| =========== | |
| 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. | |
