v. 43.0.1125


1 Exporting the Virtual Machine Image


1.1 Stopping the Virtual Machine

Steps

  1. Go to System/VM.
  2. In the Virtual Machine Configuration table, click located on the same row as the VM you wish to stop.

Result

The virtual machine stops. In the Virtual Machine Status table, Stopped will be displayed under the State column.

Next Step

1.2 Taking a Record of the Virtual Machine

1.2 Taking a Record of the Virtual Machine

Steps

  1. Go to System /VM.
  2. Take a screen shot of the Virtual Machines page.
  3. Save the screen shot.
  4. Go to Network/Interfaces
  5. Take a screen shot of the Ethernet Link Configuration table.
  6. Save the screen shot.

Result

You will need the information on RAM size, VM name, storage size, USB, number of CPU, and Ethernet link during the Importing a Virtual Machine Image to the Unit File Management System and Configuring a Link as a Virtual Switch steps when importing the Virtual Machine image into a new unit. Furthermore, if anything goes wrong, you will have the configuration details to fall back to.

1.3 Taking a Backup of the Virtual Machine Image

1.3 Taking a Backup of the Virtual Machine Image

Steps

  1. Go to Management/File.
  2. In the Internal files table, click the file link located next to Disk Image of the Virtual Machine.

Result

The image file of the VM will be downloaded to your server.

2 Importing a Virtual Machine Image to a Unit


2.1 Information to know before Importing the Virtual Machine Image

  • Make sure you have a VM License on the new unit.
  • Make sure the new unit has enough RAM and storage capacity to accommodate the Virtual Machine. Refer to the screen shots taken earlier. This information will be required at the Adding a Virtual Machine step.
  • Refer to the screen shots taken earlier to know which links are enabled as Virtual Switches. This information will be required at the Configuring a Link as a Virtual Switch step.

2.2 Adding a Virtual Machine

Before You Start

The VirtualSwitch parameter must be configured to enable the link you wish to use to contact the virtual machine. Refer to Configuring a Link as a Virtual Switch .

You must have a virtual machine licence and the VM service must be started.

Caution

It is a best practice to create the Virtual Machine in a test environment. If not enough memory is allocated and swap is disabled, the Virtual Machine will stop, and the installation will need to be restarted from the beginning.

Context

If you are not familiar with the meaning of the fields and buttons, click Show Help, located at the upper right corner of the Web page. When activated, the fields and buttons that offer online help will change to green and if you hover over them, the description will be displayed.

Steps

  1. Go to System/VM.
  2. In the Virtual Machine Creation table, complete the Vm Name field.

    Note

    Vm names must be unique.

  3. In the Ram(Mb) field, enter the amount of RAM required to run the virtual machine.

    Caution

    To reduce the wear-and-tear of the Solid State Drive, make sure to allocate the maximum amount of RAM possible to the virtual machine.

    Note

    For instance, 87.5% of the actual available RAM, or 1.5 Gb for units with 2 Gb of RAM, 3.5 Gb with 4 Gb of RAM and for 7 Gb with 8 Gb of RAM.

  4. Complete the Storage(Gb) field.

    Note

    10 Gb is the maximum value one can allocate in a typical Sentinel equipped with a 16 Gb Solid State Drive.

  5. From the Image Format selection list, choose the format of the image.

    Note

    • Use QCOW2 for space efficiency and flexibility.
    • Use RAW for improved performance

  6. From the Nb Cores selection list, select the number of cores the virtual machine will be using.

    Important

    It is not possible to modify the settings (RAM, name, etc.) once the virtual machine has been created. The only way to change the settings, is to delete the virtual machine and to create it once again.

  7. Click .

    Note

    A maximum of 2 virtual machines can be added.

Result

The virtual machine will be displayed in both the Virtual Machine Configuration and the Virtual Machine Status tables.

  3. In the Import File Through Web Browser table, from the Path selection list, select vm/images/.
  4. Browse to the location of the file containing the virtual machine image to install on the unit.
  5. Click Import.

    Note

    A factory reset will not remove the vm files from the Internal filestable.

Result

The imported image file will appear in the Internal files table, under Management/File.

2.5 Setting the Virtual Machine to Automatic Start

Before You Start

If you are not familiar with the meaning of the fields and buttons, click Show Help, located at the upper right corner of the Web page. When activated, the fields and buttons that offer online help will change to green and if you hover over them, the description will be displayed.

Context

If the virtual machine you wish to start requires resources equivalent to the available resources on the unit, then it will not be possible to start another virtual machine. It is only possible to start a virtual if there are enough resources on the unit.

Steps

  1. Go to System/VM.
  2. In the Virtual Machine Configuration table, from the Startup dropdown list, select Auto.
  3. Click Apply.

Result

When the Vm Service is started, the virtual machine will also be started.
