Hello,
thank you for your patience for trying to let me see the light.
Indeed I don't understand what you are explaining. Maybe if I give you more concrete details it will help.
My internal network is 192.168.196.0 My DMZ network is 192.168.188.0
ovirt-engine is running on a centos server with IP 192.168.186.3 ovirt host is on a centos server with IP 192.168.186.4
On the host I created a VM that I want to be in the DMZ. When I created the VM, nic 1 was automatically added and is linked to the ovirtmgmt network. In the VM nic1 becomes eth0 and was assigned an IP address with DHCP 192.168.186.167.
After that I added a host device to that VM using passthrough. This device is called ens7 in the VM and I gave IP 192.186.188.4. That device is directly connected to my physical DMZ switch and from there to the firewall. This part is OK.
My problem is that through eth0 my VM has access to my internal network. Removing the device seems impossible because this is ovirtmgmt network. I can not change or remove the IP of my host because it would not be reachable anymore on my internal network.
Maybe the solution is obvious but I can't see it. I'm running in circle with this problem and it makes me crazy.
Hi Istvan, why are you using device passthrough? Anyway. If you don't need the VM to access to ovirtmgmt, remove nic1. As far as i can understand, you're directly communicating through DMZ.
