| kata-irc-bot | <feng.wang> Has anyone tried to run linux perf inside the kata container? After build the perf package and enabling the pmu, I’m getting the following error: ```root@csi-test-57cd7bb898-m9wbs:/# ./perf stat -C 0 -- sleep 10 Error: The sys_perf_event_open() syscall returned with 22 (Invalid argument) for event (slots). /bin/dmesg | grep -i perf may provide additional information.``` Any idea? And here are the dmesg events related to perf: | 21:02 |
