Trend Micro has identified the root cause of this issue and it was related to a new feature change that affected all existing Guest VM's local database and Certificate files. The correct filename for the Guest VMs should be ds_guest_agent.xxx but the file name was changed to ds_agent.xxx
Workaround
You will need to rollback the DSVA version by following the steps below:
- Remove DSVA from NSX-T Service deployment.
- (optional) Manually download previous RHEL7 DSA build from Download Center (e.g. DS 20.0.0.7719)
- (optional) Import the RHEL7 DSA package (e.g. DS 20.0.0.7719) to DSM > Administration > Updates > Software > Local.
- Configure the DSVA appliance upgrade to specific build (e.g. DS 20.0.0.7719). From DSM > Administration > System Settings > Updates tab > Virtual Appliance Deployment from default "Latest Available (Recommended)" to specific build.
- Deploy DSVA appliance from NSX-T manager console.
- Check the DSVA appliance build info. Upon deploys successfully the appliance will upgrade to the specific build automatically.
Long-term Solution
The developer team is working on the solution and the ETA will be DS 20 LTS Release in November 2023.
