Two days ago I secure-erased my SSD and installed ESXi 6.7. I was previously running ESXi 6.5 on the same hardware, but multiple issues led me to do a fresh install.
I have installed a single VM. The VM appears to be running fine, and includes VMWare tools. It shows an average and maximum CPU usage of 1.86% and 21.78%, respectively, which seems reasonable under the circumstances.
The host shows average and maximum package0 CPU usage of 51.65% and 46.08% respectively. Yes, it's reporting a higher average than maximum; just eyeballiing the graph I would say 40% is a better estimate for average. All eight cores are showing steady activity, with the lowest average of the eight being 14.66% over the last hour, which is by itself higher than I would expect based on the reported usage of the single VM.
So my first question is why CPU usage is so high on the host with only one VM installed, and that VM showing comparatively much less CPU usage. I tried running esxtop on the host in an ssh session but the output was an unreadable and unending stream of text; it looked nothing like the table I'm used to seeing when I run top on other machines.
My second question is why esxtop is unusable on this platform. Is it a known issue in 6.7 or have I buggered something up already?
