Issue/Introduction

After deploying your new virtual appliance in your vSphere environment and powering on the virtual machine you see the following message No operating system found

No operating system found

Environment

The following Symantec Network Protection virtual appliances require the boot mode be set to EFI:

  • SSLV-VA (SV-VA-*)
  • Reporter (RP-V*)
  • Management Center (MC-V*)
  • Content Analysis (CAS-VA-*)

Cause

The virtual appliances uses EFI/UEFI (Extensible Firmware Interface) as the boot loader if the boot option is set to BIOS the appliance will fail to boot as it does not support BIOS.

Resolution

The below procedure is for modifying the boot option through vCenter Server using the vSphere client on version 6.5/6.7. If using a different version the procedure may vary and you will need to consult the appropriate VMWare documentation/support for further assistance.
