[Libvir] [PATCH] #4: Change interface between xen_unified & its underlying drivers

[Richard W.M. Jones]

If you recall the current driver model, which looks like this:

     libvirt.c
        |
      (virDriver)
        |
        V
        +---- xen_unified.c
                 |
               (virDriver)
                 |
                 V
                 +---- xen_internal.c
                 |
                 +---- xend_internal.c
                    etc.

The interface between libvirt.c and xen_unified.c is virDriver.  And
currently the same interface is reused between xen_unified.c and its
underlying drivers.

This patch defines a new structure called xenUnifiedDriver, which begins
as a subset of virDriver, and eventually will go away in favour of
direct calls from xen_unified to the underlying parts (much simpler to
understand what's going on that way, and we won't need the current
driver ordering hacks, and anyway the xen drivers call each other
semi-randomly).

     libvirt.c
        |
      (virDriver)
        |
        V
        +---- xen_unified.c
                 |
               (xenUnifiedDriver + direct calls)
                 |
                 V
                 +---- xen_internal.c
                 |
                 +---- xend_internal.c
                    etc.


This patch starts by removing the id, name and version fields from
virDriver.

It also removes getMaxVcpus and the domainLookup* fields, which will
make more sense when you see patches #6 and #7 in this series.

Rich.
