From 2d9ca5a37b12902f461d901e783cc2ffa4842b93 Mon Sep 17 00:00:00 2001 From: Cornelia Huck Date: Thu, 26 Nov 2020 14:01:58 +0100 Subject: tests/acceptance: add a test for devices on s390x This adds a very basic test for checking that we present devices in a way that Linux can consume: boot with both virtio-net-ccw and virtio-net-pci attached and then verify that Linux is able to see and detect these devices.
