How can I manually pin a virtual guest to a specific NUMA node?

Issue

  • How can I manually pin a virtual guest to a specific NUMA node?
  • In virt-install, there's an existing option to specify a cpuset, and it takes a parameter called "auto" as the cpuset. This finds a NUMA configuration that fits. Is it possible to manually specify a NUMA node for the guest to go on?
