Recreate VM Skill

Recreate a VM from its existing machine configuration. This destroys current disks and creates fresh ones.

Instructions

Step 1: Get VM Name

Run just list-machines to show existing machine configs. Ask which VM to recreate.

Step 2: Confirm Recreation

IMPORTANT: Warn the user clearly:

  • •If the VM currently exists, it will be stopped and its disks deleted
  • •All data in /var and /home will be PERMANENTLY LOST
  • •Fresh disks will be created using the machine's profile
  • •The machine config (identity, SSH keys, etc.) will be preserved

Ask for explicit confirmation.

Step 3: Gather Options (Optional)

Ask if they want to customize:

  1. •

    Var Size - Size of /var partition (default: 30G). Offer choices:

    • •30 (default)
    • •50
    • •100
    • •Or type a custom value
  2. •

    Network - Network configuration (optional, uses existing config if not specified)

Step 4: Recreate

Run:

bash
yes | just recreate {NAME} {VAR_SIZE}

Or with network:

bash
yes | just recreate {NAME} {VAR_SIZE} {NETWORK}

The yes | is required to bypass the interactive confirmation prompt.

For var_size, append G to the number (e.g., 30G, 50G).

Step 5: Report Results

Confirm the VM was recreated and is running. Provide:

  • •How to check status: just status {NAME}
  • •How to SSH into it: just ssh {NAME} or just ssh admin@{NAME}
