To the utm authors

I'm the author of the open source hypervisor https://github.com/macos-fuse-t/scorpi-hv.
It's a fairly new project, but you should consider adding it as another backend or completely replacing qemu.
It's already (almost)on par with qemu feature wise but have many advantages over it:
1. It's small, fully modular and API driven
2. It can run Windows/Linux VMs and works on both macOS and Linux (host)
3. It implements virtio devices including virtio-gpu. The basic display driver for Windows is already available with full DirectX 12 support coming in a few months.
4. The UI (screen viewer) is separated from the hypervisor and works by connecting to the framebuffer shared memory.
5. It supports all major features such as file sharing, networking, snapshotting, etc..
It's still a work in progress but eventually it will become much better than qemu for the end user.
P.S. I was also an original author or the qemu hvf module.
