available physical memory lower than total

This article will focus on how this dynamic process affects what you see from the both the hypervisor and virtual machine’s perspective. This means that from the virtual machine’s perspective, it will have different amounts of RAM depending on the workload. Microsoft Hyper-V’s approach is to let the virtual machine and hypervisor communicate with each other, so that the RAM can be continually adjusted based on the virtual machine’s requirements. The two major hypervisors (VMWare and Hyper-V) have different ways of dynamically allocating more or less physical RAM to the virtual machines running on top of them.

Running resource intensive applications on a virtual machine is a great way to ensure they do not consume more compute resource than is necessary, and the same physical machine can be used to run multiple discrete workloads.Ī great example of this is generating reports in TMG Reporter, Sophos Reporter or WebSpy Vantage. The reporting process will increase the virtual machine’s RAM and CPU requirements, but once the reporting workload is complete, the actual requirement drops back down again.
