End-to-end now drives a real KVM guest through the full XMRig-shaped
phase schedule with the workload running INSIDE the guest. Telemetry is
host-side /proc/<qemu_pid>; the load is busybox `yes` (sustained CPU
saturation) and `dd if=/dev/urandom` (disk burst on infecting), driven
over the serial console at every phase transition. The plotted envelope
shows clean idle → armed → infecting (disk spike) → infected_running
(100% CPU plateau) → dormant → re-entry → final clean.
Components:
vm/launch_demo.sh now boots Alpine 3.21 nocloud-cloudinit
(Cirros 0.6.x's cirros-init blocks on the
EC2 metadata service for ~17 min before
falling through to NoCloud — abandoned).
Mounts a cidata ISO as a second drive.
tools/build_cidata.py pure-Python NoCloud ISO builder (pycdlib).
Sets root password and ssh_pwauth via
runcmd so we don't depend on a specific
cloud-init version's plain_text_passwd
handling.
tools/vm_serial.py serial-console client (stdlib socket).
Idempotent login (detects already-in-shell
state), sentinel-bracketed run() that
distinguishes shell output from the TTY
echo of input by requiring a leading
\r\n boundary on the marker.
tools/vm_load_controller.py in-guest load controller. set_phase()
dispatches the per-phase shell command
over the serial connection.
tools/run_real_vm_demo.py ties it all together: boot VM, wait for
cloud-init runcmd, log in, run the
EpisodeRunner with on_phase=controller,
shut down VM.
Deps: paramiko, pycdlib added.
docs/sources.md updated with Alpine cloud image (sha512 pinned), and
the new Python deps.
README leads with the tier-2 plot now (real VM, real workload). The
previous synthetic plot is moved below with explicit "host-side mimic,
not a VM" labelling. Tier-2 status flipped to ✅ in the tier table.
