Note that in general we don't promise *any* API is supported by *any*
URI. The set of APIs provided by any given driver are documented in
our page
https://libvirt.org/hvsupport.html
So the fact that the network:/// URI doesn't support the listing
of domains is not a bug. It is just an expected gap in the support
matrix for that driver.
IOW, this is largely a documentation task - I still need to provide
docs for the secondary drivers to describe this better.
