Guest set RAM size versus host VPC2007 Working set / Private bytes ?

I have recently installed Windows 7 RC 32bit
as a guest on VirtualPC 2007 on my Vista Home Premium 64bit.

I have set for it 1 GB RAM.
But, at my surprise, when lookit at Process Explorer on Vista,
it shows both Working set and Private byte near to 64 MB.

Similarly, for my guest Windows 2000 Professional SP4,
with RAM set to 512 MB,
the mentioned settings are near 30 MB.

One would say VPC allocates only needed RAM,
but around 60-65 MB it seems for Windows 7 32
too nice to be true..., so dead ratio 1 : 2
W2k versus W7.

The best depends on how the best is defined.

Hmm well, the available system memory drops as I would expected,
so Process Explorer obviously does not show all allocated memory.

That reminds me some note from Avast antivirus developers,
that AVG antivirus just seems to use less memory than Avast,
allocating it by less noticable way.

Process explorer only shows the VPC app mem usage, not the VMs usage.

I have realized that.
But, is not a VM part of the VPC app ?

Not as far as memory usage goes, its not directly assigned to the .exe
file. Nnone of the VM programs report memory this way (VBox, VMware,
VPC, Virtual Server).
