Hum, strange, that's still a valid absolute URI except with an empty
path I find strange we have a problem with this, as we don't use the
path for the access in practice ...
It is a bug in xend_internal.c
if (strcasecmp (name, "xen") == 0 ||
strncasecmp (name, "xen:///", 7) == 0) {
This needs to die & be replaced with code calling the libxml URI parsing.
I fixed a similar bug in the QEMU driver a few weeks back.
The check for a plain 'xen' is also now redundant, since src/libvirt.c
turns that into a well-formed URI before it gets passed into the Xen
driver:
/* Convert NULL or "" to xen:/// for back compat */
if (!name || name[0] == '\0')
name = "xen:///";
/* Convert xen -> xen:/// for back compat */
if (!strcasecmp(name, "xen"))
name = "xen:///";
