Are there any docs on configuring the various schedulers? I'm putting
together a test cloud, and have a variety of different servers.<br>

Correct me if I'm wrong, but this parameter is used by the SimpleScheduler,
so it must be in the configuration file used by nova-scheduler.<br>

Thanks,<br>
<br>
I added this as an option to nova.conf on one of my compute nodes and doesn't
work. Does it need to be set on the scheduler host? if so, is it possible
to set different values for different compute hosts?<br>
