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

top - 17:22:04 up 22:37, 1 user, load average: 72.55, 73.18, 66.84 Tasks: 140 total, 1 running, 139 sleeping, 0 stopped, 0 zombie %Cpu(s): 98.1 us, 1.6 sy, 0.0 ni, 0.0 id, 0.0 wa, 0.0 hi, 0.3 si, 0.0 st KiB Mem : 16266748 total, 13817608 free, 1354756 used, 1094384 buff/cache KiB Swap: 8257532 total, 8257532 free, 0 used. 14582984 avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 13742 mysql 20 0 2748260 864628 9448 S 399.7 5.3 3434:55 mysqld 18981 root 20 0 162032 2320 1596 R 0.7 0.0 0:00.07 top 5212 root 20 0 126284 1704 1068 S 0.3 0.0 0:01.41 crond

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.
