Abstract: A method of creating a new page table structure after first stage boot operations has completed but before handoff to a hypervisor occurs. Firmware page tables are reused and copied to a region of memory by a first-stage bootloader while the firmware is running, processed to have an expected multi-stage page table structure and desired access rights, and copied again to another region of memory by the first-stage bootloader after the first-stage bootloader has completed its booting operations and after the firmware has been quiesced.

Abstract: A method of reducing power consumption of a server cluster of host systems with virtual machines executing on the host systems is provided. The method includes recommending host system power-on when there is a host system whose utilization is above a target utilization, and recommending host system power-off when there is a host system whose utilization is below the target utilization. Recommending host system power-on includes calculating impact of powering on a standby host system with respect to reducing the number of highly-utilized host systems in the server cluster. Recommending host system power-off includes calculating impact of powering off a host system with respect to decreasing the number of less-utilized host systems in the server cluster.

Abstract: A method of re-mapping memory regions for firmware run-time services to a virtual address space of a kernel executed on a processor, includes the steps of selecting a re-mapping policy for re-mapping the memory regions for the firmware run-time services, creating a new mapping according to the selected re-mapping policy, and making a call to an application programming interface exposed by the firmware to apply the new map and re-map the memory regions for the firmware to the virtual address space of the kernel.

Abstract: A computer system is securely booted by executing a boot firmware to locate a boot loader and verify the boot loader using a first key that is associated with the boot firmware. Upon verifying the boot loader, computer system executes the boot loader to verify a system software kernel and a secure boot verifier using a second key that is associated with the boot loader. The secure boot verifier is then executed to verify the remaining executable software modules to be loaded during boot using a third key that is associated with the secure boot verifier and a fourth key that is associated with a user of the computer system.

The secure boot verifier is then executed to verify the remaining executable software modules to be loaded during boot using a third key that is associated with the secure boot verifier. During boot, state data files of the computer system are mounted in a namespace that is isolated from the namespaces in which the executable software modules are mounted.
