To install SBC software on a virtual machine (VM), you must first create a VM and allocate its resources (for example CPU, memory, and NICs), as well as configure a datastore to contain the SBC operating system and application software.

To create a new SBC SWe KVM instance, perform the following steps.

1. Perform the following to export the display on your desktop if you are remotely accessing the KVM host system.

   1. Log on to KVM host system through SSH and telnet client such as PuTTY using the following command:

      Code Block
      language none
      export DISPLAY=<system_IP>:0.0

      where <system_IP> is the system IP address where GUI is exported for display.
      
      

   2. Enter the following command to launch the virtual machine manager (virt manager) on your system.

      Code Block
      language none
      virt-manager

      
      

      Info
      Ensure Xserver is running on the host system to import the display on your desktop.

      
      

2. Click New to create a new VM.

      The VM configuration screen displays.

9. Perform the following steps to configure the VM settings
   1. In the left pane, click CPUs. The corresponding processor options are displayed.
      
      1. In the CPUs section,
         
         1. Type the required number of CPUs in the Current allocation field.

         2. Type the required number of CPUs in the Maximum allocation field.

            Info
            By default the Current allocation and Maximum allocation fields are set to 1, change them accordingly to the requirement.

            
            

            Info
            The Model field displays the host CPU configuration running on the host system like SandyBridge or Nehalem.

            
            

      2. In the Configuration section, choose host-passthrough as model.
      3. In the Topology section:
         
         1. Select the Manually set CPU topology checkbox.
         2. In the Sockets field, enter 1 as the number of sockets required for the instance.
         3. In the Cores field, enter 2 as the number of cores required for the instance.

         4. In the Threads field, enter 2 as the number of threads required for the instance.

         5. Click Apply. 

            Info
            If your system supports hyperthreading then you enable hyperthreading by mentioning a thread number. This example configures 4 hyperthreaded cores (4 vCPUs).
