Radiance

Experimental KVM based VMM for aarch64 platform.

Defining characteristics:

• no external dependencies
• statically compiled (no libc or musl)
• no memory allocations after the VM start
• minimal memory overhead over requested VM memory size

Build:

    $ zig build -Doptimize=ReleaseFast -j4

Usage:

Usage:
        --config_path: type []const u8

Example:

radiance --config_path config.toml

Example config file:

[machine]
vcpus = 2
memory_mb = 128

[kernel]
path = "vmlinux-5.10"

[[drives]]
read_only = true
path = "ubuntu-22.04.ext4"

Linux kernel: To compile kernel use:

make -Image -j

The resulting kernel image will be at arch/arm64/boot/Image.
