Jaap Wesselius: One of the discussions when designing a Hyper-V server is about the pagefile settings.
The pagefile is used for:
* Supply Virtual Memory to the operating system (i.e. the parent partition). Traditional guidance states ~1.5x the amount of physical memory, although this doesn’t make sense anymore on a >64GB host;
* Crash dump purposes, but on a hosts with lots of memory (more than 64GB) do you want to have a full memory dump? Look at the number of hours this memory dump will take and you’re convinced that for 98% of all cases a kernel dump is sufficient.
Normally the parent partition uses around 2GB of memory (recommendation) so I usually recommend a manually managed pagefile of approximately 4 ~ 6 GB. Why not a system managed pagefile? Because it will grow to the amount of physical memory.
