[Qemu-devel] [PULL 04/11] qemu-iotests: test NBD over UNIX domain sockets in 083 |
Date: |
Wed, 30 Aug 2017 13:07:04 -0500 |
From: Stefan Hajnoczi <address@hidden>
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.
