This section describes a procedure for installation or upgrade of an SBC SWe 1:1 HA pair on KVM using a QCOW2 image file and an ISO config drive you create using the CLI tool createConfigDrive.py. The tool is contained within the tarball createConfigDrive-1.0.0.tar.gz (available as part of the release software bundle). It significantly improves the workflow for the installation and upgrade of SBC SWe on KVM as compared to the traditional procedure involving an ISO file, especially when an LSWU is performed.

Info

title	Note

The tool and the associated procedure are applicable only when using a QCOW2 file to deploy SBC SWe 8.1 or higher on KVM. For MRFP, you may use it to upgrade from SBC 7.2.x to SBC 8.0 or higher versions.
Starting with SBC 8.1, this is the recommended procedure for installation and upgrade of SBC SWe on KVM.

Info

title	Note

The procedure described in this section assumes and recommends that the active and standby instances are guests in two different KVM hosts.

Tip

title	Tip

For installation or upgrade of standalone instances, complete the steps for a single KVM host, rather than two hosts, and for only one instance, rather than both active and standby instances.

Prerequisites

Before performing an installation followed by an upgrade, execute the following steps:

Back up the system configuration and the data.
Ensure that you have root level access to the KVM hosts. For an HA pair, log on to both KVM hosts as root (or equivalent, with full administrative privileges).

On each KVM host, perform the following:

Download the release software bundle and untar it. The unpacked bundle contains the tarball createConfigDrive-1.0.0.tar.gz. Copy it to your home directory.
Code Block
# cp createConfigDrive-1.0.0.tar.gz ~/
Unpack the tarball createConfigDrive-1.0.0.tar.gz.
Code Block
# tar -xvzf createConfigDrive-1.0.0.tar.gz

Navigate to ~/createConfigDrive-1.0.0 and ensure both createConfigDrive.py and README.md are present. Open README.md in an editor such as vi to find more information on the createConfigDrive.py tool.

Code Block
# cd ~/createConfigDrive-1.0.0 # vi README.md

Info

title	Note

Ensure that the following packages that createConfigDrive.py requires are installed on the instances:

The Python package netaddr. If you have the Python package manager "pip" installed, use the command "pip install netaddr" to install the package.
Linux package:
- genisoimage
For Debian-based Linux distributions, use the command "sudo apt install <dependency>" to install the Linux packages.

Copy the QCOW2 images of the base build (for initial installation) and the build to which you want to upgrade to the /var/lib/libvirt/images directory.
Code Block
# cp <path_to_qcow2_image_file> /var/lib/libvirt/images
Create copies of the base and final builds in the /var/lib/libvirt/images directory. While executing the cp command, add the suffix "_cp1" and "_cp2" to the base and final build file names respectively. For example, the names of the copied files should be similar to "sbc-V08.01.00R000-connexip-os_07.00.00-A019_4684_amd64_cp1.qcow2" and "sbc-V08.01.00R000-connexip-os_07.00.00-A020_146_amd64_cp2.qcow2".
Code Block
# cd /var/lib/libvirt/images # cp <base_image_file_name>.qcow2 <base_image_file_name>_cp1.qcow2 # cp <final_image_file_name>.qcow2 <final_image_file_name>_cp2.qcow2

Installation

Tip

title	Tip

To perform only an upgrade, skip the procedure for installation.

Active Instance

Log on to the KVM host reserved for the active instance as root (or equivalent, with full administrative privileges), and execute the following steps:

Navigate to the ~/createConfigDrive-1.0.0 directory.
Code Block
# cd ~/createConfigDrive-1.0.0

Run the script createConfigDrive.py. For installation, you can run the script in either of two modes. The --cli option provides screen prompts after which you can enter configuration data for the deployment. The --file option requires you to pass the script a file, sbx.json, which must contain all the required configuration data in a json file format. Both options are shown below.

The --cli option:

Execute the following command to provide configuration data in response to prompts.
Code Block
# python createConfigDrive.py --cli

If you do not need an object for configuration, pass an empty string ("") as its value.

For reference, the possible values of some objects are as follows:

- installType: 1 - Standalone | 2 - HA

- mgtIpType: 1 - IPv4 | 2 - IPv6 | 3 - IPv4 + IPv6

- timezone: Refer to ~/createConfigDrive-1.0.0/README.md.

- sbctype: isbc | ssbc | msbc | tsbc | mrfp

Execute the following command:

Code Block
# python createConfigDrive.py --file ./input/sbx.json

The script executes and creates configuration drive images for both the active and standby instances. The file config_drive_kvm1.iso is for the active instance, and the file config_drive_kvm2.iso is for the standby instance. By default, the generated files are placed in the ~/createConfigDrive-1.0.0/output directory. Copy the file ~/createConfigDrive-1.0.0/output/config_drive_kvm1.iso to the directory /var/lib/libvirt/images.
Code Block
# cp ~/createConfigDrive-1.0.0/output/config_drive_kvm1.iso /var/lib/libvirt/images
The recommended deployment creates the standby instance on a different KVM host. Use the scp tool to securely copy the file to the remote location. Copy the file ~/createConfigDrive-1.0.0/output/config_drive_kvm2.iso to the /var/lib/libvirt/images directory of the standby instance's host.
Code Block
# scp -P 22 ~/createConfigDrive-1.0.0/output/config_drive_kvm2.iso root@<Standby_Host_IP_Address>:/var/lib/libvirt/images root@<Standby_Host_IP_Address>'s password: config_drive_kvm2.iso

Execute the following commands to change directories and then truncate the disk and create a mirror disk:

Code Block
# cd /var/lib/libvirt/images # truncate --size=30G active_evlog.qcow2

Tip

title	Tip

In the preceding command, "30G" is the size of the mirror disk in GB. Specify the size of the mirror disk as appropriate. Ensure that the size of the mirror disk does not exceed the maximum allowed size.

