I have installed the first node of a new oVirt 3.5 setup with a hosted engine VM. I have multiple networks: one public-accessible and one private (with storage, iDRAC/IPMI, etc.). I set the engine VM up on the public LAN, but now realize that it can't access the power control. I tried to add a second NIC to the engine VM through the web interface, but of course that doesn't work (because it isn't really managed there). How can I add a second NIC to the hosted engine VM?

From the web admin:

I duplicated the existing "devices={nicModel:pv,macAddr” line and modified the macAddr and deviceId entries. Be sure you modify this file on ALL of your ha engine hosts. Then shutdown your running engine, let ha-agent restart it (hosted-engine —vm-start works fine too) and you’ve got two nics. -Darrell > On Nov 14, 2014, at 9:11 AM, Chris Adams <cma(a)cmadams.net&gt; wrote: > > I have installed the first node of a new oVirt 3.5 setup with a hosted > engine VM.

Sorry, I forgot you cannot add that nic on the engine VM from the engine UI. Please try what I explained plus Darrel's trick.

Glad it worked. Make sure you add it to the vm.conf file on all your ha hosts, otherwise you’ll drop it if ha-agent restarts it as opposed to a migration. Wasn’t clear if you’d done that or not.
