Clipboard sharing

When this option is enabled and the SPICE guest tools are installed, the clipboard will be synced between the guest and the host.

Shared directory

Two methods of directory sharing are supported by UTM.


This requires the SPICE guest tools to be installed on the guest. The shared directory is exposed as a WebDAV mount on the guest’s localhost (typically on port 9843). This option has better support for Windows but can have worse performance than VirtFS on Linux.


This requires the guest operating system to have driver support for 9pfs and VirtIO. The shared directory is exposed under the VirtFS tag share. Note that unlike WebDAV, the shared directory cannot be changed while the VM is powered on. There is currently a lack of Windows support but the performance on Linux is much better so this is the recommended option if you are running Linux. See this page for more information.
