Hi Mike,

Actually Lloyd suggestion was rigth, the issue was from the iptables, I opened the 5240 port and it worked. The interesting question is, what is the default username and password for KVM PXE VM (Ubuntu 16.04)


Best,

 Wahi

        I can think of two things to check.

        First of all, got to Nodes -> Controllers and select your rack
        controller. Then select the Services tab and check that there
        is a green tick next to the “tftp” item. If there isn’t a
        green tick, then you will have to search the MAAS logs under
        /var/log/maas/ for possible problems.

        Secondly, there is always the possibility of a firewall
        blocking tftp traffic. This could be on your server or on your
        network.


In addition to Lloyd's suggestions, you can try using this script for testing:

https://git.launchpad.net/maas/tree/scripts/maas-test-enlistment

If you run this script manually from the same network as the nodes are booting from (using the private IP address, 10.0.17.1, as the parameter) you should be able to check that the TFTP files are accessible and the cloud parameters are correct (that is, the MAAS metadata server that cloud-init will contact is reachable and providing correct metadata URLs for booting nodes).

Regards,
Mike
