Are you volunteering to write some code? :-)
There have been requests for both, and both should eventually be done,
so I guess pick whichever one you like better :-) (since there's already
a patch for VDE, albeit with different XML than we'd like, that may be
quicker to finish.)
You may want to follow development of the work I'll point out below,
though, otherwise you could waste a lot of time.

Once we get into these kinds of questions, it's probably best to switch
to the developers' list (libvir-list(a)redhat.com) to get better exposure
to people writing the code. I'm Cc'ing this message there (and switching
the Reply-To: as well).
In particular, I recently send an RFC to libvir-list proposing an
expansion of the <network> XML to remove the hard-coded connection
between guest interface and host interface for macvtap (type='direct')
interfaces:
https://www.redhat.com/archives/libvir-list/2011-April/msg00591.html
and in a followup message showed how we could expand on this work to
provide support for openvswitch (or vde):
https://www.redhat.com/archives/libvir-list/2011-April/msg00640.html
I'm planning to have this code finished and tested within the next two
months at most (hopefully considerably earlier). If you're interested in
implementing a <network type='openvswitch'> or <network type='vde'> you
should subscribe to libvir-list (if you aren't already) so that you can
follow along.

[libvirt] [PATCH v2] tests: Lower stack usage below 4096 bytes
by Matthias Bolte
Make virtTestLoadFile allocate the buffer to read the file into.
Fix logic error in virtTestLoadFile, stop reading on the first empty line.
Use virFileReadLimFD in virtTestCaptureProgramOutput to avoid manual
buffer handling.
---
v2: rebased to current git head.

by Matthias Bolte
Call shutdown functions for all subcompontents in nwfilterDriverShutdown.
Make sure that this shutdown functions can safely be called multiple times
and independent from the actual subcompontents state.

[libvirt] [PATCH] Fix memory leak in __virExec
by Matthias Bolte
Commit e0d014f2379dd made binary potentially allocated on the heap.
It was freed in the parent in the error path, but not in the success path
that doesn't goto the cleanup label.
Found by 'make -C tests valgrind'.

[libvirt] [PATCH] hash: fix memory leak and regression
by Eric Blake
Commit 1671d1d introduced a memory leak in virHashFree, and
wholesale table corruption in virHashRemoveSet (elements not
requested to be freed are lost).
* src/util/hash.c (virHashFree): Free bucket array.
(virHashRemoveSet): Don't lose elements.
* tests/hashtest.c (testHashCheckForEachCount): New method.
(testHashCheckCount): Expose the bug.

[libvirt] [PATCH v2] util: Simplify hash implementation
by Jiri Denemark
So far first entries for each hash key are stored directly in the hash
table while other entries mapped to the same key are linked through
pointers. As a result of that, the code is cluttered with special
handling for the first items.
This patch makes all entries (even the first ones) linked through
pointers, which significantly simplifies the code and makes it more
maintainable.

* .gnulib: Update to latest, for getaddrinfo fixes.
Reported by Matthias Bolte.
---
As promised, I've done the gnulib side of the mingw cleanups
affecting the issues Matthias found with 0.9.1-rc1.
Oh, and now that gnulib getcwd-lgpl exists, we could use it
to fix our uses of getcwd(NULL,0), followup coming later.
* .gnulib 7d06b32...74175b9 (29):
> getaddrinfo: fix gai_strerror signature
> getsockopt: avoid compiler warning
> tests: drop unused link dependency
> hash, mgetgroups: drop xalloc dependency
> xalloc-oversized: new module
> utimecmp: drop dependency on xmalloc
> getcwd: fix mingw bugs
> Typo in comment.
> mkstemps: Ensure declaration on MacOS X 10.5.
> mkstemp: More documentation.
> mkstemp: Tweak configure message when cross-compiling.
> clean-temp: Clarify what it does.
> fchdir: avoid extra chdir and fix test
> filenamecat-lgpl: fix licence
> linkat, renameat: add missing dependency
> tests: reduce dependencies
> save-cwd: reduce default dependency
> getcwd: enhance tests
> getcwd-lgpl: new module
> getcwd: tweak comments
> mkstemp: replace if system version uses wrong permissions
> passfd: avoid compiler warning

[libvirt] [PATCH] tests: Lower stack usage below 4096 bytes
