This change isn't that easy, as you will loose connectivity from oVirt 
to your hosts and have to change patch cables. I would do the following:
- configure 192.168.1.x ip on oVirt engine and keep 10.1.2.x address
- put first host into maintenance mode
- configure network on host on CLI to match your requested situation and 
patch host accordingly
- edit host and change IP address to 192.168.1.x (or if you're using 
DNS-Name/hosts-entry for host communication change this)
- check/refresh network configuration in network tab of this host
- activate host
- repeat steps for all other hosts

As your private ovirtmgmt network is properly not routed, I suggest to 
add a display network which is the 10.1.2.0/xx network or use Spice 
proxy in order to be able to connect to vm consoles.

Maybe there is an easier way to change your network setup - I would do 
it as described above...

René
