RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at [email protected] to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description yalzhang@redhat.com 2018-07-24 11:17:38 UTC 
Description of problem:
there is error like "virNWFilterBindingLookupByPortDev:589 : portdev in virNWFilterBindingLookupByPortDev must not be NULL" promoted once the vm is failed to start

Version-Release number of selected component (if applicable):
libvirt-4.5.0-4.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1. set libvirtd log
# rm -fr /var/log/libvirt/libvirtd.log
append below settings into /etc/libvirt/libvirtd.conf
log_level=2
log_outputs='2:file:/var/log/libvirt/libvirtd.log'
 
2. restart libvirtd
# systemctl restart libvirtd
# grep error /var/log/libvirt/libvirtd.log

3. make some changes, to let the vm fail to start, such as:
# virsh net-destroy default
Network default destroyed
# virsh dumpxml rhel | grep /interface -B5
    <interface type='network'>
      <mac address='52:54:00:9b:f2:25'/>
      <source network='default'/>
      <model type='rtl8139'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x0a' function='0x0'/>
    </interface>
# virsh start rhel
error: Failed to start domain rhel
error: Requested operation is not valid: network 'default' is not active

4. check the libvirtd log, there is error about nwfilter
# grep error /var/log/libvirt/libvirtd.log
2018-07-24 11:05:38.015+0000: 7174: error : virNWFilterBindingLookupByPortDev:589 : portdev in virNWFilterBindingLookupByPortDev must not be NULL


Scenario B: 
edit the images to non-exists ones:
# virsh dumpxml rhel | grep /disk -B6
    <disk type='file' device='disk'>
      <driver name='qemu' type='qcow2'/>
      <source file='/var/lib/libvirt/non-exists/RHEL-7.6-x86_64-latest.qcow2'/>
...
    </disk>
# virsh start rhel
error: Failed to start domain rhel
error: Cannot access storage file '/var/lib/libvirt/non-exists/RHEL-7.6-x86_64-latest.qcow2' (as uid:107, gid:107): No such file or directory

# grep error /var/log/libvirt/libvirtd.log
2018-07-24 11:09:14.947+0000: 27080: error : virStorageFileReportBrokenChain:4656 : Cannot access storage file '/var/lib/libvirt/non-exists/RHEL-7.6-x86_64-latest.qcow2' (as uid:107, gid:107): No such file or directory

Scenario C:
set vm with non-exists nwfiler
# virsh dumpxml rhel | grep /interface -B6
    <interface type='network'>
      <mac address='52:54:00:9b:f2:25'/>
      <source network='default'/>
      <model type='rtl8139'/>
      <filterref filter='no-exists'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x0a' function='0x0'/>
    </interface>
# virsh start rhel
error: Failed to start domain rhel
error: internal error: referenced filter 'no-exists' is missing
