strace says:

getcwd("/home/avi/kvm/linux-2.6"..., 4096) = 24
...
[no chdir]
...
open("kernel/arch/x86/kvm/kvm-intel.ko", O_RDONLY) = -1 ENOENT (No
such file or directory)

That "kernel/" looks like it was meant for /lib/modules, not a kernel
tree. If I run 'perf report' from /lib/modules/2.6.31 I see vmx_vcpu_run.
