As I read this, I was wondering if Xen has a boot parameter for enabling 
/ disabling hyperthread, ala the "noht" option in linux (in fact, I 
cannot find the noht flag in the Linux 2.6.12 source either)?  However I 
did come across some patches on the xen-changelog archive that refer to 
the noht flag, so it seems it was there at one time.
Thanks,

Pat
