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.

    conf: storage: Add volume feature formatter for gluster pools
    
    Libvirt didn't output feature flags for images stored on native gluster.
    Fix this trivially by adding a feature formatter callback.

Comment 3 Xuesong Zhang 2014-12-23 11:14:30 UTC 
Verify this bug with the following package version:
libvirt-1.2.8-11.el7.x86_64
qemu-img-rhev-2.1.2-17.el7.x86_64
kernel-3.10.0-219.el7.x86_64 

Steps:
1. prepare one gluster pool, there is one volume is qcow2v3 format.
# virsh pool-list 
 Name                 State      Autostart 
-------------------------------------------
 default              active     yes       
 gluster-pool         active     no        

# virsh vol-list gluster-pool
 Name                 Path                                    
------------------------------------------------------------------------------
 qcow3                gluster://#glusterServerIP#/gluster-vol1/qcow3
 test.qcow2           gluster://#glusterServerIP#/gluster-vol1/test.qcow2
 test.raw             gluster://#glusterServerIP#/gluster-vol1/test.raw

2. checking the vol-dumpxml of the qcow2v3 format volume, the "<lazy_refcounts/>" is there as expected.
# virsh vol-dumpxml qcow3 gluster-pool
<volume type='network'>
  <name>qcow3</name>
  <key>gluster://#glusterServerIP#/gluster-vol1/qcow3</key>
  <source>
  </source>
  <capacity unit='bytes'>1073741824</capacity>
  <allocation unit='bytes'>197120</allocation>
  <target>
    <path>gluster://#glusterServerIP#/gluster-vol1/qcow3</path>
    <format type='qcow2'/>
    <permissions>
      <mode>0600</mode>
      <owner>0</owner>
      <group>0</group>

      <mtime>1419333063.285934984</mtime>
      <ctime>1419333063.285934984</ctime>
    </timestamps>
