Ubuntu 16.04 : install MAAS within Ubuntu 16.04 LXD and manage virtual machines running in KVM with MAAS

Here are logs when setting up MAAS within LXD container and managing virtual machines running in KVM with MAAS.

Here is my environment.

I have single box.

LXD(maas)             nodes ( virtual machine within KVM)

---------------------------------------------------------------------------

Ubuntu host 16.04

Create an LXD profile for maas

hattori@ubuntu:~$ lxc profile copy default maas

Edit the LXD profile.

hattori@ubuntu:~$ lxc profile show maas name: maas config:  raw.lxc: |-    lxc.cgroup.devices.allow = c 10:237 rwm    lxc.aa_profile = unconfined    lxc.cgroup.devices.allow = b 7:* rwm  security.privileged: "true" description: "" devices:  eth0:    name: eth0    nictype: bridged    parent: virbr4    type: nic  eth1:    name: eth1    nictype: bridged    parent: virbr3    type: nic

Edit the profile

hattori@ubuntu:~$ for i in `seq 0 7`; do lxc profile device add maas loop$i unix-block path=/dev/loop$i; done

hattori@ubuntu:~$ lxc profile show maas name: maas config:  raw.lxc: |-    lxc.cgroup.devices.allow = c 10:237 rwm    lxc.aa_profile = unconfined    lxc.cgroup.devices.allow = b 7:* rwm  security.privileged: "true" description: "" devices:  eth0:    name: eth0    nictype: bridged    parent: virbr4    type: nic  eth1:    name: eth1    nictype: bridged    parent: virbr3    type: nic  loop0:    path: /dev/loop0    type: unix-block  loop1:    path: /dev/loop1    type: unix-block  loop2:    path: /dev/loop2    type: unix-block  loop3:    path: /dev/loop3    type: unix-block  loop4:    path: /dev/loop4    type: unix-block  loop5:    path: /dev/loop5    type: unix-block  loop6:    path: /dev/loop6    type: unix-block  loop7:    path: /dev/loop7    type: unix-block hattori@ubuntu:~$

Launch an instance

hattori@ubuntu:~$ lxc launch -p maas ubuntu-xenial xenial-maas hattori@ubuntu:~$ lxc exec xenial-maas bash

Install maas

root@xenial-maas:~# apt-cache search maas root@xenial-maas:~# apt-add-repository -y ppa:maas/stable root@xenial-maas:~# apt-get update root@xenial-maas:~# apt install maas

Set up MAAS to access to GUI

root@xenial-maas:~# maas createadmin --username=admin Password: Again: Email: a@a.com root@xenial-maas:~#

Access to the GUI

http:// <maas ip>:5240/MAAS

--

To run maas-dhcpd, we need to configure dhcp configuration manually.

https://maas.ubuntu.com/docs2.0/maascli.html#

On the mass container.

root@xenial-maas:~# systemctl list-unit-files --type=service | grep maas-dhcp maas-dhcpd.service                         enabled maas-dhcpd6.service                        enabled

Maas-dhcpd is not running at the moment.

root@xenial-maas:~# systemctl status maas-dhcpd ● maas-dhcpd.service - MAAS instance of ISC DHCP server for IPv4   Loaded: loaded (/lib/systemd/system/maas-dhcpd.service; enabled; vendor prese   Active: inactive (dead) Condition: start condition failed at Wed 2016-10-26 15:39:39 UTC; 25min ago           ConditionPathExists=/var/lib/maas/dhcpd-interfaces was not met     Docs: man:dhcpd(8) root@xenial-maas:~#

Obtain a key.

root@xenial-maas:~# maas-region apikey --username=admin EaxXNt2NZFvx34wTEF:VcBrSCxhMHsefzNUMN:URtfHuGWtbPLcXQzzCkH3sZeUZxTAdkv

Login

root@xenial-maas:~# maas login my-maas http://127.0.0.1/MAAS/api/2.0 EaxXNt2NZFvx34wTEF:VcBrSCxhMHsefzNUMN:URtfHuGWtbPLcXQzzCkH3sZeUZxTAdkv You are now logged in to the MAAS server at http://127.0.0.1/MAAS/api/2.0/ with the profile name 'my-maas'. For help with the available commands, try:  maas my-maas --help root@xenial-maas:~#

2. Enable DHCP and DNS.

I performed that via MAAS GUI.

3. registre nodes.

I will manage virtual machine nodes with maas.

Create a virtual machine disk.

You need to specify preallocation=metadata so that MAAS can recognize a storage size of a VM.

# qemu-img create -o preallocation=metadata -f qcow2 m-node01.qcow2 5g

Create a virtual machine via virt-manager.

.

Add the disk you created with “qemu-img create”

Change boot order

1st : PXE boot

2nd : HDD

Start the VM and then stop the VM forcely.

Register the node via Maas GUI.

Check the MAC address of the VM

root@ubuntu:~# virsh dumpxml m-node02 | grep -i 'mac address'      <mac address='52:54:00:c4:6a:7f'/> root@ubuntu:~#

Install ubuntu 16.04 on that virtual machine.

I have registered two nodes.
