They should be in sync on such important issues like pci slot configuration. Even if QEMU can control the number of slots declared (which it can't easily do), it will be able to do it only on startup (before BIOS runs). The way to have dynamic number of slots may be pci bridge emulation. Not sure what is needed from BIOS for that. -- Gleb. _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/virtualization
