-config FILE
- bool "Host Support for file operations"
- default n
- help
- Select this if your host OS supports file operatoins and you want Palacios to be able to use them.
-
-config KEYED_STREAMS
- bool "Host support for keyed streams"
- default n
- help
- Select this if your host OS supports keyed streams
- Palacios Checkpoint/Restore and Migration depends on this feature
-
-config CONSOLE
- bool "Host Support for VM text-mode console"
- default n
- help
- Select this if you want to forward a guest console interface to some host OS service
- This is for a TEXT MODE console. Select the framebuffer console for graphics and text
-
-config GRAPHICS_CONSOLE
- bool "Host Support for VM graphics and text-mode console based on a frame buffer"
- default n
- help
- Select this if you want to forward a guest graphics-mode (and text-mode) console
- interface to some host OS service. This is for a GRAPHICS console based on a shared frame buffer.
- Text mode output is RENDERED onto the framebuffer
-
-config SOCKET
- bool "Host support for Network Sockets"
- default y
- help
- Select this if you host OS implements a socket API that is available to Palacios. This is required
- to support the internal networking features of Palacios.

-config PACKET
- bool "Host support for Raw Packet Transmision"
- depends on EXPERIMENTAL
- default n
- help
- Select this if you host OS implements a raw packet network API that is available to Palacios. This is required
- to support the internal networking features of Palacios.
