hi, I happened to get a "emulation fail" when running the following command:

The version of kvm I used for kvm module is "694401697ccd822bb08019731c3ee1bb34323d8e" and the kvm-userspace is "a57b838b49bc4e4e7439b18d0323385d53e41c7f". // Not sure if this is the right way to show the version I am using. If not, please correct me, this is the first time I am using git... Anyway, I really want to get some comments about how to trace this problem and would be very glad to dig into it! Thanks, Neo -- I would remember that if researchers were not ambitious probably today we haven't the technology we are using! ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
