Joyent’s SmartOS, a fairly recent hypervisor for virtualization, provides a number of prebuilt virtual machine images for various operating systems but doesn’t yet have one available for Ubuntu 12.04 LTS. \u00a0This post provides the steps required to install it manually including the basic SmartOS commands as well as some Ubuntu-specific customizations.<\/p>\n

    \n
  1. Create a JSON file with the virtual machine parameters. \u00a0Also see the SmartOS Wiki<\/a> for some additional options and details.\n
    {\r\n  \"alias\": \"ubuntu12\",\r\n  \"hostname\": \"ubuntu12\",\r\n  \"brand\": \"kvm\",\r\n  \"vcpus\": 1,\r\n  \"autoboot\": false,\r\n  \"ram\": 4096,\r\n  \"resolvers\": [ \"10.1.1.1\" ],\r\n  \"disks\": [\r\n    {\r\n      \"boot\": true,\r\n      \"model\": \"virtio\",\r\n      \"size\": 40960\r\n    }\r\n  ],\r\n  \"nics\": [\r\n    {\r\n      \"nic_tag\": \"admin\",\r\n      \"model\": \"virtio\",\r\n      \"ip\": \"10.1.1.11\",\r\n      \"netmask\": \"255.255.255.0\",\r\n      \"gateway\": \"10.1.1.1\",\r\n      \"primary\": true\r\n    }\r\n  ]\r\n}<\/pre>\n<\/li>\n
  2. Create the virtual machine with the vmadm<\/code> command using the JSON file as the input.\n
    # vmadm create -f ubuntu-12.04.json\r\nSuccessfully created 3b202a79-f148-4c87-bb7f-ff9d64f724ca<\/pre>\n<\/li>\n
  3. Copy the Ubuntu 12.04 LTS install ISO to the root dataset for this virtual machine.  This assumes the ISO has already been copied to the \/zones\/isos<\/code> directory on the SmartOS server.\n
    # cp \/zones\/isos\/ubuntu-12.04-server-amd64.iso \\\r\n     \/zones\/3b202a79-f148-4c87-bb7f-ff9d64f724ca\/root\/.<\/pre>\n<\/li>\n
  4. Boot the VM to the ISO.\n
    # vmadm start 3b202a79-f148-4c87-bb7f-ff9d64f724ca \\\r\n              order=cd,once=d cdrom=\/ubuntu-12.04-server-amd64.iso,ide\r\nSuccessfully started 3b202a79-f148-4c87-bb7f-ff9d64f724ca<\/pre>\n<\/li>\n
  5. Get the VNC IP and port from the VM.\n
    # vmadm info 3b202a79-f148-4c87-bb7f-ff9d64f724ca vnc\r\n{\r\n  \"vnc\": {\r\n    \"host\": \"10.1.1.4\",\r\n    \"port\": 63407,\r\n    \"display\": 57507\r\n  }\r\n}<\/pre>\n<\/li>\n
  6. Connect to the VM with VNC and complete the installation as normal, including the reboot at the end.<\/li>\n
  7. Enable the serial console in Ubuntu with the steps from the Ubuntu SerialConsoleHowto<\/a>. \u00a0This step is optional but adds some nice administration benefits as demonstrated in the next step.\n
      \n
    1. Paste the following into \/etc\/init\/ttyS0.conf<\/code>.\n
      # ttyS0 - getty\r\n#\r\n# This service maintains a getty on ttyS0 from the point the system is\r\n# started until it is shut down again.\r\n\r\nstart on stopped rc or RUNLEVEL=[2345]\r\nstop on runlevel [!2345]\r\n\r\nrespawn\r\nexec \/sbin\/getty -L 115200 ttyS0 vt102<\/pre>\n<\/li>\n
    2. Ask upstart to start the getty.\n
      $ sudo start ttyS0<\/pre>\n<\/li>\n<\/ol>\n<\/li>\n
    3. The serial console can then be connected to from the SmartOS host with the vmadm<\/code> tool.  Exiting from this console is done with CTRL-]<\/code>.\n
