I think Avi meant using a virtual bus as an option for HVMs too (windows especially). Currently we're using the cpi bus. Using a new virtualized bus might be a good idea, it's easy & clean for open source. The question is it make life easier for HVMs. For instance, on windows we'll need Pnp support for these devices. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
