Symptoms

When an ESXi host does not pass attestation, the kmxa.log on the host reports the following:

error kmxa[66720] [Originator@6876 sub=Libs] Attestation handshake with sb-esxi-02.domain.local:443 failed to yield a token

Cause

If you replace a TPM device on an ESXi host in a Trusted Cluster, or replace the certificate of the TPM device, the attestation might fail for that ESXi host. You must obtain the certificate of the replaced TPM and update the vSphere Trust Authority configuration.

Resolution

Prerequisites:

You must be at least a Trust Authority administrator.

Procedure:

Perform the following steps on the Trusted Host that is currently failing to attest.

In a PowerCLI session, connect to the ESXi host that is failing to attest using the root user.

Connect - VIServer -server esxi_host -User root -Password ‘password'

Assign the ESXi host to a variable.

$vmhost = Get-VMHost

Assign the TPM Endorsement Key to a variable.

$tmp2 = Get-Tpm2EndorsementKey -VMHost $vmhost

Export the TPM CA Certificate from the ESXi host. Ensure that the destination directory exists before running this command.

Export - Tpm2CACertificate -Tpm2EndorsementKey $tmp2 -FilePath C:\vta\cacert.zip

Perform the following steps on the vSphere Trust Authority Cluster.

Run the following commands to disconnect any current connection and connect to the vCenter Server of the Trust Authority Cluster using the Trust Authority administrator user.

Disconnect - VIServer -server * -Confirm:$false
Connect - VIServer -server TrustAuthorityCluster_VC_ip_address -User trust_admin_user -Password 'password'

Assign the Trust Authority Cluster to a variable.

$TAcluster = Get-TrustAuthorityCluster "SB-Cluster"

Import the TPM CA certificate previously exported from the ESXi host in step 1d.

New - TrustAuthorityTpm2CACertificate -Name tpmca -TrustAuthorityCluster $TAcluster -FilePath C:\vta\cacert.zip

On the Trusted Host that is failing to attest, restart services or reboot the host.
