BVT scheduler settings

MARC: msg ‘Re: [Xen-devel] BVT scheduler settings examples’:

xm bvt takes the following arguments:
DOM – domain id
MCUADV – inverse of weight. Therefore if you want to give more CPU decrease MCUADV

WARPBACK – boolean, enables domain to execute before other domains after waking up, decreases lattency, useful for driver domains
WARPVALUE – the bigger the value the greater number of domais will be preempted
WARPL – if warpback is enabled, limit the time that it is enabled for
WARPU – after warping was disabled by WARPL enable it again after WAPRU

So if you want 30/70 you can do the following:
xm bvt 1 47 0 0 0 0
xm bvt 2 20 0 0 0 0
(since 47/20 ~= 2.33 and 70/30=2.33) the MCUADV is integer, so in order to increase the granurality you can give bigger values. Only the relative value matters.
