Issue

Description of problem: When RHEL 8.6 is installed and then the RT kernel is installed using the yum method, the kernel-rt-kvm RPM is not installed by default. See: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux_for_real_time/8/html-single/installing_rhel_8_for_real_time/index#proc_installing-red-hat-enterprise-linux-for-real-time-using-yum_assembly_installing-rhel-for-real-time If tuned is then used to apply the cpu-partitioning profile, there is a silent failure with the following errors (in /var/log/tuned/tuned.log): 2022-12-15 11:13:30,086 INFO tuned.plugins.plugin_script: calling script '/usr/lib/tuned/cpu-partitioning/script.sh' with arguments '['start']' 2022-12-15 11:13:30,132 ERROR tuned.plugins.plugin_script: script '/usr/lib/tuned/cpu-partitioning/script.sh' error output: 'modinfo: ERROR: Module kvm not found. modinfo: ERROR: Module kvm not found. modinfo: ERROR: Module kvm_intel not found.' Note that this is a silent failure - it looks like the tuned profile was applied successfully, but the /usr/lib/tuned/cpu-partitioning/script.sh exits early and doesn't complete. Version-Release number of selected component (if applicable): tuned-profiles-cpu-partitioning-2.19.0-1.1.20221013git12fa4d58.el8fdp.noarch How reproducible: Always Steps to Reproduce: 1. Install RHEL 8.6 2. Install RT kernel 3. Apply tuned cpu-partitioning profile Actual results: The cpu-partitioning profile is not applied properly. The only indication of failure is in the tuned logs. Expected results: The cpu-partitioning profile is applied properly. Additional info: The workaround is to enable the rhel-8-for-x86_64-nfv-rpms repo and install the kernel-rt-kvm RPM. I'm not sure if that would be available to all users? Also, I don't think this happened in RHEL 8.5 (but I'm not 100% sure about that).
