-@c man begin SYNOPSIS
-usage: kvm_stat [OPTION]...
-@c man end
-@end example
-
-@c man begin 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.
-
-Note that trace events are counted globally across all running guests.
