The balloon driver allows the Xen domain to request more memory from
|
|
the system to expand the domain's memory allocation, or alternatively
|
|
return unneeded memory to the system.

Scrub pages before returning them to the system for reuse by
|
|
other domains. This makes sure that any confidential data
|
|
is not accidentally visible to other domains. Is it more
|
|
secure, but slightly less efficient.
|
|
If in doubt, say yes.
