Abstract
Briefly, aspects of the subject matter described herein relate to virtual machines. In aspects, when a host is reset or powered on, a measured boot is performed. If the measured boot indicates that the host is in a state that satisfies a policy for gaining access to a cryptographic key, the cryptographic key may be obtained. The cryptographic key may be used, directly or indirectly, to decrypt data of a virtual storage device. This decrypted data may then be used to instantiate a virtual machine.
