When you install Windows Server 2008 R2 the default page file setting is ‘Automatically manage paging file size for all drives’. Hyper-V hosts are often loaded with a lot of RAM (96GB is not an exception). Because of the ‘Automatically manage paging file size for all drives’ setting your page file will be huge:

There is no reason for such a huge pagefile nor it has any advantage for the parent partition (paging will take place in the virtual machines).

So you can save some space on your hardrive by setting the page file setting to a fixed size:

In the various Hyper-V deployments that I’ve already done I’ve set the pagefile fixed to 6 GB and it works well! Even monitoring this setting with SCOM does not popup alerts Open-mouthed smile

There is one thing you need to keep in mind: when configuring the pagefile with a value lower than the physical memory, a full memorydump/crashdump file will be incomplete when the system crashes.
