Abstract
A computer including a processor and a verification device. The processor in the computer performs the steps of authenticating a secure connection between a hypervisor and the verification device, measuring the identity of at least a portion of a select guest before the select guest executes any instruction, and sending a measurement of the identity of the select guest to the verification device. The verification device compares the policy stored in the verification device with the measurement of the select guest received by the verification device. The steps of authenticating, measuring, sending, and comparing are performed after receiving a signal indicative of a request to execute the select guest and without rebooting the computer.
