Move all network-dependent operations into dedicated init steps so transient failures (registry timeouts, Koji 503s, etc.) surface early and don't abort a 3-hour test run mid-way. Changes by area: ci.yml: - install-tests: split 'Integration tests' into two steps: 'Build images and test binaries' (build + cargo compile) and 'Integration tests' (actual test execution). Both cargo build invocations now precede any test run, so a network-induced cargo failure is immediately identifiable. - test-baseconfigs: add missing 'Fetch external dependencies (with retry)' step (just build-fetch) before building the container, making it consistent with test-integration and test-upgrade. - test-container-export: add 'Fetch external dependencies (with retry)' step; split ISO download into a separate 'Build container and fetch Anaconda ISO' step (just fetch-anaconda-iso) before the test step. Justfile: - Add fetch-anaconda-iso target: downloads the Anaconda boot ISO with --retry 5 --retry-delay 30 so transient CDN failures are retried. The existing test-container-export target now asserts the ISO exists rather than downloading it, making the network/test boundary explicit. - Add bib_image and lbi_switch_images variables for images that must be pre-pulled on the GHA host (with retry) and exposed inside test VMs via --bind-storage-ro virtiofs, rather than pulled live during tests. - Extend build-fetch to pull bib_image and lbi_switch_images with retry. - Extend copy-lbi-to-rootful to include bib_image and lbi_switch_images (needed by the install-tests job which copies to root's storage). hack/provision-fetch.sh + hack/packages.txt: - Add skopeo to packages.txt (needed for busybox OCI pre-fetch below). - At the end of the fetch stage, use skopeo to download busybox as an OCI layout at /usr/share/bootc-test/busybox-oci. This runs within the network-allowed fetch layer so the busybox image is baked into the test container image and available to the test VM without a registry pull. tmt/tests/booted/readonly/030-test-composefs.nu: - Replace 'docker://busybox' pull with 'oci:/usr/share/bootc-test/ busybox-oci', using the pre-fetched OCI layout from provision-fetch.sh. tmt/tests/booted/test-bib-build.nu + tmt/plans/integration.fmf: - Add 'try_bind_storage: true' to the test's extra: block so xtask passes --bind-storage-ro to bcvk for plan-33. The BIB image (quay.io/centos-bootc/bootc-image-builder:latest) is pre-pulled on the GHA host and exposed via the virtiofs additionalimagestore, so 'podman run ... ' inside the VM finds it locally. tmt/tests/booted/test-logically-bound-switch.nu + tmt/plans/integration.fmf: - Add 'try_bind_storage: true' to the test's extra: block (plan-21). - In initial_setup, call 'bootc image pull-from-default-storage' for each bound image (ubi9/ubi-minimal:9.4, ubi9/ubi-minimal:9.3, alpine:latest) before building the derived container. These images are pre-pulled on the GHA host and visible inside the VM via additionalimagestore; pull-from-default-storage moves them into bootc's own storage so 'bootc switch' finds them there without a registry pull. tmt/plans/integration.fmf (Packit/OSCI path): - In the order-98 shell prepare step, copy hack/packit-reboot.yml to /tmp/packit-reboot.yml after extraction from the src.rpm. - Change the order-99 Ansible playbook reference from a live GitHub URL to /tmp/packit-reboot.yml, eliminating the live github.com fetch during Packit gating runs.

Block outbound internet from tmt test VMs by passing --restrict-network (bcvk's new QEMU slirp restrict=on flag) unconditionally to every plan's bcvk libvirt run call. This prevents mid-run registry pulls from causing spurious failures in 3-hour test runs. The inbound SSH port-forward used by tmt to reach the VM is unaffected. All container images and binaries needed by tests must be pre-fetched in the build/fetch phase before VMs are launched. Assisted-by: OpenCode (claude-opus-4-5-20251101)
…alpine registry.access.redhat.com is not reachable through the sandbox proxy. Substitute docker.io/library/alpine at equivalent tags as a pullable stand-in for the LBI and LBI-switch test images. The LBI tests only verify that the named images are present in bootc storage after boot - they do not execute anything from the images - so any pullable OCI image is a valid substitute for local testing.
