Public bug reported:

systemd-analyze reports a slow boot in a virtual machine. Steps to
reproduce:

1. Install ubuntu-23.04-desktop-amd64.iso in a VM (8 cores, 4 GB memory). Select all default but unselect requiring to enter the password to login
2. Reboot and install all updates
3. Reboot the virtual machine. The machine will take several seconds to boot and login
4. Open a terminal and enter systemd-analyze

Expected total reported boot time on my hardware: around 3.5 seconds

But I got:

$ systemd-analyze
Bootup is not yet finished (org.freedesktop.systemd1.Manager.FinishTimestampMonotonic=0).
Please try again later.
Hint: Use 'systemctl list-jobs' to see active jobs
$ systemctl list-jobs
