config XEN_BALLOON

bool "Xen memory balloon driver"
|
|
depends on XEN

|

help
|
|
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.

config XEN_SCRUB_PAGES

bool "Scrub pages before returning them to system"

|
help
|
|
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.

tristate "Xen /dev/xen/evtchn device"

|

help
|
|
The evtchn driver allows a userspace process to triger event
|
|
channels and to receive notification of an event channel
|
|
firing.
|
|
If in doubt, say yes.

config XENFS

tristate "Xen filesystem"

depends on XEN
|
|
default y
|
|
help
|
|
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.

config XEN_COMPAT_XENFS

bool "Create compatibility mount point /proc/xen"
|

depends on XENFS
|
|
default y
|
|
help
|
|
The old xenstore userspace tools expect to find "xenbus"
|
|
under /proc/xen, but "xenbus" is now found at the root of the
|
|
xenfs filesystem. Selecting this causes the kernel to create
|
|
the compatibility mount point /proc/xen if it is running on
|
|
a xen platform.
|
|
If in doubt, say yes.

Create entries under /sys/hypervisor describing the Xen

hypervisor environment. When running native or in another

virtual environment, /sys/hypervisor will still be present,

but will have no xen contents. |
