[Bug 2129178] Re: Can not boot qemu VMs using ParaVitual SCSI controllers with Ubuntu 24.04

[Lukas Märdian]

Thanks for raising this issue.

Indeed, the support for PVSCSI has been disabled in the upstream
project, ahead of the stable202208 release, which means it's still
working in Ubuntu 22.04 (Jammy), but not working on 24.04+ (Noble+).

This was a conscious decision by the upstream maintainers, due to a lack
of maintainers for those drivers
(https://github.com/tianocore/edk2/commit/57783adfb579da32b1eeda77b2bec028a5e0b7b3):

OvmfPkg: Change default to disable MptScsi and PvScsi

The email addresses for the reviewers of the MptScsi and
PvScsi are no longer valid.  Disable the MptScsi and PvScsi
drivers in all DSC files until new maintainers/reviewers can
be identified.
"""

In addition to that, the definitions were moved to a new
‎OvmfPkg/Include/Dsc/OvmfOptHwDefines.dsc.in file, but remain disabled
by default
(https://github.com/tianocore/edk2/commit/faf600ccc76cf235c399d866ba7db52da8cea46c).

We could re-enable those drivers in Ubuntu (or maybe Debian), but would
do so without the support of the upstream project.

I will bring this up for discussion with the Ubuntu virtualization team.

Bug description:
  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.
