Welcome to the Google Cloud Community. Did you’ve tried to enable service by enabling API? Go to API & Services → Enable APIs → Type VM Manager → Choose VM Manager (OS Config API)> → Enable
I’m facing the same issue, “enable full vm manager functionality” feature is not working,
I have tried all the above steps listed by slamjammington, my confirguration is ok:
API’s enabled
Account service correctly setup
System up to date (latest image from bitnami WP/Nginx/debian 11)
os-config agent latest version
GCLOUD/CLI up to date
When I try to enable full vm manager functionality, nothing happens, just and endless timer loop.
