I will not provide support for the information herein. If you do not understand something, figure it out on your own. If you need help figuring it out, use Google to solve your problems. Introduction Once the VMware ESXi hypervisor has been installed on physical hardware, you must perform the initial configuration. This tutorial will cover how to setup the management network, as well as provide the hypervisor internet connectivity which is required to download the vSphere management utility for remote management. The IP address you assign the ESXi hypervisor IS NOT used to connect to virtual machines. Changing this address will not affect virtual machine behavior. This is the most important concept to remember when working with the ESXi hypervisor and the virtual machines installed on top of it. Virtual machine addresses do not have to be on the same subnet as the management IP address. Best practice implies that the management IP address should be on a different network than virtual machines. The management IP address should be changed as little as possible. It is highly recommended that you DO NOT, UNDER ANY CIRCUMSTANCES, assign the ESXi hypervisor a dynamically allocated address (DHCP address). After assigning the ESXi hypervisor a static IP address, you may need to assign your workstation a static IP address on the same subnet in order to connect to the hypervisor and manage it remotely. When assigning a VLAN to the management network, it is imperative that you complete switch configuration, regarding VLAN configuration, BEFORE you assign a VLAN to the management network. If you have not completed your VLAN switch configuration, you will lose connectivity through the vSphere Client. To ease the setup process it is better to perform the VLAN configuration on your switches, and then assign the management VLAN through the physical console of the server running VMware ESXi. In order to download the VMware vSphere Client, your physical ESXi server must have internet connectivity. You must have your routing infrastructure in place, and have the IP settings of your physical ESXi server correctly configured for this to happen.

If you have multiple network adapters, you will see them on this screen. Press Enter when you are done selecting network adapters for the management network. NOTES: A common error is to assign all of the network adapters to the management network. DO NOT DO THIS. If you have multiple network adapters in an ESXi physical server, you can assign adapters not assigned to the management network to virtual switches. One network adapter is sufficient to manage an ESXi hypervisor. If you wish to add redundancy, a second network adapter is all that is needed. If you assign multiple network adapters to the management network, you will see them connected to the management port group on vSwitch0. They will not be available to assign to virtual switches (networks). Depending on how many physical NICs you have installed in the physical server, this screen may be substantially different.

If you have not completed your VLAN switch configuration, you will lose connectivity through the vSphere Client.

This address should be changed as little as possible. This IP address does not, and it is recommended that it IS NOT, need to be on the same IP subnet as virtual machine traffic.

Enter your networks primary DNS server, Alternate DNS server, and a hostname. If the DNS server of your network will be hosted by ESXi, you can use Google's public DNS servers located at 8.8.8.8 and 8.8.4.4. Press Enter when you are finished. NOTES: You are not required to set a hostname. If you have an existing DNS infrastructure, setting a hostname may be beneficial to providing future connectivity to the ESXi hypervisor.
