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.
Refer to Downloading the SBC SWe Lite Package for On-Premises Deployment prior to performing this procedure. The SBC SWe Lite supports one Network Management interface and up to four Network Media interfaces. The minimal networking configuration (one management and one media interface) requires two bridge interfaces configured on Hyper Visor host. To support maximum 1+4 configuration, Hyper Visor host must have five bridge interfaces configured prior to the Virtual Machine (VM) installation. Changing disk or network drivers post-deployment is not recommended. Start the Virtual Machine Manager. From the Create New Virtual Machine dialog, select Import existing disk image and click Forward. Select Debian Squeeze from the Version drop-down menu . Click Browse and navigate to the location of the disk image. From the Choose Storage Volume dialog, select file SBCSWeLite-disk.qcow2, then click Choose Volume. Click Forward. Set Memory (RAM) field to 1024, 1536, or 2560. Set CPUs to 1, 2, 4, or 10 and click Forward. From the New VM dialog, select the applicable network from the Network selection drop-down menu, and click Finish. This network is used for Management Interface. By default, the Randon Number Generator (RNG) device is present in the SBC SWe Lite. Through the Virtual Manager options/configuration, verify RNG is present. If it is not displayed, install manually as follows: In the new pop-up window, select Disk 1. Expand Advanced options and select VirtIO (for Releases 7.0 and above) or IDE (for Release 6.1) from the Disk bus drop-down menu. For 7.0 Release and later: Use virtio as the Network Interface Device Model. Select virtio from the Device model drop-down menu, then click Apply. Repeat the preceding steps for additional Network Interfaces. The first Virtual NIC must use a dedicated bridge (Network source). The Network source can then be used to configure the four remaining Virtual NICs. Ribbon recommends that all customers review and, if necessary, optimize their Network Interface configurations before proceeding. Failure to do so could lead to interface mapping issues. See Mapping Network Interfaces and then return to this section. To achieve the maximum performance of the CPUs, configure the CPUs so that the Model field is set to host-passthrough. 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. From the Virtual Machine dialog, click Begin installation. The configured VM starts automatically as shown below. Click Prerequisites
