This is the rest of the virConnectListAllDomains() that is not yet merged. I've
rebased it to current upstream and bumped the version numbers.

New subject: [libvirt] [PATCHv5 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.

New subject: [libvirt] [PATCHv5 2/2] esx: Add implementation for virConnectListAllDomains()
Esx doesn't use the common virDomainObj implementation so this patch
adds a separate implementation.
This driver supports all currently defined filtering flags, but as with
other drivers some combinations yield a empty result list.
