RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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.
