Hello,

i just tested the memory hot add to a vm. This vm had 2048 MB. I set
the new memory to 2662 MB.
I logged into the vm and i've seen that hasn't been any memory change,
even if i said to the manager to apply memory expansion immediately.

Memory shown by free -m is 1772 MB.

Looking around i've found that that value was set in the option called
"Physical Memory guaranteed".

I tried setting this parameter to an higher value, but is still
showing 1772, even if it says that "Memory" parameter will be changed
immediately and minAllocatedMemory is changed at next boot.

What is the right workflow to hot increase the ram of a vm?
