The problem with implementing ESX networking support in libvirt is
that ESX's and libvirt's network model don't match directly and it's
not entirely clear how two map those two in a useful way.
Can you be more specific about what you need in terms of network management?
Sorry if I did not make it clear. For commands, I meant the net-list, net-destroy, etc commands in virsh.
I am actually using the libvirt Python-bindings to write scripts which automate the VM creation process. All I need in terms of network management is that I want it to have two interfaces eth0 and eth1 with static ip addresses(gateway, subnet, etc), so I don't need any other extra configuration such as virtbr0 provided by libvirt/libvirtd daemon. Is there any way to prevent libvirtd daemon being installed on the guest VM?

are you doing that?
Matthias
No. I am running libvirt with its Python-bindings on a Ubuntu PC, and remotely creating VMs on ESX server. Since I am creating VMs on ESX server, I don't really need libvirtd. It would be nice if I can disable libvirtd before it's being installed on VMs.
Thanks so much for your help,
Jake
