Re: [gem5-users] PerfKvmCounter Error
You need to run that command *on the host*, not on the guest.

Re: [gem5-users] PerfKvmCounter Error
Yes I did but still I am getting the same error message. I have tried echo "12345" | echo -1 > /proc/sys/kernel/perf_event_paranoid and echo "12345" | sudo sysctl -w kernel.perf_event_paranoid=1 in the equivalent file to npb-install.sh.

Re: [gem5-users] PerfKvmCounter Error
Did you do what the error suggests? This error may be caused by a too restrictive setting in the file '/proc/sys/kernel/perf_event_paranoid' The default value was changed to 2 in kernel 4.6 A value greater than 1 prevents gem5 from making the syscall to perf_event_open. You need to run something like the following (as root). # echo -1 > /proc/sys/kernel/perf_event_paranoid Cheers.

Re: [gem5-users] PerfKvmCounter error
Glad you found it. How to check gem5 version: git log. You must build learn to build your own from source and do it often, or else it becomes hard to give help.

Hi Ciro, I am using the image and kernel provided from the gem5 website, see the command line below. Not sure how to check the gem5 version, but I downloaded it 3 months ago. build/X86/gem5.opt configs/example/fs.py --disk-image=linux-x86.img --cpu-type=X86KvmCPU --kernel=x86_64-vmlinux-2.6.22.9 On Sat, Jul 14, 2018 at 8:19 AM, Ciro Santilli wrote: > What is your image, kernel, gem5 revision, full gem5 command line, are > there any terminal messages. > > On Sat, Jul 14, 2018 at 2:43 AM, Ryan Wang wrote: > >> Hi, >> I was trying to use x86KvmCPU, and got a panic in the beginning of the >> run: panic: PerfKvmCounter::open failed (13) >> >> I saw that there are some patches from Jason that should solve a >> different error seen by some others, which I don't think related to this. >> I have kvm enabled in my machine and I can run qemu in kvm mode without >> problem. >> >> Has anyone seen this before?

What is your image, kernel, gem5 revision, full gem5 command line, are there any terminal messages.
