Subject: [PATCH] Use vga command line for passthrough, disable aio.

Note:  With this change, it is recommended that vga=passthrough option be used in xenvm config
file instead of vga_passthrough=1 although the latter option is available at the moment for backward
compatibility but will be deprecated in future.
