Hi,
first you can take a look at that file by doing something like "nano
/proc/sys/kernel/perf_event_paranoid".

So try to run this command as root:
"echo -1
a quick update:
Gem5 forum said KVM gurantee to work with native Linux machine.
But I am runing Gem5 with VM of Ubuntu, so guess there is no solution yet for
the issue of ‘PerfKvmCounter::attaach failed (2)“ on my machine

straight away. I would strongly suggest running on the host machine if
possible
If you have a X86 linux system you may be able to use KVM but it's not

yes, I am installing Ubuntu OS on X86 system, giving up VM.
