Description Andrea Bolognani 2021-11-12 18:02:24 UTC 
Looking at how the QEMU package is split into components in CentOS
Stream 9 and comparing it to Fedora 35, we can see that they are
quite a bit different.

Of course most of the differences can be attributed to Fedora
enabling all possible QEMU features/devices while the CentOS Stream
build is more selective, but there are still a significant number
that don't fall into that category. Here are the ones that I've
spotted - there might be more.


usbredir

Contents are the same, but the subpackage name is completely
different.

  [cs9]# rpm -ql qemu-kvm-hw-usbredir | grep -v build-id
  /usr/lib64/qemu-kvm/hw-usb-redirect.so

  [f35]# rpm -ql qemu-device-usb-redirect | grep -v build-id
  /usr/lib64/qemu/hw-usb-redirect.so

OpenGL

In CentOS Stream, a single subpackage encompasses the contents of two
separate Fedora subpackages.

  [cs9]# rpm -ql qemu-kvm-ui-opengl | grep -v build-id
  /usr/lib64/qemu-kvm/ui-egl-headless.so
  /usr/lib64/qemu-kvm/ui-opengl.so

  [f35]# rpm -ql qemu-ui-opengl | grep -v build-id
  /usr/lib64/qemu/ui-opengl.so
  [f35]# rpm -ql qemu-ui-egl-headless | grep -v build-id
  /usr/lib64/qemu/ui-egl-headless.so

virtio-gpu

Fedora has four separate subpackages for the various variants of the
device, whereas CentOS Stream ships all of them as part of the -core
subpackage. Note that in Fedora the -core subpackage doesn't contain
any module.

  [cs9]# rpm -ql qemu-kvm-core | grep virtio-gpu
  /usr/lib64/qemu-kvm/hw-display-virtio-gpu-gl.so
  /usr/lib64/qemu-kvm/hw-display-virtio-gpu-pci-gl.so
  /usr/lib64/qemu-kvm/hw-display-virtio-gpu-pci.so
  /usr/lib64/qemu-kvm/hw-display-virtio-gpu.so

  [f35]# rpm -ql qemu-device-display-virtio-gpu | grep -v build-id
  /usr/lib64/qemu/hw-display-virtio-gpu.so
  [f35]# rpm -ql qemu-device-display-virtio-gpu-gl | grep -v build-id
  /usr/lib64/qemu/hw-display-virtio-gpu-gl.so
  [f35]# rpm -ql qemu-device-display-virtio-gpu-pci | grep -v build-id
  /usr/lib64/qemu/hw-display-virtio-gpu-pci.so
  [f35]# rpm -ql qemu-device-display-virtio-gpu-pci-gl | grep -v build-id
  /usr/lib64/qemu/hw-display-virtio-gpu-pci-gl.so

virtio-vga

Fedora has a subpackage for each variant of the device, and so does
CentOS Stream - in a sense. In CentOS Stream, one of the variants is
part of the -common subpackage and the other one of the -core
subpackage. Note that in Fedora neither the -common subpackage nor
the -core subpackage contain any modules.

  [cs9]# rpm -ql qemu-kvm-common | grep virtio-vga
  /usr/lib64/qemu-kvm/hw-display-virtio-vga.so
  [cs9]# rpm -ql qemu-kvm-core | grep virtio-vga
  /usr/lib64/qemu-kvm/hw-display-virtio-vga-gl.so

  [f35]# rpm -ql qemu-device-display-virtio-vga | grep -v build-id
  /usr/lib64/qemu/hw-display-virtio-vga.so
  [f35]# rpm -ql qemu-device-display-virtio-vga-gl | grep -v build-id
  /usr/lib64/qemu/hw-display-virtio-vga-gl.so

USB host

Fedora has a package for it, whereas CentOS Stream includes it in the
-core subpackage. Note that in Fedora the -core subpackage doesn't
contain any module.

  [cs9]# rpm -ql qemu-kvm-core | grep usb-host
  /usr/lib64/qemu-kvm/hw-usb-host.so

  [f35]# rpm -ql qemu-device-usb-host | grep -v build-id
  /usr/lib64/qemu/hw-usb-host.so

virtiofsd

This is the one instance in which CentOS Stream is ahead of Fedora:
while the former has a separate package for the daemon, the latter
includes it in the -common subpackage.

  [cs9]# rpm -ql qemu-virtiofsd | grep -v build-id
  /usr/libexec/virtiofsd
  /usr/share/man/man1/virtiofsd.1.gz
  /usr/share/qemu/vhost-user/50-qemu-virtiofsd.json

  [f35]# rpm -ql qemu-common | grep virtiofsd
  /usr/libexec/virtiofsd
  /usr/share/man/man1/virtiofsd.1.gz
  /usr/share/qemu/vhost-user/50-qemu-virtiofsd.json


I believe that these differences in packaging between Fedora and
CentOS Stream / RHEL constitute an annoyance to users and upstream
developers that want to target both, and that we should address them
before RHEL 9 hits GA.

Comment 1 Andrea Bolognani 2022-01-03 17:54:38 UTC 
Hi Danilo,

any updates on this?

I see the QEMU package in CentOS Stream 9 has been updated to 6.2.0
with

  https://gitlab.com/redhat/centos-stream/rpms/qemu-kvm/-/commit/037e637fa30d6650f9c990c860a070aa9c15edb4

so this seems like a great time to reorganize the subpackages.

Thanks!

Moving to Mirek, let's discuss this in our next meeting.
Comment 8 Yanan Fu 2022-02-07 06:51:36 UTC 
QE bot(pre verify): Set 'Verified:Tested,SanityOnly' as gating/tier1 test pass.
