Since commit d85c22e44ee4e24f2be19d579ea8fa0066a85fbb, when pulling aggregate tables from fw_cfg, we generate a default type 0 (bios info) structure if one isn't already provided.
This patch enables the "virtual machine" bit within the bios_characteristics_extension_bytes field of the default type 0 structure.

What do you all think, does it make sense to flip on the "virtual machine" bit when generating a default Bios Info (type 0) table to go along with everything else we received via fw_cfg ?
If yes, please apply :)
Thanks, Gabriel
