[PATCH v5 02/20] qemu-interop: ignore non-readable directories

[marcandre.lureau@xxxxxxxxxx]

From: Marc-André Lureau <marcandre.lureau@xxxxxxxxxx>

Whether a directory is missing or is not readable doesn't make much
difference when populating the available configs.

This removes errors when firmare or vhost-user config is looked up
from a user session libvirt if /etc/libvirt is not readable for ex.
