Set Up Your VMware Virtual Machine for a Single Remote Server
Follow these steps to setup and configure your VM for a remote deployment:
Verify that your system meets the VM requirements.When using a VM, the following system resources must be allocated:
Resource Minimum Requirement Processor Four (4) virtual CPUs Memory 8 GB RAM Local disk storage For NetQ 3.2.x and later: 64 GB (2 TB max)
For NetQ 3.1 and earlier: 32 GB (2 TB max)
Network interface speed 1 Gb NIC Hypervisor VMware ESXi™ 6.5 or later (OVA image) for servers running Cumulus Linux, CentOS, Ubuntu and RedHat operating systems
Confirm that the needed ports are open for communications.You must open the following ports on your NetQ Platform:
Port Protocol Component Access 8443 TCP Admin UI 443 TCP NetQ UI 31980 TCP NetQ Agent communication 32708 TCP API Gateway 22 TCP SSH
Port 32666 is no longer used for the NetQ UI.
Download the NetQ Platform image.
Access to the software downloads depends on whether you were an existing customer before September 1, 2020 or whether you are a new customer. Please follow the instructions accordingly.Existing customer who has downloaded Cumulus Networks software before September 1, 2020:
- On the MyMellanox Downloads page, select NetQ from the Software -> Cumulus Software list.
- Click 3.3 from the Version list, and then select 3.3.1 from the submenu.
- Select VMware (Cloud) from the HyperVisor/Platform list.
- Scroll down to view the image, and click Download. This downloads the NetQ-3.3.1-opta.tgz installation package.
- On the My Mellanox support page, log in to your account. If needed create a new account and then log in.
Your username is based on your Email address. For example, firstname.lastname@example.org.
- Open the Downloads menu.
- Click Software.
- Open the Cumulus Software option.
- Click All downloads next to Cumulus NetQ.
- Select 3.3.1 from the NetQ Version dropdown.
- Select VMware (cloud) from the Hypervisor dropdown.
- Click Show Download.
- Verify this is the correct image, then click Download.
The Documentation option lets you download a copy of the user manual. Ignore the Firmware and More files options as these do not apply to NetQ.
Setup and configure your VM.
Open your hypervisor and set up your VM. You can use this example for reference or use your own hypervisor instructions.
VMware Example ConfigurationThis example shows the VM setup process using an OVA file with VMware ESXi.
Enter the address of the hardware in your browser.
Log in to VMware using credentials with root access.
Click Storage in the Navigator to verify you have an SSD installed.
Click Create/Register VM at the top of the right pane.
Select Deploy a virtual machine from an OVF or OVA file, and click Next.
Provide a name for the VM, for example NetQ.
Tip: Make note of the name used during install as this is needed in a later step.
Drag and drop the NetQ Platform image file you downloaded in Step 2 above.
Select the storage type and data store for the image to use, then click Next. In this example, only one is available.
Accept the default deployment options or modify them according to your network needs. Click Next when you are finished.
Review the configuration summary. Click Back to change any of the settings, or click Finish to continue with the creation of the VM.
The progress of the request is shown in the Recent Tasks window at the bottom of the application. This may take some time, so continue with your other work until the upload finishes.
Once completed, view the full details of the VM and hardware.
Log in to the VM and change the password.
Use the default credentials to log in the first time:
- Username: cumulus
- Password: cumulus

Verify the platform is ready for installation. Fix any errors indicated before installing the NetQ software.
cumulus@hostname:~$ sudo opta-check-cloud
Change the hostname for the VM from the default value.
The default hostname for the NetQ Virtual Machines is ubuntu. Change the hostname to fit your naming conventions while meeting Internet and Kubernetes naming standards.
Kubernetes requires that hostnames are composed of a sequence of labels concatenated with dots. For example, “en.wikipedia.org” is a hostname. Each label must be from 1 to 63 characters long. The entire hostname, including the delimiting dots, has a maximum of 253 ASCII characters.
The Internet standards (RFCs) for protocols specify that labels may contain only the ASCII letters a through z (in lower case), the digits 0 through 9, and the hyphen-minus character ('-').
Use the following command:
cumulus@hostname:~$ sudo hostnamectl set-hostname NEW_HOSTNAME
Run the Bootstrap CLI. Be sure to replace the eth0 interface used in this example with the interface on the server used to listen for NetQ Agents.
:~$ netq bootstrap master interface eth0 tarball /mnt/installables/netq-bootstrap-3.3.1.tgz
Allow about five to ten minutes for this to complete, and only then continue to the next step.
If this step fails for any reason, you can run
netq bootstrap reset and then try again.
If you have changed the IP address or hostname of the NetQ Cloud VM after this step, you need to re-register this address with NetQ as follows:
Reset the VM.
cumulus@hostname:~$ netq bootstrap reset
Re-run the Bootstrap CLI. This example uses interface eth0. Replace this with your updated IP address, hostname or interface using the
:~$ netq bootstrap master interface eth0 tarball /mnt/installables/netq-bootstrap-3.3.0.tgz
Consider the following for container environments, and make adjustments as needed.Flannel Virtual Networks
If you are using Flannel with a container environment on your network, you may need to change its default IP address ranges if they conflict with other addresses on your network. This can only be done one time during the first installation. You do this by running the
The address range is 10.244.0.0/16. NetQ overrides the original Flannel default, which is 10.1.0.0/16.
To change the default address range, use the bootstrap CLI with the
pod-ip-range option. For example:
cumulus@hostname:~$ netq bootstrap master interface eth0 tarball /mnt/installables/netq-bootstrap-3.3.1.tgz pod-ip-range 10.255.0.0/16Docker Default Bridge Interface
The default Docker bridge interface is disabled in NetQ. If you need to re-enable the interface, contact support.
The final step is to install and activate the NetQ software. You can do this using the Admin UI or the CLI.
Click the installation and activation method you want to use to complete installation:
