but the problem is likely to be here:
src/drives.c:
/* Skip the mandatory leading '/' character on exportname. */
return safe_asprintf (g, "rbd:%s:mon_host=%s%s%s%s",
&src->u.exportname[1],
mon_host,
username ? username : "",
auth,
secret ? secret : "");
The problem that this code is trying (and failing) to deal with is
that when you use the URL on the guestfish command line, the URL is
something like "rbd://example.com/foo/bar" and the path part of this
has to start with a "/" character. There is simply no way to specify
a URL without this.
However this assumption should *not* have made its way into the
libguestfs library, since other paths into this code, such as from
libvirt XML, have no such restrictions.
So it's currently somewhat broken.
