Re: [ovirt-users] Change ovirtmgmt ip from dhcp to static in a

[zois roupas]

Is this a safe procedure? I mean i only have this host in my cluster, what will 
happen at the vm's that are assigned to the host?


Thanks again

Then you need to remove the host from engine, change the IP manually on the 
host, via ifcfg-file, restart network service and install the host again via 
the new IP address.

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

Ales, i also tried to follow your advise and uncheck the "Verify connectivity

Great step by step instructions but something strange is happening while trying

If you changing the host's management IP address then this is the only way
to do it. If you have only one host in the cluster, then you will need to
shut them down :(

Indeed very odd, this shouldn't  behave this way, just tested it my self
and it is working as expected. Unless i miss understood you here, do you
use a different IP address when switching to static or the same IP that you

Hello Zois,

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.

- 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.

- 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.

Cheers)

[ovirt-users] Change ovirtmgmt ip from dhcp to static in a

[zois roupas]

Hello everyone


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 worked so 
well that i kept configuring and installing vm's ,adding local and nfs storage 
and setting up the backup!

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?

I've found this thread 
http://lists.ovirt.org/pipermail/users/2014-May/024432.html but this is for a 
hosted engine and doesn't help when both engine and host are in the same machine


Thanx in advance

Best Regards

Zois
