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.

Libvirt will create the directory, but it cannot change the uid:gid to 0:0.
I've sent a patch changing the error from 'Unknown error' to 'Permission denied:

Tested this one with libvirt-1.2.8-6.el7.x86_64.

1.$vi pool.xml
<pool type='dir'>
  <name>default1</name>
  <capacity unit='bytes'>0</capacity>
  <allocation unit='bytes'>0</allocation>
  <available unit='bytes'>0</available>
  <source>
  </source>
  <target>
    <path>/tmp/images</path>
    <permissions>
      <mode>0644</mode>
      <owner>0</owner>
      <group>0</group>
    </permissions>
  </target>
</pool>

2.define it
$ virsh pool-define pool.xml
Pool default1 defined from pool.xml

3.make sure no dir
$ ll /tmp/images
ls: cannot access /tmp/images: No such file or directory

4. $ virsh pool-build default1
error: Failed to build pool default1
error: cannot create path '/tmp/images': Operation not permitted

5. $ ls -l /tmp
drw-r--r--.  2 yangyang yangyang         6 Nov 11 18:56 images

Per comment #2, the uid/gid of /tmp/images are not set and error message is fixed, mark it as verified.
