KVM statistics
kvmstat |
[interval [count]] |
kvmstat
reports the activity of running
KVM virtual machines and their exit activity, injected interrupts,
emulations, and more, on a per virtual CPU basis.
kvmstat
should be used when trying to get
a rough sense of guest activity from the hypervisor's perspective, and
allows one to understand from a low-level perspective, what kind of activity
is going on inside of the virtual machine. In addition,
kvmstat
is useful for diagnosing reports of
pathological or faulty behavior inside of guests. While there is no expected
range of values for the fields displayed as that varies with the use of
virtual machines, if all of the virtual CPUs for a given virtual machine are
consistently zero, then that may indicate that a problem has occurred, for
example, a panic inside of the guest or a bug in the hypervisor.
If no operands are specified, then kvmstat
will display statistics every second until the program is terminated.
Every interval
