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 2011-09-27 12:03:43 UTC 
This is cosmetic.  Although I have a v1 upstream series proposed (and am working on v2 to address the comments raised), I do not think that backporting 14 patches for a cosemetic-only reason is appropriate this late in RHEL 6.2 development.  I'd prefer to defer this to 6.3.

    snapshot: indent domain xml when nesting
    
    <domainsnapshot> is the first public instance of <domain> being
    used as a sub-element, although we have two other private uses
    (runtime state, and migration cookie).  Although indentation has
    no effect on XML parsing, using it makes the output more consistent.
    
    This uses virBuffer auto-indentation to obtain the effect, for all
    but the portions of <domain> that are not generated a line at a
    time into the same virBuffer.  Further patches will clean up the
    remaining problems.
Comment 8 zhpeng 2012-01-10 03:24:40 UTC 
Test it with:
libvirt-0.9.9-1.el6.x86_64

And the xml is the respected result.

<domainsnapshot>
  ...
  <domain type='kvm'>
  ...
  </domain>
</domainsnapshot>
