I believe there was work on real memory
hotplug,
but it might be awhile before that makes it to standard guest kernels.
Ah, okay, I didnt know the balloon driver can be fooled like this. I
guess we need to wait for stuff to get fixed first, thanks!
