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