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.

Active Directory and Personal Virtual Desktops

leave a comment »

Here’s a nice article from Remote Desktop Services Team Blog, that explain de Active Directory schema requirements for virtual desktop pools and personal virtual desktops.

Microsoft’s VDI solution offers two deployment scenarios: virtual desktop pools and personal virtual desktops. Virtual desktop pools are not dependent on a specific Active Directory schema level; however, personal virtual desktops do need a Windows Server 2008 or Windows Server 2008 R2 schema.

Here are the Active Directory requirements for personal virtual desktops:

  • To deploy personal virtual desktops, your schema for the Active Directory forest must be at least Windows Server 2008. To use the added functionality provided by the Personal Virtual Desktop tab in the User Account Properties dialog box in Active Directory Users and Computers, you must run Active Directory Users and Computers from a computer running Windows Server 2008 R2 or from a computer running Windows 7 that has Remote Server Administration Tools (RSAT) installed.
  • You must use a domain functional level of at least Windows 2000 Server native mode. The functional levels Windows 2000 Server mixed mode and Windows Server 2003 interim mode are not supported.

leave a comment »

AdExplorer v1.3: This update to AdExplorer, an Active Directory editor, has major node expansion performance improvements and a number of minor bug fixes.

VMMap v2.6: VMMap, a powerful process virtual and physical memory analysis tool, now shows both graphical and numeric breakdowns of private virtual memory, as well as heap configuration flags.

Disk2vhd v1.5: Disk2Vhd v1.5 works with Hyper-V SCSI direct-attached volumes and reports an error when a snapshot includes offline volumes.

LiveKd v3.14: This version of LiveKd has better detection of the Debugging Tools package installation and launches the debugger in a mode that skips the unnecessary root-cause analysis of the virtual dump file.

Sigcheck v1.66: This update to Sigcheck, a file version and signature checking utility, fixes a bug in the certificate revocation check logic.

System Center Virtual Machine Manager 2008 R2 KB980863

leave a comment »

As per KB980863 

You put a failover cluster node into Maintenance mode by using the console in Microsoft System Center Virtual Machine Manager 2008 R2. Then when you restart the node, you find that the groups fail back to the host node.

This issue occurs because the Failback policy for the group is set to Allow Failback.

Solution:
To resolve this issue, disable the Allow Failback option while the failover cluster node is in Maintenance mode.
Note This applies to System Center Virtual Machine Manager Maintenance mode and not Cluster Maintenance.

How to apply Opsmgr hotfix in a clustered RMS

leave a comment »

Once again Kevin does a great job explaining step by step about “How to apply a SCOM hotfix to a clustered RMS“.

The challenge is – that several SCOM hotfixes will make changes to the database, while being applied to the RMS.  They expect the SDK service to be running locally, so they can accomplish this.  This FORCES us to always apply a SCOM hotfix to the active node (under the current design).”
