Backing up your virtual machine

When you’re making a recovery plan and back-up of your virtual environment, you should take into consideration the various factors that may interfere with your back-up such as: the state of the virtual machine at the time you made the back-up (system state, shut down, running) and the type of storage you use for these back-ups.

The integration of the support service with the Volume Shadow Copy service of Hyper-V allows you to make a back-up of both the virtual machine as well as the Hyper-V configuration. There are two basic methods you can use for this type of back-up:

1. Make a back-up copy from inside of the operating system of a virtual machine. This method is useful when you need to save data from a storage device that is not supported by Hyper-V VSS.

2. Make a back-up from the Hyper-V server. This is the most recommended method for making a complete back-up of the server because it captures more data than the first method. If the storage device is compatible with Hyper-V and Hyper-V VSS, you can make a complete back-up of the server that will help protect all the data required to re-install the server in case of failure.… Read More

Videos on the new version of Hyper V and Hyper V Server

It seems as though virtualization never ceases to be in the news. Today, I have some videos on the new version of Windows 2008 Hyper V, which will be available with the launch of Windows Server 2008 R2, whose latest feature (and criticism) is changing cluster nodes without losing power. Also called “Live Migration”, this is a significant improvement of “Quick Migration”, which directed the virtual machine to the live node but restarted it. It’s quite interesting to see how an end user sees no interruption in service during the movement of virtual machines between nodes when using Live Migration which is going to be the replacement for quick migration. Check out the Video below to see Live migration in action & check out Hyper-V Live migration vs Quick migration post to find out more about the difference between them .

Another good video of Live migration can be seen below:

I also have a video on Hyper V Server, a version of Windows Server 2008 that only includes the Hyper V role. What are the benefits? It’s completely free. What about the disadvantages? You cannot cluster as a service (the virtualized machine itself can be part of a cluster). It will be available in a month or so.… Read More

Microsoft vs. VMware: Companies lose the battle – Part 2

Signs of an immature market

But is it really necessary for hypervisors to be a proprietary technology? Efforts by Microsoft and VMware to differentiate their hypervisors remind us of the networking situation thirty years ago, when all power suppliers believed in different technologies (Token Ring, Ethernet, ARCNET, etc.). Gradually, however, manufacturers have accepted the idea that taking a common standard (TCP/IP over Ethernet) and concentrating their efforts on innovation in the upper levels of the software stack, stimulates the growth of the market as a whole and, consequently, the value of the manufacturer’s own share of the pie. It seems that in the case of virtualization, suppliers are not yet ready to see the situation from this perspective. Today, speeches still revolve around concepts such as speed and feeds, but probably the market itself will finish by imposing its own rules.

If all server-based computers are in the early stages of a massive migration towards virtual machines, as many analysts argue, the lack of a standard hypervisor for Windows will only delay this transition. The fact that manufacturers focus on being different and unique shows that virtualization is still an immature business. The problem is that, despite this immaturity, many companies are already dependent on virtualization.… Read More

Microsoft vs. VMware: Companies lose the battle – Part 1

Microsoft has just released Hyper-V, its new hypervisor software that will be the foundation of virtualization on Windows Server 2008. This release will force VMware to finally confront a dangerous opponent in the market of virtualization of Windows servers. Unfortunately, Microsoft has decided to follow in the footsteps of VMware by choosing their own unique way of doing things, and VMware also refuses to cooperate. The result: IT departments are faced with the need to choose between two mutually incompatible virtualization options.

Virtualization is based on a fine code, called hypervisor, which is located on the hardware and abstracted from the Windows virtual servers running on the upper level. The primary purpose of hypervisors is to redirect requests between multiple virtual machines and the original hardware, so that each VM believes that the hardware is its own.

Many foresaw that the hypervisor would evolve into a standard commodity and that the innovations by which suppliers would differentiate themselves would occur at the software level. However, that is not what has happened. On the contrary, the struggle for this market resembles a battle between Titans, in which two major manufacturers—practically monopolies in their respective markets—are battling it out with their designs.

In any case, it looks like the market is leaning towards VMware.… Read More

Hyper-V: A new breed of SID

If you already know what tokens, SIDs and DACLs are, skip ahead and go directly to the first image below.

Ever since Windows NT, the basic principle of Windows security, (i.e. Discretionary Access Control) uses SID and ACL (access control list). For a more detailed explanation, I recommend that you read Chapter 8 of the book “Windows Internals” by Mark Russinovich and David Solomon. Another good reference is the chapter on Authorization and Access Control Technologies of the Windows Server 2003 technical library.

For a quick explanation, I will try and put it in abstract terms: in Windows, all processes are authenticated and run in the user’s security context. A token is attached to each process, and this token contains, among others, the user’s IDs and all of the groups to which the user belongs. If you run the command whoami/all in a command line, you get a clear and readable view of your token. Because users and groups can change their names, they are located digitally with security IDs (Security Identifiers). Windows will usually do the translation for you.

Objects such as files have a Security Descriptor (SD), which contains a DACL (Discretionary Access Control List). This list contains ACE (Access Control Entries) and each ACE identifies an SID and an access type.Read More

Windows Server 2008 Hyper-V Release Candidate! …

Microsoft has spent an important steps in virtualization since it has announced the Release Candidate version of its a long waited Hyper-V. Already present in Windows 2008 Server Beta, this update (RC 0) Install on 2008 can see, a little more prepared for the final version that is evolving over time. Thus, Microsoft intends to take a sector already acquired by VMWare. Microsoft hopes to convince businesses to choose their virtualization solution, by partnering with large companies like Dell, AMD, Siemens, Intel, IBM… to improve the stability of its programs in all types of enviornments.

Microsoft has just announced a list of operating systems described as compatible and tested on Hyper-V which now includes Windows Server 2003 Service Pack 2 (SP2), Novell SUSE Linux Enterprise Server 10, Windows Vista SP1 and Windows XP SP3.

Install SUSE Linux Enterprise 10 SP1 & Component Integration for Linux on Hyper-V

In this article, I am planning to cover how to Install SUSE Linux Enterprise 10 on Hyper-V, but what make it different than other articles that I will try to cover how to install the Hyper-V Component Integration for Linux as well Inject the Xen Hyper-Visor into the SUSE Linux Enterprise 10 which is running as a guest OS to try to show how to unleash the claimed performance of Linux on Hyper-V.

The reason behind me writing this article is that I came across many articles who show you how to install Hyper-V. Then many others which show how to install Linux as a guest OS on hyper-V, but I have not seen any that show you how to do the full install of Linux on hyper-V to include the Linux Component Integration for Hyper-V and Xen Hypervisor. In addition, I have came across many other articles which mention that being not easy such as Fedore Core 8 on Hyper-V not so easy as it seems and MS Hyper-V vs VMware VI3 , but they still have not mention how to do it to let us figure out how hard its. So I decided to try it out and post my experience and try to prove the opposite if possible, but If you want to head to the last few lines to find out the conclusion before going over the full article “yes, its not as easy as I thought Microsoft product would run.”… Read More
