In order to pass DHCP request to a vendor’s server and send DHCP response back to VM we decided to add another OVS bridge (we called it br-dhcp), connected to integration bridge (br-int), which will have OVS rules connecting VM’s MAC address with br-dhcp port. In this scenario DHCP response will only find it’s way back to a VM if VM has globally-unique MAC address. </div><div><br></div><div>My questions are: </div><div><ul class="MailOutline"><li>is having code which generates globally-unique MACs for VMs acceptable by the community at all?</li><li>is there a better solution to the problem (we also tried using dnsmasq as a DHCP relay there)?</li></ul><div><br></div></div><div>Thanks,</div><div>Roman</div></body></html>
