Looks like this has something to do with systemd, with zVM boot with 5.4.0-33, I can still reproduce this issue:
ubuntu@kernel04:~$ sudo systemctl stop systemd-timesyncd ubuntu@kernel04:~$ sudo systemctl start systemd-timesyncd Failed to start systemd-timesyncd.service: Unit systemd-timesyncd.service is masked. ubuntu@kernel04:~$
