A bit of context first : on Windows 2008 Standard x64 with 8Gb RAM, I have 5 VMs running which should take up 1664Mb RAM (3*256Mb+384Mb+512Mb). There is nothing else running on this server except the basic OS components (this not a Core installation). I know that each VM will use more RAM on the host than what has been configured in Hyper-V.

But when I run the task manager, it says 6.7Gb used ! If I sum up the RAM used by each process in the task manager (showing all users processes), I get to something around 1Gb...

So : how can I check how much RAM each VM is really using on the host (it does not seem to be available via task manager) ?

Note that I am aware of the fact that my problem could be unrelated to VM RAM usage, but I would still very much like to know how to do this.
