VT-x is not a RISC-V feature, it is a feature of x86 cpus, which is definitely not deprecated. VT-x is (as far as I know) the technology that allows acceptable speed virtualization of virtual machines, which is the backbone of cloud computing. RISC-V H extension is not applicable to intel CPUs even if it provides features that solve similar problems (ie it cannot possibly be the replacement). https://en.wikipedia.org/wiki/X86_virtualization#Intel-VT-x https://en.wikipedia.org/wiki/X86_virtualization#Intel-VT-x
