Top command output for Virtual or Physical Machine [Resolved]

Does top output display information particular to the VM I am in, or the entire physical machine?

So here you see CPU usage at 98% - which is insane.

Is this for the VM or the iron?

Top will show utilization of the OS. I think your vm using 4 CPUS, and mysql running 399% cpu usage, it means 98% of total CPU.
