This addition means it should be faster opening new files within VBOXSF-backed mounts. This atomic_open functionality is based on the implementations found within Linux's 9p and FUSE code. Red Hat's Hans de Goede saw his VBOXSF fixes merged today that most notably adds support for atomic_open directory-inode operation. Does anyone has any idea of what's going on here?Īlso must mention that on the same VirtualBox I have another VM installed (Ubuntu 18.04) on which the auto-mounting is working as a charm.For those making use of VirtualBox virtualization and rely on the shared folder functionality via the mainline "VBOXSF" driver for exchanging files between VMs and the host, the in-development Linux 5.14 kernel has an important fix/improvement. However I couldn't find any relevant information of how to solve it.

Maybe the last error that I got in terminal is a hint for the root of the problem. sbin/mount.vboxsf: mounting failed with the error: Invalid argument

Sudo mount -t vboxsf -o uid=$USER,gid=vboxsf shared /home/myuser/shared The share does not work, cannot see the files under the shared folder from the host machine. 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 followed (among other related threads) in order to mount a shared folder in my Ubuntu 20.04 VM.
