The data on all the cluster nodes can be read and written at the … [Read more...]

What is Hardware-Assisted Virtualization

Hardware Assisted Virtualization is also known as native virtualization. This is an approach to full virtualization in extended condition, wherein the processor provides the architectural support to facilitate the construction and the hypervisor forward calls of different guest operating system directly to the physical hardware, increasing the overall performance of the system. Xen hypervisor, … [Read more...]
