when trying to install OES2018 via VNC I use the following Boot-Options:

hostip=<ip-Addresse of the new server> netmask=<Subnetmask>
gateway=<IP-Addresse of the gateway> vnc=1 vncpassword=<Password>

This works until OES2015SP1 as designed. But with OES2018 the installer
use a IP-Address from the DHCP-Pool instead.

I tested this with VMware and KVM.

Any recommends?
