Selective Hardware/Software Memory Virtualization
Glossary of Virtualization Technologies Address-Space Compression: The challenges of protecting portions of the virtual-address space and supporting guest access to them.
Virtualization Based Security is a Windows 10 and Windows Server 2016 feature that enhances security by creating an isolated region of memory called a memory enclave, using the hypervisor capabilities of Windows. The VM must be presented with the same hardware as a bare metal server and the following need to be met in order to enable the feature:

With virtual memory, for example, computer software gains access to more memory than is physically installed, via the background swapping of data to disk storage. Similarly, virtualization techniques can be applied to other IT infrastructure layers – including networks, storage, laptop or server hardware, operating systems and applications. This blend of virtualization technologies – or

Virtualization provides value for many workloads, but its cost rises for workloads with poor memory access locality. This overhead comes from translation look aside buffer (TLB) misses where the hardware performs a 2D page walk (up to 24 memory references on x86-64) rather than a native TLB miss (up to only 4 memory references).
