I have a 2012 R2 server hosting 2 Hyper-V servers that I have converted from VMWare. The host has 64GB, each guest had 16GB in VMWare but I was reading some best practices on Hyper-V and the dynamic RAM option was suggested as the way to go. The problem I am having is the RAM is not increasing as needed. When I log in and look at the Task Manager on the guest it shows 90% memory used and 16GB but the Hyper-V Manager shows around 4 or 6 GB is being allocated to that guest. It appears that something is not interfacing correctly. I updated the integration services seeing that was a common cause but it is still not functioning properly. For instance it is after hours and the RAM shows 97% used. There is no malware on the guest or host and all the processes are legit for a Terminal Server to be running. Any suggestions on what to do next?
