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 rh-issues@redhat.com 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 of problem:



Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. virsh nodedev-list pci 
2. Using an entry from the list (and not pci_0000_00_00_0):
   virsh nodedev-dumpxml <entry>

Actual results:

1.  virsh nodedev-list pci
pci_0000_00_00_0
pci_0000_00_01_0
pci_0000_00_02_0

Comment 3 Xuesong Zhang 2017-11-27 07:08:30 UTC 
hi, John,

It seems this BZ is duplicated with one BZ QE found before, which is BZ 1509805.

    nodedev: Restore setting of privileged
    
    Commit id '36555364' removed the setting of the driver->privileged,
    which the udevProcessPCI would need in order to read the PCI device
    configs.
