When an error occurs sending keys from the key server to an ESXi host, vCenter Server generates a message in the event log for the following events: Depending on if the key is for a virtual machine or a host, it might have x-Component, x-Identifier, and x-Name attributes appended. These attributes are set when the key is generated. x-Vendor, x-Product, and x-Product_Version might be the same for both keys. Check with your key server vendor.īoth the host key and virtual machine key have the six custom attributes. You might be able to view these custom attributes in your key server user interface. When the key is used to encrypt a virtual machine or host, vCenter Server sets the x-Component, x-Identifier, and x-Name attributes. VCenter Server adds the x-Vendor, x-Product, and x-Product_Version attributes when the key server creates a key. Host Encryption Custom Attributes Custom Attribute Virtual machine's instanceUuid (gathered from ConfigInfo or ConfigSpec) Virtual machine name (gathered from ConfigInfo or ConfigSpec) Virtual Machine Encryption Custom Attributes Custom Attribute vCenter Server adds the following custom attributes for virtual machine keys and host keys. Custom attributes enable you to more specifically identify keys stored in your key server. The Key Management Interoperability Protocol (KMIP) supports adding custom attributes intended for vendor-specific purposes. The difference is that vSphere Native Key Provider generates the keys and wraps them with the primary key, then hands them back to perform encryption. The encryption process flow is similar to how a trusted key provider works.

Likewise, if you update or delete a vSphere Native Key Provider, the change is pushed to the hosts in the cluster. When you configure a vSphere Native Key Provider, vCenter Server pushes a primary key to all ESXi hosts in the cluster. VSphere Native Key Provider is included in vSphere starting with the 7.0 Update 2 release. VSphere Native Key Provider Encryption Process Flow Only Trusted Hosts can request encryption operations from Trust Authority Hosts.vCenter Server no longer pushes keys to ESXi hosts and instead it can treat each trusted key provider as a single top-level key.Instead, vSphere Trust Authority publishes trusted key providers that the Trusted Hosts can use. Trust Authority administrators do not specify information directly when setting up a key server for a vCenter Server instance, and they do not establish the key server trust. The encryption process for the trusted key provider has some important differences from the standard key provider: The existing Cryptographic privileges added for vSphere 6.5 are still relevant in vSphere 7.0 for vSphere Trust Authority. And, you can still use the APIs in a similar way to specify the key provider manually. You still use a default configured key provider (called a KMS cluster in vSphere 6.5 and 6.7) when encrypting a virtual machine from the vSphere Client. Virtual machine encryption under vSphere Trust Authority continues to rely on either virtual machine encryption storage policies, or the presence of a vTPM device, to decide when to encrypt a virtual machine. The vSphere Trust Authority encryption process flow includes the vSphere Trust Authority services, the trusted key providers, the vCenter Server, and the ESXi hosts.Įncrypting a virtual machine with a trusted key provider looks the same as the virtual machine encryption user experience when using a standard key provider. Trusted Key Provider Encryption Process Flow The ESXi host encrypts the virtual machine with the encrypted internal key.Īny hosts that have the KEK and that can access the encrypted key file can perform operations on the encrypted virtual machine or disk.Because the KEKs come from the key server, the host continues to use the same KEKs. Unencrypted internal keys are never stored on disk. It keeps the internal keys in memory only, and uses the KEKs to encrypt internal keys. The ESXi host generates internal keys (DEKs) for the virtual machine and its disks.
The key itself is not stored on the vCenter Server system. If the ESXi host is part of a cluster, vCenter Server sends the KEK to each host in the cluster.
