All networking within oVirt seems fine. I can ping devices on other networks, I'm able to use a squid proxy on the same network with no issues. I'm able to use Terminal Services from another VM in oVirt. One oddity is when I first boot, I'm able to hit Google and search for a Dog. On my 2nd search it starts to timeout.
All and all ip networking seems to be configured well. The DG lives outside of oVirt and I'm always able to ping it; even increasing the packet size. MTU size is 1500 and matches the VLAN MTU in oVirt; the bond0 is set to set to an 9000 MTU. EM1 and EM2 are in bond0 and show no framing errors.
