Hello, new user here!
I've noticed that the virtual interface ovirtmgmt gets an IP address by
DHCP.
Is there any good way to make it static instead?
I've seen a workaround which is basically:
run hosted-engine --deploy
Let it configure the management interface.
Cancel
Change the IP adress to static in:
/etc/sysconfig/network-scripts/ifcfg-ovirtmgmt
Run hosted-engine --deploy again.
Would this be the current appropriate solution?
Also, is it possible to change this later on, after the installation is
finished?
I would appreciate any assistance.
With my best regards

I'd encourage an answer to this topic.
I didn't dive into hosted engine
yet myself but when I do, I'll start
with a static ip too.
So it seems a little strange to just
support dhcp.
I think there must be a way for static
networking too.

I agree Sven, and you probably missed my response ;)
The simple answer is that there are endless networking typologies and configurations,
so most admins would first configure the relevant networking and only then install
additional software (ovirt in this case).
See my other reply, and let's discuss it there if needed.

Hi Klas,
the installer is using an existing interface for the bridge.
The idea is that an administrator would first configure the host networking
and only then download and install the software.
We have many cases where admins use vlans and bonds, and static IP is probably
the easiest case ;)
So the right way is to first configure your eth/em interface with your networking
preferences (static IP in this case), and then yum install hosted engine.
Yes, it is possible to change it during the process and afterwards (need to shut down
relevant services) but the best way is configuring network first.

You can configure with static IP the interface that you're going to use for the
bridge.
hosted-engine --deploy will preserve the static ip configuration while creating the
bridge.

run hosted-engine --deploy
Let it configure the management interface.

See above.

You'll need working network during the setup process in order to validate gateway and
fqdn.
That said, once the hosted engine is deployed you can change network configuration.
Just be sure to call vdsClient -s 0 setSafeNetworkConfig in order to be sure that VDSM
won't restore previous configuration.
I would appreciate any assistance.
With my best regards
