Administer Hyper-V from Windows XP

December 28, 2009 3 comments

Windows XP is still by far most used operating system worldwide as you can see  here and here.  Also, virtualization is one of the most popular technologies and a lot of companies use Hyper-V as their virtualization solution. So then they have many XP clients (and licenses of course) which they would most likely want to use for remote administration of Hyper-V servers. Of course, Remote desktop can be used for that purposes in many different ways because Hyper-V allows administrators to define role-based access control for Hyper-V by using Authorization Manager. But let’s put that one aside, an let’s imagine that someone would like to use something similar to Hyper-V Remote Management Update for Windows Vista or Remote Server Administration Tools (RSAT) for Windows 7.

Ok, so in that case everyone can try Hyper-V management console; a small tool that can be installed on Windows XP, Windows 2003, 2008, Vista or Windows 7. Tool is rather easy to set up, you just need to enter names of your Hyper-V servers and that’s it. After that, from Windows XP you have :

  • Ability to monitor multiple Hyper-V servers
  • Ability to monitor all virtual machines
  • Ability to change state of virtual machines
  • Ability to delete, rename virtual machines
  • Ability to create, delete & apply snapshots
  • Ability to RDP to virtual machines
  • Ability to Import/Export virtual machines
  • Audit user activity
  • Display of virtual machines in List or Tree Views
  • Control of user rights to high degree of granularity

Where can I download the tool and how to install it?

  • Download the tool from here. Run HyperVConsoleSetup.msi. 
  • Choose administrative install. After that click only Next couple of times and then Finish. 
  • Run Hyper-V Management Console shortcut in your Start Menu. 

***Note: This is evaluation version so you’ll have ability to manage only two servers/VM’s   

  • After opening tool just right-click on Hyper-V Managers then  click on Connect to server and enter name of your Hyper-V server.
  • Click on following pictures to see how does the tool look like and what can you do with it.






Try and test Microsoft Enterprise Virtualization (MED-V) for free by using just Internet Explorer.

December 18, 2009 1 comment

Microsoft Enterprise Desktop Virtualization (MED-V), is a component of the Microsoft Desktop Optimization Pack (MDOP), which enables deployment and management of Microsoft Virtual PC Windows desktops. Main capability of MED-V is seamless application integration, so you can ran Windows 7 incompatible applications as they were installed locally on your host machine. Actually, applications are installed in XP virtual machine placed on your Windows host machine, and then application shortcuts are published to your Windows host Start menu. When user clicks on published shortcut, application launch normally (seamlessly integrated). MED-V is similar to XP Mode, meaning that with both products you can achieve seamlessly integrated applications, but MED-V is suitable for big organizations and XP mode is more suitable for smaller organizations. Also with MED-V you have centralized management of virtual images and policies. So now, after basic information about MED-V,  would you like to try it without installing anything? No problem Microsoft Virtual Labs are here to help you.

How can I try Microsoft Enterprise Desktop Virtualization (MED-V)  just by using Web Browser?

By using Microsoft Virtual Labs you can connect to live running server (similar to Remote Desktop Connection), and then complete some of the product scenarios. So to try MED-V :

  1. Click here.
  2. If you have all prerequisites (IE 6 or later, cookies enabled, Virtual Machine Remote ActiveX Control), click on Start Your Lab button, and your LAB will open in IE window.
  3. NTLM Authentication will appear. Click Yes.
  4. Begin Scenario, using Exercise 1.

With this LAB you will experience MED-V in standard scenario of application compatibility. This test lab is available as part of Windows 7 Test Drive where you can also try BranchCache, DirectAccess, BitLocker and other interesting features and scenarios.

Windows Server 2008 R2 Failover Cluster error / warning: SCSI 3 persistent reservation failed / CSV redirected access

December 4, 2009 4 comments

Topic of this blog post is actually based around two possible errors/ warnings regarding Hyper-V cluster and Cluster Shared Volumes:

  • Cluster Validation Wizard:  Validate SCSI-3 Persistent Reservation    – Failed”
  • Unable to turn off Redirected Access on Cluster Shared Volumes (CSV)

Anyway both problems are influenced by one tiny configuration step in your storage vendor and can be solved with following steps (if your storage supports that):

  1. Log in to your storage vendor management console.
  2. Go to configuration of hosts connected to storage.
  3. There you will see one drop down menu where you can choose Microsoft Windows LH or Windows Server 2008 entry. If you have option for Windows Server 2008 choose that one and if you have option for Microsoft Windows LH choose that one.

By doing that you will resolve issue in validation wizard and also issue in Cluster Shared Volumes where you can’t turn off redirected access.
