Yet another respin updated and rebased to current head.
Both drivers are compile tested but I don't have the infrastructure do a
functional test.

New subject: [libvirt] [PATCHv6 1/2] hyperv: Add implementation for virConnectListAllDomains()
Hyperv doesn't use the common virDomainObj implementation so this patch
adds a separate implementation.
This driver supports all currently added flags for filtering although
some of those don't make sense with this driver (no support yet) and
thus produce no output when used.

ESX doesn't use the common virDomainObj implementation so this patch

This driver supports all currently defined filtering flags, but as with
other drivers some combinations yield a empty result list.

Yep, let's just test it in the wild :). I corrected a bug that would
create empty lists on ESX if some filters were used that I found during
a last self-review and pushed the series. Thanks.

And here comes your in-the-wild testing :)
Sorry for not taking care of this earlier.
Both patches look quite well, but there are some small problems and
possibilities for improvement. I've posted two patches for this:
https://www.redhat.com/archives/libvir-list/2012-September/msg00486.html
https://www.redhat.com/archives/libvir-list/2012-September/msg00485.html
The Hyper-V patch is not runtime tested yet because I currently have
some trouble getting my Hyper-V setup to work again. I'll report back
on this once I get it running.
