This test case checks if the console connection code works in a safe way that the connection don't get messed up. --- Diff to v1: -- removed semicolons at the end of statements (the C language left some habits :D) -- added call to usage function (I thought it's called automaticaly. With this this could be another good function to incorporate in the class and free the test-writer from re-implementing it again and again) -- added cleanup function (same comment as above; note: there are some tests that don't have this func.) -- refactored getting of optional parameter "device" -- added cleanup of stream objects (they'd got cleaned up automaticaly with the disconnect, but this is safer and enables testing if the stream was in a good state) repos/domain/console_mutex.py | 107 +++++++++++++++++++++++++++++++++++++++++ 1 files changed, 107 insertions(+), 0 deletions(-) create mode 100644 repos/domain/console_mutex.py diff --git a/repos/domain/console_mutex.py b/repos/domain/console_mutex.py new file mode 100644 index 0000000..50730e0 --- /dev/null +++ b/repos/domain/console_mutex.py @@ -0,0 +1,107 @@ +#!/usr/bin/env python +""" A test case to test console mutual exclusivity + mandatory arguments: guestname +""" +import libvirt +from libvirt import libvirtError +from exception import TestError + +from utils.Python import utils + +def usage(params): + """Verify parameter dictionary""" + logger = params['logger'] + keys = ['guestname'] + for key in keys: + if key not in params: + logger.error("%s is required" %key) + return 1 + +def console_mutex(params): + """Attach to console""" + usage(params); + logger = params['logger'] + guest = params['guestname'] + device = params.get('device', 'serial0') + + util = utils.Utils() + uri = params['uri'] + + try: + logger.info("Connecting to hypervisor: '%s'" % uri) + conn = libvirt.open(uri) + dom = conn.lookupByName(guest) + + if not dom.isActive(): + raise TestError("Guest '%s' is not active" % guest) + + logger.info("Creating stream object") + stream = conn.newStream(0) + + logger.info("Forcibly open console on domain") + dom.openConsole(device, stream, libvirt.VIR_DOMAIN_CONSOLE_FORCE) + + logger.info("Creating another stream object") + stream2 = conn.newStream(0) + + logger.info("Open safe console connection while an existing one is open") + try: + dom.openConsole(device, stream2, libvirt.VIR_DOMAIN_CONSOLE_SAFE) + except libvirtError, e: + if e.get_error_code() == libvirt.VIR_ERR_OPERATION_FAILED: + logger.info("Opening failed - OK") + else: + raise e + else: + raise TestError("Opening of console succeeded although shoud fail") + + logger.info("Abort the existing stream") + stream.abort() + + logger.info("Re-try connecting to the console") + dom.openConsole(device, stream2, libvirt.VIR_DOMAIN_CONSOLE_SAFE) + + logger.info("Re-try forcibly on already open console") + + logger.info("Creating stream object") + stream = conn.newStream(0) + + dom.openConsole(device, stream, libvirt.VIR_DOMAIN_CONSOLE_FORCE) + + logger.info("Clean up streams") + stream.finish() + + try: + stream2.finish() + except libvirtError, e: + if e.get_error_code() == libvirt.VIR_ERR_RPC and \ + e.get_error_domain() == libvirt.VIR_FROM_STREAMS: + logger.info("Stream was aborted successfuly") + else: + raise e + else: + raise TestError("stream2 should be aborted after forced console connection") + + except libvirtError, e: + logger.error("Libvirt call failed: " + str(e)) + ret = 1 + + except TestError, e: + logger.error("Test failed: " + str(e)) + ret = 1 + + else: + logger.info("All tests succeeded") + ret = 0 + + finally: + logger.info("Closing hypervisor connection") + conn.close() + + logger.info("Done") + + return ret + +def console_mutex_clean(params): + """clean testing environment""" + pass -- 1.7.3.4

Maybe it's copy-paste error from other tests where these were leftover even though they are not needed anymore after the cleanup of "get_uri()".
