12 Common Hyper-V Deployment Mistakes

13 Nov by Eric Siron    3

I’ve seen a lot of questions from those who have recently deployed Hyper-V for the first time. Some just need a few pointers to iron some minor glitches, but some are in really bad shape. Here are some of the common deployment mistakes and their solutions. 1. Mis-Provisioning Resources in Hyper-V There are a lot…

As an IT Professional, you might find yourself blessed with the unfortunate scenario of working on a Hyper-V server that is not able to authenticate to the domain and the cached domain credentials are no longer working. In addition to this predicament, you learn that there is no documentation for the local administrator password. Either…

Live Backup Changes in Hyper-V Server 2012 R2

Live Backup Changes in Hyper-V Server 2012 R2

29 Oct by Eric Siron    0

Quite some time ago, we wrote a post about taking live backups in Hyper-V. Hyper-V Server 2012 R2 really changed the mechanics of backup. This post examines how those changes have affected live, or hot, backups. Until 2012 R2, backup was strictly based on VSS (Volume Shadow Copy Service) operations. Backup applications trigger VSS in…

Choosing a Management OS for Hyper-V: Windows Server

Choosing a Management OS for Hyper-V: Windows Server

16 Oct by Eric Siron    5

In the sister article to this piece, we talked about choosing Hyper-V Server over Windows Server as the management operating system. In this one, we’re going to go down the other road and make the case for Windows Server instead. A Clear Definition of Hyper-V Terms The earlier article had a section devoted to clearing…

Choosing a Management OS for Hyper-V: Hyper-V Server

14 Oct by Eric Siron    2

For the server edition of Hyper-V, you have a choice in management operating systems. You can use the free, no-GUI Hyper-V Server or you can use the full-fledged Windows Server. This will be the first of two articles in which I will argue both sides of the debate. In this installment, I’ll take the position…

Hyper-V and Networking Part 8: Load-Balancing Algorithms

Hyper-V and Networking Part 8: Load-Balancing Algorithms

09 Oct by Eric Siron    2

We’ve had a long run of articles in this series that mostly looked at general networking technologies. Now we’re going to look at a technology that gets us closer to Hyper-V. Load-balancing algorithms are a feature of the network team, which can be used with any Windows Server installation, but is especially useful for balancing…

Troubleshooting Hyper-V Guest OS Installations

Troubleshooting Hyper-V Guest OS Installations

25 Sep by Eric Siron    2

When it comes to ease of installation, Windows has always had a sketchy history. By the time Windows 2000 came out, most enthusiasts and professionals had learned to adopt a strategy of “installation by any means necessary”. What that meant was that we would take any steps, no matter how drastic, just to get the…

Introduction to Client Hyper-V

Introduction to Client Hyper-V

12 Aug by Andy Syrewicze    2

In talking with IT pros in the industry on a regular basis, I often see ebbs and flows of interest regarding specific topics or technologies, and one such topic that I’ve seen several inquiries on lately is Client Hyper-V. Its difficult to pin down any one reason, but whatever the cause, it’s very apparent there…

Hyper-V and Networking – Part 7: Bindings

Hyper-V and Networking – Part 7: Bindings

31 Jul by Eric Siron    0

So far, this series has spent most of its time focused on the methods that systems use to decide where traffic should go and how it should get there. A logical next step is to discuss how bindings work. I wrote about binding order earlier. What this article will do is bring the concepts of…

Hyper-V and Networking – Part 6: Ports, Sockets and Applications

Hyper-V and Networking – Part 6: Ports, Sockets and Applications

24 Jul by Eric Siron    0

In many ways, this particular post won’t have a great deal to do with Hyper-V itself. It will earn its place in this series by helping to clear up a common confusion point I see being posted on various Hyper-V help forums. People have problems moving traffic to or from virtual machines, and, unfortunately, spend…

Hyper-V and Networking – Part 5: DNS

18 Jul by Eric Siron    0

The last couple of posts in this series have dealt with how Ethernet frames and IP packets get to their destination. In this post, we’ll step up a little bit and look at the role DNS plays in getting those packets to the correct IP address. We’ll see how this works in general and the…

Hyper-V and Networking – Part 4: Link Aggregation and Teaming

Hyper-V and Networking – Part 4: Link Aggregation and Teaming

16 Jul by Eric Siron    2

In part 3, I showed you a diagram of a couple of switches that were connected together using a single port. I mentioned then that I would likely use link aggregation to connect those switches in a production environment. Windows Server introduced the ability to team adapters natively starting with the 2012 version. Hyper-V can…

Hyper-V and Networking – Part 3: IP Routing

18 Jun by Eric Siron    0

In the previous post, we dug into VLANs, which are a layer 2 concept in the ISO model. In this piece, we’re going to step up into layer 3 and look at IP address and routing and how they work with Hyper-V. Part 1 - Mapping the OSI Model Part 2 - VLANs Part 3 - IP Routing…

Hyper-V and Networking – Part 2: VLANs

12 Jun by Eric Siron    0

In the first part of this series, we started with the foundational concepts of networking in the OSI model and took a brief look at where Hyper-V components live in that model. In this part, we’ll build on that knowledge by looking at the operation of VLANs and how they work within the context of…
