From a0d15c46d153d5574f68e18ea2f027cdb98e9390 Mon Sep 17 00:00:00 2001 From: Cole Robinson Date: Wed, 31 Jul 2013 09:00:26 -0400 Subject: [PATCH] domain_conf: Add disk bus=sd, wire it up for qemu This corresponds to '-sd' and '-drive if=sd' on the qemu command line. Needed for many ARM boards which don't provide any other way to pass in storage. --- docs/formatdomain.html.in | 3 ++- docs/schemas/domaincommon.rng | 1 + src/conf/domain_conf.c | 4 +++- src/conf/domain_conf.h | 1 + src/qemu/qemu_command.c | 20 +++++++++++++++----- 5 files changed, 22 insertions(+), 7 deletions(-) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index 78e132e..1314806 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -1660,7 +1660,8 @@ as a device ordering hint.
