HowTo - Using KVM default tracing tool

1. Install trace-cmd 

The source can be found in the kvm source file home directory. 

2. Suppose you are interested in i/o events, type in:

$ sudo trace-cmd record -e '*io*' virsh 

You can start your virtual machine in virsh. 

3. Use kernelshark to read the record.

$ kernelshark
