Communication Manager Simplex requires two network interfaces
Communication Manager provides a KVM OVA that contains two qcow2 files:
  • system.qcow2
  • Var_Disk.qcow2
Note:
  • Disk encryption is currently not supported for Communication Manager LSP when installing with cockpit, use CLI script-based deployment methods only.
  • Always follow A1SC output for deployment of applications on the host(s). There should never be more than one instance of a specific application on the same host.
  • Deployment of applications MUST be performed one at a time, and delete the artifacts prior to deploying the next application.
Before you begin
  • Download the Communication Manager KVM image from PLDS to your computer.
  • Login to the ASP R6.0.x CLI with custadm credentials.
  • Ensure that the staging folder exist: sudo ls -ld /var/lib/libvirt/staging
    Ensure to remove the older images from the staging folder.
    Ensure sufficient space is available in the staging folder to copy the KVM image.
    If the staging folder does not exist, create it using the following commands:
    • sudo mkdir /var/lib/libvirt/staging
    • sudo chown custadm:wheel /var/lib/libvirt/staging
    The chown command now allows custadm to write into the staging directory with sudo. The permissions should look as follows:
    drwxr-x---. 2 custadm wheel 6 Oct 23 14:32 /var/lib/libvirt/staging
  • Copy the Communication Manager KVM image to the ASP R6.0.x host in /var/lib/libvirt/staging using the winscp tool and custadm credentials.
  • If not still in the CLI, login again to the ASP R6.0.x CLI with custadm credentials.
  • Ensure that the network bridge is configured during the KVM deployment.
Note:
All the following commands must be prefaced with “sudo”:
  • Run the following command to verify the Communication Manager KVM image available in the staging folder: sudo ls -lr /var/lib/libvirt/staging
  • Go to /var/lib/libvirt/staging folder, and run the following command to extract the ova file: sudo tar -xvf CMKVM-Simplex-010.2.0.0.229-e70-0.ova
    KVM OVA file extracts the following files:
    • CMKVM-Simplex-010.2.0.0.229-e70-0.ovf
    • CMKVM-Simplex-010.2.0.0.229-e70-0.mf
    • CMKVM-Simplex-010.2.0.0.229-e70-0.cert
    • system.qcow2
    • Var_Disk.qcow2
The extracted qcow2 images are in thin provision format. The qcow2 images MUST be converted to thick provision. When running the commands to convert to thick provision, a unique identifier can be added to the new qcow2 image. Avaya recommends to use VM name as a unique identifier. For example:
  • CM10.2[unique identifier]-system.qcow2
  • CM10.2[unique identifier]-Var_Disk.qcow2
The examples in this document will use the following:
  • CM10.2-system.qcow2
  • CM10.2-Var_Disk.qcow2
Go to /var/lib/libvirt/staging folder, and run the following command to convert system.qcow2 (thin) to CM10.2-system.qcow2 (thick) image:
  • sudo qemu-img convert -O qcow2 -o preallocation=full system.qcow2 CM10.2-system.qcow2
Go to /var/lib/libvirt/staging folder, and run the following command to convert Var_Disk.qcow2 (thin) to CM10.2Var_Disk.qcow2 (thick):
  • sudo qemu-img convert -O qcow2 -o preallocation=full Var_Disk.qcow2 CM10.2-Var_Disk.qcow2
To verify that the conversion is successful and verify the disk size, run the following commands:
  • sudo qemu-img info CM10.2-system.qcow2
    Disk size must display as 14 GB
  • sudo qemu-img info CM10.2-Var_Disk.qcow2
    Disk size must display as 50 GB
Go to /var/lib/libvirt/staging folder and run the following command to copy the CM10.2-system.qcow2 and CM10.2-Var_Disk.qcow2 to the /var/lib/libvirt/images directory:
  • sudo cp CM10.2-system.qcow2 CM10.2-Var_Disk.qcow2 /var/lib/libvirt/images
Go to /var/lib/libvirt/images directory and run the following command to verify the qcow2 images are present:
  • sudo ls –lrt
From the /var/lib/libvirt/images directory, run the following command to change the owner and permissions to 640 on the files:
  • sudo chown qemu:qemu CM10.2-system.qcow2
    sudo chown qemu:qemu CM10.2-Var_Disk.qcow2
    sudo chmod 640 CM10.2-system.qcow2
    sudo chmod 640 CM10.2-Var_Disk.qcow2
Go to /var/lib/libvirt/staging directory and remove all the extracted images and converted images. This is important to ensure that there is sufficient space for future deployments of KVM images. Do NOT remove files from the “images” directory.
  • cd /var/lib/libvirt/staging
    sudo ls -lr
    sudo rm *CM*
    sudo rm system.qcow2 Var_disk.qcow2

Next steps
On first boot of the Communication Manager virtual machine, login to the virtual console using the craft/craft01 and provide the configuration and networking parameters.
Follow the Configuration steps described in the Communication Manager 10.2 deployment guide for standard Communication Manager configuration. These steps are the same regardless of the underlying hypervisor.
Application of Communication Manager Feature Packs, Service Packs, SSPs, Patches should then be performed. Note that these will need to be done using the Communication Manager CLI or Communication Manager SMI. SDM and SDM Client cannot currently be used with the new KVM on RHEL 8.10 hypervisor.
Existing instructions for installation of these artifacts using the CLI and UI are applicable. Note that the “snapshot” functionality present in ASP R5.1.x and earlier is replaced with an equivalent feature, titled Virtual Machine Backup.
