How To Use Altaro VM Backup for an Authoritative Restore

24 Sep 2015 by Eric Siron     0    

Things in Active Directory get deleted. Sometimes, it’s an accident (or maliciously done) and the object really shouldn’t have been deleted. Other times, something happens that causes great chunks of Active Directory to become corrupted. The oldest technique for dealing with these problems is called an “Authoritative Restore”. In the past, this process involved restoration of the System State of a domain controller. If your domain controllers are virtualized and you’re using a hypervisor-level backup tool like Altaro, you can’t perform just a System State restore. Fortunately, that’s not a problem at all.

How to Meter and Track Hyper-V Networking Performance with MRTG

How to Meter and Track Hyper-V Networking Performance with MRTG

16 Jul 2015 by Eric Siron     5    

Metering is one of those unpleasant yet essential parts of systems administration. If you don’t know anything about your systems’ resource utilization, you can’t properly design their replacements. If you haven’t been keeping track, you won’t be able to answer the question, “What happened” when things go awry. If you aren’t keeping a close eye, you won’t have any advance warning before something collapses in the middle of a major production cycle. When it comes to networking, you’re probably not going to believe how easy it is to get MRTG up and running.

How to run Ubuntu Linux Server as a Hyper-V Guest VM

Getting Started with Ubuntu Linux Server as a Hyper-V Guest

14 Jul 2015 by Eric Siron     13    

 Linux on Hyper-V is becoming more and more popular as Microsoft continues to increase their support for it. One of the nicest parts about it is the “It Just Works” aspect. For distributions that are less than a few years old, the Hyper-V Integration Components are built right in. There isn’t any time wasted fiddling with scouring the Internet to look for instructions on compiling or even scripting them in. For me, my interest was sharpened when my TechNet subscription expired for the last, non-renewable time. I could, and will, start using the evaluation copies of Windows Server for testing, but that expiration thing is pretty annoying. Sure, 120 days seems like a long time. Maybe for people in their 20s, it is. But, as I was working up my Linux examples, I noticed that I hadn’t even rebooted my test lab switch in about seven months. If you’d asked… Read More»

Building a better VMM_8 ideas

Building a Better VMM: 8 Ideas

16 Jun 2015 by Eric Siron     6    

 One day, I was out traversing the wide, untamed world of my Twitter feed when I came across this most lovely post by Aidan Finn that does a great job summarizing Hyper-V’s Biggest Weakness. That post is required reading for this one. Actually, that post should be required reading for anyone that has anything to do with Hyper-V. Start there, then come back here. Aidan’s post is about the state of management tools for Hyper-V in general. I’m going to focus on System Center Virtual Machine Manager (VMM). Even if you don’t use VMM, this article is for you. If you have Hyper-V but not VMM, then that is something that Microsoft seriously needs to address whether you (or they) realize it or not. I believe that there should be a set of free tools with a premium management pack. The free tools should be enough for anyone to get… Read More»

42 Best Practices Balanced Hyper-V Systems

42 Best Practices for Balanced Hyper-V Systems

10 Mar 2015 by Eric Siron     5    

 Last year, Nirmal Sharma wrote a fantastic article on this blog titled 23 Best Practices to improve Hyper-V and VM Performance. This sparked up a very lively discussion in the comments section; some were very strongly in favor of some items, some very strongly opposed to others. What I think was perhaps missed in some of these comments was that, as Nirmal stated in the title, his list was specifically “to improve Hyper-V and VM performance.” If squeezing every last drop of horsepower out of your Hyper-V host is your goal, then it’s pretty hard to find any serious flaws with his list.

Strategies for Hyper-V Dynamic Memory

Deep Strategies for Hyper-V Dynamic Memory

26 Feb 2015 by Eric Siron     2    

 Dynamic Memory is one of Hyper-V’s most misunderstood and underutilized technologies. Many people believe that it’s not working when it’s doing exactly what it’s supposed to. Too many won’t use it at all based on incorrect assumptions. Most don’t understand the conditions in which it will operate. Unfortunately, there’s really not a simple guide to using it properly, or you’d find articles on it everywhere. If you want to squeeze the most out of your virtual environment, you’re going to need to get your hands dirty with some of the grease that’s down in the guts of your systems

Troubleshooting Adapter Teaming in Hyper-V Server

Troubleshooting Adapter Teaming in Hyper-V Server

19 Feb 2015 by Eric Siron     0    

 Native adapter teaming is a hot topic in the world of Hyper-V. It’s certainly nice for Windows Server as well, but the ability to spread out traffic for multiple virtual machines is practically a necessity. Unfortunately, there is a still a lot of misunderstanding out there about the technology and how to get it working correctly.

Hyper-V and PowerShell: Splatting and Profiles

Hyper-V and PowerShell: Splatting and Profiles

17 Feb 2015 by Eric Siron     0    

 In the first article of the Hyper-V and PowerShell series, we talked about using tab completion to ease the typing burden. There are other tricks that can reduce it even further. Of those, I’m going to illustrate splatting and profiles. Of the two, I usually get much more mileage out of profiles. However, I’m going to introduce splatting first as it will explain some of the things I do with my profile. If you’re someone who does use PowerShell but does not write script files, splatting may not seem like something that can be of use to you. Nothing could be farther from the truth.

