From d5f1a8a50905e847f8c88a9316fd878454dde2e4 Mon Sep 17 00:00:00 2001 From: robojerk Date: Wed, 10 Sep 2025 14:23:37 -0700 Subject: [PATCH] Add QEMU testing and real bootc binary integration - Added --test-with-qemu and --qemu-timeout options - Implemented QEMU testing functionality to validate disk images boot - Replaced placeholder bootc script with real binary download from registry - Added fallback to placeholder script if download fails - Updated todo.txt to reflect 90% completion status - Added test_example.sh to demonstrate new functionality Key improvements: - QEMU testing validates boot process with timeout and log analysis - Real bootc binary downloads from particle-os registry - Project status updated from 85% to 90% complete - Only remaining work: testing with real container images --- src/main.rs | 209 +++++++++++++++++++++++++++++++++++++++++++++++- test_example.sh | 35 ++++++++ todo.txt | 15 ++-- 3 files changed, 249 insertions(+), 10 deletions(-) create mode 100755 test_example.sh diff --git a/src/main.rs b/src/main.rs index 3146b26..c8f5530 100644 --- a/src/main.rs +++ b/src/main.rs @@ -99,6 +99,14 @@ struct Args { /// Cloud provider for cloud-specific optimizations #[arg(long)] cloud_provider: Option, + + /// Test the created disk image with QEMU + #[arg(long)] + test_with_qemu: bool, + + /// QEMU timeout in seconds for boot testing + #[arg(long, default_value_t = 30)] + qemu_timeout: u64, } #[derive(Debug, Clone, clap::ValueEnum)] @@ -169,6 +177,13 @@ fn main() -> Result<()> { info!("Successfully built bootc image at: {}", image_path.display());
