How to identify/create computer groups that are in different Virtualization technologies

leave a comment »

Here’s a cool tip at “How to create a computer group for VMware servers or Hyper-V servers“.

Hyper-V Server Group
This process was very simple for the Hyper-V servers, as there is an existing attribute (Virtual Machine) that indicates if the server is virtual in Hyper-V. The steps to create this group from the Operations Manager console: Navigate to the Authoring space -> Groups, right-click and create a new group. We named ours Hyper-V virtual, and when we specified the dynamic members we defined them to where Windows Computer / Virtual Machine equals True.
VMware Server Group
For VMware, we needed to create an attribute that would identify systems virtualized with VMware, and then use the attribute to populate the group membership. From the Operations Manager console -> Authoring space –> Management Pack Objects –> Attributes, we right-clicked and created a new attribute. We labeled the attribute as VMware tools, provided a description, defined it to a target of Windows Computer (which set it to Windows Computer_Extended) based upon a registry key, and stored it in a custom MP (not the default MP shown in the screenshot below).

NO hardware-assisted virtualization for Windows XP Mode

leave a comment »

AS discussed in my previous post, Windows XP Mode no longer requires hardware virtualization technology.

Get the updates at:
KB977206-32Bit systems
KB977206-64Bit systems

Install this update to remove the prerequisites required to run Windows Virtual PC and XP mode. The prerequisites include a processor which supports hardware assisted virtualization (HAV) which is also enabled in the BIOS. After you install this item, you may have to restart your computer.

FINALLY – Hyper-V Dynamic Memory

with 2 comments

The day has come; Hyper-V Dynamic Memory will be added in W2008 R2 SP1. This is a new feature that many Hyper-V Admins were screaming about, thank you Microsoft 🙂

But that’s not the end of the good news…:)
According with Microsoft press release issued today, a bunch of new statements, including features, licensing and requirements changes are available. Here are some of them:

  • New VDI promotions
  • Improved licensing model for virtual Windows desktop
  • Windows XP Mode no longer requires hardware virtualization technology
  • Hyper-V Dynamic Memory
  • Microsoft RemoteFX
  • New technology agreement with Citrix Systems

In today’s webcast, Microsoft and Citrix executives, analysts, and customers will discuss today’s news and Microsoft’s desktop-to-datacenter virtualization strategy. Today’s webcast also marks the beginning of a 100-city, worldwide series of events to educate customers on the comprehensive portfolio of desktop and datacenter virtualization solutions provided by Microsoft and its partners, including Citrix. To join the dialogue, Twitter users can tweet their comments and questions to #MSVirt.”

Opsmgr troubleshooting of discovery scripts

leave a comment »

Having problems with discovery scripts? Don’t know how to troubleshoot them?

Check Kevin Holman blog where he explains how to perform Basic troubleshooting for discovery scripts.

Do you ever get script errors from a discovery scripts?  Or you aren’t discovering something that you feel should be discovered?

There are many ways to troubleshoot this discovery process, this will cover the “basics”.
First thing I like to do – is start with the console. 
1.  Find out what class your discovered object is missing from.  I will use SQL 2005 DB Engine as an example.
2.  Find out what discovery “discovers” this object.  Fairly easily – we can see that this discovery is “Discover SQL 2005 Database Engines (Windows Server)”
3.  Find out what class this discovery targets.  From looking at the discovery – we can see that this discovery targets the “Windows Server” class.

Hyper-V (VDI) Deployment troubleshooting tips

leave a comment »

Here’s a nice article from Remote Desktop Services Team Blog, where they explain common troubleshooting tricks for deploying RemoteApp for Hyper-V.

Similar to RemoteApp, the RemoteApp for Hyper-V feature allows users to access a specific hosted application remotely, as opposed to the entire desktop. When using RemoteApp, the application runs in the context of a server session; however, RemoteApp for Hyper-V enables remote access to an application running on a Hyper-V virtual machine (VM). That is, this feature allows you to launch applications that are hosted on VMs as remote applications.
