[ovs-discuss] DHCP and OVS

[MCGRATH, GIL]

Justin,

Attached is the output of "ovs-dpctl dump-flows system at ovs-system” while I
was pxe booting the VM.
I am not an ovs expert at all - so I hope I did this correctly. The MAC
address of the VM is 52:54:00:45:7b:db

Sorry for the misunderstanding….
