I recently stumbled upon a Citrix Windows KMS license activation bug that I thought would be good to share along with a workaround. The bug appeared after I created machines from a Windows Server 2022 Datacenter Azure Edition virtual machine template using Citrix Machine Creation Services (MCS). The Windows Server 2022 Datacenter Azure Edition version was 21H2 (OS Build 20348.2322). The machines are created just fine, but when trying to log in to a virtual desktop, I noticed the “Activate Windows&rdq... read more.

In today's age of digital collaboration, using tools like Microsoft Teams in virtual desktop infrastructure (VDI) environments is more important than ever. We've recently had customers ask how well the new Teams client will work in VDI, especially with support for classic Teams ending on June 30th. The new Teams version has some great new features, but there's a catch: it isn’t fully supported on Windows Server 2019 and doesn't work on Windows Server 2016 at all. This can be tricky for businesses usi... read more.

Recent developments from Broadcom regarding VMware's offerings have sparked significant discussions within our organization and our client base. As we dive deeper into these changes, I thought I would write this blog post to discuss two recent changes that I have been asked about and their potential impacts. The End of an Era: Discontinuation of ESXi Free With over a decade of availability, VMware has decided to discontinue the free version of its ESXi hypervisor (versions 7.x and 8.x), marking the end of... read more.

Content Libraries For those entrenched in virtualization, vSphere's Content Libraries are no stranger. Despite their glaring advantages, the adoption rate has been sluggishly low, primarily because of traditionalist tendencies. Yes, you guessed it right, I'm talking about those dedicated LUNs still holding ISOs like it's 2005. I get it, it's comfortable to stick with what you know, but hear me out: Content Libraries in vSphere aren't just a fancier vessel for your ISOs. They are the bedrock for a more robu... read more.

Do you have any Raw Disk Mappings (RDMs) in your environment? If so, you might want to learn more about Clustered VMDKs. Clustered VMDKs vs RDMs Before Clustered VMDKs, clients would have to use RDMs to present a shared disk between VMs. RDMs were basically LUNs passed directly through the ESXi host to the Virtual Machines. The cluster software then handled writes and locking directly with the SAN. You could abstract the interactions a bit more by using Virtual Raw Disk Mappings (vRDMs), but the gist of t... read more.

Gotham has been delivering secure applications to client machines for over 20 years. In the past, this was done primarily through local installs, published applications, and virtual desktops. However, the application landscape is changing, and applications are now being delivered from more sources to more destinations. This includes SaaS applications, applications delivered from multiple brokers, multiple operating systems, and policy-based variations of the above scenarios. One example of this change is t... read more.

On July 14, 2022, IGEL announced the general availability of Microsoft Teams optimizations in Azure Virtual Desktop (AVD) using IEGL OS endpoints. IGEL OS is the first Linux-based OS to support Teams optimizations with AVD. Prior to this, the Teams optimizations were only available in the AVD clients for Windows 10/11 and macOS. The media optimizations for Teams allow for local offloading of audio and video for calls and meetings. This means that the audio and video traffic bypass the virtual desktop sessi... read more.
