• What is the cause and solution for SAP error message VIRT023 - CPU Virtualization Virtual System ?

  The SAP error message VIRT023 typically relates to issues with CPU virtualization in a virtualized environment. This error can occur in systems that are running SAP applications on virtual machines (VMs) and may indicate that the virtual system is not configured correctly for CPU virtualization.
  Cause:
  
  CPU Virtualization Not Enabled: The most common cause of this error is that CPU virtualization features (such as Intel VT-x or AMD-V) are not enabled in the BIOS/UEFI settings of the physical host machine.
  Insufficient Resources: The virtual machine may not have been allocated sufficient CPU resources or may be overcommitted in terms of CPU usage.
  Hypervisor Configuration: There may be issues with the hypervisor configuration that prevent proper CPU virtualization.
  SAP Kernel Issues: Sometimes, the error can be related to the version of the SAP kernel or other components that may not be compatible with the virtualization settings.
  
  Solution:
  
  
  Enable CPU Virtualization in BIOS/UEFI:
  
  Restart the physical server and enter the BIOS/UEFI settings.
  Look for options related to CPU virtualization (Intel VT-x, AMD-V) and ensure they are enabled.
  Save the changes and reboot the server.
  
  
  
  Check VM Configuration:
  
  Ensure that the virtual machine is configured with adequate CPU resources. This includes checking the number of virtual CPUs assigned to the VM.
  Verify that the VM is not overcommitted in terms of CPU resources.
  
  
  
  Review Hypervisor Settings:
  
  Check the settings of the hypervisor (e.g., VMware, Hyper-V, KVM) to ensure that it is configured correctly for CPU virtualization.
  Make sure that the hypervisor supports the virtualization features required by the SAP system.
  
  
  
  Update SAP Kernel:
  
  Ensure that you are using a compatible and up-to-date version of the SAP kernel and other components. Sometimes, upgrading to the latest version can resolve compatibility issues.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes or documentation that may address the specific error message and provide additional troubleshooting steps.
