New Book on Hyper-V Security

My second book is now available for purchase. Its name is Hyper-V Security. It’s a short-form book with only eight chapters. The first six are related to the host, the hypervisor, and the guests. The final two chapters were written by Andrew Syrewicze and cover security in System Center Virtual Machine Manager.

Video Series Image

Building and Managing a Virtual Environment with Hyper-V Server 2012 R2 is a video series designed to present the complexities of Hyper-V and failover cluster configuration in easily digestible chunks. The segments feature demonstrations of the concepts explained in the video, being executed on an actual Hyper-V cluster.

You’ll begin with the basics of setting up your nodes, gathering them into the cluster, and working with your shared storage system. Then you’ll get an in-depth tour of managing your systems using the built-in graphical tools and PowerShell cmdlets. With that foundation, you’ll learn advanced concepts of virtual machine migration and cluster protection. You’ll also discover detailed maintenance steps, such as how Cluster-Aware Updating keeps your nodes patched without impacting virtual machines.

Building and Managing a Virtual Environment with Hyper-V Server 2012 R2 will present you with the knowledge and examples you need to successfully design and deploy your own Hyper-V clusters.

My Hyper-V Cluster Book is Published

I have written a book dedicated to Hyper-V 2012 and 2012 R2 in a cluster configuration. Read more of this post

Explaining the Hyper-V Virtual Switch

I’ve been lurking in a few Hyper-V forums over the past few weeks, and I’ve noticed that people really have a hard time understanding the Hyper-V virtual switch. Even worse, a lot of the “experts” valiantly trying to help them out don’t seem to really get it either. A lot of them do get it, but have a hard time trying to explain it. So, I put together a two-part series where I try my hand at explaining the basics of this technology. You can find it on the Altaro site.

Jumbo Frames and Converged Fabric in Server/Hyper-V 2012

I’ve added a new post on the Altaro site. Its original purpose was to illustrate how to get virtual adapters on a virtual switch to support jumbo frames, but along the way I also demonstrate how to build a converged fabric to use for the server roles as well. Read it at: http://www.altaro.com/hyper-v/how-to-adjust-mtu-jumbo-frames-on-hyper-v-and-windows-server-2012/

Hyper-V Network Binding Order

A message from a LinkedIn member prompted me to look into how binding order works in the Hyper-V world. After looking around, I found out that this was a much larger issue than I knew. So, I’ve put together a comprehensive blog post that covers the issue. You can read it on the Altaro blog. It is applicable to both Hyper-V R2 and 2012.

Dell OpenManage Server Administrator 7.1 on Server Core or Hyper-V

Dell has done something to the installer for the recent version of OpenManage Server Administrator so that it doesn’t work on Server Core, which includes native installations of Hyper-V.

Symptoms

  1. Running “X:\windows\PreReqChecker\RunPreReqChecks.exe /s” errors out with “omchecks has stopped working”
  2. The installer (accessed by running “msiexec /i X:\windows\SystemsManagement\SysMgmt.msi” stops with the error “Failed to load OMIL library”

Solution

Install OpenManage Server Administrator 6.5 first (the command on that CD is “msiexec /i X:\SYSMGMT\srvadmin\windows\SystemsManagement”). As soon as that installer finishes, you’ll be able to install 7.1 without error. If you haven’t got the older installation media, you can download it from Dell’s site. If your particular server is too new to have 6.5 available, check the download list for earlier servers, such as the PowerEdge R515.

You do not need to perform any cleanup on 6.5 as 7.1 replaces it very cleanly.

Additional Information

I’ve had some strange and not always reproducible problems installing other Dell update packages, usually drivers, on Server Core and Hyper-V whenever OMSA is not installed or is out-of-date. The one I remember most clearly was related to the Lifecycle Controller.

It’s NOT the Network, the Hypervisor, or the OS!

I’ll do my best to keep this posting on an even keel and not let it devolve into a rant, but no promises. As I poke around in various technical forums, whether LinkedIn or Spiceworks or TechNet or whatever, a new theme is popping up. People are complaining that they’ve dropped in a shiny new 10G network and just can’t figure out why it’s not any faster than their old 1GB network, or they’re using internal/private networks inside Hyper-V or ESX and they don’t go any faster than a standard copper line. In a couple of cases, I’ve actually taken the effort to try to explain what’s going on, but usually it falls on deaf ears. This post serves as both an explanation and an appeal to the more sensible administrators out there to look at what’s really going on.

Review of Veeam 6.0 for Hyper-V

Short-form: Too little, too late, too expensive. This product should only be of interest to mixed environments using Hyper-V and VMWare, and even those should strongly consider their options.
