Subject: [PATCH v2 6/7] libxenstat: honour XEN_RUN_DIR
Date: Mon, 11 Jul 2016 18:28:08 +0100 [thread overview]
Message-ID: <1468258089-17357-7-git-send-email-wei.liu2@citrix.com> (raw)
In-Reply-To: <1468258089-17357-1-git-send-email-wei.liu2@citrix.com>
This is because libxl uses XEN_RUN_DIR to generate the socket path for
libxenstat while libxenstat itself uses hard-coded path, which is not
necessarily the same path as XEN_RUN_DIR. The default configuration
happened to work because XEN_RUN_DIR defaulted to /var/run/xen, which
matched the hard-coded path.
We should make libxenstat use XEN_RUN_DIR so that it works with
non-default configuration.
Generate a _paths.h because it is required to make this change work.
