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

secure, but slightly less efficient.

The xen filesystem provides a way for domains to share
|
|
|
|
|
information with each other and with the hypervisor.
|
|
|
|
|
For example, by reading and writing the "xenbus" file, guests
|
|
|
|
|
may pass arbitrary information to the initial domain.

|

If in doubt, say yes.
