[gem5-users] PerfKvmCounter error

Discussion:

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? Does anyone have any clue of which part I
could have missed?

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

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

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.
