We can split the change to 2 PRs, we first merge the eventlog parsing logic, and wait for it to deploy to the service. And then merge the measuring logic PR, so the image test can pass here.

Looks like confidential space VMs failed to start due to unknown COS event type errors returned by VerifyAttestation if we add measuring logics to this PR.
Done.

Can be more definitive here, by making sure the len(cosTlv.EventContent) == 1

And for failsafe, I think the default value for cosState.HealthMonitoring.MemoryEnabled should be true, and when we see the eventContent == 0 here, we can turn it to false

Discussed offline, we agree to keep the default value as false.
