For the truly lazy  no typing  only totally easy copy and paste    sudo usermod -aG vboxsf  USER   Log out and back in to make the change active   I know it s a  me too  solution  but I am truly lazy and didn t find any other solution to appeal my innate apathy

For VirtualBox 5 0 24  Host Mac El Capitan  and Guest RHEL 7 2   Start up your RHEL Guest VM and open up a Terminal  Make sure you have the Developer Tools installed   sudo yum groupinstall  Developer Tools    And the Kernel headers package so that the Guest Additions script can update your kernel   sudo yum install kernel-devel    Once you have the prereqs in place its time to install the Guest Additions  With your running VM selected go to the VirtualBox menu and select Devices --  Insert Guest Additions CD image       Allow a few seconds for the mount to occur and the install script to kick off  Once they have click the  Run  button in the dialog that popped up in your Guest VM   After the script finishes right click the CD Icon on the Desktop and choose Eject  Then Shutdown the Guest VM   Create the Shared folder in you Host system using Terminal  I usually put it in my Documents folder  and make sure that your user can access it   sudo mkdir   Documents RhelShared sudo chmod 755  lt user gt    Documents RhelShared   In the Oracle VM Virtual Box Manager select your VM and then click on the  Shared folders  configuration element  In the next dialog click on the Add Folder icon to the right of the Folders List    Then in the popup window select the Host Folder you just created as the Folder Path and give it a Folder Name that will be used by the Guest VM  also tick the  Auto Mount  check-box     After rebooting the Guest VM launch a terminal on the Host and check the user that is associated with the running VirtualBox Guest process is either your user  very likely  or in a group with access to the Shared folder   ps aux   grep VirtualBoxVM   Then as per several of the previous answers in a Terminal on the Guest VM add your user to the vboxsf group   sudo usermod -a -G vboxsf  lt user gt    Log out and in again to pickup the change   The shared folder should now be available and accessible as sf rhelshared assuming you used the same names as I did in the popup window above

The issue is that the shared folder s permissions are set to not allow symbolic links by default  You can enable them in a few easy steps     Shut down the virtual machine  Note your machine name at Machine  gt  Settings  gt  General  gt  Name Note your shared folder name at  Machine   Settings   Shared Folders  Find your VirtualBox root directory and execute the following command  VBoxManage setextradata    VBoxInternal2 SharedFoldersEnableSymlinksCreate  1 Start up the virtual machine and the shared folder will now allow symbolic links

Add yourself to the vboxsf group within the guest VM   Solution 1  Run sudo adduser  USER vboxsf from terminal   On Suse it s sudo usermod --append --groups vboxsf  USER   To take effect you should log out and then log in  or you may need to reboot   Solution 2  Edit the file  etc group  you will need root privileges   Look for the line vboxsf x 999 and add at the end  yourusername -- use this solution if you don t have sudo   To take effect you should log out and then log in  or you may need to reboot

In my personal experience  it s difficult to enable shared folders in VirtualBox but it Is posible  I have a debian Buster guest virtual machine installed in my Windows 10 host    I don t recognize exactly what did it  but I remember I went to Windows defender  my antivirus to see if they recognize VirtualBox as a program and not as a virus  After that  I press right click on the document file and allowed to share the folder and I gave click to some buttons there and accepted to share with groups and with muy user in Windows 10    Also  I found a webpage of Windows about something like virtual machines that I don t remember well  but it took me to a panel and I had to change three things double clicking so when I update Windows  it recognizes my virtual machine  Also  in muy debian  in the terminal  using some command lines  muy VirtualBox recognized my user giving permissions  I based on some info in the Ubuntu forums  I put all what I remember

After adding the user to the vboxsf group  you might need to completely log out of the gnome xfce     session  because someone long ago decided that group affiliation should be cached at first login to the window system   Or go old school     newgrp vboxsf   in any shell you want to use to access the folder   Luckily  newgrp looks up the group list for itself and doesn t used the cached values   You ll still need to log out and back in to access the folder from something other than a shell
