The interaction between the ESXi host and other servers proceeds as follows:
1 The user boots the target ESXi host.
2 The target ESXi host makes a DHCP request.
3 The DHCP server responds with the IP information, the location of the TFTP or HTTP server,
and the filename or URL of the initial network boot loader.
4 The ESXi host contacts the TFTP or HTTP server and requests the filename or URL that the
DHCP server specified.
5 The TFTP or HTTP server sends the network boot loader, and the ESXi host runs it. The initial
boot loader might load additional boot loader components from the server.
6 The boot loader searches for a configuration file on the TFTP or HTTP server, downloads the
kernel and other ESXi components as specified in the configuration file, and boots the kernel
on the ESXi host.
7 The installer runs interactively or using a kickstart script, as specified in the configuration file.
