Boot-Time Hardware Properties

When the hypervisor is booted, input parameters provide information about some aspects of the physical hardware. Aspects of the hardware that are described to the hypervisor at boot time include:

  • Present and potential logical processors, including those that can be hot-plugged at run time

  • Whether symmetric multi-threading (SMT) is enabled or disabled in the BIOS

  • Present RAM SPA ranges--system physical address ranges that are populated with RAM when the hypervisor is booted

  • Physical nodes (including those that have no associated resources at boot time but can be populated at run time)

  • Memory access ratios between physical nodes

  • Addresses of certain hardware features that the hypervisor must access (for example, the power management timer)

For more information about the hypervisor's booting procedure, see Hypervisor Booting.
