2 bool "Xen memory balloon driver"
3 depends on XEN
4 default y
5 help
6 The balloon driver allows the Xen domain to request more memory from
7 the system to expand the domain's memory allocation, or alternatively
8 return unneeded memory to the system.

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

24 default y
25 help
26 The xen filesystem provides a way for domains to share
27 information with each other and with the hypervisor.
28 For example, by reading and writing the "xenbus" file, guests
29 may pass arbitrary information to the initial domain.
30 If in doubt, say yes.

35 default y
36 help
37 The old xenstore userspace tools expect to find "xenbus"
38 under /proc/xen, but "xenbus" is now found at the root of the
39 xenfs filesystem. Selecting this causes the kernel to create
Matt LaPlante692105b2009-01-26 11:12:25 +010040 the compatibility mount point /proc/xen if it is running on
Alex Zeffertt1107ba82009-01-07 18:07:11 -080041 a xen platform.
