+@example
+@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.
