er, how could we set it from the Xen config side (or any side)? With
Linux, in PV mode Xen just boots the kernel with some params.


I think putting it into the extra="..." line in a xen domain config file works.
I'm using pv-grub, and with that I just add the config options after the kernel
path (e.g., "kernel /boot/kernel/kernel machdep.idle_mwait=0,boot_verbose=1").


Thanks, I've just find it here: http://wiki.freebsd.org/AdrianChadd/XenHackery

It boots fine with machdep.idle_mwait=0
