This talk presents the virtualization capabilities offered by the RISC-V Hypervisor ISA extension (H extension) as well as other RISC-V base ISA capabilities important to a hypervisor. The current state of the ISA and the H extension is discussed, along with ways in which they differ from current Xen-supported ISAs (x86 and ARM) and the impact this may have on the Xen codebase. Furthermore, current challenges in the RISC-V ecosystem will be discussed as well as how they will be dealt with in Xen.
