ESXi Embedded Host Client

The ESXi Embedded Host Client is a native HTML and JavaScript application and is served directly from your ESXi host! It should perform much better than any of the existing solutions.

Please note that the Host Client cannot be used to manage vCenter.

We welcome any feedback and bug reports. You can post your feedback here on the VMware Labs site, in the community forums, or using the Host Client’s built-in Feedback tool under the Help menu.

Download the VIB here. If you are looking to automate installation of the latest VIB, we also provide a copy of the latest VIB here.

Known Issues

  • On hosts using ESXi 6.0 Update 1 or lower and ESXi 5.5 Patch 8 or lower which are assigned a VMware vSphere Hypervisor license (the free license from, all modification operations will fail silently. This issue has been resolved in ESXi 6.0 U2 and 5.5 Patch 8.
  • Hosts with ESXi 6.0 before Update 2 which have a sub-domain name with a combined cookie size of >8KB in-browser web console sessions may fail to initialize. A workaround is to clear cookies or run the host client in an incognito-type window, or alternatively, use the standalone VMware Remote Console application.
  • For ESXi 5.5 hosts, in-browser consoles are not supported. Please use VMware Remote Console (VMRD) to access guest VM consoles.
  • For ESXi 5.5 hosts before Update 2, you must ensure to append a trailing / (forward slash) to the URL after /ui. The URL must be https:///ui/

What’s missing?

The Embedded Host Client is currently undergoing development. We are working hard to bring the functionality level to that of the vSphere Client, but we’re not there yet. Here’s what we know is missing:

  • Resource pool management
  • Comprehensive performance chart UI with access to all performance counters
  • Exporting performance counter data to Excel/CSV
  • Multi-NIC vMotion configuration
  • Deploying VMs from a URL
  • Exporting VMs to an OVA

Offline Bundles

Offline bundles are packages that can be loaded into VMware Update Manager to facilitate easy installation of the Host Client onto a cluster of ESXi Hosts

VMware Remote Console VIBs

Installation of the VMRC VIBs is optional and intended to facilitate downloading VMRC in situations where access to is not possible. The VIBs are installed into the /locker partition of your host’s locally attached disk. This partition has limited space, and so care should be taken to ensure that sufficient space is available. Each VIB is roughly 20 MB in size.

Open source disclosure

We provide an open source disclosure package for the required packages.

A complete open source disclosure can be found in the About dialog of the Host Client.


The easiest way to install a VIB is to download it directly on the ESXi host. Alternatively, you can download it to your local machine and use scp to push it to your ESXi Host.

All installation techniques require you to enable SSH on your ESXi host, using DCUI or the vSphere web client. If your ESXi host has internet access, you can install directly from URL.

ssh root@ esxcli software vib install -v

where is the URL to the VIB from the Flings website or somewhere you have locally hosted it.

If the VIB installation completes successfully, you should now be able to navigate a web browser to https:///ui and the login page should be displayed.

If you have downloaded the VIB to your local machine, you will need to push it to ESXi using scp.

scp /path/to/downloaded/vib/esxui.vib root@:/tmp
ssh root@ esxcli software vib install -v /tmp/esxui.vib


ssh root@ esxcli software vib update -v

You may need to clear the cache in your browser to see the updated version.


To remove the ESXi embedded host client from your ESXi host, you can use esxcli.

ssh root@ esxcli software vib remove -n esx-ui

Note: The ESXi Embedded Host Client has been officially released for ESXi 5.5, ESXi 6.0 and ESXi 6.5. We continue to release Fling versions with the latest bug fixes and features.
