23.14. Power Management

It is possible to forcibly enable or disable BIOS advertisements to the guest virtual machine operating system using conventional management tools which affects the following section of the domain XML:

  ...
  <pm>
    <suspend-to-disk enabled='no'/>
    <suspend-to-mem enabled='yes'/>
  </pm>
  ...


Figure 23.24. Power Management

The <pm> element can be enabled using the argument yes or disabled using the argument no. BIOS support can be implemented for S3 using the suspend-to-disk argument and S4 using the suspend-to-mem argument for ACPI sleep states. If nothing is specified, the hypervisor will be left with its default value.
