<div>To answer your question Michael , i'm trying to configure a different ip outside of my dhcp pool. The dhcp ip is 10.0.0.245 from the range 10.0.0.245-10.0.0.250 and i want to configure the ip 10.0.0.9 as the hosts ip</div>

<div>Hello Zois,<br>
<br>
</div>
It pretty easy to do, via the webadmin UI , go to Hosts main tab > Choose host > go to 'Network Interfaces' sub tab > Press the 'Setup Host Networks' button > press the pencil icon on your management network > and choose Static IP > press OK and OK to approve
the operation.<br>
<br>
</div>
- Note that in some cases, specially if this is a SPM host you will loose connectivity to host for few seconds and host may go to non-responsive state, on a non-SPM host usually this woks without any specific issues.
<br>
<br>
</div>
- If the spoken host is a SPM host, I recommend to set it first to maintenance mode, do the switch and then activate. For non-SPM host this will work fine as well when the host is UP.
<br>
<br>

<p style="margin-top:0px; margin-bottom:0px">I've made a rookie mistake by installing ovirt 4.2 in centos 7 with dhcp instead of a static ip configuration. Both engine and host are in the same machine cause of limited resources and i was so happy that everything

<p style="margin-top:0px; margin-bottom:0px">As you understand i must change the configuration to static ip and i can't find any guide describing the correct procedure. Is there an official guide to change configuration without causing any trouble?</p>
