Set Up Your KVM Virtual Machine for a Single Cloud Server

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

1. Verify that your system meets the VM requirements.

   Resource	Minimum Requirements
   Processor	Four (4) virtual CPUs
   Memory	8 GB RAM
   Local disk storage	64 GB
   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 required ports are open for communications.

   The OPTA must be able to initiate HTTPS connections (destination TCP port 443) to the netq.nvidia.com domain (*.netq.nvidia.com). You must also open the following ports on your NetQ OPTA:

   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	Nginx
   2379	TCP	etcd datastore
   4789	UDP	Calico networking (VxLAN)
   5000	TCP	Docker registry
   6443	TCP	kube-apiserver
   31980	TCP	NetQ Agent communication
   31982	TCP	NetQ Agent SSL communication
   32708	TCP	API Gateway

3. Download the NetQ image.

   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 4.12 KVM Cloud image and select Download.
   6. If prompted, read 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. Set up and configure your VM.

   KVM Example Configuration

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

   1. Confirm that the SHA256 checksum matches the one posted on the NVIDIA Application Hub to ensure the image download has not been corrupted.

      $ sha256sum ./Downloads/netq-4.12.0-ubuntu-20.04-tscloud-qemu.qcow2
      $ cd9723339eb44d0acb136f27c1d36653448ae475cc35fd8d5af58dcd7a5d15c9  ./Downloads/netq-4.12.0-ubuntu-20.04-tscloud-qemu.qcow2

   2. Copy the QCOW2 image to a directory where you want to run it.

      Tip: Copy, instead of moving, the original QCOW2 image that was downloaded to avoid re-downloading it again later should you need to perform this process again.

      $ sudo mkdir /vms
      $ sudo cp ./Downloads/netq-4.12.0-ubuntu-20.04-tscloud-qemu.qcow2 /vms/ts.qcow2

   3. Create the VM.

      For a Direct VM, where the VM uses a MACVLAN interface to sit on the host interface for its connectivity:

      $ virt-install --name=netq_ts --vcpus=4 --memory=8192 --os-type=linux --os-variant=generic --disk path=/vms/ts.qcow2,format=qcow2,bus=virtio,cache=none --network=type=direct,source=eth0,model=virtio --import --noautoconsole

      Replace the disk path value with the location where the QCOW2 image is to reside. Replace network model value (eth0 in the above example) with the name of the interface where the VM is connected to the external network.

      Or, for a Bridged VM, where the VM attaches to a bridge which has already been setup to allow for external access:

      $ virt-install --name=netq_ts --vcpus=4 --memory=8192 --os-type=linux --os-variant=generic \ --disk path=/vms/ts.qcow2,format=qcow2,bus=virtio,cache=none --network=bridge=br0,model=virtio --import --noautoconsole

      Replace network bridge value (br0 in the above example) with the name of the (pre-existing) bridge interface where the VM is connected to the external network.

      Make note of the name used during install as this is needed in a later step.

   4. Watch the boot process in another terminal window.

      $ virsh console netq_ts

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 20.04 LTS
   cumulus@<ipaddr>'s password:
   You are required to change your password immediately (root enforced)

   Memory usage: 5%                IP address for eth0: <ipaddr>

   WARNING: Your password has expired.

   Enter new UNIX password:

   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 20.04 LTS
   cumulus@<ipaddr>'s password:
     System information as of Thu Dec  3 21:35:59 UTC 2020
     System load:  0.07              Processes:           121

     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

8. Install and activate the NetQ software using the CLI:

Run the following command on your NetQ cloud appliance with the config-key obtained from the email you received from NVIDIA titled NetQ Access Link. You can also obtain the configuration key through the NetQ UI.

cumulus@<hostname>:~$ netq install opta standalone full interface eth0 bundle /mnt/installables/NetQ-4.12.0-opta.tgz config-key <your-config-key> [proxy-host <proxy-hostname> proxy-port <proxy-port>]

cumulus@hostname:~$ netq install opta standalone full interface eth0 bundle /mnt/installables/NetQ-4.12.0-opta.tgz config-key <your-config-key> pod-ip-range <pod-ip-range> service-ip-range <service-ip-range>

cumulus@hostname:~$ netq install opta standalone full ip-addr <ip-address> bundle /mnt/installables/NetQ-4.12.0-opta.tgz config-key <your-config-key>

Verify Installation Status

To view the status of the installation, use the netq show status [verbose] command. The following example shows a successful on-premises installation:
