Public Instance Methods

add(node, opts = {}) click to toggle source

Creates a new virtual NUMA node for the virtual machine.

An example of creating a NUMA node:

source

POST /ovirt-engine/api/vms/c7ecd2dc/numanodes Accept: application/xml Content-type: application/xml


The request body can contain the following:

source,xml

<vm_numa_node>

<cpu>
  <cores>
    <core>
      <index>0</index>
    </core>
  </cores>
</cpu>
<index>0</index>
<memory>1024</memory>

</vm_numa_node>


@param node [VirtualNumaNode] The `node` to add.

@param opts [Hash] Additional options.

@return [VirtualNumaNode]
