Quite literally just done this. Put a host in maintenance Remove the host from the cluster/ovirt engine. Edit the network interface from terminal Edit both files in /var/lib/vdsm/persistence/nets/ovirtmgmt And /var/lib/vdsm/staging/nets/ovirtmgmt Edit the hosts file in /etc/hosts with new IP address Reboot host. Do the same on the second host Re-add hosts to ovirt management Sent from my iPhone

 Hello,

I have a Dell VRTX with 2 M640 servers, we installed oVirt version 4.3.10.4-1.el7, we have 1 cluster, 2 hosts and 2 storage domains.

I need to change ALL the network environment solution, that is, from IP's 192.168.11.XX to 172.16.10.XX.

Can anybody help me?

Thank you.
