6 	bool "Xen memory balloon driver"
9 	  The balloon driver allows the Xen domain to request more memory from
10 	  the system to expand the domain's memory allocation, or alternatively
11 	  return unneeded memory to the system.
14 	bool "Memory hotplug support for Xen balloon driver"
17 	  Memory hotplug support for Xen balloon driver allows expanding memory
22 	  Memory could be hotplugged in following steps:
24 	    1) target domain: ensure that memory auto online policy is in

29 	       where <maxmem> is >= requested memory size,
31 	    3) control domain: xl mem-set <target-domain> <memory>
32 	       where <memory> is requested memory size; alternatively memory
38 	  Alternatively, if memory auto onlining was not requested at step 1
