| bool "Xen memory balloon driver" |
| 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. |
| bool "Scrub pages before returning them to 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. |
| tristate "Xen filesystem" |
| 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. |
| bool "Create compatibility mount point /proc/xen" |
| 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 |
