tenclass / mvisor

A mini x86 hypervisor

MVisor: A mini x86 hypervisor

Goal

1. A minimal hypervisor based on KVM and x86 (replace QEMU)
2. A limited number of emulated devices (support plugins in later version)
3. Linux and Windows as guest VMs
4. VFIO (especially vGPU) and migration
5. Extremely stable and high performance
