[ovirt-users] ovirtmgmt network security

Hello ovirt experts, I'm totally new to ovirt and trying to learn as fast as I can.So, please bear with me and my possibly stupid questions. Sorry if my questions have been answered already, but please point me to the place where I can find the answers. I've setup ovirt 4.1.6 and created a first VM that I want to expose in a DMZ. I attached a dedicated NIC to the VM using passthrough which is connected to the DMZ network. This is all working as expected. Now,I'm wondering what to do about the ovirtmgmt interface. Obviously, in case the security of the VM is compromised and someone get unautorized access to it I do not want the attacker to have access to my internal network through the ovirtmgmt interface. The most secure solution would be to remove that ovirtmgmt interface but then I loose management functionalities. Can you suggest the possible solutions to protect the ovirtmgmt network from unwanted access? Thanks for your answers Istvan
