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.

Fixed In Version: libvirt-0.9.2-1.el6
Doc Type: Bug Fix
Doc Text:
Libvirt was previously using undocumented command line options, instead of the recommended ones during its use of the qemu-img utility. But the fix to have libvirt use the updated command line options introduced a regression that prevented the creation of an encrypted volume. With this update, the bug in qemu-img command line arguments has been fixed, and encrypted volumes can now be created as expected.

In POST with minimal patch, rather than full upstream backport:

Comment 5 Daniel Veillard 2011-06-23 03:40:26 UTC 
This should be fixed for RHEL-6.2 by the libvirt-0.9.2-1.el6 rebase,

Due to a regression, libvirt used undocumented command line options, instead of the recommended ones. Consequently, the qemu-img utility used an invalid argument while creating an encrypted volume, and the process eventually failed. With this update, the bug in the backing format of the storage back end has been fixed, and encrypted volumes can now be created as expected.
Comment 11 Dave Allan 2011-08-22 17:05:19 UTC 
Eric, is that a fair summary?

> Eric, is that a fair summary?

I tweaked the wording.  The key point was that the earlier fix to avoid undocumented command lines introduced the regression the prevented use of encryption.
