Copying VM Host Installation Package to the PXE Boot Server

You can install the host OS, tools, and the Junos virtual machines (VMs) on the devices with Routing Engines that support VM host by using the Preboot Execution Environment (PXE) boot method. This is one of the methods used for a fresh installation. A PXE boot prepares a client/server environment to boot devices by using a network interface that is independent of available data storage devices or installed operating systems. The image of the operating system is stored on a TFTP server.

To copy the installation packages to the PXE boot server:

  1. Copy the downloaded installation media to the /var/tmp directory in the PXE boot server.
  2. Log in to the PXE boot server and verify the installation file.
  3. Extract the junos-vmhost-install-net TAR file.
  4. Remove the previously installed files, if any, from the /tftpboot directory.
  5. Extract the network installation package.
  6. Rename or delete the previously installed root file system/scripts from the /var/install directory. Create a new /var/install directory.
  7. Extract the installation package.
  8. Set permissions for the files in the /var/install and /tftpboot directories.
  9. Exit the PXE boot server.
