Hello,

Class VM has 4 memory metrics:
1) memory/dynamic max (RW)
2) memory/dynamic min (RW)
3) memory/static min
4) memory/static max
5) memory/actual (Guest’s actual usage)

Questions:
1) What is dynamic memory? Is the "memory/dynamic max" a configuration parameter that you set imposing a limit on the maximum amount of memory a guest may use at runtime? In that case, what does "memory/dynamic min" mean?

2) What does "memory/actual" pertain to? A guests usage of the real, physical memory available on the box or its usage of the total memory (which could be more than the physical available) that has been allocated to it?
