Writing the ISO Image to a USB Disk

The ISO image can be copied to a USB disk (flash drive) and used as a bootable media on the Intel NUC. The following sections describe the process of creating the bootable USB disk on Mac OS X and Windows.

Mac OS X / Linux Instructions

  1. 1.
    Insert a USB disk that is at least 1GB in size, into a USB port on the Mac. The disk’s content will be overwritten.
  2. 2.
    Open a terminal window.
  3. 3.
    Type diskutil list (OS X) or fdisk -l (Linux) and identify the physical disk you’re interested in imaging. It should be /dev/diskN (OS X) or /dev/sdN (Linux). In the example below, I have a 1GB USB disk in my Mac's USB port:
    dave@schadenfreude ~/Downloads> diskutil list
    /dev/disk0 (internal, physical):
    #: TYPE NAME SIZE IDENTIFIER
    0: GUID_partition_scheme *500.3 GB disk0
    1: EFI EFI 209.7 MB disk0s1
    2: Apple_CoreStorage Macintosh HD 499.4 GB disk0s2
    3: Apple_Boot Recovery HD 650.0 MB disk0s3
    /dev/disk1 (internal, virtual):
    #: TYPE NAME SIZE IDENTIFIER
    0: Apple_HFS Macintosh HD +499.1 GB disk1
    Logical Volume on disk0s2
    DCA39E1F-1CB4-4386-8E67-0AD63B4A069D
    Unencrypted
    /dev/disk2 (external, physical):
    #: TYPE NAME SIZE IDENTIFIER
    0: FDisk_partition_scheme *1.0 GB disk2
    1: Windows_FAT_32 UBUNTU-SERV 1.0 GB disk2s1
  4. 4.
    Run diskutil unmountDisk /dev/diskN (OS X) or umount /dev/sdN (Linux) to unmount the device (replace N with the actual disk number from the output above):
    dave@schadenfreude ~/Downloads> diskutil unmountDisk /dev/disk2
    Unmount of all volumes on disk2 was successful
  5. 5.
    Next, write the image to disk. Run sudo dd if=<path_to_downloaded_iso> of=/dev/diskN, wait until it completes:
    dave@schadenfreude ~/Downloads> sudo dd if=thousandeyes-pa-1.9.100.iso of=/dev/disk2
    1175552+0 records in
    1175552+0 records out
    601882624 bytes transferred in 267.718384 secs (2248193 bytes/sec)

Windows Instructions

The following instructions are based on Rufus, an open-source application for creating bootable USB flash drives.
  1. 1.
    A copy of Rufus can be obtained from here.
  2. 2.
    Start Rufus.
  3. 3.
    Connect a USB drive that is at least 1GB in size. The disk’s content will be overwritten. If there is only one USB drive on the Windows system, Rufus automatically selects it and it will be displayed under Device. Otherwise, use the down-arrow to select the desired USB drive.
  1. 4.
    Click SELECT and browse to select the downloaded ISO image. In the above screen shot, the filename of the selected image is "thousandeyes-pa-0.162.iso."
  2. 5.
    The screenshot above shows the default settings; they can be left as is. Note that the Cluster size default will vary depending on the size of the USB drive. Leave it to the selected default size.
  3. 6.
    Click START.
  1. 7.
    On the next screen, select Write DD Image mode and click OK. DD Image Mode is the recommended format.
  1. 8.
    Click OK to start the boot disk creation.
  2. 9.
    When the process completes, remove the USB drive.

If USB is not shown as an option, power off the NUC, unplug the USB drive, plug it back in and power up the NUC.
Note: The BIOS will recognize the USB drive as a bootable device even if the USB flash drive is blank (nothing in it). If the BIOS does not recognize the USB drive as a valid bootable device, when there is a USB flash drive inserted, check that the BIOS version is current. If not current upgrade to the latest version.
  1. 6.
    On booting from the USB drive, the installation process will start automatically. No user intervention is required, The initial phase will progress fairly quickly, a progress bar will narrate the progress. The final phase is shown by the "Finishing the installation" screen, "Running preseed," the progress bar will show "14%." The installation process are downloading the required software packages. This screen may remain in this state for about 15 minutes, depending on the speed of the network interface and the delays to the download server. Do not power off the NUC. Leave it until it automatically powers off.
  2. 7.
    On completing the installation, the NUC will automatically power off.

Troubleshooting

USB Drive Not Recognized as a Bootable Device

A USB drive is plugged in, tapping F10 at power-up, on the "Boot" BIOS screen, USB drive is not recognized as a bootable device.
Resolution: Disable UEFI boot support. Check that the BIOS version is current. If not current, upgrade to the latest version.

Malformed IP Address

Ubuntu installation fails with a "blue screen" showing "Malformed IP Address."
Resolution: Verify that the Ethernet connection to the NUC has a link signal. Verify that the Link LED on the RJ-45 port is lit. Verify that there is a DHCP server on the network (broadcast domain) that the NUC is connected to.

No Root File System Defined

Ubuntu installation fails with "No Root File System Defined" message. This situation can occur if USB devices are attached to the NUC via a USB hub.
Resolution: Do not use USB hub to connect keyboard and USB flash drive to the NUC.

"thousandeyes-va login:" Prompt Is Shown on the Screen

The expected blue "ThousandEyes Virtual Appliance" management screen is not displayed. Instead, a black screen with "thousandeyes-va login:" prompt is shown.
This is a symptom of an unsuccessful installation. The agent is missing the te-pa package which, in addition to the web admin interface, provides the physical console functionality.
Resolution: Components of the Virtual Agent are missing. Most likely caused by the lack of non-proxied and unrestricted access to the internet during the appliance installation. Reinstall the appliance in an environment that satisfies the requirements listed in the installation environment requirements.

Keyboard Not Working

When the installation completes, keypresses are not recognized.
Resolution: Most likely incomplete installation. Reinstall the appliance in an environment that satisfies the requirements listed in the installation environment requirements.
