Hi All, Several people have reported on IRC that they can't get openstack working on RHEL 6.1. Starting the openstack-nova-network service (and various others) causes this traceback:
(nova): TRACE: File "/usr/lib64/python2.6/subprocess.py", line 725, in communicate (nova): TRACE: stdout, stderr = self._communicate(input, endtime) (nova): TRACE: File "/usr/lib64/python2.6/subprocess.py", line 1322, in _communicate (nova): TRACE: self.wait(timeout=self._remaining_time(endtime)) (nova): TRACE: TypeError: wait() got an unexpected keyword argument 'timeout' Red Hat have backported the 'timeout' feature for subprocess.Popen to Python-2.6.6 in RHEL 6.1. At first glance it looks like they've broken subprocess but infact they haven't - its Eventlet that's causing the problem because its 'wait' function doesn't expect the timeout argument. I've reported the problem upstream here: https://bitbucket.org/which_linden/eventlet/issue/89/add-a-timeout-argument-to-subprocesspopen The patch below fixed the problem for me: --- /usr/lib/python2.6/site-packages/eventlet/green/subprocess.py.orig 2011-05-25 23:31:34.597271402 +0000 +++ /usr/lib/python2.6/site-packages/eventlet/green/subprocess.py 2011-05-25 23:33:24.055602468 +0000 @@ -32,7 +32,7 @@ setattr(self, attr, wrapped_pipe) __init__.__doc__ = subprocess_orig.Popen.__init__.__doc__ - def wait(self, check_interval=0.01): + def wait(self, check_interval=0.01, timeout=None): # Instead of a blocking OS call, this version of wait() uses logic # borrowed from the eventlet 0.2 processes.Process.wait() method. try: -- Dave _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
