Public bug reported:
Currently the default installation of UEC restricts the number of VMs
based on the lower of memory and core numbers retrieved from the node
controllers.
There should be an option in the visual interface to allow a cluster to
overcommit on CPU. Ordinarily when you're providing VMs on a cluster
memory is the only restricting factor you require - kvm does a good job
of sharing out processor power. CPU cores should be the number of cores
available to the instance rather than dedicated to it.
The workaround at the moment appears to be increasing MAX_CPUS to a
large value in the cluster controller.
