Abstract
A system includes at least a secure-boot file, a hypervisor, and a host. The secure-boot file is configured to securely boot a VM, where the secure-boot file is signed with a boot private key. The hypervisor is configured to run the VM. The hypervisor includes a boot public key corresponding to the boot private key, such that the hypervisor is configured to validate the secure-boot file, and the hypervisor is signed with a hypervisor private key. A kernel of the host is configured to run the VM, where the kernel includes a hypervisor public key corresponding to the hypervisor private key, such that the host is configured to validate the hypervisor.
