Hyper-V virtual machine Ram usage

I have a Hyper-V server hosting about 8 Virtual Win 7 machines.
The 7 machines have been running fine for months but I want to allocate ram efficiently so how do I find out how much each virtual PC is using so I can reallocate the ram?
Thanks.

If your Hyper-V server is not R2 SP1, you need to take this information from the virtual machines themselves. If you have R2 SP1 or you are willing to upgrade to SP1, there is an interesting feature called dynamic memory allocation: http://technet.microsoft.com/en-us/library/ff817651%28WS.10%29.aspx

As stated, you need Hyper-V Server 2008 R2 with Service Pack 1.  Then you need to configure the RAM on each Virtual Machine to use Dynamic Memory allocation - you set a minimum and a maximum.  Once selected, the Hyper-V manager should indicate how much RAM is assigned and how much the VM is requesting/using.

SP1 adds a feature called "Thin Provisioning" of RAM.  It allows you to:
 1-  Give your VMs more RAM than you have in your physical server
 2-  Set a minimum startup RAM
 3-  Set a maximum RAM that the VM can grow to
 4-  Set priorities:  Some VMs can have a greater priority on RAM (important VMs) and others a lower (test and development)
