This patch adds new policies for PCI devices allocation. There are 3
policies:
- legacy - this is the default value and it describes the current nova
behavior. Nova will boot VMs with PCI device if the PCI device is
associated with at least one NUMA node on which the instance should
be booted or there is no information about PCI-NUMA association
- required - nova will boot VMs with PCI devices *only* if at least one
of the VM's NUMA node is associated with these PCI devices.
- preferred - nova will boot VMs using best effort NUMA affinity
