[Xen-devel] [PATCH 5/6] libxl: vncviewer: unconditionally read listen port address and password

[Ian Jackson <ian.jackson@xxxxxxxxxxxxx>]

The /local/domain/DOMID/device/vfb/0/backend path is irrelevant.
libxl does not create it, so the branch would never be taken.

Instead, simply read the target paths of interest.
