Notes for the flowchart on the use of setaffinity for VM.start

In the flowchart, two code paths are set in bold:

• Show the path when Host.numa_affinity_policy is the default (off) in xenopsd.
• Show the default path of xc_vcpu_setaffinity(XEN_VCPUAFFINITY_SOFT) in Xen, when the Domain’s auto_node_affinity flag is enabled (default) to show how it changes to the vCPU affinity update the domain’s node_affinity in this default case as well.

xenguest uses the Xenstore to read the static domain configuration that it needs reads to build the domain.
