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.

Red Hat Product Errata RHBA-2011:0596 0 normal SHIPPED_LIVE libvirt bug fix and enhancement update 2011-05-18 17:56:36 UTC

Description Justin Clift 2010-06-18 08:29:21 UTC 
Description of problem:

At present when using virsh, the only (non-XML) way to retrieve pool and volume usage information is with the pool-info and vol-info commands.

These commands are functional, but only display information for only one pool or volume at a time, making them impractical for use when dealing with hundreds of volumes.

A patch for fixing this has been submitted upstream:

  http://www.redhat.com/archives/libvir-list/2010-June/msg00458.html

Existing output of pool-list:

  virsh # pool-list
  Name                 State      Autostart 
  -----------------------------------------
  default              active     yes       
  image_dir            active     yes       

  virsh # pool-list --all
  Name                 State      Autostart 
  -----------------------------------------
  default              active     yes       
  image_dir            active     yes       
  tmp                  inactive   no

Comment 2 Justin Clift 2010-06-18 08:45:16 UTC 
The individual patches submitted upstream:

  http://www.redhat.com/archives/libvir-list/2010-June/msg00459.html

Comment 3 RHEL Program Management 2010-06-18 08:55:00 UTC 
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release.  Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release.  This request is not yet committed for
inclusion.
Comment 5 Eric Blake 2010-06-29 16:28:01 UTC 
This will not be applied for RHEL 6.0 (the information can be obtained through other virsh commands, so this was just an RFE), but it is reasonable to include for 6.1.
Comment 7 Jiri Denemark 2010-12-23 23:48:15 UTC 
Fixed by a rebase to libvirt-0.8.6
Comment 9 Nan Zhang 2010-12-24 08:52:09 UTC 
Verified with the following build, the execution result is as expected. Moving it to VERIFIED.
