More polish on the UI

Great! Can we add a % after the 99.9. We should also add this for the Percent in the host virtual memory. Percent may not be clear as to what it means - I think we mean percent used?

Also, the HOST CPU section maybe should show cpu_count as the percentage I believe is spread across all cores so it's a bit hard to understand 8.8 percent for the host and 99.9 for the process. I am not sure if we want logical or not here. I suspect the default of logical=True is what we mean.

@mlucool Do you see any other needed changes?

No this is good
