help
Memory hotplug support for Xen balloon driver allows expanding memory
available for the system above limit declared at system startup.
It is very useful on critical systems which require long
run without rebooting.
It's also very useful for non PV domains to obtain unpopulated physical
memory ranges to use in order to map foreign memory or grants.
Memory could be hotplugged in following steps:
1) target domain: ensure that memory auto online policy is in
