I haven't looked though, so I don't know. I think it's a very interesting idea, but also that more research is needed to determine that the project will not explode in the face. > My understanding is that coreboot/payloads only initialize the CPU, > chipset, memory, buses This is what coreboot does. > and the minimum devices they need for debug and loading and OS. A payload would do this. > It is the OS who recognizes the different possible mouses, vgas, > network cards, etc., the OS loads the appropiate drivers Yes, but if SPICE is not a beast, the driver requirements would be fairly moderate. However it might also be best to go for an existing kernel. Maybe QNX.

This would be in a SPICE payload. > I don't think there's such a thing in coreboot or libpayload.

The local machine with coreboot might not need an OS to talk SPICE, with the remote machine where the VMs are running. > With coreboot you can certainly avoid loading an OS, but then the > payload will have to do all the useful functionality. Also correct, but maybe it isn't too bad! //Peter -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