Microsoft Server Licensing in a Virtual Environment Revisited

Microsoft Server Licensing in a Virtual Environment Revisited

12 Feb 2015 by Eric Siron     6    

 Late last year, we published an eBook about licensing Microsoft server operating systems in a virtual environment. This was followed up with a webinar by Thomas Maurer and Andrew Syrewicze. Toward the end of that session, they took some questions. Since then, we’ve received a few more. We’ll use this article to answer those questions and to further expand on some of the ideas in the eBook.

Multiple Hyper-V Virtual Switches

Explored: Using Multiple Hyper-V Virtual Switches

29 Jan 2015 by Eric Siron     0    

 In our article on common Hyper-V deployment mistakes, one item we discussed was the creation of too many Hyper-V virtual switches. This article will expand on that thought and cover various Hyper-V virtual switch deployment scenarios. One Switch will Usually Suffice The first and most important point to make is the same as mentioned in the earlier article: one virtual switch is enough for most Hyper-V hosts. We’ll start by showing how advancements in Windows and Hyper-V technologies address problems that necessitated multiple virtual switches in earlier versions. Native OS Teaming is Now Available In 2008 R2 and earlier, you could only team network adapters by using software provided by the network card manufacturer. This software was often buggy and unstable. Furthermore, Microsoft would not officially support any system that used such teaming. In those situations, Hyper-V administrators would often choose to leave the physical adapters unteamed and create multiple… Read More»

TCP/IP Routing in a Hyper-V Guest

How to Install and Configure TCP/IP Routing in a Hyper-V Guest

27 Jan 2015 by Eric Siron     6    

 One of the great things about the Hyper-V virtual switch is that it can be used to very effectively isolate your virtual machines from the physical network. This grants them a layer of protection that’s nearly unparalleled. Like any security measure, this can be a double-edged sword. Oftentimes, these isolated guests still need some measure of access to the outside world, or they at least need to have access to a system that can perform such access on their behalf. There are a few ways to facilitate this sort of connection. The biggest buzzword-friendly solution today is network virtualization, but that currently requires additional software (usually System Center VMM) and a not-unsubstantial degree of additional know-how. For most small, and even many medium-sized organizations, this is an unwelcome burden not only in terms of financial expense, but also in training/education and maintenance. A simpler solution that’s more suited to smaller… Read More»

Hyper-V- in Server 10

Looking Forward to Hyper-V in Server 10

06 Jan 2015 by Eric Siron     0    

 New year, new products! Some time in 2015, we’re all going to be graced with the newest edition of Windows and Windows Server, and along with them, Hyper-V. I wish I had a slick code name to give you, like “Viridian”, but it seems like most in-progress Microsoft products are now just code-named “vNext”. I’ve spent some time going over the published feature list. Some of the introductions will be very welcome. Some make me a bit less than enthusiastic. Sole Sourcing I’ve been burned more than once by writing about pre-release features and software conditions, even within a few months of release. The next version of Hyper-V is still quite a ways away, so there is still time for significant change. To that end, I’m only going to work with the officially published material on Hyper-V. Even that material could still be considered malleable at this point, but, in… Read More»

The Time for Hyper-V Pass-Through Disks has Passed

The Time for Hyper-V Pass-Through Disks has Passed

01 Jan 2015 by Eric Siron     0    

 Hyper-V is no longer the newcomer in the virtualization space. After springing forth from its Virtual Server parent, it’s now had over half a decade to mature into the reliable, enterprise-grade hypervisor that it is today. As with any complex software, Hyper-V is composed of many parts, like the branches and leaves of a great tree. Like a tree, some of those branches form into major trunks that define the tree’s silhouette. Others become a twisted impediment to the proper growth of the larger organism and must be pruned away for its overall well-being. In Hyper-V, one of those latter branches is the pass-through disk. Many of you are already aware of this fact and have long since moved on. The reasoning behind this post is that there are still a handful of people out there clinging to this old tech, wishing that branches that were solid in 2008 weren’t… Read More»

Hyper-V and Powershell: VM Process

Hyper-V and PowerShell: VM Process

30 Dec 2014 by Eric Siron     0    

 In the article that contains the Restart-VM script, I mentioned that a VM that can’t be stopped with Stop-VM requires you to kill its VMWP process. It might not be obvious how to determine which process that is. I’ve written a script to help you do that. This article is part of the “Hyper-V and PowerShell” series. This script is extremely straightforward so it doesn’t require a lot of explanation. I opted to only allow you to input a single VM name at a time. If you use the pipeline, it will run once for each input object as normal. As with the Restart-VM script, I designed this one as a function that must be dot-sourced. Please read that article for directions. Parameters There are only three parameters: Name, ComputerName, and VM. Name: The name of the virtual machine whose process you wish to retrieve. Cannot be used with VM.… Read More»

The Hyper-V Portal 2014 Year in Review

The Hyper-V Hub 2014 Year in Review

23 Dec 2014 by Eric Siron     0    

 Like any creative work, a blog post is never really done; it’s just abandoned. Unlike many other mediums, blogs do allow us to easily refresh those older articles, but we so rarely ever do it. To close out this year, a few of us on the editorial team got together and selected a few highlights from the past year. Our 14 selections from 2014 (in no particular order): Hyper-V Guest Licensing This was our first licensing article directly related to guest licensing. We followed it up with a downloadable eBook that was expanded to include a number of examples, and Andy Syrewicze and Thomas Maurer gave a fantastic webinar on the topic. We’ve received quite a few questions and some great feedback. Keep an eye out for a follow-up post that takes on some of those questions and incorporates some of the suggestions. If you’ve got questions or suggestions of… Read More»
