Is there a vSphere REST API for ...

by // 8 Comments

Up until vSphere 8.0, there were two primary sets of vSphere APIs:

Note: Technically, there are other vCenter Server API endpoints including vSAN, Storage Policy Based Management (SPBM), etc. but for the purposes of this article, we are focusing on the core vCenter Server functionality.

The vSphere Web Services API was available starting with the Virtual Infrastructure (VI) 2.x release back in 2007. To date, the vSphere Web Services API supports the latest vSphere 8.x release and still also has full backwards compatibility going all the way back to Virtual Center 2.x!

As you can imagine, the vSphere Web Services API covers an extremely large amount of functionality over the past 16 years since its introduction and it continues to be widely used by almost all customers either directly or indirectly through the various vSphere SDKs including PowerCLI, pyvmomi (vSphere SDK for Python), govmomi (vSphere SDK for Go), Terraform Provider for vSphere to just name a few. In addition, we also have many 2nd party solutions from VMware and thousands of 3rd party offerings from our broader ecosystem of partners that provide integrations with the vSphere platform, all consuming the vSphere Web Services API!

New detailed GuestOS data in vSphere 8.0 Update 2

by // 5 Comments

Your workloads are constantly changing both from an application standpoint but also the underlying guest operating system (GuestOS) including patches and upgrades. While many organizations have a change management database (CMDB), it can still be a challenge to true up that information from when the workload was first deployed to what it is currently running.

Back in 2019, VMware enhanced VMware Tools to make it easier to identify applications and processes that was running within a VM and this also provided a programmatic way for retrieving this inventory information which could then be fed back into their CMDB.

Applications are not the only things that change inside of a VM, the GuestOS probably receives the most updates (patches/upgrades) and being able to accurately inventory this information without relying on an in-guest agent is still a challenge for many.

In vSphere 8.0 Update 2, we have enhanced the available GuestOS data using VMware Tools and we have also made it easier to inventory and collect this information even when the VM has been powered off.

ESXi on Lenovo ThinkStation P3 Ultra

by // 30 Comments

After getting hands on with the Lenovo P3 Tiny, which was my first time experiencing a Lenovo kit, I was recommended by the Lenovo team to also check out its larger and more powerful sibling the Lenovo P3 Ultra.


While many of the smaller form factor systems have gotten more capable over the years, especially the classic 4x4 kits, they do have their limits in terms resources and expandability.

It has been some time since I have looked at larger kits but after glancing at the P3 Ultra specs, I can see why the Lenovo team thought this might be of interests to the VMware Community, especially with all the additional capabilities, packed into a larger but still pretty compact form factor design.
