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.

Tech Short: Enable SNMP on ESXi 6

Now that you are on or you have just started using VMware ESXi 6 and would like to do some monitoring via SNMP here is a way to enable this and set the community string in the process.

By default, remote clients are prevented from accessing services on host, unless configured to start automatically.

While you can simple set SNMP to start it does not set the community name and this is where we drop into the cli to do this.

Connect to the ESXi 6 host terminal or via SSH and issue the following commands:

By doing the following you have set the community strong value and started the service.

Back on vCenter in my home lab

Oh yeah; anyone else have the warm fuzzy feeling right now; Hashtags: #‎VMware‬ ‪#‎vCenter‬ ‪#‎ESXi‬

 

All in my home lab. Once again I have the management capabilities over systems that I prefer. VMware vCenter 6 is awesome and I am in love with the web interface

Next — Storage upgrade 3.0. That will be 16TB of usable RAID10 storage


There will be NFS, iSCSI and DLNA, and SAMBA

VMware vSphere PowerCLI – Power Off & On Guests

Looking for a method to restart a non-persistent environment in ESXi or vCenter, I was able to use PowerCLI to issue the commands needed. Originally I was looking to automate the recovery of a snapshot when it dawned on me that a non-persistent disk would facilitate the same thing.  However I would need to power off the server and back on again for it to work.

And this is what came from my searching and trial and error

Powering Off

Powering On

Both – Power Off wait then Power On

Next was to use a batch file to run a task to execute the PowerCLI commands. This was done by doing the following set as a scheduled task

Importing Virtual Machine Templates: vCenter

Note:
In most cases, only system administrators can import virtual machines from vCenter

To import a virtual machine template from vCenter

In the left pane, select VM Templates.

Click Import VM Template.

Type a name.

(Optional) Type a description.

Select vCenter and select a virtual machine that is not managed by Lab Manager.

Click Next.

(Optional) Deselect the Perform customization check box if you do not want Lab Manager to customize the network settings for the virtual machine template or virtual machines based on the virtual machine template.

Specify the networking information for each NIC in the imported virtual machine template:

Select the Connected check box.
Choose a default virtual or physical network.
Choose a default IP addressing mode.

Select a storage lease.

Select a deployment lease.

Select the datastore to which you want to import the virtual machine template.

Select whether to copy or move the source virtual machine template.

If you copy the virtual machine template, it continues to exist in the original location, but if you move the virtual machine template, it will not exist in this location.

Click Import and then you wait…

Lab Manager imports the virtual machine template into the current organization and displays it on the VM Templates page.
