Abstract:
Systems and methods for key management for encrypted virtual machines are disclosed. An example method may include receiving, by a source hypervisor running on a source host machine, a notification that a guest initialization is complete for migration of a virtual machine from the source hypervisor to a destination hypervisor, wherein the guest initialization comprises storing secret data associated with the virtual machine in an encrypted memory; initiating the migration of the virtual machine from the source host machine to the destination host machine in view of the notification; and transmitting, by the source hypervisor, an execution state of the virtual machine to the destination hypervisor, the execution state comprising at least a portion of the encrypted memory that stores the secret data. In some embodiments, the secret data comprises a cryptographic key.

Claim (Index 20):
A non-transitory machine-readable storage medium including instructions that, when accessed by a processing device, cause the processing device to:\n receive, using a source hypervisor running on a source host machine, a notification that a guest initialization is complete for migration of a virtual machine from the source hypervisor to a destination hypervisor running on a destination host machine, wherein the guest initialization comprises storing secret data associated with the virtual machine in an encrypted memory; initiate, using the source hypervisor, the migration of the virtual machine from the source host machine to the destination hypervisor in view of the notification; and transmit, using the source hypervisor, an execution state of the virtual machine to the destination hypervisor, the execution state comprising at least a portion of the encrypted memory that stores the secret data.
