摘要： 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.

摘要： 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.

摘要： Systems and techniques are described for power-aware scheduling. One of the techniques includes monitoring execution of a plurality of groups of software threads executing on a physical machine, wherein the physical machine comprises a physical hardware platform that includes a plurality of processor packages having a plurality of package power states, wherein the plurality of package power states includes an independent package power state; obtaining a respective independent power state measure for each of the processor packages, wherein the independent power state measure provides a measure of a percentage of time the processor package spends in the independent package power state; and adjusting an allocation of the plurality of groups of software threads across the plurality of processor packages based in part on the independent power state measures for the packages.

摘要： Techniques for migrating virtual machines (VMs) in the presence of uncorrectable memory errors are provided. According to one set of embodiments, a source host hypervisor of a source host system can determine, for each guest memory page of a VM to be migrated from the source host system to a destination host system, whether the guest memory page is impacted by an uncorrectable memory error in a byte-addressable memory of the source host system. If the source host hypervisor determines that the guest memory page is impacted, the source host hypervisor can transmit a data packet to a destination host hypervisor of the destination host system that includes error metadata identifying the guest memory page as being corrupted. Alternatively, if the source host hypervisor determines that the guest memory page is not impacted, the source host hypervisor can attempt to read the guest memory page from the byte-addressable memory in a memory exception-safe manner.

摘要： 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.

摘要： 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.
