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.

Comment 2 Eric Blake 2013-06-06 02:58:31 UTC 
Still needs fixing upstream, but should be relatively easy to reproduce and thus locate the bug.
Comment 4 Eric Blake 2013-07-10 20:59:37 UTC 
Right now, libvirt documents that it refuses to delete external snapshots only because it is not implemented safely; this bug represents a hole where we aren't following the documentation.  Alternatives are to patch code to match docs (quick), or to actually implement snapshot deletion (longer, but more desirable).  I see no need to do a quick patch now only to undo it later when true snapshot deletion is implemented.

Comment 9 Shanzhi Yu 2014-11-14 09:19:42 UTC 
Change to VERIFIED status. Steps as below:

# virsh snapshot-create-as rh7 internal
Domain snapshot internal created
# virsh snapshot-create-as rh7 external --disk-only
Domain snapshot external created
# virsh snapshot-delete rh7 internal --children
error: Failed to delete snapshot internal
error: unsupported configuration: deletion of 1 external disk snapshots not supported yet
# virsh snapshot-delete rh7 internal --children-only 
error: Failed to delete snapshot internal
error: unsupported configuration: deletion of 1 external disk snapshots not supported yet
