Subject: [Intel-gfx] [PATCH v2] Add the new tool for create GVT-g Linux guest based on KVMGT
GVT-g (Intel® Graphics Virtualization Technology) is a full GPU virtualization solution with mediated pass-through support.
This tool is for create basic Linux guest based on KVMGT with VFIO framework, it including create vgpu, create guest, check IP address, destroy guest, remove vgpu,check dmesg log, etc functions.
v2: Treat this case as a free-standing tool, with detect & skip when it's not running on GVT-g capable platform or running without the required tools.
