Setting Up Hyper-V VMR Machine Images
This tutorial will walk you through the steps required to get a single Solace Virtual Message Router (VMR) machine image instance running in a Microsoft Hyper-V environment and ready for messaging.
- Step 1: Get a VMR
- Step 2: Create a New Virtual Machine
- Step 3: Configure the VMR’s Host Name
- Step 4: Access the Solace CLI
- Step 5: Review the VMR Configuration Defaults
- Additional VMR Machine Image Configuration
- You have access to Windows Server 2012.
For Evaluation and Enterprise VMR editions, the system resources that you provision for the VM automatically determines the number of client connections to the VMR that can be made. If you provision:
- 30 GB of disk space, 4 GB of RAM, and two vCPUs—a maximum of 1,000 client connections are possible. This is the minimum required system resources.
- 30 GB of disk space, 12 GB of RAM, and four vCPUs or greater—a maximum of 10,000 client connections are possible.
For Community VMR editions, a maximum of 100 client connections is permitted. Increasing the system requirements will not increase the number of available client connections.
Note: To deploy VMRs in high-availability (HA) redundancy groups, you must set up three separate VMR instances as discussed in this tutorial, and then configure them appropriately as a group. For more information on how to configure existing VMRs as an HA group, see Managing VMR Redundancy.
The first requirement is to obtain a VMR. The VMR is distributed as a Virtual Hard Disk (.vhd) file, which allows it to be easily imported in to virtualization software.
- Evaluation or Community edition of the VMR—Go to dev.solace.com/downloads/, then in the Products section, click Virtual Message Router, then click Hyper-V.
After you accept the license agreement, a VHD called
soltr-<version>-vmr-<type>.vhd.gzwill be downloaded.
- Enterprise version of the VMR—If you have purchased an Enterprise version of the VMR, Solace will provide information for how to download an enterprise version of the VMR VHD file package from a secure Solace server. Contact Solace Support at firstname.lastname@example.org if you require assistance.
To create a new VM image for the VMR, you must create a new virtual machine from the VHD file.
To a new VM image for the VMR and start it , do the following:
- Open the Hyper-V Manager, and then right-click the Windows Server instance that will host the new VM and select New -> Virtual Machine.
This will launch the New Virtual Machine Wizard.
- In the “Before You Begin” step of the wizard click Next.
Note: The .vhd image downloaded in a previous step is compressed using gz compression and will need to be decompressed and placed in a suitable location; the default is “Documents > Hyper-V > Virtual hard drives”.
- Name the VMR instance, and click Next.
Assign memory for the VMR instance, and click Next.
- Select a network adapter connected to a virtual switch, and click Next.
Note: An external virtual switch must be created prior the creating the new virtual machine if the VMR instance is to be reachable from external hosts.
- Select the virtual hard disk that the VMR will use, and click Next when complete.
- Review the settings, then click Finish.
Wait until the Wizard closes. The VMR image will display in the Hyper-V Manager.
- Power on the VMR.
In the Hyper-V Manager, right-click the VMR instance you want to start, then click Start.
- Open the console.
Right-click the VMR, then click Connect.
The Solace VMR is successfully started when the login prompt similar to the following appears.
- Login to the VMR.
The VMR messaging application software resides in a container that is wrapped within a Linux OS to form a VMR virtual machine image. In its default state, this VMR Linux host environment has remote login disabled and contains no passwords.
To log in to the VMR for the first time you must log in as
sysadmin, which is the default user account for the Linux host environment. You will be prompted to create a password for that user.
When you are logged in as
sysadmin, you can then create passwords for the default users through the console. You must assign these default users passwords to allow remote login.
To set the hostname for the new VMR, enter the following:
[sysadmin@solace ~]$ solacectl hostname configure <hostname>
<name> is the hostname of the VMR. A hostname may contain up to 50 characters, composed of alphanumeric characters 0 to 9, a to z, A to Z, and hyphens (although hyphens cannot be used at the beginning or end of a hostname).
You can access the Solace CLI from the console in the Linux host environment. This is done through the Solace Control Utility.
When you first access the Solace CLI, you should do the following:
- set a password for the admin user, which has access to all CLI commands
- determine the VMR’s IP address so that you can enable remote access
- To enter the Solace CLI from the console in the Linux host environment, enter the following command in the Linux host shell.
[sysadmin@solace ~]$ solacectl cli
A CLI banner and prompt appears.
>prompt, you are at the User EXEC level of the Solace CLI command structure.
- Within the Solace CLI, enter the following commands to set the password for the admin user:
solace(configure)# username admin
solace(configure/username)# change-password <password>
- To determine the IP address assigned to the VMR, enter the following command:
solace> show ip vrf management
The displayed output lists the IP address assigned to the VMR (listed for
eth0:1), which can be used to remotely manage the VMR (that is, not from the VM console).
- To remotely access the Solace CLI for the VMR, you can now ssh to port 22 of the VMR’s IP address and login in as the
Tip: In addition to the admin CLI User, you can create additional CLI and file transfer users through the Solace CLI in the manner described in Managing Management User Authentication/Authorization.
Unlike a Solace appliance, by default, a VMR starts with a basic configuration that has most common services enabled and ready for use. This basic configuration and the default ports that are used can be modified as required. For details, see VMR Configuration Defaults.
You now have a VMR machine image with a basic configuration that is ready for messaging tasks. However, there are additional configuration tasks that you can perform. At this stage, you should do the following:
- Review the extra configuration tasks specific to VMR machine images presented on the Additional VMR Machine Image Configuration page.
These additional configurations allow you to further customize your VMR machine image to better suit your particular use-case and to make it more suitable for a production deployment.
- Begin to configure and manage the VMR machine image’s messaging operations through the Solace CLI in the same manner as you would other Solace messaging routers (say, a Solace messaging appliance or a Solace VMR Docker container). For information on how to perform these configuration and management tasks, see the topics in the Router Configuration category of the Solace customer documentation.
