Description of problem: During deployment overcloud is not able to get the ipxe image. Version-Release number of selected component (if applicable): RHEL OSP 8 Overcloud controller/compute nodes are VM in RHEV environment. How reproducible: Everytime for Cu. Steps to Reproduce: 1. Try the deployment of overcloud using standard "openstack overcloud deploy" command. 2. Overcloud node is able to get the DHCP ip address from undercloud but not showing ipxe image. 3. Actual results: It's not getting boot. Expected results: It should be able to boot successfully. Additional info: If we are having physical compute node then it's able to get the image. Issue is only coming with RHEV controller nodes.

Can you check if this is a MTU issue? as you are testing teleon virt, you may need to lower the MTU of your tenant networks in order for the data and tunneling overhead to fit into a standard 1500 packet. Retry the deployment after running these commands $ sudo ip link set dev eth1 mtu 1400 $ echo -e "\ndhcp-option-force=26,1400" | sudo tee -a /etc/dnsmasq-ironic.conf $ sudo systemctl restart 'neutron-*'
