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