Set Up Your KVM Virtual Machine for a Single Remote Server

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

1. 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	KVM/QCOW (QEMU Copy on Write) image for servers running CentOS, Ubuntu and RedHat operating systems

2. Confirm that the needed ports are open for communications.

   You must open the following ports on your NetQ Platform:

   Port or Protocol Number	Protocol	Component Access
   8443	TCP	Admin UI
   443	TCP	NetQ UI
   31980	TCP	NetQ Agent communication
   31982	TCP	NetQ Agent SSL communication
   32708	TCP	API Gateway
   22	TCP	SSH
   179	TCP	Calico networking (BGP)
   4	IP Protocol	Calico networking (IP-in-IP Protocol)
   4789	UDP	Calico networking (VxLAN)
   6443	TCP	kube-apiserver
   2379	TCP	etcd datastore

   Port 32666 is no longer used for the NetQ UI.

3. Download the NetQ images.

   1. On the NVIDIA Licensing Portal, log in to your account.
      
   2. Select Software Downloads from the menu.
   3. Click Product Family and select NetQ.
   4. Locate the NetQ SW 4.2 KVM Cloud image and select Download.
   5. If prompted, agree to the license agreement and proceed with the download.

4. 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.

   This example shows the VM setup process for a system with Libvirt and KVM/QEMU installed.

5. Log in to the VM and change the password.

   Use the default credentials to log in the first time:

   • Username: cumulus
   • Password: cumulus

   $ ssh cumulus@<ipaddr>
   Warning: Permanently added '<ipaddr>' (ECDSA) to the list of known hosts.
   Ubuntu 18.04.5 LTS
   cumulus@<ipaddr>'s password:
   You are required to change your password immediately (root enforced)

   Memory usage: 5%                IP address for eth0: <ipaddr>
   Swap usage:   0%
   WARNING: Your password has expired.
   You must change your password now and login again!
   Changing password for cumulus.
   (current) UNIX password: cumulus
   Enter new UNIX password:
   Retype new UNIX password:
   passwd: password updated successfully
   Connection to <ipaddr> closed.
   

   Log in again with your new password.

   $ ssh cumulus@<ipaddr>
   Warning: Permanently added '<ipaddr>' (ECDSA) to the list of known hosts.
   Ubuntu 18.04.5 LTS
   cumulus@<ipaddr>'s password:
     System information as of Thu Dec  3 21:35:59 UTC 2020
     System load:  0.07              Processes:           121
     Usage of /:   8.1% of 61.86GB   Users logged in:     0
     Memory usage: 5%                IP address for eth0: <ipaddr>
     Swap usage:   0%
   Last login: Thu Dec  3 21:35:43 2020 from <local-ipaddr>
   cumulus@ubuntu:~$
   

6. Verify the platform is ready for installation. Fix any errors indicated before installing the NetQ software.

   cumulus@hostname:~$ sudo opta-check-cloud

7. 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

The final step is to install and activate the NetQ software using the the CLI:
