For Qemu it would be desirable if the same interface would be used as with plain KVM as far as possible. Comparing Luvalley version of Qemu to released version, the changes seem to be quick hacks with a lot of "#if 0". I guess KVM changes are more radical. -- http://www.hailfinger.org/ -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
