Hi
I am novice to Vtune and trying to learn as much as I can but I am stuck with few warnings..I hope I can get through with your help.
I have been trying to use the vtune for kernel level analysis in virtualized environment with kvm and qemu. Host os : fedora 20, 3.15.6 Guest os : fedora 18, 3.11
I have installed the following packages on the host
kernel-debuginfo-3.15.6-200.fc20.x86_64
kernel-debuginfo-common-x86_64-3.15.6-200.fc20.x86_64
I am not able to drill down the kvm_intel functions and the warning shows that could not find the file kvm_intel.ko.
Could you please suggest me if I have to enable any flags for kvm or the path directories for the modules and debugging symbols.
binary/symbol paths: /usr/src/debug/kernel-3.15.fc20/`uname -r`; /usr/src/kernels/linux-3.15.6/ ( vmlinux) ; /usr/lib/debug/lib/modules/`uname -r`
source : /usr/src/kernel/kernel-3.15.fc20/`uname -r`; /usr/sbin; /usr/lib/modules/`uname -r`/source.
Please find the attachment of the warning log.
Thank you,
Monica.

Hi Peter,
Thanks for your prompt reply.But i am still unclear with this.
It does not state that Hardware Event-based Sampling is not supported on this operating system. I could do the advanced hotspot analysis but with some warnings like cannot find the kvm_intel.ko file . I have given the direct path in the search directories.
Please help me.
Thank you,
Moica.

I'm not sure if kvm_intel.ko is an existing module, you worked on KVM. Using PMU hardware event-based sampling (e.g. advanced-hotspots) is not encouraged), please "hotspots" instead, or you work on Linux operation system installed in none virtual machine environment.
