Implemented as setting NUMA policy between fork and exec as a hook, using libnuma. Only support memory tuning on domain process currently. For the nodemask out of range, will report soft warning instead of hard error in libvirt layer. (Kernel will be silent as long as one of set bit in the nodemask is valid on the host. E.g. For a host has two NUMA nodes, kernel will be silent for nodemask "01010101"). So, soft warning is the only thing libvirt can do, as one might want to specify the numa policy prior to a node that doesn't exist yet, however, it may come as hotplug soon.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
