manually umount all vboxsf fs before shutdown fixes the issue.
may I fill a bug report ?

steps to reproduce on windows or linux host :
1. Create a VM : type Linux, Version ArchLinux
2. install the OS :
https://wiki.archlinux.org/index.php/Installation_Guide
3. Configure a virtualbox shared folder with Auto-mount and permanent box checked
4. startup the VM and check that shared folder is mounted
5. poweroff the VM
6. VM crashes while umounting the fs type vboxsf in the vobxsf module at sf_remount_fs() in systemd-shutdown process.

I would suggest not using the auto-mount and instead create a manual mount. You can place this in the /etc/rc.local, or equivalent if you want it mounted at boot.

Yes, it is a possible workaround, but it's a bug. I'm going to fill a public bug report.
