Re: [Xen-devel] Xen 3.0.4 - Ballooning
Not such a dumb question. As far as I know, memory ballooning is only
done from the control partition (dom0) nowadays, explicitly.
It would be nice for something inside of a domU's kernel or userspace to
watch
some metric and then ask nicely for more memory if needed. Paravirtual
drivers
can do this for sure, but I haven't poked around enough to know which
available
ones do and how to trigger it.
Peace.
