| kvm_stat - Report KVM kernel module event counters |
| kvm_stat prints counts of KVM kernel module trace events. These events signify |
| state transitions such as guest mode entry and exit. |
| This tool is useful for observing guest behavior from the host perspective. |
| Often conclusions about performance or buggy behavior can be drawn from the |
| The set of KVM kernel module trace events may be specific to the kernel version |
| or architecture. It is best to check the KVM kernel module source code for the |
