 A domain with a weight of 512 will get twice as much CPU as a domain
 with a weight of 256 on a contended host. Legal weights range from 1
 to 65535 and the default is 256.

 The cap optionally fixes the maximum amount of CPU a domain will be
 able to consume, even if the host system has idle CPU cycles. The cap
