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.

    storage: pool: Fix handling of errors on pool lookup failure
    
    Rework internal pool lookup code to avoid printing the raw UUID buffer
    in the case a storage pool can't be found:
    
     $ virsh pool-name e012ace0-0460-5810-39ef-1bce5fa5a4dd
     error: failed to get pool 'e012ace0-0460-5810-39ef-1bce5fa5a4dd'
     error: Storage pool not found: no storage pool with matching uuid à¬à`X9ï_¥¤Ý
    
    The rework is mostly done by switching the lookup code to the newly
    introduced helper virStoragePoolObjFromStoragePool

qemu-kvm-rhev-2.1.2-15.el7.x86_64
kernel-3.10.0-210.el7.x86_64

steps:
1.prepare a pool
# virsh pool-list --all
 Name                 State      Autostart 
-------------------------------------------
 default              active     yes       
 dir-pool             active     no  

2.get pool info 
# virsh pool-info dir-pool
Name:           dir-pool
UUID:           6de65198-b660-4cf1-a1c9-c3a8e228b9a9

Allocation:     4.01 GiB
Available:      95.94 GiB

3.get pool name from correct uuid
# virsh pool-name 6de65198-b660-4cf1-a1c9-c3a8e228b9a9
dir-pool

4.try to get pool name from no-exist pool uuid

# virsh pool-name 6de65198-b660-4cf1-a1c9-123456789098
error: failed to get pool '6de65198-b660-4cf1-a1c9-123456789098'
error: Storage pool not found: no storage pool with matching uuid '6de65198-b660-4cf1-a1c9-123456789098'

5. check volume using correct pool uuid 
# virsh vol-list 0f5a73bc-a7bc-4639-a172-9bd0989e2c85
 Name                 Path                                    
------------------------------------------------------------------------------
 vol1                 /tmp/dir-pool/vol1                      

6. check volume with no-exist pool uuid 
# virsh vol-list 0f5a73bc-a7bc-4639-a172-123456789098
error: failed to get pool '0f5a73bc-a7bc-4639-a172-123456789098'
error: Storage pool not found: no storage pool with matching name '0f5a73bc-a7bc-4639-a172-123456789098'
