A hypervisor boots all guest operating systems needed to setup/update server components as detected by an update utility. The update utility, after detecting server components, is booted into each guest O.S. so that the components are updated in parallel without having to sequentially boot the utility into a guest O.S., update its component, then shut down and re-boot into another guest O.S.

Multiple guest O.S. boot for server component setup

A method, computer program, and system for paging platform configuration registers in and out of a trusted platform module. In a trusted computing platform, an unlimited number of platform configuration registers can be obtained through paging. The trust platform module encrypts and decrypts platform configuration registers for storage outside the trusted platform module.

Scalable paging of platform configuration registers

A method for a plurality of key cache managers for a plurality of localities to share cryptographic key storage resources of a security chip, includes: loading an application key into the key storage; and saving a restoration data for the application key by a key cache manager, where the restoration data can be used by the key cache manager to re-load the application key into the key storage if the application key is evicted from the key storage by another key cache manager. The method allows each of a plurality of key cache managers to recognize that its key had been removed from the security chip and to restore its key. The method also allows each key cache manager to evict or destroy any key currently loaded on the security chip without affecting the functionality of other localities.
