Apple Hypervisor

Xvisor® is an open-source type-1 hypervisor, which aims at providing a monolithic, light-weight, portable, and flexible virtualization solution. It provides a high performance and low memory foot print virtualization solution for ARMv5, ARMv6, ARMv7a, ARMv7a-ve, ARMv8a, x86_64, RISC-V and other CPU architectures. In comparison to other ARM hypervisors, it is one of the few hypervisors providing support for ARM CPUs which do not have ARM virtualization extensions. In RISC-V world, it is world first Type-1 RISC-V hypervisor. The Xvisor source code is highly portable and can be easily ported to most general-purpose 32-bit or 64-bit architectures as long as they have a paged memory management unit (PMMU) and a port of the GNU C compiler (GCC). Xvisor primarily supports Full virtualization hence, supports a wide range of unmodified Guest operating systems. Paravirtualization is optional for Xvisor and will be supported in an architecture independent manner (such as VirtIO PCI/MMIO devices).
