Describe the issue
I have recently upgraded my installation of UTM on MacOS 14.1 to the most recent version. Since then, I am unable to mount shared disks in my MacOS VM using the instructions shown at https://docs.getutm.app/guest-support/macos. Here is an excerpt from my terminal session:

Last login: Tue Nov 7 18:19:09 on console ventura@venturas-Virtual-Machine ~ % sudo mount_virtiofs share /Users/ventura/host_shared Password: mount_virtiofs: fs_tag share not found ventura@venturas-Virtual-Machine ~ %

Configuration

• UTM Version: 4.4.4
• macOS Version: 14.1 (both host and guest)
• Mac Chip (Intel, M1, ...): M2

I will attach my configuration.

@opabecker the new update auto mounts your shared directories in a volume called "My Shared Files".

On your guest macOS, go to Finder -> Computer -> My Shared Files -> all your shared directories

@cazendium Thanks!

I'm in Finder -> Computer; all I see are Macintosh HD and Network. Any advice?

UTM 4.4.5, macOS 13.6.3 guest and host also has no /Volumes/My Shared Files

You can manually mount the shared folders with:

mkdir -m 777 -p <PATH>
mount_virtiofs com.apple.virtio-fs.automount <PATH>

Confirmed MacOS 14.2. Appreciate you bringing it over from the other repository.

I tried:

mkdir -m 777 -p [path to desired location in home folder] mount_virtiofs com.apple.virtio-fs.automount [path used above]

But got this:

mount_virtiofs: fs_tag com.apple.virtio-fs.automount not found

What else is needed to get shared folders working in UTM ?

EDIT: Also, the guest VM can't see shared folders on the host. EDIT 2: Found this in UTM docs:

VirtioFS Requires virtiofs drivers and is currently only supported by the Apple backend running Linux.

So, I'm stumped as I can't get SPICE WebDAV working either.

mkdir -m 777 -p mount_virtiofs com.apple.virtio-fs.automount

i am receiving mount_virtiofs: fs_tag com.apple.virtio-fs.automount not found

any idea @simbados @section83

[simbados]

@kokoskiwi did you set up directory sharing in the config of your vm?

Also the newest Version of MacOS fixed the bug concerning the manual mount. So setting up the shared directory in your vm settings should be enough and you should be able to access the mounted files under /Volumes/My Shared Files

@dineshravichandiran were you able to solve it? I am also facing same error on M2 14.6.1 and VM with Alma 9.4.

For me the button for sharing directories is completely disabled when booting a MacOS VM
