Hosted macOS runners run without nested virtualization: kern .hv_support is 0 and no binary can boot a VM there, entitlement or not. The macos job keeps the full compile gate and asserts the probe reports the known HVF absence with a working engine load, so any other regression still fails; the boot e2e stays on Linux and real Macs.
ecrou
a small microVM runtime based on libkrun
Try ecrou in the terminal
Installation
Linux (strictly confined snap, KVM required):
sudo snap install ecrou
sudo snap connect ecrou:kvm
macOS (Apple Silicon, Homebrew):
brew trust --tap libkrun/krun
brew install vhaudiquet/ecrou/ecrou
Usage
$ ecrou run -it ubuntu
root@ecrou-vm-m2glhl:/#
Embed ecrou into your project
ecrou is both a library and a tiny CLI frontend around it. The library is embeddable into any project, allowing to use microVMs easily.
Rust
ecrou is a Rust library, which can just be called:
use ecrou::vm::RunOptions;
use ecrou::NoProgress;
fn main() -> ecrou::Result<std::process::ExitCode> {
let code = ecrou::vm::run(
&RunOptions {
image: "ubuntu:resolute".into(),
command: vec!["uname".into(), "-a".into()],
..RunOptions::default()
},
&NoProgress,
)?;
Ok(std::process::ExitCode::from(code.clamp(0, 255) as u8))
}
