However the same behavior as for Auto-mounting happens. In Settings -> Shared Folders dialog I unchecked Auto-mount checkbox and added a valid value in Mount point (eg. I left Mount point empty.Īfter the above setup I boot the Ubuntu 20 VM and I was expecting to see the mount under /media/sf_shared and I did see it however it was empty even though on the host machine there are several files. I created an entry under VirtualBox Ubuntu 20.04 VM Settings -> Shared Folders and completed the Folder Path to a valid Windows(host) location, the Folder Name (called shared) and checked Auto-mount and Make Permanent. I entered /home/jim/share and it worked fine.I followed (among other related threads) in order to mount a shared folder in my Ubuntu 20.04 VM. It complained that it was not an absolute address. Note: Running on Ubuntu 10.04 host and Mint 14 as virtual system, the system would not accept a ~/share. If the guest machine is expecting "share" (as we did in the Prepare Host section) and you wrote sharename="donotshare" Make sure you specified the right name on the bash commands. The above error could be one of the following. sbin/mount.vboxsf: mounting failed with the error: Protocol error Note: if you want to mount the directory as owned and writable only by root, omit the -o uid=1000,gid=1000 option to the mount command See Section 4.4 "Folder Sharing" in the VirtualBox documentation. Ubuntu 10.04 and later) HOWTO Use Shared Folders If you want to have it mount automatically upon each boot, put the mount command in /etc/rc.local Debian distros (e.g. Ln -s /mnt/$sharename $HOME/Desktop/$sharenameįor the above command if you get the following error: mount: unknown filesystem type 'vboxsf' Sudo mount -t vboxsf -o uid=1000,gid=1000 $sharename /mnt/$sharename This can be done more generically with the following: sharename="." Now anything placed in this folder should be visible from the host in the ~/share folder. On the Windows Guest, run net use x: \\vboxsvr\share With a shared folder named share, as above, the folder can be mounted as the directory ~/host with the command sudo mount -t vboxsf -o uid=$UID,gid=$(id -g) share ~/host Optionally select the 'Make permanent' option.For instructions on how to do this, see Guest Additions.Ĭreate a folder on the Host computer (ubuntu) that you would like to share, for example ~/shareīoot the Guest operating system in VirtualBox. But the steps you take are similar to setting up file sharing over real networks.)īefore sharing folders, you must install Guest Additions. For virtual machines, the network between host and guest is virtual since they are on the same real machine.

(Files are shared over a network, in other words, you access remote files. This explains how to share files and folders (directories) between host and guest.
