This isn't going to work in the near future, because KVM today requires a 440 host, and qemu today doesn't emulate 440 instructions. > Even if I don't run it, it's a much better > build-time environment.

Building would be better done with a cross-compiler than inside qemu. -- Hollis Blanchard IBM Linux Technology Center ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
