VMware Flings: Embedded Host Client Update

I am excited about the release of VMware Labs Flings release of  version 3 of the Embedded Host Client. For those of you who find yourself out of the loop at time, no worries it happens.  Here is some details about the the embedded host client:

The Embedded Host Client is written purely in HTML and JavaScript, and is served directly from your ESXi host. The installed client is in its development phase at this time and does not have full feature sets, but has implemented a very useful feature set.

These features include:

  • VM operations (Power on, off, reset, suspend, etc).
  • Creating a new VM, from scratch or from OVF/OVA (limited OVA support)
  • Displaying summaries, events, tasks and notifications/alerts
  • Providing a console to VMs
  • Configuring host networking
  • Configuring host services

 

Installation Steps:

  1. Enable SSH on your ESXi host, using DCUI (Direct Console User Interface) or the vSphere web client.
  2. SCP the VMware_bootbank_esx-ui_0.0.2-0.1.3172496.vib to a directory on your ESXi host. In my case I used a shared storage LUN or NFS volume as I will apply this to multiple hosts.
  3. Next issue the following command:

     

Upgrade Steps

OVF Deployment Issue Ubuntu Snappy 15.04-stable (5 cloud)

When you have time, you do something.

Tonight I was headed over the Ubuntu site to grab me the latest version because I was thinking of installing OpenStack when I noticed on their landing page and noticed “Get Ubuntu Core” ; yes something new.

But where is my Raspberry Pi? No worries they have OVF images I can use to deploy to my vCenter Lab here at home. So I started just this and encountered an issue I once had.

Lets walk you through my events.

Downloading the image

  1. Found myself on the Ubuntu Internet of Things landing page: http://www.ubuntu.com/internet-of-things
  2. Located the OVF section of the getting started page: http://developer.ubuntu.com/en/snappy/start/
  3. Downloaded the OVA image (x86): 15.04/stable

Deploying the OVF Template 

  1. Using the vSphere Client, connected to vCenter (or stand alone ESXi host)
  2. Select server to deploy to and choose file > Deploy OVF Template
  3. Browse to the path were you downloaded your OVF image and select it

This is when I received the following error:
The following manifest file entry (line 1) is invalid: SHA256(core-stable-amd64-cloud.ovf)= d4b8922ed38a4eb9055576f7b46f8e92f463398298f3a42af942f25457d4d41c

Troubleshooting Step 1

  1. I extracted the OVA image (core-stable-amd64-cloud) with 7zip
  2. Once extracted attempted the steps detailed above “Deploying the OVF Template”

The same error was thrown once more.

Troubleshooting Step 2

Within the extracted folder exists the following file types: certificate, manifest, ovf (instruction / configuration) and disk image

  1. I remove the SHA256(core-stable-amd64-cloud.ovf)= d4b8922ed38a4eb9055576f7b46f8e92f463398298f3a42af942f25457d4d41c line from the .MF (manifest)
  2. Once removed I attempted the steps detailed above “Deploying the OVF Template”

It failed also, only this time the error started the the remaining SHA256 was also invalid.

Troubleshooting Step 3 – Third time is the charm

  1. Moved into the extracted OVA folder
  2. Deleted the .mf (manifest) file
  3. Followed steps above “Deploying the OVF Template” only this time using the OVF located in the extracted folder

This go around everything worked

So why did this happen?

The template was changed after its creation which invalidated the SHA256 key.  I have made templates myself, only to have to edit something out such as removing a CD Rom reference which later caused me issues.

I hope this helps if you face this incident or something similar

Tech Short Q&A: What is vCenter Single Sign-On For

What is vCenter Single Sign-On?

vCenter Single Sign-On is a feature of VMware vCenter 5, 6 and future vCenter implementations that is an authentication broker which also creates security tokens providing a secure way of accessing your environments.

This token exchange mechanism is far superior than the former requirement of each component authenticating separately with a directory service such as Active Directory. Its VMware’s answer to identity management

Here are some key capabilities of SSO?

  • add multiple AD domains, OpenLDAP, and the local operating system where SSO is deployed. It also lets you create local users and groups.
  • allows VMware vSphere to connect to a non-AD Identity Source, OpenLDAP.
  • supports the SAML 2.0 standard and WS-TRUST, both of which are open industry standards.
  • lets users delegate tasks to solutions that can run as the identity of the user.
  • supports identity delegation for long-lived tasks with the ability to renew tokens.

vCloud Air – I want it

From our friends over at VMware we now have news of vCloud Air. A public cloud platform built on the trusted foundation of vSphere, compatible with your on-premises data center, that includes infrastructure, disaster recovery.

With vCloud Air  you can migrate existing onsite virtual machines (VMs) to the public cloud.  vCloud Air’s billing mode uses the IaaS (infrastructure-as-a-service) model making it very appealing for testers and developers looking for short term environments as well is companies looking to expand into new infrastructure without the need to acquire new hardware.

Best of all, its using the same vCenter, ESXi environments you come to know, trust, support and *love.

Checkout the CPU performance and I/O performance comparisons for more information.

vCloud Air has the  Support and Services You Know to help you extend beyond your data center.

Oh and vCloud Air 35% Cheaper Than Azure and 83% Cheaper Than AWS
