Add shared folder in VirtualBox

Here are the steps:

1. Add the Shared Folder in VirtualBox:
   • Go to the VirtualBox Manager.
   • Select your running VM and go to Devices > Shared Folders > Shared Folders Settings.
   • Click on the + icon to add a new shared folder.
   • Choose the folder path on your host machine and give it a name (e.g., shared_folder).
   • Check the Auto-mount option.
   • Optionally, specify a mount point (e.g., /mnt/shared_folder).
2. Install Guest Additions (if not already installed):
   • In the VM, open a terminal and run:

     su -c 'apt-get update'
     su -c 'apt-get install build-essential dkms linux-headers-$(uname -r)'
     

   • In the VirtualBox menu, go to Devices > Insert Guest Additions CD image.
   • Mount the CD image and run the installer:

     su -c 'mount /dev/cdrom /mnt'
     su -c '/mnt/VBoxLinuxAdditions.run'
     su -c 'reboot'
     

3. Verify the Shared Folder:
   • After rebooting, check if the shared folder is automatically mounted:

     ls /mnt/shared_folder
     

   • If it is not automatically mounted, you can manually mount it:

     su -c 'mkdir -p /mnt/shared_folder'
     su -c 'mount -t vboxsf shared_folder /mnt/shared_folder'
     

Make sure that shared_folder in the mount command matches the name you specified in the VirtualBox shared folder settings. If you named it something else, use that name instead.

permission denied?

To resolve the “permission denied” issue for your shared folder in VirtualBox, follow these steps:

1. Add User to vboxsf Group: Ensure your user is part of the vboxsf group.

   sudo usermod -aG vboxsf your_username
   

   Replace your_username with your actual username.

2. Reboot the VM: Reboot your virtual machine to apply the group changes.

   sudo reboot
   

3. Verify Access: After rebooting, check if you can access the shared folder.

   ls /mnt/shared_folder
   

This should resolve the permission issue and allow you to access the shared folder.
