vSphere 6.5 is available and the last update is accessible.

1.Before to start …

Installation of an ESXi is a simple tasks. But in order to gain support in production and to avoid any impact without any help from the editor , you must take care of others things :

vCenter can be a central point for different software solutions around :

  • backup tools
  • orchestration,automation tools or CMP
  • Authentification
  • Certificates Management
  • Others : SDN solutions, Nexus 1000v etc …

Of course hardware support is mandatory if you want to have a full fonctionnal solutions with full support.

VMware provides two quick elements to validate solutions  :

Hardware Compatibility Matrix : link

This part  provides information about hardware compatibility (servers, network card, storage array) both drivers and firmwares.

Vmware product interoperability :link

This second part provides all the elements for vmware product compatibility. You can have some elements with external database compatibility too for example, and other software products delivered by vmware (SRM compatibility with vSphere, vCloud Directoy compatibility with NSX etc …)

2.And now the preparation of the installation

Before anything, you have to prepare some kind of elements. The table below show some of them.

Don’t forget password management :

Use always some simple and free programs : keepass for example and keep the store on different places.

The basics

Parameter VALUE check
Server NAME example :
IDRAC/ILO Name example :
IP ADDRESS Server ESXi example :
VLAN ID “id vlan” (T = tagged,U = untagged)
NETMASK ESXi example :
GATEWAY ESXi example :
DOMAIN tech.jmlabs.local


Parameter VALUE check
IP VMOTION 01 example :
NETMASK VMOTION 01 example :
VLAN ID VMOTION 01 “id vlan” (T = tagged,U = untagged)
IP VMOTION 02 example :
NETMASK VMOTION 02 example :
VLAN ID VMOTION 02 “id vlan” (T = tagged,U = untagged)

iSCSI Storage if used


Parameter VALUE check
IP ISCSI 01 example :
NETMASK ISCSI 01 example :
VLAN ID ISCSI  01 “id vlan” (T = tagged,U = untagged)
IP ISCSI 02 example :
NETMASK ISCSI 02 example :
VLAN ID ISCSI 02 “id vlan” (T = tagged,U = untagged)

NFS Storage if used

Parameter VALUE check
IP NFS example :
NETMASK NFS example :


STD-VSWITCH-NN -> vswitch standard

PG-STD-VLAN -> Port Group vSwith Standard

DVS-VSWITCH-NN -> Distributed Virtual Switch

DVS-STD-VLAN -> Port Group Distributed Virtual Switch

3. Installation of an ESXi

Select the device to boot on.














Loading Modules ….




























Start the installation, touch “Enter”













Accept the EULA by clicking on “F11”














Select the target drive to install ESXi. It can be an usb key, flash card, local disk, san disk etc … .











(Optional : if you already have a ESXi installed,  you have to make one of the three choices …)












Select the keyboard layout












Define the password. In this case, to avoid any issue like kvm configured in qwerty or something else, I have a password that is validated as well as in AZERTY or QWERTY so I should recommand to do the same to avoid any issue.










Ask to your boss a new hardware if you have this message. Currently, I have an old server so it’s still working with version 6.5 but for the next version, it will not work.












Install it !









During the installation you can take a coffee and sometimes the reaction can be like that !


Resume :

You use the wrong disk in boot on san

You use the good disk but you forget to move the templates

There is a critical local copy of a vm that you didn’t want to loose and there is no backup

You forget the password you’ve just write




Enter reboot …













4. Minimal configuration

Press F2 to configure network correctly














Enter the password of the default account









Now you can configure the server and because I am using certificates generates with a pki, and to avoid reboot etc I will select first “Troubleshooting Options”














And enable ssh















And now I configure my TCP/IP stack, DNS and so on …










I apply the configuration and I currently didn’t disable IPv6 which needs a reboot to be valid.









I transfer my .cer and my .key to /etc/vmware/ssl













I make some command to place correctly the certificates.




Now I disable the IPv6 stack.











And then I reboot …
