Abstract: In one example, a system for a system management mode (SMM) privilege architecture includes a computing device comprising: a first portion of SMM instructions to set up a number of resources and implement a privilege architecture for the SMM of a computing device and a second portion of SMM instructions to execute a number of functions during the SMM of the computing device, wherein the privilege architecture assigns the first portion of SMM instructions to a first privilege level and assigns the second portion of SMM instructions to a second privilege level.

Abstract: Securely sending a complete initialization package in one example implementation can include adding a resource identifier that includes a mapping of a driver to a hardware component included in a physical machine hosting VMs to an initial random-access memory (RAM) file system (INITRAMFS) stored in memory of the physical machine to form a complete initialization package, sending the complete initialization package from read-only memory (ROM) of the physical machine to a location in RAM of the physical machine accessible by a hypervisor, and authenticating that the complete initialization package is secure.

Abstract: Example implementations relate to command source verification. An example device can include instructions executable to send a command via a predefined path to a predefined location within a memory resource storing instructions executable to verify a source of the command using a predefined protocol and execute the command in response to the source verification.

Abstract: According to one example, to access at least one computer device from a virtual machine, a control domain accesses a list of at least one device. For each device in the list of devices, a determination is made as to whether the device is to be exposed to a virtual machine, and a table of devices determined to be exposed to the virtual machine is created and provided to the virtual machine. Determining whether a device is to be exposed to a virtual machine is based on at least one device attribute.

Abstract: Full virtual machine (VM) functionality in one example implementation can include sending a complete initialization package to a location in memory of a machine accessible by a hypervisor and generating a VM capable of providing a respective full functionality of a hardware component in the machine.
