VM /ETC

Archive for March, 2010

The virtualization community, my employer, and every Virtualization Service Provider I know is neck deep in virtual desktop infrastructure (VDI). Already important because of Windows 7 migrations, the announcements last week from Microsoft and Citrix seemed to have raised the intensity of an existing white hot spotlight on VDI. When Microsoft, the world’s leader in the desktop operating system market, decides to change their position to make it easier to implement and license virtual desktops then we all have to stop and understand what has happened. There has been a significant change, and there are good things in the future for those moving to virtualized Windows desktops. However, understanding exactly what these changes are and how they impact us continues to be a moving target changing rapidly each year.

This post is my summary of research about the latest Microsoft and Citrix announcements. I’m linking and quoting several bloggers and analysts to help VM /ETC readers (and myself!) digest the details of the new licensing and promotions. I also the outline the actual products that make up the Microsoft and Citrix VDI solution, and then finally point to some interesting reactions and perspectives published over the last several days. 

New Microsoft VDI Licensing

Most importantly, Microsoft declared a new licensing policy where Windows desktops will no longer need a separate license to be accessed via VDI by companies with Software Assurance. Although I could not specifically find it stated anywhere I looked, I assume this means whether accessed on any Microsoft VDI solution, VMware View, Citrix XenDesktop, or any other vendor’s VDI product. Here’s some additional information on the new licensing as intrepreted by others:

Desktop Virtualization: Microsoft, VMware in Cost Smackdown

http://www.networkworld.com/news/2010/031910-desktop-virtualization-microsoft-vmware-in.html?page=1

“One key part of the sweeping announcements, covered in an hour-long Webcast, is a simpler and cheaper model for licensing Windows in a virtual desktop environment. Specifically, on July 1, Software Assurance customers will no longer have to buy a separate license to access Windows via a VDI.

Moreover, for customers that use devices that don’t qualify for Software Assurance, such as thin clients and PCs used by contractors, there will be a new license called Windows VDA (virtual desktop access) available for $100 per device per year. This license will allow users to still have access to their complete virtual desktop outside the corporate network on devices such a personal laptops and airport kiosks.”

Maybe Microsoft is finally starting to abandon the concept of anchoring a Windows license to hardware and hopefully beginning to consider introducing virtualization editions of their operating systems? We are definitely not there yet, but at least it’s movement in the right direction.

Microsoft and Citrix VDI Promotions

Along with the new VDI licensing Microsoft and Citrix has also introduced some competitive promotions not only stimulate VDI migration but hopefully capture back some market share in the process. A new web site, citrixandmicrosoft.com, details these new offers.

A recent announcement from Likewise Software hints that future versions of VMware vSphere may make it easier for companies to manage ESX hosts using Active Directory (AD) credentials. vCenter, which runs on a Windows Server operating system, is commonly added to an AD domain already, but special configurations are necessary to authenticate ESX host access with domain credentials today. Here’s a clip from the announcement:

“The integration will enable VMware vSphere users to manage privileged user access with Microsoft Active Directory, providing large enterprises with a scalable means to improve authentication and access control in virtualized environments to help meet IT security audit requirements. Likewise is a member of the VMware Technology Alliance Partner (TAP) program.”

I recently ran across this announcement via virtualization.info’s article VMware to embed Likewise authentication in next vSphere, but originally read about it in the vreference.com post ESX 4.1 to include likewise AD authentication?

Likewise Open is an “open source application that joins Linux, Unix, and Mac machines to Microsoft Active Directory and securely authenticates users with their domain credentials.” The Open edition is free to download and use. Likewise also offers

Almost as if to segue from my recent Virtumania Podcast episode about type 2 hypervisors, VMware has announced the release of the public betas for the latest versions of their popular Workstation and Player desktop products. Touting several new features and performance improvements, VMware Workstation 7.1 and Player 3.1 betas can now be downloaded from their VMware Beta Community pages.

I am downloading my copy as I write this post, but several new features have caught my attention.

• Open GL 2.1 support for Windows 7 and Vista guests
• Improved graphics support enabling high resolution videos in VMs
• Autologin for Windows Guests
• Inclusion of the OVF 1.0 command line tool to convert VMs to .OVF files for exporting to other hypervisors
• 8 way vCPU support in VMs
• up to 2TB virtual disks
• Direct Launch – drag icon to host desktop and seamlessly start an application inside a VM – even after closing VMware Workstation or Player.
• Support for Fedora 12 as a guest OS
• VMware Ace upgraded to version 3.7

Also, I can’t help but notice Known Issues from the Release Notes such as the following:

“Display

• Exiting FIFA 08 game on Windows 7 guests and hosts with Aero enabled, might cause the desktop wallpaper to turn black.
• There are known issues with the ATI Linux driver 10.2. VMware recommends that you use ATI Linux driver 9.11 for the best 3D user experience.”

Looks like I’ve got some new testing to do! (and maybe a new 3D games video to make!)

The vSphere Enterprise Plus vNetwork Distributed Switch (vDS) has been heralded as, and I might add lives up to it’s reputation of, an administrator’s time saver and single point of virtual networking configuration and visibility across many ESX/ESXi 4 hosts. However, the vDS presents some administrative challenges unique from the traditional vNetwork Standard Switch (vSS) that admins are used to. Specifically, since the vCenter 4 Server actually maintains the vDS configuration, some extra design thinking needs to be built into a vSphere 4 environment where a vDS will be used. If vCenter 4 Server itself will be a virtual machine in the environment with a vDS, the design gets even more involved.

There are a few possible problems to consider. In this post I’ll first cover (with the help of a several others) general VM and vCenter vDS networking issues, but along the way I’ll explore thoughts about designing around a vDS for keeping vCenter as a VM.

Managing and troubleshooting ESXi 4 can be a little alien when an administrator is used to the Service Console of ESX Classic. Specifically, troubleshooting remote connectivity to the ESX management interface after adding a second NIC involves local esxcfg-vswitch commands on ESX, but with ESXi the esxcfg commands are only available via the RCLI. Problem is you can’t use the RCLI if you lost remote management connectivity! Luckily, the local ESXi GUI lets you reconfigure your mistake and re establish remote connections.

Hit F2 on the ESXi Console and enter the System Configuration Menu

  Choose to Configure Management Network > Network Adapters
