<div>Has anyone used this? If I am reading it correctly this scheduler limits the number of virtual cpus on a host to max_cores (from nova.conf on the head node) times the number of cores on the host. So, if I want one virtual core for each real core I can
use this scheduler and set "max_cores = 1" on the head node. </div>
<div><br>
</div>
<div>Is this correct? If this is correct I will try this out in the next day or so.</div>

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>
