5.2. Chainbooting virtual machines

1. Virtual machine starts
2. iPXE retrieves the network credentials using DHCP
3. iPXE retrieves the HTTP address using DHCP
4. iPXE chainloads the iPXE template from the template Capsule
5. iPXE loads the kernel and initial RAM disk of the installer

Procedure

1. Copy a boot file to the TFTP directory on your Satellite Server:

   • For EFI systems, copy the ipxe.efi file:

     # cp /usr/share/ipxe/ipxe.efi /var/lib/tftpboot/

     Copy to Clipboard Toggle word wrap

   • For BIOS systems, copy the undionly.kpxe file:

     # cp /usr/share/ipxe/undionly.kpxe /var/lib/tftpboot/undionly.0

     Copy to Clipboard Toggle word wrap
2. In the Satellite web UI, navigate to Hosts > Provisioning Templates, enter Kickstart default iPXE and click Search.
3. Optional: If you want to change the template, click Clone, enter a unique name, and click Submit.
4. Click the name of the template you want to use.
5. If you clone the template, you can make changes you require on the Template tab.
6. Click the Association tab, and select the operating systems that your host uses.
7. Click the Locations tab, and add the location where the host resides.
8. Click the Organizations tab, and add the organization that the host belongs to.
9. Click Submit to save the changes.
10. Navigate to Hosts > Operating systems and select the operating system of your host.
11. Click the Templates tab.
12. From the iPXE Template list, select the template you want to use.
13. Click Submit to save the changes.
14. Navigate to Hosts > All Hosts.
15. In the Hosts page, select the host that you want to use.
16. Select the Templates tab.
17. From the iPXE template list, select Review to verify that the Kickstart default iPXE template is the correct template.

18. To use the iPXE bootstrapping feature for Satellite, configure the dhcpd.conf file as follows:

    if exists user-class and option user-class = "iPXE" {
      filename "http://satellite.example.com/unattended/iPXE?bootstrap=1";
    } elsif option architecture = 00:06 {
      filename "ipxe.efi";
    } elsif option architecture = 00:07 {
      filename "ipxe.efi";
    } elsif option architecture = 00:09 {
      filename "ipxe.efi";
    } else {
      filename "undionly.0";
    }

    If you use an isolated network, use a Capsule Server URL with TCP port 8000, instead of the URL of Satellite Server.

    注記

    Use http://satellite.example.com/unattended/iPXE?bootstrap=1 when Capsule HTTP endpoint is disabled (installer option --foreman-proxy-http false). Template Capsule plug-in has the default value 8000 when enabled and can be changed with --foreman-proxy-http-port installer option. In that case, use http://capsule.example.com:8000. You must update the /etc/dhcp/dhcpd.conf file after every upgrade.
