numa

The numa hook adds numa support to a VM’s XML definitions. This can help improve a VM placement on the NUMA nodes of a NUMA-enabled host

The libvirt XML will have the following entry added:

`    `

Syntax:

numa=`:`

Where memory policy can be

  • interleave
  • strict
  • preferred

And the numa set will look like this:

  • numaset=”1” (use one NUMA node)
  • numaset=”1-4” (use 1-4 NUMA nodes)
  • numaset=”^3” (don’t use NUMA node 3)
  • numaset=”1-4,^3,6” (or combinations)

Examples:

  numa=strict:1-4
  numa=strict:5
  numa=interleave:1-4,^3,6
