From 17123cdd168f84466b1ea00f1825f26814c2bd9b Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Wed, 27 Sep 2017 17:57:24 +0200 Subject: [PATCH 6/7] qemu-iotests: test NBD over UNIX domain sockets in 083 RH-Author: Eric Blake Message-id: <20170927175725.20023-7-eblake@redhat.com> Patchwork-id: 76670 O-Subject: [RHEV-7.4.z qemu-kvm-rhev PATCH 6/7] qemu-iotests: test NBD over UNIX domain sockets in 083 Bugzilla: 1495474 RH-Acked-by: Max Reitz RH-Acked-by: Jeffrey Cody RH-Acked-by: Stefan Hajnoczi From: Stefan Hajnoczi 083 only tests TCP. Some failures might be specific to UNIX domain sockets. A few adjustments are necessary: 1. Generating a port number and waiting for server startup is TCP-specific. Use the new nbd-fault-injector.py startup protocol to fetch the address. This is a little more elegant because we don't need netstat anymore. 2. The NBD filter does not work for the UNIX domain sockets URIs we generate and must be extended. 3. Run all tests twice: once for TCP and once for UNIX domain sockets.
