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. OPTIONS ------- -1:: --once:: --batch:: run in batch mode for one second -l:: --log:: run in logging mode (like vmstat) -t:: --tracepoints:: retrieve statistics from tracepoints -d:: --debugfs:: retrieve statistics from debugfs -p:: --pid=:: limit statistics to one virtual machine (pid) -f:: --fields=:: fields to display (regex) -h:: --help:: show help message SEE ALSO -------- 'perf'(1), 'trace-cmd'(1) AUTHOR ------ Stefan Hajnoczi
