Automating Customer Experience Improvement Program (CEIP) configuration using vSphere API and PowerCLI

01/24/2019 by William Lam 2 Comments

After publishing my recent article on the new the vSphere Health capability which takes advantage of VMware's Customer Experience Improvement Program (CEIP), I had a couple of folks reach out asking how their customers could check whether CEIP is enabled for a given vCenter Server and if not, how to enable it using Automation. For one of these customers, they had over 25+ vCenter Server, so they were not interested in doing this by hand and nor should they.

For those interested in the vSphere UI, the CEIP settings is configured in the Administration menu under the Deployment section as shown in the screenshot below.

We can also manage the CEIP settings programmatically using vSphere API and this is controlled by an Advanced vCenter Server setting called VirtualCenter.DataCollector.ConsentData. The value of this property is actually a JSON payload as you can see in the screenshot below and when updating this property, we need to update both the change version as well as whether we want CEIP enabled or disabled for a given vCenter Server.

Instant Clone Microsoft Windows & VM Keystroke VMworld demo and code posted

Apologies for the delay in getting my VMworld 2018 demo and code posted online, I know a number of you have been asking about the Windows Instant Clone samples to get an idea on how to create your own customization scripts for managing more "recent" Microsoft Windows releases 😉 and perhaps you might even consider submitting a pull request to share with the community. I have posted both the videos and code samples below. Enjoy and happy Automating!

Instant Clone Microsoft Windows

To demonstrate the power of the newly re-architected Instant Clone feature in vSphere 6.7 and to help make the point clear that the Instant Clone feature is really Guest Operating System agnostic, meaning you can Instant Clone any to Virtual Machine that can run VMware Tools, I thought it would be fun to see how old of a Microsoft OS that I could Instant Clone. After a bit of trial/error, that turned out to be Windows 98 and Windows 2000 🙂

Managing Distributed Firewall Rules in VMC using PowerShell & NSX-T Policy API

01/04/2019 by William Lam Leave a Comment

Back in November 2018, VMware Cloud on AWS (VMC) SDDC 1.5 Patch 1 was released and it was one of the most highly anticipated release by our customers. Although this was a "patch" release, it included a ton of new features and also brought the full power of the NSX-T platform to VMC as a generally available feature!

With NSX-T, customers also now have access to the highly requested Distributed Firewall (DFW) capability which enables granular control over East-West traffic between application workloads. In addition to enabling micro-segmentation in VMC, customers can now easily manage DFW rules using a number of grouping constructs (Tags, Virtual Machines & Conditional Statements) to create dynamic policies which follow their workloads.

Customers can configure DFW (as well as Edge Firewall) rules using the VMC Console UI but many of you have been asking for an automated method, especially if you need to create a large number of policies for more than a couple of workloads. After returning from the holiday, I spent the last couple of days updating my NSX-T Policy PowerShell Module which now includes basic support for managing DFW. For those of you who are new to using the NSX-T Policy API and PowerCLI, be sure to give these two articles a read here and here before proceeding further.

Automating Hybrid Cloud Extension (HCX) Manager initial configuration for VMC

10/29/2018 by William Lam 2 Comments

Following up from my previous Hybrid Cloud Extension (HCX) Automation article which looked at deploying the HCX Manager OVA, this article will now focus on automating the initial configuration of HCX Manager including the registration to HCX Cloud which will enable the on-prem HCX Manager to be used with VMware Cloud on AWS (VMC). Once HCX Manager is up and running, customers can configure the system using the HCX VAMI interface which is available on port 9443 via the UI or in our case with the HCX VAMI APIs.

I have updated my HCX PowerShell Module to include 8 additional functions that can be used for initial configuration of HCX Manager:

Set-HcxVCConfig
Set-HcxLicense
Get-HcxNSXConfig
Set-HcxNSXConfig
Get-HcxLocation
Set-HcxLocation
Get-HcxRoleMapping
Set-HcxRoleMapping
Get-HcxProxy
Set-HcxProxy
Remove-HcxProxy

Is vCenter Server & ESXi hosts using VMware Certificate Authority (VMCA) or custom CA certificates?

10/23/2018 by William Lam Leave a Comment

Customers have two primary methods of managing TLS certificates for their ESXi hosts, they can either use the built-in VMware Certificate Authority (VMCA) which is part of vCenter Server or Custom CA Certificates. I will not go into the gory details, but you can read more about the options here in our documentation.

A question that I had received recently was whether you can determine the type of certificate an ESXi host was provisioned with and whether this could be programmatically retrieved using the vSphere API? The answer is yes. In vSphere 6.0, we introduced a CertificateInfo property which contains a number of fields including status, issuer, expiry and subject details and by inspecting either the issuer or subject property, you can determine the type of certificate on the ESXi host.

Here is a screenshot of the data using the vSphere MOB for an ESXi host that has VMCA-based certificate:

Here is a screenshot of the data using the vSphere MOB for an ESXi host that has custom CA certificate:

As you can see, for VMCA-based certificate the issuer's OU will have value of "VMware Engineering" and subject's emailAddress will have value of "vmca@vmware.com".
