This week I’m playing with Windows Server 2012 R2 Hyper-V.

To start I thought I’d list the different type of Microsoft Virtualization

Microsoft’s basic definitions of the different types of Virtualization

Server virtualization.

You can use server virtualization to host a large number of virtual machines. Server Virtualization uses the Windows Server 2012 Hyper-V platform.

Desktop virtualization.

Desktop virtualization can refer to either client side virtualization, such as the Hyper-V client on a computer running Windows 8.1, or virtual desktop infrastructure, where the client computer operating systems run on a server virtualization host.

User state virtualization.

User state virtualization captures and centralizes application and Windows operating system settings for users. This enables users to sign in to any device while retaining their settings.

Presentation virtualization.

Presentation virtualization allows desktops and applications that are running on a Remote Desktop Services server to display on remote clients.

Network virtualization.

Network virtualization enables you to isolate networks used in server virtualization without requiring the implementation of virtual local area networks (VLANs).

Application virtualization.

You can use application virtualization to virtualize applications, which then enables applications to run in or be streamed to special containers on a host operating system.


Starting your training journey with Microsoft Private Clouds November 15, 2012

Now anyone who has read any of my posts may think that perhaps I’m a little bit biased towards VMware.

Really though I’m not. (Was he being sarcastic? No he’s not).

One of the things I like about Microsoft virtualisation is the fact that Microsoft are trying to make virtualisation available to all.

I joke in my classes that we can all afford Solid State Disks and also spend hundreds of thousands on storage, but in the real world we can’t.

Microsoft has produced a wonderful white paper entitled.

Flexible Storage with Windows Server 2012

I can see that Windows 2012 Hyper-V alongside System Center 2012 becoming a very sound solution for virtualisation.

As such I have included a list of some very useful and informative courses on moving to a Microsoft powered private cloud.

We’re now being bombarded with the Cloud, and we are now wondering, “should we move to the cloud?”

This can be a worrying time, we are told that it will reduce costs, it will make our IT environment more agile, it will empower us, etc.

Wouldn’t be nice if we could get a useful assessment of our environment, and then use this information to help make the decision about moving to the cloud.

The decision to deploy cloud computing is a strategic one. Many organizations are curious to learn more about their IT environments and evaluate whether deploying cloud services is appropriate.

Well, Microsoft has provided us with a tool to help make that decision.

Take a short survey that assesses your current IT environment with regard to systems, processes, and productivity. The survey information creates a custom non-commercial report that provides recommendations on your IT state and helps you evaluate the benefits of cloud computing.

I was having a look around Microsoft’s website and discovered the evaluation VMs for System Center 2012 SP1.

The evaluation VMs are really useful as they are a prebuilt VM with Windows 2012 and System Center 2012.

Just to warn you though, they are huge and come down in 700MB chunks.

Microsoft Security Intelligence Report October 21, 2012

As we move to the cloud, our data becomes distributed.

Internally we need to ensure that data is accessible to our internal users, we also need to ensure that data is accessible only by the users that require it.

However as we move our machines and data to the cloud we need to ensure that our data is secured, as the VMs containing the data may be hosted by a third party.

Microsoft, on a regular basis produce their Security Intelligence reports, they are full of useful information and definitely worth a look.

Virtualising Microsoft Active Directory Domain Controller August 11, 2012

Virtualising Microsoft Active Directory Domain Controllers has always given me cause for concern.

Not the virtualisation bit, that works brilliantly, but the snapshotting bit, and this is why.

AD DS replication uses InvocationID and USNs on each domain controller to determine what changes need to be replicated to other domain controllers. If a domain controller is rolled back in time outside of the domain controller’s awareness and a USN is reused for an entirely different transaction, replication will not converge because other domain controllers will believe they have already received the updates associated with the re-used USN under the context of that InvocationID. A virtual machine (VM) makes it easy for hypervisor administrators to roll back a domain controller’s USNs (its logical clock) by, for example, applying a snapshot outside of the domain controller’s awareness.

Or to summarise in English, be very careful with Snapshots in AD it may, I say may just STUFF YOUR AD, when you revert back for any reason.

Fortunately Microsoft gave us a fantastic document on virtualising Active Directory Domain controllers

But it gets even better, Active Directory for Windows 2012 was designed with the cloud in mind, so you may want to have Domain Controllers on premise and then have some sitting off premise, so Microsoft have given us features galore, read the link, it’s really rather all quite good

As you may be aware, I teach virtualisation courses, or to give them their fancy name, Cloud courses.

I teach VMware and Microsoft, I had a chap on a Microsoft course and he said that his company was setting up a cloud, and I said “Nice one, what type of cloud.” He looked at me and said. “Do you know, I have no idea.”

We had a bit of discussion and we decided that what he was going to have was a Private Cloud, meaning all his services were inside his firewall. A bit more of a chat and I remembered that I had read a book sponsored by Microsoft, which talked about various different cloud types. I passed the link onto my delegate, and I’ll now pass it onto you.

Solutions for Private, Public and Hybrid Clouds

Make sure to read chapter one for information on why cloud computing is the most efficient and cost-effective way to deliver computing resources to users according to your business needs.

All you need to know is that a cloud is white and fluffy, except for the current weather, they’re dark and menacing and hovering over the Leeds training center, probably the same for the rest of the country. We had summer, it was a week in May.

Office 365 free e-book from Microsoft, go on have a look July 6, 2012

I’ve been having a look at Microsoft Exchange 2010 SP2 and as a Microsoft Certified Trainer; I also get emails regarding various technologies.

One of the big growth areas in IT is cloud technologies; just looking at the offerings from Microsoft for example we see the new range of certifications, such as their Microsoft Certified Solutions Expert in Cloud technologies.

One of the emails I got from Microsoft related to a free e-book for Office 365, I know from reading various course offerings that Office 365 gets quite a few mentions, for example on the Microsoft Exchange 2010 administration course (the one I teach)

Why not have a look at the free e-book for Office 365

This book shows you how you can use cloud computing – specifically, Office 365 – to get more done, collaborate more easily, and work more flexibly than you ever have before.

If the content interests you and you wish to learn more QA have many fine courses on Office 365.

From the QA website go to the search box and type Office 365

Fixed in a tick, solving Mulicast issues in Hyper-V VMs July 3, 2012

Fixed in a Tick

I’m teaching a Hyper-V course this week in our Leeds office, and whilst here we had an issue with a Hyper-V virtual machine.

The machine was being used as a ghost server, with one machine connected and streaming down an image (Unicast) all was good, good speed, and the image dropped fine. However with multiple machine connected (Multicast) the speed dropped off and was unusable.

What we did was to go into Hyper-V manager, right click on the VM and edit it’s settings.

Then we highlighted the network adapter and enabled the following

Enable spoofing of MAC addresses we then retried the operation of multiple connections to the ghost server, and hey presto all was good, good speed and the images dropped fine.

Without enabling Enable spoofing of MAC addresses the following conditions apply, and that’s why Multicast didn’t work within the VM.

The virtual switch port that connects the virtual network adapter sends and receives packets that contain any valid MAC address.

The virtual network adapter MAC address cannot be moved or associated with another virtual switch port.

The virtual switch port does not forward unicast flooded packets (packets that are forwarded to all switch ports if the destination MAC address is not found in the switch forwarding table) to the virtual network adapter.

You cannot override the virtual network adapter MAC address configuration using the NetworkAddress key in the virtual machine registry.
