The launching of a hypervisor after there is already a running operating system. The operating system itself may launch the hypervisor. The running operating system may be used instead of the hypervisor to discover the physical resources running on the computing system. Other operating systems or operating system instances may be launched after the hypervisor is operational.

Launching hypervisor under running operating system

Communication of information via an in-band channel using a trusted configuration space is provided. The introduction of using a trusted configuration space associated with a computer bus system, such as PCI Express&#xae; (PCIe&#x2122;), for example, enables the design of trusted computing platforms capable of providing compliant devices with assurance that their trusted configuration registers can only be accessed by software running in the trusted software environment. Establishing device trust in the software that initiates trusted configuration requests makes it possible to secure and control access to certain secret, sensitive, or personally-identifiable information these devices may contain (e.g., a uniquely-identifying public key, as described above or certificate which the device provides for revocation purposes).
