If I'm understanding your question correctly, you want to know how RAM is allocated between the Host and Guest o/s's?

If so, the RAM is not allocated to the guest until you actually start the VM. As a general rule, NEVER allocate more than half of your physical memory to a VM and only a 1/4 if you plan on opening more than one VM at a time. Any more than that could possibly cause errors in the Host o/s and if it freezes, so goes the VM..

Mmm... Try allocating ~768MB to ~1 GB if you have 2+, that seems to be the sweet spot here. If you are rolling in RAM (5+ GB, go ahead and just drop 1.5 GB (the max) on Parallels.
 
Thanks so i have the whole of my ram until i start the VM so it allocates between the host and the guest. rigth?? so if i have 1gb of RAM i should give 256 to parallels and the rest for mac?? or i just dont have enougth RAM to run parallels the correct way??
 
Yes, you have all of your RAM until Parallels begins to run. Try giving ~ 512 MB of RAM to Parallels and see how things work. If they do not work to your satisfaction, tweak the settings, if they still do not work, consider getting more RAM.
