Hi All,

I am very new to rr, and trying to use it.

I did all installation steps as mention below in RHEL7.
https://github.com/mozilla/rr/wiki/Building-And-Installing

now executing a program below program:

#include<stdio.h>
int main()
{
  int i = 10;

  printf("integer value = %d",i);
  while (1)
  {
    printf("XXXXXXXXX");
  }

  return 0;
}

But while execution getting below error

rr -F record a.out
rr: Saving the execution of `a.out' to trace directory `/root/.local/share/rr/a.out-4'.

rr internal recorder error: Performance counter doesn't seem to be working. Are you perhaps running rr in a VM but didn't enable perf-counter virtualization?


Can u guide me to resolve the below issue.

Best regards,
xxxx
