anti-affinity: what're the mechanics?

Hey, all.  Turns out we really need anti-affinity running on our (very 
freaking old -- Juno) clouds.  I'm trying to find docs that describe its 
functionality, and am failing.  If I enable it, and (say) have 10 
hypervisors, and 12 VMs to fire off, what happens when VM #11 goes to 
fire?  Does it fail, or does the scheduler just continue to at least 
*try* to maintain as few possible on each hypervisor?

Thanks!
