   * Fix VM provisioning to honor `maxRam` from CloudStack payloads when
     generating Firecracker configs.
   * Update documentation with a full agent configuration reference table.
+  * Report memory size from discovered VM configs so the UI shows the

+  * Persist and expose network uplink information for each VM, and improve
