Yes, if your network team would assign an IP for that MAC, e.g. for static assignment inside the virtual machine or via DHCP. Please note that oVirt allows you to manage the MAC addresses of the VMs. (With the exception of external networks like OVN or OpenStack Neutron networks) oVirt's VM networking is focused on layer 2, and does not care about layer 3 issues like IP address management and routing. I could image that there are some less straight forward solutions like cloudinit, or a script inside the VM possible, but I would prefer to manage the IP addresses outside the guests, e.g. by a DHCP server. Straight forward would be the use a DHCP server for IP address management. A simple way would be to use a DHCP server of your host management network. The host management network is represented by the logical network "ovirtmgmt" in oVirt. This DHCP server is probably managed by your network team. A more complex way would be to create a dedicated VLAN on layer 2, represented in oVirt by a new logical network with a VLAN tag. All the VDI VMs could be attached to this new logical network and a dedicated node could provide higher layer services like a DHCP server and IP routing between the new VLAN and the host management network. This node could be a usual physical router, or a oVirt VM, with access to both layer 2 networks. Please note that the already existing routers have to learn about the new network, if the VDI clients cannot added to the new VLAN.
