PXE Boot Method

During the Oracle Enterprise Linux or Oracle VM host BIOS boot sequence, the PXE agent in the HCA option ROM scans the network for a PXE server through a VNIC. The PXE server delivers the kernel boot image and the initrd file containing the host drivers to the Oracle Enterprise Linux or Oracle VM host. The boot image and the initrd file are delivered for booting initially by using the DHCP and then the TFTP.

The process of PXE boot configuration is as follows:

1. Move the host drivers and OS image to the PXE server.

2. Load the host drivers into the initrd file.

3. Create a server profile.

4. Configure a bootable VNIC.

5. Modify the PXE configuration file.

6. Set the HCA to first in the boot order.

7. Load the initrd file and the OS image into the Oracle Enterprise Linux or Oracle VM host.
