Provision of a virtual secure cryptoprocessor (VSC) for a guest virtual machine (VM), part of a first guest, of a hypervisor of a computer system, includes (i) storing guest VM state and VSC state together in an encrypted virtual hard disk drive file, (ii) storing a decryption key in a sealed partition, of a second guest, sealed against a physical secure cryptoprocessor, (iii) based on verifying that a host computing environment of the computer system is in a trusted state and on booting the hypervisor thereon, unsealing the sealed partition of the second guest, the unsealing providing the decryption key, and decrypting the encrypted virtual hard disk drive file using the decryption key, where the decrypting decrypts the stored guest VM state for execution of the guest VM and decrypts the VSC state to provide the VSC for use by the guest VM.
