Hi all:
I'm facing problems trying to define a bridge on Ubuntu 16.04, using libvirt 3.4.0.
When I try to do:
root@ubuntu-180:/tmp# virsh iface-define iface-testbr1.xml
I get the following error:
error: Failed to define interface from iface-testbr1.xml
error: this function is not supported by the connection driver: virInterfaceDefineXML
It's supported by the netcf interface backend.
What does "virsh -V" tell you?
In the "Networking:" line you'd see 'Interface netcf' - I have to
assume
you have 'udev' instead.
What can i do to make this function works normally? THX.
If netcf isn't supported on Ubuntu, then that's a packaging thing.

The xml file as:

<link speed='1000' state='up'/>
<mac address='0c:c4:7a:c1:63:17'/>

</bridge>
