1 Xeno Balloon driver supports two operations:
3 1. Inflating - which means domain giving up pages of mem to xen.
4 2. Deflating - which means reclaiming memory pages from xen.
6 Currently, domain can only claim pages from xen up to the number of
7 previously released ones. This is to change.
9 Example:
11 # balloon inflate 1000
13 Give up 1000 pages to xen.
15 # balloon deflate 1000
17 Claim 1000 pages from xen.
