Importing the appliance

Once the .ova file has been downloaded, it is ready to be imported into the host you have already prepared. Please ensure that the host meets the requirements stated earlier in this guide, then based on the hypervisor environment follow the instructions below.

VMware ESXi

The following steps can be used to import the virtual appliance into VMWare ESXi 6.5:

Open the vSphere web console on the host
Choose "Virtual Machines" from the Navigator
Select "Create/Register VM" option
A wizard will appear:
- Choose "Deploy a virtual machine from an OVF or OVA file" and click "Next"
- Enter a VM name e.g. "SM_Batch_01", and drag the downloaded .ova file onto the window and click "Next"
- Select a datastore that has enough capacity to store the virtual appliance and click "Next"
- From the "VM network" dropdown box, select a network
- Choose Thin or Thick disk provisioning (the Speechmatics Real-time Virtual Appliance supports either. Choose the options that is right for the hosting environment refer to VMWare documentation for help and click "Next"
- Check the details are correct and click "Finish"
The virtual appliance will import. This can take a few minutes depending on the datastore chosen.

Once the VM has imported it should be visible on the vSphere web console:

VMware Workstation Player

Open VMware Workstation Player
From the top options bar select "Player", then "File" and "Open..."
The "Open Virtual Machine" window will appear. Navigate to the ".ova" file you downloaded earlier, select it, click "Open"
Enter a VM name e.g. "SM_Batch_01"
A default storage location for the virtual appliance will be shown, the can be changed if required. Click "Import".
Dropdown box from the top options bar, click on "File"
The virtual appliance will import. This can take a few minutes depending on the hard disk chosen

Once the VM has imported it should be visible on the Workstation player:

VirtualBox

The following steps can be used to import the virtual appliance into VirtualBox 5.2 or above.

Open VirtualBox
From the Manager window select "File", then "Import Appliance..."
In the Name field, name the Real-time Virtual Appliance e.g. "SM_Batch_01"
Browse to the OVA file and click on the "Import" button

Once the VM has imported it should be visible on the VirtualBox Manager:

Amazon Web Services

This section explains how to create a Real-time Virtual Appliance EC2 instance on the Amazon Web Services (AWS) platform by using the AWS VM Import/Export tool. This tool is designed for importing VM images from the OVA file format provided by Speechmatics. You will import the image as an Amazon Machine Image (AMI), from which you can then launch machine instances.

The information in this section is taken from the official AWS documentation and parts of it have been extracted to focus more on the particulars of the Speechmatics Real-time Virtual Appliance. For more details of the Amazon VM image import process, please refer to https://docs.aws.amazon.com/vm-import/latest/userguide/vmimport-image-import.html

Prerequisites

There are a few pre-requisites that you will need to have setup before you can follow the instructions in this section:

AWS Command Line Interface (CLI)
Python 2.6.5 or higher

Please follow the recommendations on configuration of the AWS CLI by referring to the Getting Started guide.

Uploading the OVA file to S3

This section describes the process of uploading the Speechmatics OVA file to an Amazon S3 bucket from where it can be imported as an AMI instance. We recommend using a bucket in the same region where you want the AMI to be created and made available.

Once you've identified or created the S3 bucket on your account where the Speechmatics Real-time Virtual Appliance OVA will be uploaded to, you can use any of the tools below to help with the upload of the OVA file.

The following AWS SDK libraries support S3 multipart upload (which is the recommended method given the large size of the OVA file):
- AWS SDK for Java
- AWS SDK for .NET
- AWS SDK for PHP
- AWS SDK for Python (Boto)
- AWS SDK for Ruby
- You can also use the Multipart Upload API directly
User interface tools, for instance:
- S3 Browser
- CloudBerry S3 Explorer

For more information about the multipart uploads, see the AWS documentation.

Importing the OVA as AMI instance

After the Virtual Appliance OVA file has been successfully uploaded to an S3 bucket, it's time to import the image.

See the AWS documentation that covers uploading an image for full details.

The steps that you will perform in this section include (in orderr):

Creating a Service Role on your AWS account
Assigning a Role Policy to this Service Role
Importing the OVA for the Real-time Virtual Appliance from the S3 bucket file

Creating an Import Service Role

First of all, a service role needs to be created on your AWS account. This allows certain operations, including downloading images from an S3 bucket.

Create a file named trust-policy.json with the following policy:

{
   "Version": "2012-10-17",
   "Statement": [
      {
         "Effect": "Allow",
         "Principal": { "Service": "vmie.amazonaws.com" },
         "Action": "sts:AssumeRole",
         "Condition": {
            "StringEquals":{
               "sts:Externalid": "vmimport"
            }
         }
      }
   ]
}

Then use the create-role command from the AWS CLI to create a role named vmimport. You need to specify the full path of the trust-policy.json file:

aws iam create-role --role-name vmimport --assume-role-policy-document file://trust-policy.json

You need to ensure the that file:// prefix is prepended to the filename.

Creating a Role Policy

Create a file named role-policy.json with the following policy. Where you see ova-bucket it will need to be replaced with the name of the S3 bucket where the OVA file is stored.

{
   "Version":"2012-10-17",
   "Statement":[
      {
         "Effect":"Allow",
         "Action":[
            "s3:GetBucketLocation",
            "s3:GetObject",
            "s3:ListBucket" 
         ],
         "Resource":[
            "arn:aws:s3:::ova-bucket",
            "arn:aws:s3:::ova-bucket/*"
         ]  
      },
      {
         "Effect":"Allow",
         "Action":[
            "ec2:ModifySnapshotAttribute",
            "ec2:CopySnapshot",
            "ec2:RegisterImage",
            "ec2:Describe*"
         ],
         "Resource":"*"
      }
   ]
}

Use the put-role-policy command to attach the policy to the role. You must specify the full path to the location of the role-policy.json:

aws iam put-role-policy --role-name vmimport --policy-name vmimport --policy-document file://role-policy.json

Importing the OVA

Importing the virtual appliance image (OVA) to Amazon EC2 as an Amazon Machine Image (AMI) is the next step.

Create a file named containers.json with the following content. Where you see ova-bucket it will need to be replaced with the name of the S3 bucket where the OVA file is stored. The below example has a file named rtappliance-2.0.1-b21086.ova.

[
  {
    "Description": "Real Time Virtual Appliance OVA",
    "Format": "ova",
    "UserBucket": {
        "S3Bucket": "ova-bucket",
        "S3Key": "rtappliance-1.1.0-b21086.ova"
    }
}]

Use the import-image command to create an import task (Specify the full path to the location of the containers.json):

aws ec2 import-image --description "Real Time Virtual Appliance OVA" --disk-containers file://containers.json

The resulting JSON output will show an ImportTaskId which you can use to check the status of the import task. You do this by running the describe-import-image-tasks command:

aws ec2 describe-import-image-tasks --import-task-ids import-ami-abcd1234

You need to replace the task identifier with the ImportTaskId for your import task (import-ami-abcd1234 in this example).

When the status is in the completed state the AMI is ready to use.

Security

The following ports should be opened to be able to submit jobs and manage and monitor the Speechmatics Virtual Appliance. For more background on creating security groups refer to the official AWS documentation
