From e6a74868d92f858ac33915b6772999d7de2fd288 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marc-Andr=C3=A9=20Lureau?= Date: Thu, 3 Aug 2017 11:07:46 +0200 Subject: [PATCH] build-sys: add --disable-vhost-user MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Learn to compile out vhost-user (net, scsi & upcoming users). Keep it enabled by default on non-win32, that is assumed to be POSIX. Fail if trying to enable it on win32. When trying to make a vhost-user netdev, it gives the following error: -netdev vhost-user,id=foo,chardev=chr-test: Parameter 'type' expects a netdev backend type And similar error with the HMP/QMP monitors. While at it, rename CONFIG_VHOST_NET_TEST CONFIG_VHOST_USER_NET_TEST since it's a vhost-user specific variable. Signed-off-by: Marc-André Lureau Reviewed-by: Cornelia Huck Reviewed-by: Michael S.
