Description smitterl 2020-06-09 09:52:11 UTC

Description of problem:
List of nodedev is not populated correctly.

Version-Release number of selected component (if applicable):
libvirt-daemon-6.0.0-17.module+el8.3.0+6423+e4cb6418.s390x

How reproducible:
99%


Steps to Reproduce:
1. systemctl stop libvirtd
2. virsh nodedev-list --cap net

Actual results:
empty


Expected results:
List of net devices, that is, whatever is displayed if 2. is repeated, e.g.
net_enc600_1a_79_fe_a2_82_fd
net_lo_00_00_00_00_00_00
net_virbr0_nic_52_54_00_4d_4f_f4

Additional info:
a.) Fix is available upstream https://gitlab.com/libvirt/libvirt/-/commit/008abeb03c262149b756ad5a226ff6cbc5e37e2c
b.) s390x doesn't have AV
c.) This causes false negatives for tp-libvirt virsh.nodedev_dumpxml.positve_test.acl_test.device_type_net
