Tip of the Day: Virtualized UEFI


Today’s Tip…

In yesterday’s tip, I talked about Generation 2 VMs and how many emulated devices were being removed.? At the top of the list was ‘BIOS’.? In Generation 2 VMs, the BIOS has been replaced with virtualized firmware.

  • Required to virtualize ‘boot to GPT’
  • Replaces vBIOS
  • Allows for synthetic booting (either network or storage)
  • Required for secure boot and measured boot in a virtualized environment
  • Available in Generation 2 VMs only
  • Removes the need to add a legacy NIC just to be able to PXE boot
  • Improves VM startup time
