Using shielded VMs for HVA. To obtain the necessary keys, the guarded host must provide the following to KPS: Release of key. Shielded VMs are virtual machines (VMs) on Google Cloud hardened by a set of security controls that help defend against rootkits and bootkits. The IP Address is 10.0.0.4. The Attestation service ensures only trusted Hyper-V hosts can run shielded VMs while the Key Protection Service provides the keys necessary to power them on and to live migrate them to other guarded hosts. This is a fundamental danger for every virtualization platform today, whether it's Hyper-V, VMware or any other. KPS examines the health certificate to determine its validity.

Shielded VMs, or Shielded Virtual Machines, are a security feature introduced in Windows Server 2016 for protecting Hyper-V Generation 2 virtual machines (VMs) from unauthorized access or tampering by using a combination of techniques like Secure boot, Bit-locker encryption, virtual Trusted Platform Module and the Host Guardian Service. Alternative debugging techniques, such as those used by LiveKd.exe, are not blocked. The following table summarizes the differences between encryption-supported and shielded VMs. The attestation mode determines which checks are needed to successfully attest the host is healthy. When a tenant creates shielded VMs that run on a guarded fabric, the Hyper-V hosts and the shielded VMs themselves are protected by the HGS. When deploying new shielded VMs, tenants are able to specify which template disks they trust.
