Proxmox VE vzcfg Commands

The vzcfg command-line tool in Proxmox VE is used to configure and manage aspects of containers within Proxmox VE. It offers a more granular level of control compared to the higher-level pct tool.

Key vzcfg Commands:

  1. Create a Configuration File:

    • vzcfg create <container_id> <template>: Generates a configuration file (vz.conf) for a new container based on the specified template. Replace <container_id> with the desired ID and <template> with the template name.

  2. Modify Container Configuration:

    • vzcfg edit <container_id>: Opens the vz.conf file for the specified container in a text editor for manual modifications.

  3. Set Configuration Options:

    • vzcfg set <container_id> <option>=<value>: Sets a specific configuration option for the container. Replace <option> with the desired option name and <value> with the desired value. Example: vzcfg set 100 onboot=1 enables automatic startup for container 100.

  4. View Configuration Options:

    • vzcfg dump <container_id>: Displays the current configuration options for the specified container in a structured format.

  5. Validate Configuration:

    • vzcfg check <container_id>: Checks the syntax and validity of the container’s configuration file.

  6. Apply Configuration Changes:

    • vzcfg update <container_id>: Applies the changes made to the container’s configuration file.

Additional Options:

  • vzcfg help: Provides help information for vzcfg commands.
  • man vzcfg: Displays the man page for the vzcfg command with detailed explanations and examples.

Remember:

  • vzcfg directly modifies configuration files, so it’s important to understand the syntax and implications of the changes you make.
  • Use vzcfg with caution, as incorrect configurations can affect container functionality.
