Qemu does not emulate the 440 core, but that's what our KVM code supports. Bamboo is a 440EP reference board, so the Bamboo setup will be useless to qemu until they get 440 support. That said, there are only 2 places that we make KVM-specific calls in this code, and those can easily be protected with "kvm_allowed" checks in the future. -- Hollis Blanchard IBM Linux Technology Center ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
