KnowledgeBase: Physical GPU in Windows Server 2012 Hyper-V settings is unavailable post domain join
Last week, Microsoft introduced KnowledgeBase article 2878821, discussing some strange behavior on a domain-joined Windows Server 2012-based Remote Desktop Virtualization host. When such a host is added to a domain and the default domain policy is applied, the option to select a physical GPU used for RemoteFX (within Hyper-V settings) appears to be unavailable.
I will be speaking at the UK VMUG Meeting in Leeds
When you regularly check the website of the UK Virtual Machine User Group (VMUG), you might have noticed that they have a series of meetings coming up in Manchester, Leeds and London. Now, when you scroll through on the details of the Leeds meeting on October 1, 2013, you might notice a couple of familiar […]
Cases where VM-GenerationID doesn’t help make Active Directory virtualization-safe, Part 2
Yesterday, I talked about the new Active Directory virtualization safeguards in Windows Server 2012 (and beyond) and how Joe Richards triggered me to think about cases where the Active Directory virtualization safeguards (powered by the new VM-GenerationID) don’t help make Active Directory virtualization-safe(r). In the first post, I talked about how the Active Directory virtualization […]
Cases where VM-GenerationID doesn’t help make Active Directory virtualization-safe, Part 1
Joe Richards posted an interesting blogpost a while ago on why Active Directory VM-GenerationID functionality is not an alias for Active Directory anti-USN Rollback functionality. In it, he makes some valid claims: You are only protected in very limited set of very certain very specific circumstances. The VM-GenerationID "triggers" are dependent upon the virtualization platform. […]
Active Directory in Hyper-V environments, Part 9
I have written a lot about Active Directory Domain Controllers and Hyper-V in this series. So far you’ve seen recommendations on host configuration, guest configuration, security and converting physical Active Directory Domain Controllers to virtual ones. Today, I’m covering anti-affinity.
KnowledgeBase: Active Directory database becomes corrupted when a Windows Server 2012-based Hyper-V host server crashes
As I’ve written before, Microsoft has made significant strides on making Active Directory Domain Controllers safe(r) to virtualize in Windows Server 2012. Sometimes, however, you encounter a situation that makes all that progress seem to disappear. Microsoft, last week, has released KnowledgeBase Article 2853952, describing such a situation.
Citrix XenServer joins the VM-GenerationID family
One of the new features in Active Directory Domain Services in Windows Server 2012 is Virtualization-safe(r) Active Directory. This feature makes it easier and safer to deploy and manage virtual Domain Controllers through the VM-GenerationID capability of the hypervisor platform.
I will be speaking at the UK VMUG Meeting in London
I just received confirmation on speaking at the UK Virtual Machine User Group (VMUG) Meeting in the Hilton Doubletree hotel in London on Tuesday May 21, 2013. I will be delivering my session on virtualization-safe(r) Active Directory and Domain Controller Cloning. The same session I have been delivering for the past year at numerous events, […]
List of Hypervisors supporting VM-GenerationID
Microsoft introduced the VM-GenerationID in Windows Server 2012, to enable Virtual Machines (VMs) to notice when they’re snapshotted, restored and/or cloned. Active Directory is the first technology to put the VM-GenerationID to good use. The following Hypervisors support VM-GenerationID: Windows Server 2012 Standard Edition (Hyper-V) Windows Server 2012 Enterprise Edition (Hyper-V) Hyper-V Server 2012 (Hyper-V) […]
Five Must-Have Hardware components to get the most out of Windows 8 (and Windows Server 2012)
Windows 8 offers many new features, compared to Windows XP, Windows Vista and even Windows 7. Some of these features are fantastic, but come with a top of the bill hardware price tag. In this blogpost I’ll explain why you’ll need to scour the specifications of your hardware components for these five acronyms
