[Qemu-devel] Trace Guest and Host

[Gadre Nayan]

Hi everyone,

I wanted to setup a ftrace based mechanism to understand flows within
the guest and host simultaneously.
Are there mechanisms available to get traces from guest and host and
then collate them to get a merged trace which helps to understand
exact flow of guest with host ? OR
generate a trace file which by default combines the traces from
running guest and host.

How can I setup such an environment, what qemu options can I specify
for this to work.

Thanks
