ESXi Embedded Host Client Fling

Over the years it has always be quite a pain to manage an ESXi host standalone. You would either need to have installed the C# client or know your ESXCLI commands to do anything. As VMware is moving away from using the C# client you would most likely need to know your command lines to perform actions on the ESXi host.

Recently released on VMware’s Fling website is “ESXi Embedded Host Client” which I think will overcome the above problem.

So what is “ESXi Embedded Host Client” you may ask?

It’s a small client software which is installed on the ESXi host for you to get a GUI interface by using a web browser.  It looks just like the web client for vCenter but is purely for just managing an ESXi host. You may wonder why would I need this as I could just use the web client and manage it.

Well I have been through times where I had my ESXi host disconnected from vCenter and I need to SSH to the host or use C# client to access the host to perform some tasks. With this new fling all I would need is a web browser and I can get to my ESXi host... how cool is that?

At the moment the product is still in development stages so there are limited feature for you to use but it is worth deploying to your lab to try it out. It is really just 6-7 easy steps and no reboot of the host is required....


The software will only work on ESXi 6.0 and 5.5u3 onwards and you would need a browser which has java script and cookies enabled.

Install Methods:

There are two methods to install the VIB onto the ESXi host.

ESXi host which has Internet access

1) Use your favourite SSH client software to connect to the host, I will be using Putty
2) Run the following command to install the VIB: "esxcli software vib install -v" (URL subject to change)
If the URL has changed for whatever reason go to to Right click "Download" button and select "Copy link address". The address would be copied to your windows clipboard so that you can paste it in notepad, putty etc.

3) If the VIB was installed successfully you should see the screen below
4) In your web browser navigator to URL https://<ESXi-Host-IP/ui and enter your credentials to log on

ESXi host without Internet access

1) Go to and tick box "I have read and agree to the Technical Preview Agreement. I also understand that Flings are experimental and should not be run on production systems." Now you can click the "Download" button to download the VIB.

2)  Once you have downloaded the file upload the VIB to either a shared datastore the host can see or the local datastore of the ESXi host. I have documented the steps below of me uploading to a ESXi host using WinSCP
  • Using WinSCP launch the program and enter the details of your ESXi host IP, username, password then click "Login".
  • Once connected navigate to the directory where you would like to upload the VIB. I have uploaded to "tmp" directory and remember to make a note of the VIB name and disconnect your WinSCP session from the host

3) Use your favourite SSH client to connect to the host. ( I will be using Putty)
4)Run the following command to install the VIB: "esxcli software vib install -v <location of the VIB>" so for me the command was "esxcli software vib install -v /tmp/esxui-signed.vib"

5) If the VIB was installed successfully you should see the screen below
6) In your web browser navigate to URL https://<ESXi-Host-IP>/ui and enter your credentials to log on

As you can see from the screen shot below the amount of information that you have presented to you in a single panel of glass is really good and now you can also use your Mac to access these. There are limited features available to be used such as:
  • VM operations such as Power off, on, reset, suspend
  • Creating a new VM, from scratch or from OVF/OVA (Limited OVA support)
  • Displaying summaries, events, tasks, performance monitoring, notifications/alerts
  • Console to VMs
  • Host services such as maintenance mode, reboot, advance settings, security & users
  • Configure host networking and storage 

Removing the VIB
1) SSH to the ESXi host and run the following command "esxcli software vib remove -n esxui"

2) You should see the following message if it has been successful and using your browser going to URL https://<ESXi-Host-IP>/ui should give you a blank page

As you can see it is really quite simple to install and try out this really powerful tool. So give it a go and provide some feedback so that we can get a better host client software going forward from VMware.

Rolling back a version of ESXi

There is an option in VMware where after you have performed an major upgrade of ESXi you can roll back to your previous version. The benefit of this is that you would not need to reinstall your ESXi and its configuration if you had issues with the new software. I had to do this on one occassion in my lab where I upgraded from 6.5 to 6.7 and my VMs would not run because the CPU was not supported in 6.7. Please remember if you are using ISO method to upgrade ESXi please ensure you select "Upgrade ESXi, preserve VMFS datastore". Selecting "Install ESXi, preserve VMFS datastore" does not mean preserving datastore means retaining ESXi as it will still do a clean install of ESXi. This method does not work for vSphere 7.0 as there are changes to the partitions on the boot device. Below are the steps to roll back to a previous version which is quite straight forward. As always perform an backup of your host configuration before you upgrade or rollback ( KB2042141 ). I have

Configuring ESXi 6 host to send logs to Syslog Server

In my previous post I talked about configuring VMware Syslog server for Windows which is installed and enabled by default on installation of vCenter 6 for Windows. I will now describe the basic configuration that is required on an ESXi 6 host to be able to send logs out to a syslog server using my vCenter as the example. 1) Navigate to your ESXi host within vCenter. Go to "Manage" tab and select "Settings" followed by "Advanced System Settings". Look for the settings "" and highlight this settings. Click the pencil icon to edit the configuration for this setting. 2) You can now add the host name or ip address of your syslog server/s. You can enter just hostname or IP address, use udp://hostname:514 or ssl://hostname:1514 to be more specific on the port and protocol to be used. If you have multiple hosts then you use the comma (,) to separate each server i.e. udp://,udp:// 3)We n

Custom ESXi Image - ISO using PowerCLI

There comes a time when you have purchased a new hardware to run your ESXi software and discover that the installable base media provided by VMware does not include the drivers or the drivers are out of date. In the world of Windows (Plug and Play) it would discover the hardware and prompt you to provide the drivers so that Windows would install/update the drivers for the hardware. For ESXi if the drivers are not present during load time then the hardware will possibly not work. VMware uses VIB (vSphere Installation Bundle) as a way for vendors to distribute their drivers. To install these VIBs you can either use Update Manager or command line (esxcli). Now this is all good but it does mean you have to first install the base ESXi then use one of the steps above to install/update the drivers.   Some people might feel that it is OK to update the drivers using the above methods but what if it was the network card that was the new hardware and you needed new drivers.
