[Libvirt-cim] how to set the NetworkType as bridge of vs with libvirt-cim provider

Hi， I want to define a virtual domain with bridge type by libvirt-cim provider. Below is part of code of RASD description, but it fails for me. ... rasd = [ """instance of KVM_MemResourceAllocationSettingData { VirtualQuantity = 256;};""", """instance of KVM_ProcResourceAllocationSettingData { VirtualQuantity = 1;};""", """instance of KVM_NetResourceAllocationSettingData { Address = "00:11:22:33:44:55"; ResourceType = 10; NetworkType='bridge';};""", """instance of KVM_DiskResourceAllocationSettingData { Address = "/tmp/default-kvm-dimage"; VirtualDevice = "hda";};""" ] service.DefineSystem(SystemSettings=vssd, ResourceSettings=rasd, ReferenceConfiguration='') ... It seems that the NetworkType is set network as default in libvirt-cim provider. Although I try to set the NetworkType as bridge, it still to looking up default network pool. If I want to define a vs with bridge type, what should I do? Thanks!
