In the previous versions of vSphere, AutoDeploy & Image builder were available via PowerCLI. With the latest release both have been added in vCenter and can be used from vCenter Web Client GUI. For the lab purpose I’ll be using ESXi-6.5 HPE Custom image and inject older NIC & HBA driver in the image to make it work on Gen7 hardware. To start using Image builder & AutoDeploy we’ll have to start the service & can change the startup type Re-login to web client for AutoDeploy plugin to be activate d and visible on Home page Import a software depot to start using the image builder Import offline bundle of VIBs which you want to inject in the custom image Now a create new Software Depot & create a
Reboot the VCSA Press ‘e’ to enter the GRUB screen Enter ‘rw init=/bin/bash/ ‘ next to $photon_cmdline to boot the appliance in single user mode Use passwd command to reset the password and reboot

One of the key components of VMware SDDC suite is NSX which is a network virtualization platform. VMware has been a leader in compute virtualization for over a decade now and with the introduction of NSX it has become a leader in Software defined networking product. VMware NSX paves the way for enterprises to rapidly deploy networking and security for any application, on any general purpose hardware, non-disruptively, by enabling the fundamental abstraction of networks from networking hardware – creating the virtual network. Through network virtualization, more simplified logical networking devices and services can be abstracted away from the complexities of physical network engineering, exp
