I'm still not quite sure why your MAAS provisioning doesn't have the prompt without a default route if your bare metal only has one NIC.  Your bare metal install must somehow have found a default route in the network settings, I guess.

I used a dedicated node mainly is because I didn't know it would be possible to use the MAAS/juju node as the zookeeper node.  From this MAAS wiki page - https://wiki.ubuntu.com/ServerTeam/MAAS/Juju, it requests to have at least two nodes added to MAAS to start to use juju.  To my understanding, one node is for Zookeeper node, another is for any possible juju service node.  The Zookeeper node was automatically provisioned by MAAS (well, except the manual answer to the network configuration screen due to the absence of a default route, and also, the manual answer to the name server, which is the IP address of the MAAS/juju node).  Can you share with me how you managed to have maas/juju/zookeeper loaded in one node?

Best,
Dafang

Ok, I see.
I also have one issue with the preseed file in my bare metal setup.

May  2 14:41:00 ubuntu partman:   No matching physical volumes found

>May  2 14:41:00 ubuntu partman-lvm:   No volume groups found

During the installation I have to manually choose a disk to install the system...

My bare metal setup is mainly the same as the virtual setup except that I only use one NIC for the MAAS node.
But the weirdest think is that I have the exact same trace in the node of my virtual setup. And I'm not ask for choose a disk in the virtual setup...

One more thing why do you use a dedicated node for zookeeper?

Cheers!

Hi, Sebastien,

>Thanks for looking into this.  You are correct that I only enabled the Host-Only interface in VirtualBox, but I did user maas-dhcp package to enable the MAAS node to manage DNS and DHCP.  In a real-world scenario, all the service nodes would sit behind the maas/juju node, so that they will only have one NIC (or a team) to communicate with the MAAS node only, and use the MAAS node's squid as the proxy to communicate with the rest of the world.  I could have the service node VM's to have two NIC's, but I intended to set it up this way to mimic a scenario that would secure the service nodes (in your term, MAASlave nodes).
