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.

Agreed.

    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>
