[libvirt] [PATCH 0/6] RelaxNG improvements for virStorageSource

[Eric Blake]

Part of extending the domain XML to show an entire backing chain
is splitting the RelaxNG definitions so that the portion related
to a single source within the chain can easily be reused.

I'm still debating about the way to handle storage volumes using
<format type='qcow2'/> vs. domain disks using <driver name='qcow2'
type='qcow2'/>.  The majority of the <driver> attributes are
associated with the one disk device presented to the guest, rather
than attributes for a file in the chain.  So I'm thinking of
having domain disks add a new <format> element; where we output
the format under both elements but accept either spelling for
new input (back-compat reasons require that we always provide
the old spelling).

Eric Blake (6):
  conf: create common storage RNG grammar file
  conf: better <disk> interleaving in schema
  conf: tighten <domainsnapshot> schema
  conf: split <disk> schema into more pieces
  conf: move storage source details to common RNG file
  conf: move <auth> and <encryption> to disk source
