Tracing kvm: kvm_entry and kvm_exit

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello everyone,
I am tracing kvm using perf and I am analyzing the sequences of kvm_entry and
kvm_exit tracepoints.
I noticed that during the boot process of a VM, there are a lot more (2 to 3 as
many times) kvm_entry event than there are kvm_exit. I tried looking around but
didn't find anything that explains this. Is this missing instrumentation? Or
what other path does kvm take that doesn't generate a kvm_exit event?

Thank you.
