[ovirt-users] Changing the ovirtmgmt IP address

Version: 4.3.10 I'm attempting to change the IP address, netmask and gateway of the ovirtmgmt NIC of a host, but everytime I reboot the host, the old address/netmask/gateway re-assert themselves. Where do I need to make the changes, so they will be permanent? I've modified /etc/sysconfig/network-scripts/ifcfg-ovirtmgmt and route-ovirtmgmt, but they don't stick through a reboot.
