Secured and reliable VM migration in personal cloud

The security and reliability issues that reside in VM live migration is a critical factor for its acceptance by IT industry. We propose to leverage Intel vPro and TPM to improve security in virtual machine live migration. A role-based mechanism with remote attestation is introduced, under which the VM migration is controlled by specific policies that are protected in seal storage. To provide high reliability in client virtualization, we also implement a checkpoint based method that only consumes 5% overall system resource according to the experimental result.
