Final answer:
The examples of Hardware-Assisted Virtualization (HAV) technologies from the options provided are VT-x and AMD-V, which both improve the performance of virtual machines on Intel and AMD processors, respectively.
Step-by-step explanation:
Hardware-Assisted Virtualization (HAV) technologies include a set of processor enhancements that improve the efficiency of virtualization solutions. Among the technologies listed, the two examples of Hardware-Assisted Virtualization technologies are:
VT-x is Intel's technology for virtualization on x86 platforms. It stands for Intel Virtualization Technology for x86 and is built into most of Intel's CPUs, providing hardware support to improve the performance of virtual machines.
AMD-V stands for AMD Virtualization and is an analogous technology developed by AMD. Like VT-x, AMD-V also enhances the performance of virtualized systems on AMD processors.
It is important to note that EPV is not a known standard technology in virtualization, Hyper-V is a software hypervisor created by Microsoft, and AMD Catalyst is a software driver suite for AMD's graphics cards, thus none of these are HAV technologies.
