Re: [Users] How to add internal networks

Hello Frank, I suspect the problem is that VDSM isn't told by default to pass dummy NICs on to the engine. Have a look at the following file (exact path might vary): /usr/lib64/python2.7/site-packages/vdsm/config.py Search for a variable called "fake_nics", it should exist for 3.2. By default it is empty, but you may define a pattern for fake NIC names to be passed to the engine (in your case probably "dummy*"). Restart the vdsm daemon and everything should be fine. Maybe you'll have to move the host to maintenance and then reactivate just to refresh the UI. Please let us know if that works. Yours, Lior.
