I have a question about running exchange on the hyper-v host. Store.exe is designed to use all but 2GB of memory when available. I am wondering if this includes memory allocation for hyper-v guests? I have 16gb physical ram On server. 6GB dedicated to vms, and exchange is running 8GB. The whole server is using 15.8GB and crashing often. Is it missing the vm-dedicated memory and using all the ram?
