Hello, I just upgraded my oVirt 3.5.1 install to 3.6. I have a self-hosted engine setup all on a single server. I make use of dummy interfaces for internal networks for my various labs/testing setups. Normally I edit the following file: /usr/lib/python2.7/site-packages/vdsm/config.py I then go to the variable 'fake_nics' and add 'dummy*", so it looks like this: ('fake_nics', 'dummy_*,veth_*,dummy*', ), After I added my entry, I even restarted the whole server (which restarts the VDSM on the host as well as the engine VM), but when I go into the "Network Interfaces" on the host the dummy interfaces are not showingup. Are dummy interfaces still supported in 3.6? I see a feature called "Isolated Networks" in 3.6; is this essentially a replacement? The Features page is a bit confusing to me on how to create an isolated network? Thanks! Regards, Alan
