• What is the cause and solution for SAP error message VIRT106 - Minimum Number of Physical CPUs Configured (Reserved) ?

  The SAP error message VIRT106: Minimum Number of Physical CPUs Configured (Reserved) typically indicates that the SAP system is not able to allocate the minimum number of physical CPUs required for its operation. This can occur in virtualized environments where the SAP system is running on virtual machines (VMs) and the underlying physical resources are not configured correctly.
  Cause:
  
  Insufficient Physical CPUs: The virtual machine may not have enough physical CPU resources allocated to meet the minimum requirements set by the SAP system.
  Configuration Issues: The configuration of the virtual machine may not align with the SAP system's requirements, such as the number of virtual CPUs (vCPUs) not matching the expected physical CPU allocation.
  Resource Reservations: In some virtualization environments, there may be resource reservations that prevent the VM from accessing the required number of physical CPUs.
  Licensing Issues: Sometimes, licensing restrictions may limit the number of CPUs that can be allocated to the SAP system.
  
  Solution:
  
  Check CPU Allocation: Verify the number of physical CPUs allocated to the virtual machine. Ensure that it meets the minimum requirements specified by SAP for the particular system you are running.
  Adjust VM Configuration: If the VM is configured with fewer vCPUs than required, increase the number of vCPUs in the VM settings. Make sure that the underlying physical host has enough resources to support this change.
  Resource Reservations: If there are resource reservations in place, adjust them to allow the VM to access the necessary CPU resources.
  Review SAP Notes: Check the SAP Notes relevant to your version of SAP for any specific recommendations or patches that may address this issue.
  Consult Documentation: Refer to the SAP Hardware and Software Requirements documentation for your specific SAP application to ensure compliance with the minimum requirements.
  Contact Support: If the issue persists after making the necessary adjustments, consider reaching out to SAP support for further assistance.
  
  Related Information:
  
  SAP Notes: Look for SAP Notes related to CPU requirements and virtualization best practices.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and what solutions they have implemented.
  Virtualization Documentation: Review the documentation for your virtualization platform (e.g., VMware, Hyper-V) for best practices on configuring VMs for SAP workloads.
  
  By addressing the underlying causes and ensuring that the configuration aligns with SAP's requirements, you should be able to resolve the VIRT106 error message.
