Description lcheng 2019-12-30 06:06:30 UTC

Description of problem:
listAllPorts() cann't list all network ports.

Version-Release number of selected component (if applicable):
python3-libvirt-5.10.0-1.module+el8.2.0+5145+c579b816.x86_64
libvirt-5.10.0-1.module+el8.2.0+5135+ed3b2489.x86_64

How reproducible:
100%

Steps to Reproduce:
# python
Python 3.6.8 (default, Dec  5 2019, 15:45:45) 
[GCC 8.3.1 20191121 (Red Hat 8.3.1-5)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import libvirt
>>> conn = libvirt.open()
>>> net = conn.networkLookupByName("default")
>>> port_list = net.listAllPorts()
>>> port_list
[<libvirt.virNetwork object at 0x7f978e547550>, <libvirt.virNetwork object at 0x7f978e547ac8>]
>>> port_list[0].XMLDesc()
libvirt: Network Driver error : invalid network pointer in virNetworkGetXMLDesc
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib64/python3.6/site-packages/libvirt.py", line 3063, in XMLDesc
    if ret is None: raise libvirtError ('virNetworkGetXMLDesc() failed', net=self)
libvirt.libvirtError: invalid network pointer in virNetworkGetXMLDesc


Actual results:
listAllPorts() get a libvirt.virNetwork object list.

Expected results:
listAllPorts() get a libvirt.virNetworkPort object list.

Additional info:
Repeat listAllPorts() will get following error.

>>> port_list = net.listAllPorts()
libvirt: Network Driver error : invalid network pointer in virNetworkFree
>>> port_list = net.listAllPorts()
libvirt: Network Driver error : invalid network pointer in virNetworkFree
libvirt: Network Driver error : invalid network pointer in virNetworkFree
>>> port_list = net.listAllPorts()
libvirt: Network Driver error : invalid network pointer in virNetworkFree
libvirt: Network Driver error : invalid network pointer in virNetworkFree
