Patch sent upstream: https://lists.gnu.org/archive/html/qemu-devel/2020-01/msg00850.html QEMU has been recently split into sub-components and as a one-time operation to avoid breakage of tools, we are setting the QEMU sub-component of this BZ to "General". Please review and change the sub-component if necessary the next time you review this BZ. Thanks Tested this bug with qemu-kvm-4.2.0-13.module+el8.2.0+5898+fb4bceae.x86_64

Hi Stefan,
Is it expected result?

You need to install the systemtap packages.
Verified bug with qemu-kvm-4.2.0-13.module+el8.2.0+5898+fb4bceae.x86_64 and 4.18.0-183.el8.x86_64 /usr/bin/qemu-trace-stap list /usr/libexec/qemu-kvm acpi_pci_down_read acpi_pci_ej_write acpi_pci_eject_slot acpi_pci_features_read acpi_pci_rmv_read ..... wct_cmd_re wct_cmd_sp wct_cmd_st wct_cmd_ts wct_init wct_speed x86_iommu_iec_notify The fixed qemu-kvm works. So set this bug as verfied. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
