My lack of Linux proficiency is going to show here, but..

I guess I'm a bit confused on how to correctly configure my network interface(s) for oVirt.

I currently have two network interfaces:

enp0s25 -

This is my Ethernet interface, but it is unused.  It currently is set to DHCP and has no IP address.  However, it is the only interface that oVirt suggests I use when configuring which nic to set the bridge on.

wlo1 - 

My wireless interface, and IS how i'm connecting to the internet.  This is the IP address that I was using in my /etc/hosts file.

Is it it not possible have a system that can run oVirt as well as maintain an internet connection?

oVirt by default works in bridge mode.

This means that is going to create a bridge on your hosts and the vnic of your VMs will be connected to that bridge as well.

oVirt is composed by a central engine managing physical hosts trough an agent deployed on each host.

So the engine has to be able to reach the managed hosts, this happens though what we call management network.

hosted-engine is special deployment where for ha reasons the oVirt engine is going to run on a VM hosted on the host that it's managing.

So, wrapping up, with hosted-engine setup you are going to create a VM for the engine, the engine VM will have a nic on the management network and this mean that you have a management bridge on your host.

The host has to have an address over the management network in order to have the engine able to reach your host.

That's why hosted-engine-setup is checking the address of the interface you choose for the management network.

Hi Marton,

Here is the log: https://gist.github.com/anonymous/ac777a70b8e8fc23016c0b6731f24706

You tried to create the management bridge over enp0s25 but it wasn't configured with an IP address for your host.

Could you please configure it or choose a correctly configured interface?

Hi Jon,

  There will be people on this list far more able to help you than I can, but the contents of the engine setup log (/var/log/ovirt-hosted-engine-setup/ovirt-hosted-engine-setup-20170614160653-2vuu7h.log) would help

This is roughly my 10th attempt at installing some version of oVirt and I think where I get stuck every time is with the networking aspect.

I'm simply trying to test out oVirt on an old laptop wiht 16GB RAM and an external HDD.  I'm connected via WiFi.

After failing 100 times with the regular ovirt engine, It was recommended I try the self-hosted engine.

**

Anyway, here are the contents of my /etc/hosts file:

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4

::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

10.114.13.144 host.example.rocks host

10.114.13.145 engine.example.rocks engine

**

After running hosted-engine --deploy, I get to the prompt below in which the installer fails afterwards:

You may specify a unicast MAC address for the VM or accept a randomly generated default [00:16:3e:5b:3a:73]:

This is my first time writing to this list, so hopefully I'm doing it right.  Thanks in advance - this is driving me crazy!
