- kvm_stat(1)
- ===========
- NAME
- ----
- kvm_stat - Report KVM kernel module event counters
- SYNOPSIS
- --------
- [verse]
- 'kvm_stat' [OPTION]...
- DESCRIPTION
- -----------
- 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
- output.
- 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
- meaning of events.
