I have a PC with Windows 7x64. I installed Oracle VM (v. 5.2.20). In the VM I installed Ubuntu 18.04 and created a shared folder in the VM. The shared folder has name vp and refers to d:\vp folder on Windows.

In Ubuntu, I set up auto-mounting and now this folder is displayed in Ubuntu as sf_vp.

Next, I want to mount this shared folder to my folder on Ubuntu /home/roman/vp.

I can do it on working Ubuntu via the command:

sudo mount -t vboxsf -o uid=1000,gid=1000 vp ~/vp

It works successfully, but when I add this line:

vp /home/roman/vp vboxsf uid=1000,gid=1000

into /etc/fstab file and reboot Ubuntu, it somehow doesn't mount upon loading Ubuntu, if writes "FAILED mounting ...".

And if I add this string into /etc/fstab and execute a command

sudo mount -a

without a reboot, it also works and the folder /home/roman/vp is mounted successfully.

Could you clarify me, what doesn't mounting work upon loading Ubuntu?

I want to repeat, Ubuntu is installed in Oracle VM and vp is a shared folder, it set up in Oracle VM too.

  • By default the VBox shared folders are mounted to /media without any entries in /etc/fstab Have you checked there? I recommend removing entries from /etc/fstab and allowing vbox to do its thing. – Stephen Boston Nov 6 '18 at 15:23
  • The matter is that I'm going to use Docker for web-development and keep my project sources in shared folders. I want to work on Windows and use VM with Ubuntu and docker as a web-server. Unfortunately, some docker-containers aren't created without mounting a shared folder to a folder in /home/roman/ (that's my user folder). Folders can be mount successfully via mount command if Ubuntu already works. But they can't be mounted upon starting of Ubuntu. – Yakimkin Roman Nov 6 '18 at 17:41
  • Hmm... now that's a wrinkle. Does a symlink work? ln -s /media/sf_vp /home/roman/vp It might. Docker is a bit of an anomaly but symlinks are usually transparent on unix. – Stephen Boston Nov 6 '18 at 20:09
  • Unfortunately, docker doesn't work correctly with symlinks. – Yakimkin Roman Nov 7 '18 at 13:06
