Set Up Your VMware Virtual Machine for a Single On-premises Server

Follow these steps to setup and configure your VM on a single server in an on-premises deployment:

Verify that your system meets the VM requirements.

Resource	Minimum Requirements
Processor	Eight (8) virtual CPUs
Memory	64 GB RAM
Local disk storage	256 GB SSD with minimum disk IOPS of 1000 for a standard 4kb block size (Note: This must be an SSD; use of other storage options can lead to system instability and are not supported.)
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 on-premises server:

Port or Protocol Number	Protocol	Component Access
4	IP Protocol	Calico networking (IP-in-IP Protocol)
22	TCP	SSH
80	TCP	Nginx
179	TCP	Calico networking (BGP)
443	TCP	NetQ UI
2379	TCP	etcd datastore
4789	UDP	Calico networking (VxLAN)
5000	TCP	Docker registry
6443	TCP	kube-apiserver
30001	TCP	DPU communication
31980	TCP	NetQ Agent communication
31982	TCP	NetQ Agent SSL communication
32708	TCP	API Gateway

Download the NetQ Platform image.
1. 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, user1@domain.com.mlnx.
2. Open the Downloads menu.
3. Click Software.
4. Open the Cumulus Software option.
5. Click All downloads next to Cumulus NetQ.
6. Select 4.0.0 from the NetQ Version dropdown.
7. Select VMware from the Hypervisor dropdown.
8. Click Show Download.
9. 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.
VMware Example Configuration
This example shows the VM setup process using an OVA file with VMware ESXi.
1. Enter the address of the hardware in your browser.
2. Log in to VMware using credentials with root access.
3. Click Storage in the Navigator to verify you have an SSD installed.
4. Click Create/Register VM at the top of the right pane.
5. Select Deploy a virtual machine from an OVF or OVA file, and click Next.
6. 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.
7. Drag and drop the NetQ Platform image file you downloaded in Step 1 above.
8. Click Next.
9. Select the storage type and data store for the image to use, then click Next. In this example, only one is available.
10. Accept the default deployment options or modify them according to your network needs. Click Next when you are finished.
11. 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.
12. Once completed, view the full details of the VM and hardware.

cumulus@ubuntu:~$

Verify the platform is ready for installation. Fix any errors indicated before installing the NetQ software.
```
cumulus@hostname:~$ sudo opta-check
```
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
```
Add the same NEW_HOSTNAME value to /etc/hosts on your VM for the localhost entry. Example:
```
127.0.0.1 localhost 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.
```
cumulus@:~$ netq bootstrap master interface eth0 tarball /mnt/installables/netq-bootstrap-4.0.0.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 [purge-db|keep-db] and then try again.
If you have changed the IP address or hostname of the NetQ On-premises VM after this step, you need to re-register this address with NetQ as follows:

Reset the VM, indicating whether you want to purge any NetQ DB data or keep it.
```
cumulus@hostname:~$ netq bootstrap reset [purge-db|keep-db]
```
Re-run the Bootstrap CLI. This example uses interface eth0. Replace this with your updated IP address, hostname or interface using the interface or ip-addr option.
```
cumulus@:~$ netq bootstrap master interface eth0 tarball /mnt/installables/netq-bootstrap-4.0.0.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.

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 CLI with the pod-ip-range option. For example:
```
cumulus@hostname:~$ netq bootstrap master interface eth0 tarball /mnt/installables/netq-bootstrap-4.0.0.tgz pod-ip-range 10.255.0.0/16
```
Docker Default Bridge Interface
The default Docker bridge interface is disabled in NetQ. If you need to reenable 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:

Use the Admin UI (recommended)
Use the CLI
