23.11. Resource Partitioning

Hypervisors may allow for virtual machines to be placed into resource partitions, potentially with nesting of said partitions. The <resource> element groups together configurations related to resource partitioning. It currently supports a child element partition whose content defines the path of the resource partition in which to place the domain. If no partition is listed, then the domain will be placed in a default partition. The partition must be created prior to starting the guest virtual machine. Only the (hypervisor-specific) default partition can be assumed to exist by default.

<resource>
  <partition>/virtualmachines/production</partition>
</resource>

<resource>
  <partition>/virtualmachines/production</partition>
</resource>

Resource partitions are currently supported by the KVM and LXC drivers, which map partition paths to cgroups directories in all mounted controllers.
