If a VM is a virtual machine, then a shielded VM must be a virtual machine that is shielded or protected in some way, right?

It sounds simple, but there are some decent requirements for making this happen. For the BitLocker encryption to work properly, the VM is injected with a virtual Trusted Platform Module (TPM) chip. TPMs are quickly becoming commonplace at a hardware level, but actually using them is still a mysterious black box to most administrators. Shielded VMs can also be locked down so that they can only run on healthy and approved host servers, which is an amazing advantage to the security-conscious among us. This capability is provided...
