  Having difficulties with booting EFI qemu VMs using PV - SCSI controllers 
with ubuntu 24.04.
  
  Seems as though this driver support has been removed from the efi fw:
  https://edk2.groups.io/g/devel/message/91861
  
  Asking for guidance how to proceed and if these drivers can be re-
  enabled in the ovmf package for ubuntu.
