Subject: [PATCH RFC 3/5] libxl/FreeBSD: write blkback "path" node
Date: Fri, 22 May 2015 11:18:56 +0200 [thread overview]
Message-ID: <1432286338-56077-4-git-send-email-roger.pau@citrix.com> (raw)
In-Reply-To: <1432286338-56077-1-git-send-email-roger.pau@citrix.com>
FreeBSD blkback doesn't use the physical-device xenstore node because it
can handle both block devices and raw files directly. Instead introduce a
new xenstore blkback node that is used by hotplug scripts to write the path
to the block device or raw image.
