perfkvmcounter ::附件失败（1）docker中运行GEM5 x86全系统模式的错误

Question

我正在从 x86-ubuntu-run-with-kvm.py 示例脚本时，出现了错误：

我已经检查了有关资源文件的MD5SUM值<代码>“ x86-linux-kernel-5.4.49” 和“ x86-ubuntu-18.04-img” ，它们的值与“ NOROFOLL NOREFERRER”>资源

顺便说一句，我运行码头

 sudo docker run --name m00xxx --device=/dev/kvm --volume /usr2/m00xxx/gem5:/home/gem5 -P -it gem5test:0614 

，然后从。

我从GDB获得了回溯：

您应该将perf_event_paranoid设置为“ -1”。在您的主机计算机类型中：

echo "-1" | sudo tee /proc/sys/kernel/perf_event_paranoid
