What is huawei-cloud-sms-host-migrator?

A host migration assistant for moving servers from a local data centre or another cloud to Huawei Cloud virtual machines through Server Migration Service (SMS). It supports file-level or block-level replication depending on the source system.

Use it to prepare source hosts, run compatibility checks, define target virtual machines, track replication, perform cutover synchronisation, and validate the migrated host.

Moving a server can fail because of incompatible operating systems, disk layouts, firmware, file systems, or network access. This add-on checks those conditions and helps coordinate the move.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00169	$0.06231
Opus 5.5	$0.00068	$0.02492
Sonnet 5.5	$0.00034	$0.01246
Haiku 4.5	$0.00017	$0.00623

Security

Grade B, and why

huawei-cloud-sms-host-migrator scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 29d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/test-cli-commands.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

- If `state: "unavailable"`, the agent is disconnected; guide the user to restart the agent on the source host (`sudo ./startup.sh` on Linux or restart `SMS-Agent` Windows service).

Huawei Cloud SMS Host Migrator

The Huawei Cloud SMS Host Migrator skill automates and guides the full lifecycle of host migration from on-premise IDCs or third-party clouds (Alibaba Cloud, Tencent Cloud, AWS) to Huawei Cloud ECS or Flexus X instances using the Huawei Cloud Server Migration Service (SMS).

Overview

The migration process supports file-level replication (MIGRATE_FILE) for Linux source hosts and block-level replication (MIGRATE_BLOCK) for Windows Server source hosts.

Key capabilities provided:

Guided Agent Deployment: Generate installation instructions for Linux and Windows Server source machines.
Pre-migration Compatibility Diagnostics: Automatic checks for OS version, firmware (BIOS/UEFI), disk partition table (MBR/GPT), file system, and required network ports.
Target Specification Modeling: Provision migration templates targeting Huawei Cloud standard ECS or cost-effective Flexus X instances.
Replication Orchestration: Track replication tasks, remaining time (remain_seconds), throttling limits, progress percentages, and subtask states.
Cutover and Validation: Execute incremental sync windows, detach migration drivers, and verify target host boot status.

Prerequisites

KooCLI (hcloud): Installed and authenticated with a valid profile (cn-north-4, ap-southeast-3, etc.).
- Follow instructions in references/cli-installation-guide.md.
Target Security Group Inbound Rules: The destination ECS security group must allow specific inbound ports strictly from the source server IP:
- Linux: Inbound TCP port 22 (secure rsync over SSH).
- Windows Server: Inbound TCP ports 22 (initialization), 8899 (control channel), and 8900 (block data streaming).
- Default Creation Behavior: By default, create a dedicated new security group populated strictly with these rules rather than reusing an existing group.
- Target Outbound Rules: Outbound TCP port 443 allowed to SMS API and Huawei Cloud services.
- Target Subnet Network ACL: Ensure associated subnet ACLs allow matching inbound ports and return ephemeral ports.
- Security Guardrail: Do not set source address to 0.0.0.0/0; restrict strictly to source server IP.
Source Server Network & Environment:
- Outbound TCP port 443 open to SMS control plane: sms.cn-north-4.myhuaweicloud.com (China Site) or sms.ap-southeast-3.myhuaweicloud.com (International Site - Singapore).
- Outbound TCP ports 22, 8899, 8900 open to target ECS (public EIP or private IP via VPN/Direct Connect).
- NTP Time Synchronization: Source system clock drift must be within 15 minutes of standard time.
- Dependencies: Linux requires rsync, tar, nohup, python; Windows requires PowerShell 3.0+ and VSS service.
- Disk Space: Linux root partition (/) ≥ 200 MB free space; Windows partitions ≥ 600 MB require ≥ 320 MB free space.
IAM Permissions: Sufficient permissions for SMS FullAccess, ECS CommonOperations, VPC Administrator, and EVS CommonOperations.
- See least-privilege definitions in references/iam-policies.md.
- See complete pre-migration checklist in references/pre-migration-checklist.md.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
