Hello, I pulled the latest changes from master to test my code and during getCaps I got: Thread-14::ERROR::2014-04-28 12:11:44,394::__init__::484::jsonrpc.JsonRpcServer::(_serveRequest) [Errno 2] No such file or directory Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/yajsonrpc/__init__.py", line 480, in _serveRequest res = method(**params) File "/usr/share/vdsm/Bridge.py", line 211, in _dynamicMethod result = fn(*methodArgs) File "/usr/share/vdsm/API.py", line 1184, in getCapabilities c = caps.get() File "/usr/share/vdsm/caps.py", line 459, in get caps['numaNodeDistance'] = _getNumaNodeDistance() File "/usr/lib64/python2.7/site-packages/vdsm/utils.py", line 1003, in __call__ value = self.func(*args) File "/usr/share/vdsm/caps.py", line 209, in _getNumaNodeDistance retcode, out, err = utils.execCmd(['numactl', '--hardware']) File "/usr/lib64/python2.7/site-packages/vdsm/utils.py", line 732, in execCmd deathSignal=deathSignal, childUmask=childUmask) File "/usr/lib64/python2.7/site-packages/cpopen/__init__.py", line 50, in __init__ stderr=PIPE) File "/usr/lib64/python2.7/subprocess.py", line 711, in __init__ errread, errwrite) File "/usr/lib64/python2.7/site-packages/cpopen/__init__.py", line 80, in _execute_child_v275 self._childUmask) OSError: [Errno 2] No such file or directory When I installed numactl rpm getCaps work again. Do we need to add this dependency to spec file? Thanks, Piotr
