CLI Reference

Overview

The xms CLI is a command-line client for the Xloud Migration Suite. It mirrors the Dashboard Migration panel: every action you can take in the UI is available as a CLI command, and every object you can inspect in the UI is available as a structured CLI response. Use the CLI when you want to script multi-wave campaigns, run migrations from CI, or integrate XMS with your own automation.

The CLI authenticates against the platform identity service with the same credentials you use for the Xloud Dashboard. Project scope is resolved from the authenticated token.

Global Options

These options apply to every subcommand.

Option	Description
`--os-cloud <name>`	Select a named cloud from your `clouds.yaml`
`--os-auth-url <url>`	Override the identity endpoint
`--os-project-name <name>`	Set the project scope
`--os-project-domain-name <name>`	Set the project domain
`--os-username <name>`	Authenticated user
`--os-password <password>`	Password (prefer `--password-stdin` or env vars)
`-f, --format <fmt>`	Output format: `table` (default), `json`, `yaml`, `csv`
`-q, --quiet`	Suppress non-essential output
`-v, --verbose`	Show request and response detail
`--no-color`	Disable ANSI colors in table output

Store credentials in clouds.yaml or environment variables (OS_*) and reference the cloud with --os-cloud. This keeps secrets out of shell history.

Migrations

Submit, monitor, and manage migration jobs.

xms migration submit

  --kind cold \
  --target-project infra \
  --flavor m1.large \
  --volume-type ssd \
  --availability-zone az-1 \
  --network-map 'VM Network=internal-net'

# Warm migration with a 1-hour incremental cadence
xms migration submit \
  --source prod-vcenter \
  --vm db-prod-01 \

Scripting Patterns

Wave Preflight and Submit

Run preflight on a wave file, then submit cold migrations for everything that passes:

SOURCE=prod-vcenter
WAVE=wave-1.txt

# Preflight the whole wave
xms preflight run --source $SOURCE --from-file $WAVE

# Submit cold migrations for Pass results
xms preflight list --source $SOURCE --filter 'verdict=pass' -f json \
  | jq -r '.[].vm' \
  | while read vm; do
      xms migration submit \
        --source $SOURCE \
        --vm "$vm" \
        --kind cold \
        --target-project infra \
        --flavor m1.large \
        --volume-type ssd \
        --network-map 'VM Network=internal-net'
    done

Watch a Running Campaign

Follow every job in the current project and print a live status table:

watch -n 10 'xms migration list --filter "status=running,status=syncing"'

Cutover After All Warm Jobs Reach Ready

Wait until every warm migration in a wave is Ready, then cut them all over in sequence:

xms migration list --filter 'kind=warm' -f json \
  | jq -r '.[] | select(.status == "ready") | .id' \
  | while read job_id; do
      xms migration cutover --job $job_id
    done

Exit Codes

The CLI exits with a non-zero code on failure so it can be used in shell pipelines and CI:

Exit Code	Meaning
`0`	Success
`1`	Generic error (bad flags, validation failure)
`2`	Authentication or authorization failure
`3`	Source or VM not found
`4`	Job failed or timed out while following
`5`	Network or transport error talking to XMS
