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.

    ResourceMinimum Requirement
    ProcessorFour (4) virtual CPUs
    Memory8 GB RAM
    Local disk storageFor NetQ 3.2.x and later: 64 GB (2 TB max)
    For NetQ 3.1 and earlier: 32 GB (2 TB max)
    Network interface speed1 Gb NIC
    HypervisorKVM/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 NumberProtocolComponent Access
    4IP ProtocolCalico networking (IP-in-IP Protocol)
    22TCPSSH
    179TCPCalico networking (BGP)
    443TCPNetQ UI
    2379TCPetcd datastore
    4789UDPCalico networking (VxLAN)
    6443TCPkube-apiserver
    8443TCPAdmin UI
    31980TCPNetQ Agent communication
    31982TCPNetQ Agent SSL communication
    32708TCPAPI Gateway

    Port 32666 is no longer used for the NetQ UI.

  3. Download the NetQ images.

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

    For enterprise customers, if you do not see a link to the NVIDIA Licensing Portal on the NVIDIA Application Hub, contact NVIDIA support.


    For NVIDIA employees, download NetQ directly from the NVIDIA Licensing Portal.

  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)

    Log in again with your new password.

    $ ssh cumulus@<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 CLI:
