The Patch has been sent to upstream and wait for review: https://www.redhat.com/archives/libvir-list/2012-February/msg00764.html In fact, now we can move to POST: http://post-office.corp.redhat.com/archives/rhvirt-patches/2012-March/msg02003.html packages: libvirt-0.9.10-8.el6.x86_64 qemu-kvm-0.12.1.2-2.265.el6rhev.x86_64 kernel-2.6.32-252.el6.x86_64 libvirt-python-0.9.10-8.el6.x86_64 Follow the steps in description. result: ==8464== LEAK SUMMARY: ==8464== definitely lost: 0 bytes in 0 blocks ==8464== indirectly lost: 0 bytes in 0 blocks ==8464== possibly lost: 6,152 bytes in 13 blocks ==8464== still reachable: 1,243,298 bytes in 10,245 blocks ==8464== suppressed: 0 bytes in 0 blocks So, this is fixed now. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description of problem: Memory leak on libvirt_virNodeGetCPUStats API. Version-Release number of selected component (if applicable): libvirt-python-0.9.9-0rc1.el6.x86_64.rpm How reproducible: always Steps to Reproduce: 1. Paste the following codes into test.py: import libvirt con = libvirt.open(None) dom = con.lookupByName('foo') con.getCPUStats(0, 0) 2. valgrind -v --leak-check=full python test.py Actual results: ==15786== 160 bytes in 4 blocks are definitely lost in loss record 1,525 of 2,083 ==15786== at 0x4A05FDE: malloc (vg_replace_malloc.c:236) ==15786== by 0x39E1A85EC3: PyObject_Malloc (obmalloc.c:935) ==15786== by 0x39E1A77831: _PyLong_New (longobject.c:75) ==15786== by 0x39E1A79E2E: PyLong_FromUnsignedLongLong (longobject.c:892) ==15786== by 0xB8FC2B4: libvirt_virNodeGetCPUStats (libvirt-override.c:2323) ==15786== by 0x39E1ADE7F3: PyEval_EvalFrameEx (ceval.c:3794) ==15786== by 0x39E1ADF99E: PyEval_EvalFrameEx (ceval.c:3880) ==15786== by 0x39E1AE0466: PyEval_EvalCodeEx (ceval.c:3044) ==15786== by 0x39E1AE0541: PyEval_EvalCode (ceval.c:545) ==15786== by 0x39E1AFB88B: run_mod (pythonrun.c:1351) ==15786== by 0x39E1AFB95F: PyRun_FileExFlags (pythonrun.c:1337) ==15786== by 0x39E1AFCE4B: PyRun_SimpleFileExFlags (pythonrun.c:941) ==15786== ==15786== 180 bytes in 4 blocks are definitely lost in loss record 1,536 of 2,083 ==15786== at 0x4A05FDE: malloc (vg_replace_malloc.c:236) ==15786== by 0x39E1A85EC3: PyObject_Malloc (obmalloc.c:935) ==15786== by 0x39E1A9053C: PyString_FromString (stringobject.c:138) ==15786== by 0xB8FC2C3: libvirt_virNodeGetCPUStats (libvirt-override.c:2323) ==15786== by 0x39E1ADE7F3: PyEval_EvalFrameEx (ceval.c:3794) ==15786== by 0x39E1ADF99E: PyEval_EvalFrameEx (ceval.c:3880) ==15786== by 0x39E1AE0466: PyEval_EvalCodeEx (ceval.c:3044) ==15786== by 0x39E1AE0541: PyEval_EvalCode (ceval.c:545) ==15786== by 0x39E1AFB88B: run_mod (pythonrun.c:1351) ==15786== by 0x39E1AFB95F: PyRun_FileExFlags (pythonrun.c:1337) ==15786== by 0x39E1AFCE4B: PyRun_SimpleFileExFlags (pythonrun.c:941) ==15786== by 0x39E1B094CE: Py_Main (main.c:577) Expected results: Fix memory leaks.
