VMware Explore 2024

Sep 012024

I’m finally back at home after an amazing week at VMware Explore 2024, in Las Vegas!

As always, VMware Explore 2024 was the place to be, and THE most important conference of the year, at least for me, my clients, and those who need to be in the know.

See below for my insights on the conference, information and links, as well as some videos I created to talk about!

The Focus moving forward

This was the first VMware Explore with VMware by Broadcom. With the acquisition of VMware by Broadcom, there’s been a number of changes they have implemented, including their new strategy moving forward, SKU consolidation, as well as solution refinement.

The focus this year was on VCF, also known as VMware Cloud Foundation, with the announcement of VCF 9.0, and enabling technologies like AI (Artificial Intelligence) with VMware Private AI Foundation, and NVIDIA AI enterprise.

Why VMware Explore is important for me

For me, VMware Explore is important because of a number of different things. A brief of this is:

VMware By Broadcom
- Strategy
- Product Releases
- Technical Sessions (Learning, Training)
- Hands on Labs (HoL)
Community
- VMUG – VMware User Group
- VMware vExpert
Networking
- Reconnecting in person with clients in other cities (and other countries)
- Meeting customers face to face for the first time
- New Business

I can’t recommend enough how important VMware Explore is for career development. It’s a face paced conference, and you won’t have time to do everything you plan and want to, but you just need to go with the flow and let it happen naturally.

Technical Sessions

There was a number of AMAZING technical sessions, which are all available via the VMware Explore content catalog (click the link to view).

You can also view various community sessions, by going to VMware TV Live (click for link).

VMware Explore 2024: Debrief and takeaways

Getting back home, there was a lot to take in and process, however I wanted to do a quick debrief and takeaway video.

In this video, I talk about:

Broadcom’s vision for VCF
Evolving world of IT
Corporate IT strategy shift
- Private AI
- Private Cloud
Practical AI use cases

Towards the end of the video, I also shared my thoughts on the last session I attended, called “GenAI-Powered Insights in Avi LB: A Journey into Next-Gen Observability“. You can click on the session name to find out more information and watch the video.

The session covered a real-world practical use of AI in IT, using an LLM to provide insight, analysis, administration, monitoring, and management of the VMware Avi Loadbalancer, using LLMs, with the choice of using Google Gemini in the cloud, or your own LLM on-prem using NVIDIA AI Enterprise, NIMs, and VMware Private AI Foundation.

Cool stuff!

VMware Explore, moving forward…

Moving forward, I’m aligned with and believe in the strategy of Private Cloud first, enabling technologies such as AI, while providing existing solutions such as compute.

I can’t wait for VMware Explore 2025!

Windows 11 Microsoft Account Center

Omnissa Horizon, Windows 11 2 Responses »

Aug 162024

Recently, new deployments of Windows 11 (23H2 images with the latest updates) have changed the behavior of the start menu and introduced the Windows 11 Microsoft Account Center.

This also effects 24H2, however 24H2 isn’t supported on Omnissa Horizon as of yet (to my knowledge) and probably most other VDI platforms, but this will be a concern once support is available.

The introduction of the Microsoft Account Center in the Windows Start Menu will become an issue for VDI deployments, as it changes the behavior of the Start Menu, and introduces some complexities for logging off users as well as introducing the need for training or alternative methods for users to log off.

Behavior

When clicking on Start and proceeding to click on the user name, users are no longer prompted with options like “Sign out, Switch User, Account Settings”. Users are now presented with the new “Microsoft Account Center”, which on non-VDI deployments provides actions for the Microsoft Account. Optimizing your image may slightly change the behavior of the Microsoft Account Center.

Here is an example of the original start menu:

Screenshot of the traditional Windows 11 start menu with user icon.

Here is an example of the new start menu with the new Microsoft Account Center:

Screenshot of new Microsoft Account Center on Windows 11 Start Menu

Users, who are expecting to be able to sign out, will not have to click on the “…” on the top right.

