I have only tested this for virtio-gpu-pci, but I think it's safe to assume that most (if not all) virtio-*-pci behave the same way. [1] Actually a CentOS Stream 9 container, but it shouldn't make any difference for the purpose of this bug report. --- Additional comment from Daniel Berrangé on 2022-11-30 16:11:29 UTC --- > Manually installing the qemu-kvm-device-display-virtio-gpu package > makes the issue go away, but since virtio-gpu is apparently needed > for virtio-gpu-pci to work, this dependency should be made explicit > in the spec file. Right, instantiating a 'virtio-gpu-pci' device has a hard dependency on instantiating a 'virtio-gpu' device So we need a 'Requires: qemu-kvm-device-display-virtio-gpu' to be present in the 'qemu-kvm-device-display-virtio-gpu-pci' sub-RPM Likewise for the -gl / -gl-pci variants. Most modules don't need such RPM dependencies since they are self-contained. The virtio device modules are special because the virtio transport is pluggable, so the -pci device is an add-on to the generic device. --- Additional comment from Miroslav Rezanina on 2022-11-30 20:06:13 UTC --- (In reply to Daniel Berrangé from comment #1) > > Manually installing the qemu-kvm-device-display-virtio-gpu package > > makes the issue go away, but since virtio-gpu is apparently needed > > for virtio-gpu-pci to work, this dependency should be made explicit > > in the spec file. > > Right, instantiating a 'virtio-gpu-pci' device has a hard dependency on > instantiating a 'virtio-gpu' device > > So we need a 'Requires: qemu-kvm-device-display-virtio-gpu' to be present in > the 'qemu-kvm-device-display-virtio-gpu-pci' sub-RPM > > Likewise for the -gl / -gl-pci variants. > > Most modules don't need such RPM dependencies since they are self-contained. > The virtio device modules are special because the virtio transport is > pluggable, so the -pci device is an add-on to the generic device. Thanks for clarification, Daniel. I miss-read Andrea's report and not realize the problem is between modules subpackages and not in core subpackage. I'll prepare fix for this.
This bug appears to have been reported against 'rawhide' during the Fedora Linux 38 development cycle. Changing version to 38.
This message is a reminder that Fedora Linux 38 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora Linux 38 on 2024-05-21. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a 'version' of '38'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, change the 'version' to a later Fedora Linux version. Note that the version field may be hidden. Click the "Show advanced fields" button if you do not see it. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora Linux 38 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora Linux, you are encouraged to change the 'version' to a later version prior to this bug being closed.
Fedora Linux 38 entered end-of-life (EOL) status on 2024-05-21. Fedora Linux 38 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora Linux please feel free to reopen this bug against that version. Note that the version field may be hidden. Click the "Show advanced fields" button if you do not see the version field. If you are unable to reopen this bug, please file a new report against an active release. Thank you for reporting this bug and we are sorry it could not be fixed.
