In this section:

SWe Lite supports the following (depending on your license):

• For Memory (RAM), valid settings are 1 GiB (1024 MiB), 1.5 GiB (1536 MiB), or 2.5 GiB (2560 MiB).
• For vCPUs, valid settings are 1, 2, 4 or 10 vCPUs.

For detailed information, refer to SBC SWe Lite Hardware and Software Requirements.

For adding vCPUs or increasing memory on a SWe Lite upgraded to Release 7.0, refer to Changing vCPU and Increasing Memory/VM Size.

For Release 8.1 and later, the SBC uses a single QCOW2 image file instead of multiple QCOW2 image files. As a result, the SBC cannot be downgraded from Release 8.1 and later to Release 8.0 and earlier.

Prerequisites

Refer to Downloading the SBC SWe Lite Package for On-Premises Deployment prior to performing this procedure.

Limitations

• Disk and network drivers must be selected during deployment only.

• Changing disk or network drivers post-deployment is not recommended.

Configure CPU Model

To achieve the maximum performance of the CPUs, configure the CPUs so that the Model field is set to host-passthrough.

Configure SR IOV

The Single Root I/O Virtualization (SR-IOV) is a type of PCI device that enables a physical device (such as a single NIC device) to share to multiple virtual functions; this functionality improves the performance of the I/O. SR-IOV configuration in KVM can share the physical port with multiple virtual machines.

For the configuration steps required to enable SR-IOV networks on the KVM platform, refer to Red Hat Enterprise's PCI Device Assignment with SR-IOV Devices.

Finalize Installation

1. From the Virtual Machine dialog, click Begin installation.
