Does Xen allow something like "memory hotplug" for its guests?

For example, lets says you are running several guests, and would like to start yet another one for a while - but have no free memory left.

So you simply "hotplug remove" memory from a guest that has a lot of free memory left - and start a new guest.

When that new guest is no longer needed, and is stopped, you can "hotplug add" memory to the guest it was previously removed from.

Is it possible with Xen? If not, is such a feature planned?
