I'm not sure what timestamps exactl you're using wi
Ok. so I will then shift to using system tap, Are the timestamps
generated for events compatible with the ftrace timestamps? so that I
can still merge the traces using TSC_OFFSET.
Thanks,

Hi,
I have setup the merging of traces from Guest QEMU and Host using the
TSC_OFFSET. So I would like to work with ftrace backend of QEMU. So
how can I add this option in libvirt tools to enable ftrace backends

I would have to

Hi,
I am able to get traces from Guest kernel + QEMU + Host kernel using the
qemu -trace evetns=/tmp/events option
My complete command line is:
/home/gnayan/QEMU-devel/qemu-ubuntu/qemu/x86_64-softmmu/qemu-system-x86_64
-trace events=/home/gnayan/qemu_events -drive
