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 and the location of the TFTP server.
4 The ESXi host contacts the TFTP server and requests the file that the DHCP server specified.
5 The TFTP server sends the network boot loader, and the ESXi host executes it. The initial boot loader
might load additional boot loader components from the TFTP server.
6 The boot loader searches for a configuration file on the TFTP server, downloads the kernel and other
ESXi components from the HTTP server or the TFTP server and boots the kernel on the ESXi host.
7 The installer runs interactively or using a kickstart script, as specified in the configuration file.
