@danko-miladinovic is working on this.

It is important to figure out:

1. How our Agent needs to be changed to fetch the attestation from GCP and Azure
2. How our CLI needs to be changed in order to verify the attestation

@danko-miladinovic please procced with this one, add support in our Dell machine.

Please assign to @dorcaslitunya an issue to work on change for Agent or CLI code change for attestation with you.

@danko-miladinovic Any updates on this?

@dorcaslitunya is working on changing the Buildroot config based on the COCONUT-SVSM so we get an kernel image with vTPM support. I am working on verifying the vTPM PCR values based on the event log of the vTPM on DELL because on DELL we have all the components needed to calculate the PCRs values. For now there are some mismatches and I am looking into the problem.