Additional Considerations

In addition to the examples provided above, the following behaviors can be expected:

On the base image, clicking the user icon will do nothing (and may possibly kill the start menu)
In deployments with Hybrid domain joined Instant Clones
- If the machine hasn’t achieved Hybrid Domain Join, clicking the user account icon will function.
- If the machine has Hybrid domain joined but a PRT has not been issued, click the user account icon will kill the start menu.
- If the machine has Hybrid domain joined and a PRT has been issued, it will perform properly using the new style.
In deployments with Hybrid Domain Joining and PRT disabled, the new “Microsoft Account Center” from the user icon, should function properly with the new style.

As of today, I haven’t seen the latest Windows Updates change older base images, but I haven’t had the opportunity to sample a large enough number of environments. If this occurs, you may need to brief users on how to log out using the new “Microsoft Account Center”, using the “Log Off” function on the Horizon Client, or possibly even create a desktop shortcut for the users.

Workaround

To workaround this issue, you may need to train users on the new behaviour, advise them to Log off with the VMware Horizon client (proper logoff, not just clicking the “X” which will only disconnect sessions), or create a “Log off” shortcut on their desktop.

I will continue to investigate and update this post, hopefully ultimately with a fix.

I have created a thread on the Omnissa Community Forums, Windows 11 23H2 – Start Menu, Account Icon Behavior Warning.

vGPU Mixed Size Virtual GPU types with VMware vSphere 8U3

NVIDIA, NVIDIA vGPU, Omnissa Horizon, vSphere 6 Responses »

Jun 262024

I’m happy to announce today that you can now deploy vGPU Mixed Size Virtual GPU types with VMware vSphere 8U3, also known as “Heterogeneous Time-Slice Sizes” or “Heterogeneous vGPU types”.

VMware vSphere 8U3 was released yesterday (June 26th, 2024), and brought with it numerous new features and functionality. However, mixed vGPU types deserves it’s own blog post as it’s a major game-changer for those who use NVIDIA vGPU for AI and VDI workloads, including Omnissa Horizon.

NVIDIA vGPU (Virtual GPU) Types

When deploying NVIDIA vGPU, you configure Virtual GPU types that provide Workstation RTX (vWS Q-Series), Virtual PC (vPC B-Series), or Virtual Apps (vApps A-Series) class capabilities to virtual machines.

On top of the classifications above, you also needed to configure the Framebuffer memory size (or VRAM/Video RAM) allotted to the vGPU.

Historically, when you powered the first VM, the physical GPU that provides vGPU, would then only be able to serve that Virtual GPU type (class and Framebuffer size) to other VMs, locking all the VMs on running on that GPU to same vGPU type. If you had multiple GPUs in a server, you could run different vGPU types on the different physical GPU, however each GPU would be locked to the vGPU type of the first VM started with it.

NVIDIA Mixed Size Virtual GPU Type functionality

Earlier this year, NVIDIA provided the ability to deploy heterogeneous mixed vGPU types through the vGPU drivers, first starting with the ability to run different classifications (you could mix vWS and vPC), and the later adding support for mixed-size frame buffers (example, mixing a 4Q and 8Q profile on the same GPU).

While the NVIDIA vGPU solution supported this, VMware vSphere did not immediately add support so it couldn’t take advantage of this until the new release of VMware vSphere 8U3, VMware vCenter 8U3, and VMware ESXi 8U3.

To configure different classifications (vWS mixed with vPC), it requires no configuration other than using a host-driver and guest-driver that support it, however to use different sized framebuffers, it needs to be enabled on the host.

To Enable vGPU Mixed Size Virtual GPU types:

Log on to VMware vCenter
Confirm all vGPU enabled Virtual Machines are powered off
Select the host in your inventory
Select the “Configure” tab on the selected host
Navigate to “Graphics” under “Hardware”
Select the GPU from the list, click “Edit”, and change the “vGPU Mode” to “Mixed Size”

Screenshot showing the "Graphics Properties" for GPU adapters on VMware ESXi 8U3 with the "vGPU Mode" set to "Mixed Size"

Once you configure this, you can now deploy mixed-size vGPU profiles.

