Create the Fabric Services System virtual machine

To deploy a Fabric Services System node as a virtual machine, complete the appropriate procedure for your deployment scenario:

Creating the VM on bridged networks on KVM

Complete the following steps to deploy a Fabric Services System node as a virtual machine on KVM. The OAM network is referred to as br0 and the Fabric Management network is referred to as br1.

  1. Ensure that the virt-install tool is installed on the KVM hypervisor.
    If you need to install the tool, use the following command:
    # yum install virt-install
  2. Copy the base OS image to the hypervisor in the appropriate location where the virtual disks should be stored.
  3. Resize the base OS image.
    By default, the Fabric Services System base OS image comes with a small partition to lower the download size of the image. To assign the appropriate size to the image, execute the following command:
    # qemu-img resize /path/to/fss-node01.qcow2 200G

    The actual root partition is resized later in the procedure.

  4. Optional: If the node is also going to be used as a storage node, create the necessary extra disk for the storage cluster to be formed.
    Create the virtual disk using the following command:
    # qemu-img create -f qcow2 /path/to/fss-node01-storage.qcow2 300G
  5. Create the virtual machine.
    The following command creates a node that also serves as a storage node. If a storage node is not needed, omit the second line that starts with --disk.
    # virt-install --import --name fss-node01 \
     --memory 65536 --vcpus 32 --cpu host \
     --disk /path/to/fss-node01.qcow2,format=qcow2,bus=virtio \
     --disk /path/to/fss-node01-storage.qcow2,format=qcow2,bus=virtio \
     --network bridge=br0,model=virtio \
     --network bridge=br1,model=virtio \
     --os-variant=centos7.0 \

Creating the VM on bridged network on VMware vSphere

You can use one of the following methods to deploy the VM on VMware vSphere:
  • the VMware vSphere vCenter or ESXi UI

    For instructions, see Deploy an OVF or OVA Template in the VMware vSphere documentation.

  • the VMware Open Virtualization Format Tool CLI

    The following section provides an example of how to use the VMware OVF Tool CLI.

  1. Download and install the latest version of the VMware OVF Tool from the VMware Developer website.
  2. Display details about the OVA image.
    Execute the ovftool command with just the OVA image name as argument.
    $ ovftool fss-baseos_v22.8.1-16.ova
    OVF version:   1.0
    VirtualApp:    false
    Name:          fss-baseos
    Download Size:  2.03 GB
    Deployment Sizes:
      Flat disks:   128.00 GB
      Sparse disks: 3.64 GB

          Connection:     FABRIC
      File:  fss-baseos-disk1.vmdk
  3. Deploy the OVA image using the OVF tool.

    For details about command line arguments, see the OVF tool documentation from the VMware website.

    Make sure to use thick provisioning for the disk and to connect all the interfaces to a network. The secondary interface can be disconnected and disabled after the deployment and before yo power on.
    $ ovftool --acceptAllEulas -dm=thick -ds=VSAN -n=fss-node01 --net:"OAM=OAM-network" --net:"FABRIC=Fabric-network" fss-baseos_v22.8.1-16.ova vi://administrator%40vsphere.local@vcenter.domain.tld/My-Datacenter/host/My-Cluster/Resources/My-Resource-Group

    Completed successfully
  4. Optional: If you are using this node as a storage node, create the necessary extra disk for the storage cluster to be formed.
    To create the extra disk, edit the VM in VMware vCenter and add a new 300GB disk.
  5. Enable 100% resource reservation for both CPU and memory for the VM.
    You can configure the resource reservation for CPU and memory by editing the VM in vCenter.
