This command uses a kernel filesystem driver. I'm not sure how that
works, as SPICE webdav doesn't generally use that. When you're
mounting in a GNOME desktop UI, it uses 'GIO' to mount it.

If you're logged into your sesssion, you can do that using

  gio mount dav+sd://Spice%2520folder._webdav._tcp.local/


You can use 'gio mount --list' to confirm that URL, after mounting
it from the UI.

The actual mount appears in /run/user/$UID/gvfs/$URL where $URL
is the same as the URL given to 'gio mount'
