This avoids each test needing to add it to suppress windows popping up. [Commit 7ceeedd016facf8d58e14a0d1417fa7225d71072 ("blockdev-test: add test case for drive_add duplicate IDs") and commit 43cd209803d6cffb1e1a028c9ff2fd0ff4fce954 ("qdev-monitor-test: add device_add leak test cases") added qtest tests without specifying -display none. As a result, "make check" now tries to use graphics (GTK or SDL). Since graphics are not used by the test and inappropriate for headless "make check" runs, add the missing -display none. This fixes "make check" in the QEMU buildbot. -- Stefan] Signed-off-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