Create soft (symbolic) links for the base build that you want to install.

Code Block
# ln -s /var/lib/libvirt/images/<base_image_file_name>_cp1.qcow2 /var/lib/libvirt/images/KVM1.qcow2

Execute the following command to instantiate the active instance:

Code Block

# virt-install --name=KVM1 \

Upgrade

This section describes the procedure for offline upgrade of an HA pair of SBC SWe instances on KVM. The upgrade starts with the standby instance, followed by the active instance.

Info

title	Note

Starting with SBC 8.1, this is the recommended procedure for upgrading an SBC SWe instance on KVM.

Note

title	Caution

For LSWU, ensure that the base version and the version to which you are upgrading are LSWU-compatible.

Standby Instance

Log on to the KVM host for the current standby instance as root (or equivalent, with full administrative privileges), and execute the following steps:

Log on to the standby instance as root and stop the SBC application.
Code Block
# sbxstop
Switch back to the host, shut down the standby instance running as a KVM guest.
Code Block
# virsh shutdown <CE_name_of_Standby_instance>
Navigate to the /var/lib/libvirt/images directory of the host.
Code Block
# cd /var/lib/libvirt/images
Remove the soft (symbolic) link pointing to the base build that you used for installation.
Code Block
# rm -rf KVM2.qcow2
Ensure that you have the QCOW2 image file for the SBC version to which you want to upgrade in the /var/lib/libvirt/images directory.

Optionally, check the QCOW2 disk size and modify it if required. Usually, the disk size for the upgraded build is the same as the original disk size.

Code Block

#### Check for the virtual size of the disk. By default, the size of the new disk after the upgrade will be same.
# qemu-img info <qcow2_image_file_for_upgrade> | grep "virtual size"

#### Resize disk size for upgraded version
# qemu-img resize <qcow2_image_file_for_upgrade> +30G100G

Tip

title	Tip

In the preceding code snippet, "+30G100G" implies the new disk is 30GB 100GB larger than the original disk size. Ensure that the new disk size does not exceed the maximum allowed disk size.

Create a new soft (symbolic) link pointing to the build file to which you want to upgrade.
Code Block
# ln -s <qcow2_image_file_for_upgrade> KVM2.qcow2
Start the standby instance as a KVM guest.
Code Block
# virsh start <CE_name_of_Standby_instance>
The standby instance comes up with the upgraded version of the SBC SWe. Log on to the instance as root, and check the details of the upgraded version by executing the following command:
Code Block
# swinfo -v
After booting up, the standby instance attempts to synchronize with the active. To check the sync status, execute the following command:
Code Block
% show table system syncStatus

Active Instance

Log on to the KVM host reserved for the active instance as root (or equivalent, with full administrative privileges), and execute the following steps:

Log on to the active instance as root and stop the SBC application.
Code Block
# sbxstop
Switch back to the host, shut down the active instance running as a KVM guest.
Code Block
# virsh shutdown <CE_name_of_Active_instance>
Navigate to the /var/lib/libvirt/images directory of the host.
Code Block
# cd /var/lib/libvirt/images
Remove the soft (symbolic) link pointing to the base build that you used for installation.
Code Block
# rm -rf KVM1.qcow2
Ensure that you have the QCOW2 image file for the SBC version to which you want to upgrade in the /var/lib/libvirt/images directory.

Optionally, check the QCOW2 disk size and modify it if required. Usually, the disk size for the upgraded build is the same as the original disk size.

Code Block

#### Check for the virtual size of the disk. By default, the size of the new disk after the upgrade will be same.
# qemu-img info <qcow2_image_file_for_upgrade> | grep "virtual size"

#### Resize disk size for upgraded version
# qemu-img resize <qcow2_image_file_for_upgrade> +30G100G

Tip

title	Tip

In the preceding code snippet, "+30G100G" implies the new disk is 30GB 100GB larger than the original disk size. Ensure that the new disk size does not exceed the maximum allowed disk size.

Create a new soft (symbolic) link pointing to the build file to which you want to upgrade.
Code Block
# ln -s <qcow2_image_file_for_upgrade> KVM1.qcow2
Start the active instance as a KVM guest.
Code Block
# virsh start <CE_name_of_Active_instance>
The active instance comes up with the upgraded version of the SBC SWe. Log on to the instance as root, and check the details of the upgraded version by executing the following command:
Code Block
# swinfo -v
Once the upgrade procedure for both standby and active instances is complete, the instances will automatically synchronize as an HA pair. To check the sync status, log on to the instance and execute the following command:
Code Block
% show table system syncStatus
