E2E Regression

scripts/e2e.sh is a testbed lifecycle regression (modeled on cocoon’s), in two tiers.

[DUMMY] — file-level, no macOS boot

Runs on any x86 Linux/KVM host against a tiny throwaway qcow2 (no macOS boot):

• Image store (pull-less list/rm).
• vm create overlay-on-shared-base.
• --random-smbios serial/MAC uniqueness + MAC == ROM.
• snapshot/restore (qcow2-internal tag rollback).
• clone (CoW on the shared base + distinct identity + clone-of-clone backing).
• stop PID-reuse-safe teardown.
• --net bridge auto-TAP create + tap_owned + teardown-on-rm + user---tap preservation + negative paths.

Post-conditions assert no leaked TAPs/procs and backing-chain integrity. The --random-smbios rows need root + nbd + a real CM_OPENCORE; the --net rows need root + a test bridge (they SKIP, not FAIL, otherwise).

[REAL] — boots the golden image

Boots tahoe:26 from the store, passes the OpenCore picker over the HMP monitor, and asserts SSH-ready (sw_vers 26.x) + in-guest serial == injected. Testbed-only.

Running

sudo CM_BIN=./cocoon-macos CM_OPENCORE=.../OpenCore.qcow2 ./scripts/e2e.sh          # [DUMMY] (30 rows)
sudo CM_HOME=~/cm-demo CM_OPENCORE=... CM_OVMF_CODE=... CM_OVMF_VARS=... \
  ./scripts/e2e.sh --real-only

The [DUMMY] tier is the behavioral gate today’s CI structurally can’t give (CI is pure go test / vet / build — nothing opens /dev/kvm or mutates netlink); it belongs on a privileged self-hosted KVM runner. [REAL] stays a manual/nightly testbed run (~15 GB + cold boot).