When you SSH in to your host, you can query to confirm it’s configured:

[root@ESXi-HOST:~] nvidia-smi -q

    vGPU Device Capability
        Fractional Multi-vGPU             : Supported
        Heterogeneous Time-Slice Profiles : Supported
        Heterogeneous Time-Slice Sizes    : Supported
        vGPU Heterogeneous Mode           : Enabled

It’s supported, and enabled!

Additional Notes

Please note the following:

When restarting your hosts, resetting the GPU, and/or restarting the vGPU Manager daemon, the ESXi host will change back to it’s default “Same Size” mode. You will need to manually change it back to “Mixed Mode”.
When enabling mixed-size vGPU types, the number of some types of vGPU profiles may be reduced vs running the GPU in equal-size mode (to allow other profile types). Please see the additional links for information on Mixed-Size vGPU types inside the “Virtual GPU Types for Supported GPUs” link.
Only “Best Effort and “Equal Share” schedulers are supported with mixed mode vGPU. Fixed Share scheduling is not supported.

NVENC offload disabled when using RDSH with NVIDIA vGPU

NVIDIA vGPU, Omnissa Horizon, Remote Desktop Services (RDS) No Responses »

May 262024

When using Omnissa Horizon (formerly VMware Horizon), you may note that NVENC offload is disabled when using RDSH with NVIDIA vGPU. This may also affect other VDI and Application Delivery platforms that use RDSH (Remote Desktop Session Hosts) and NVIDIA vGPU (Virtual GPU).

One of the key benefits of deploying NVIDIA vGPU with Omnissa Horizon, is being able to use the NVIDIA NvENC (NVIDIA Encoder) to hardware encode your VDI session. This is also known as H264/H265/HEVC/AV1 offload.

This means that the encoding and compression of the remoted video session is handled by the GPU, instead of the CPU, freeing up resources on the VM guest and host, reducing latency with encoding, and also providing a much better user experience.

The Observation

When deploying NVIDIA vGPU with vApps and Horizon Apps, you’ll note the following in the VMware Horizon Performance Tracker:

VMware Horizon Performance Tracker on RDSH showing software encoder

You can see above that the “Encoder Name” is using “h264 4:2:0”. This means that the CPU Software Based encoder is handing the encoding of the H264 BLAST Session. While the environment is 3D accelerated, the remoting protocol encoding is not hardware offloaded.

You’ll also note the following:

VMware Horizon Agent High CPU Usage
“nvidia-smi” on the host and VM does not report the encoder being used

This behavior is as expected due to the inability of RDS session hosts to be able to utilize NvENC. RDSH hosts utilize a software framebuffer for user environment and desktop delivery which cannot be used with NVENC.

Solution and/or Workaround

To work around this limitation, you have the option of using VDI desktops (in this case it would be preferable to use non-persistent Instant Clones) to deploy an “Application Pool” with vGPU enabled VMs.

Note that this is a major change to your solution architecture because pushing applications (and desktops) from Windows 10 or Windows 11 Guest VMs is a 1 to 1 relation, versus RDSH which supports many users to one VM.

Using Horizon, you could then push applications (not desktops) from these vGPU enabled Instant Clones, which would support NVENC and hardware offload, as shown in the example below:

VMware Horizon Performance Tracker showing NVIDIA NvEnc Hardware encoder on instant clone

In the image above, you’ll note that the “Encoder Name” is “NVIDIA NvEnc HEVC 4:2:0” showing us that NvEnc hardware offload and encoding is functioning and being used.

Note, that using this method to deploy Horizon Apps will result in more framebuffer being required, however may be offset since a smaller framebuffer can be used with individual VMs versus a large framebuffer being assigned and attached to an RDSH host.
