14.7.5. Displaying CPU Statistics
The
nodecpustats command displays statistical information about the specified CPU, if the CPU is given. If not, it will display the CPU status of the node. If a percent is specified, it will display the percentage of each type of CPU statistics that were recorded over an one (1) second interval.
This example shows no CPU specified:
$ virsh nodecpustats
user: 1056442260000000
system: 401675280000000
idle: 7549613380000000
iowait: 94593570000000
This example shows the statistical percentages for CPU number 2:
$ virsh nodecpustats 2 --percent
usage: 2.0%
user: 1.0%
system: 1.0%
idle: 98.0%
iowait: 0.0%
You can control the behavior of the rebooting guest virtual machine by modifying the
on_reboot element in the guest virtual machine's configuration file.
