The first two patches are fixes whereas the second two patches make nested virtualization performance better on for QEMU RISC-V. These patches can also be found in riscv_nested_fixes_v1 branch at: https://github.com/avpatel/qemu.git The RISC-V nested virtualization was tested on QEMU RISC-V using Xvisor RISC-V which has required hypervisor support to run another hypervisor as Guest/VM.
