Sealing a Linux Template

Sealing a Linux Template

Templates that have been created for Linux virtual machines must be generalized (sealed) before use. This section describes how to seal a template before use. This ensures that machine-specific settings are not propagated through the template.

1. Login to the virtual machine to be used as a template and flag the system for re-configuration by running the following command as root:

   # touch /.unconfigured

2. Remove ssh host keys. Run:

   # rm -rf /etc/ssh/ssh_host_*

3. Shut down the virtual machine. Run:

   # poweroff

The Linux virtual machine has now been sealed, and can be used as a template for Linux virtual machines.

위의 방법대로 템플릿을 만들면 새로 VM구성시 네트웍등의 구성을 새로 할 수 있음
