Zig-based Hypervisor

zvisor's Issues

virtio-blk support

Cool project!

Please let me know when block devices become supported for larger application payloads than what fits an initrd.

What the Zig (large amounts of change required to compile)

I'm getting a build error:

$ zig build
/home/sfisher/.dotfiles/asdf/.asdf/installs/zig/0.11.0/lib/std/Build/Step/Compile.zig:616:21: error: deprecated; use std.Build.installArtifact
pub const install = @compileError("deprecated; use std.Build.installArtifact");
                    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    remaining reference traces hidden; use '-freference-trace' to see all reference traces

Which I've been able to get around by changing the build.zig file:

const std = @import("std");

pub fn build(b: *std.Build) !void {
    const target = b.standardTargetOptions(.{});
    const optimize = b.standardOptimizeOption(.{});
    const root_source_file = std.Build.FileSource.relative("src/main.zig");

    // zvisor executable
    const zvisor_step = b.step("zvisor", "Install zvisor executable");

    const zvisor = b.addExecutable(.{
        .name = "zvisor",
        .root_source_file = root_source_file,
        .target = target,
        .optimize = optimize,
    });
    zvisor.linkSystemLibrary("c");

    const zvisor_install = b.addInstallArtifact(zvisor, .{});
    zvisor_step.dependOn(&zvisor_install.step);
    b.default_step.dependOn(zvisor_step);

    // Tests
    const test_step = b.step("test", "Run tests");

    const test_exe = b.addTest(.{
        .root_source_file = root_source_file,
        .optimize = optimize,
        .target = target,
    });

    const test_run = b.addRunArtifact(test_exe);
    test_run.step.dependOn(zvisor_step);
    test_step.dependOn(&test_run.step);
    b.default_step.dependOn(test_step);
}

However, after this point, lots of things are... unique... zig fmt src/* fixes a few issues, but I'm unsure about others. Any help would be appreciated.
