OK, good. If you're willing to invest some more work nonetheless:

As you're seeing it on a VM, maybe you could provide a serial console log taken
with "systemd.log_target=console systemd.journald.forward_to_console=1
console=ttyS0,57600n8"? In libvirt, you can connect e.g. "screen" to the serial
port of the VM (which appears as /dev/pts/$X device on the host, you can see it
e.g. with "virsh dumpxml"), and log the screen session. qemu has various 
methods to redirect a virtual serial console to a file.

The reason I'm asking is to identify at which point exactly in the shutdown
sequence the messages occur.
