Sorry for a late response as I was distracted by another task in the
last few weeks. Today, I compiled and installed QEMU 1.7.0 from source,
but no luck with this. Tested on a different machine with different
kernel version: 3.2, I got the same results.
Btw, I found bug 798936 which describes similar problem here:
bugzilla.redhat.com/show_bug.cgi?id=798936
it seems like this problem has been detected and resolved in the past.
Do you know what Linux distro/kernel that the bug was resolved on? Maybe
I can try that instead of using ubuntu to see if it works.
Thanks,
Binh

That one surely has PMU emulation, but your guest does not see it. I blame
QEMU. Can you compile QEMU from git?

PMU support is not advertised to the guest which means that either
QEMU is broken or your host kernel does not have PMU kvm support. What is
your host kernel version?
I didn't know that the kernel was not compiled with virtualization
support as I was using a ready image from ubuntu website to install
the VM. In the long run, are you suggesting me to recompile the
kernel for the guest to make sure that it has virtualization
support?
I am surprised ubuntu kernel does not have virtualiztion support
compiled in. May be they have separate kernel for that, but I am not
ubuntu user so cannot tell.
