I am closing this ticket as not a bug. The system team built OVS from wrong branch (without IPAM handling code). |
Description of problem: On a clean oVirt environment with RHEL 7.3 servers, OVS version: 2.6.1-1 and the latest OVN provider RPM's from the experimental oVirt repository, a VM attached to OVN network with subnet fails to obtain IP address from DHCP. Using OVS version: 2.6.90-1 and older RPM versions of ovirt-provider-ovn and ovirt-provider-drivers it used to work as expected. Version-Release number of selected component (if applicable): Non-working OVS version: openvswitch-2.6.1-1.el7.x86_64 Working OVS version: openvswitch-2.6.90-1.fc24.x86_64 oVirt Engine version: 4.1.0-0.2.master.20161201131309.git6c02a32.el7.centos Vdsm version: vdsm-4.18.999-1028.gitd5c00b9.el7.centos How reproducible: 100% Steps to Reproduce: 1. Install OVN on three machines: - oVirt engine 4.1 with oVirt Provider OVN package installed. - Two oVirt Vdsm hosts with oVirt Provider OVN driver package installed. 2. Use vdsm-tool ovn-config {provider_ip} {host_ip} on each driver server, to setup the OVN tunnel. 3. Create OVN network with subnet configuration: CIDR: 192.168.10.0/24, GW: 192.168.10.254 and DNS: 8.8.8.8 4. Add extra vNIC attached to the OVN network from the previous step. 5. Run the VM. 6. Connect to the terminal on the VM and use: dhclient <name of extra vNIC> to request IP address from the OVN DHCP. Actual results: VM fails to get IP. Expected results: VM should get IP.
