Hi Tiemen, have you checked for general network setup issues? Sorry, can only guess here.
To check oVirt I suggest to create another VM with a DHCP server. Example: I recently had quite the same problem - it turned out the DHCP server used the wrong gateway. Vlans where configured routed in the switch; thus the DHCP requests reached the server while the offers were not send back via the same gateway.
