From 59589247b3892db3cf4113229dbf235bae66c2a9 Mon Sep 17 00:00:00 2001 From: Amit Shah Date: Thu, 14 Jan 2010 09:38:05 -0200 Subject: [PATCH 7/8] virtio-serial: Add a 'virtserialport' device for generic serial port support RH-Author: Amit Shah Message-id: <1263461886-32077-8-git-send-email-amit.shah@redhat.com> Patchwork-id: 6354 O-Subject: [RHEL 6 PATCH v4 7/8] virtio-serial: Add a 'virtserialport' device for generic serial port support Bugzilla: 543825 RH-Acked-by: Gerd Hoffmann RH-Acked-by: Juan Quintela RH-Acked-by: Markus Armbruster This patch adds generic serial ports over the virtio serial bus. These ports have a few more options that are not relevant for virtio console ports. Sample uses for such a device can be obtaining info from the guest like the file systems used, apps installed, etc. for offline usage and logged-in users, clipboard copy-paste, etc. for online usage.
