Microsoft – Preparing for free exam 74-409 Server Virtualization with Windows Server Hyper-V and System Center

Exam dumps

Unfortunately I’ve received numerous requests for an exam dump of 74-409 which really upsets me.

For those that are not aware of it, you are not allowed to share or use exam dumps. “If Microsoft learns that a candidate used a “brain dump” site to prepare for an exam, this candidate will be permanently banned or prohibited from taking any future Microsoft Certification exams and may be decertified from the Microsoft Certification Program. In addition, test scores and certifications, if applicable, may be revoked. These actions may be taken even if the candidate did not intend to defraud the Microsoft Certification Program.”

For more information, see:

Preparing to take the exam

This is generally what I do for preparing to take the exam:

  1. Determine the skills that are measured in the exam 74-409
  2. View the online course Server Virtualization with Windows Hyper-V and System Center at Microsoft Virtual Academy (MVA)
  3. Reflect how confident you are that the online course has provided you with sufficient skills to take the exam.
  4. Optionally enhance your knowledge using:

Specific topics and resources I used while studying:

Microsoft – Recordings for “Using Microsoft VDI to Enable New Workstyles Jump Start” available on MVA

The recordings for “Using Microsoft VDI to Enable New Workstyles Jump Start” are available now on Microsoft Virtual Academy (MVA).

These Jump Starts are a great way to quickly get up-to-date about a subject. Also there’s a great team of people working behind the scenes to answer questions and provide more detailed resources. Other attendees often also share their experiences and provide valuable insights. So be sure to check out the Q&A log as well.

Microsoft – Free Windows Azure for IT Professionals Jump Start

Microsoft Virtual Academy (MVA) is hosting the “Windows Azure for IT Professionals Jump Start” at May 16th. Information and registration is available on the website: https://www.microsoftvirtualacademy.com/liveevents/Windows-Azure-for-IT-Professionals?CR_CC=200206715

I’ve attended a couple of Jump Starts and I think it’s a great way to quickly get up-to-date about a subject. Also there’s a great team of people working behind the scenes to answer questions and provide more detailed resources. Other attendees often also share their experiences and provide valuable insights.

Also it’s only been a couple of weeks since Windows Azure IaaS is live in production backed by an enterprise SLA, supported by Microsoft Support, and ready for your production applications. Therefore it is a great time to start learning more about it.

I hope to see you there.

Intel Haswell CPU available in June with VMCS shadowing – nested virtualization

In the beginning of June, the new Intel Haswell CPUs will be available. Besides the regular improvements like being faster, having better energy efficiency and having better graphics capabilities, these new CPUs will also include VMCS shadowing (Virtual Machine Control Structure Shadowing).

Basically it’s a feature that allows you to run a hypervisor (like VMware, Hyper-V, Xen Server) and create another hypervisor as a VM beneath it. This is also called nested virtualization.

Some of you might say, “Hey this is not new, I’ve already done this with VMware!”. The difference however is that the current method uses some sort of emulation that does not directly access the hardware. And even though it’s great for testing purposes, the performance is suboptimal.

With the embedded hardware supported VMCS shadowing in the new Intel Haswell CPU the nested hypervisor can directly access the hardware, which should improve performance. Also, it might even make it possible to use non-VMware hypervisors in a nested virtualization scenario.

Of course as always, we’ll just have to wait and see how the performance will be in real-life. It’s also not clear to me yet if hypervisors need to be updated to be able to leverage this option. Nonetheless, to me it sounds very promising and I look forward to playing around with it.

For more information read this great article by Gabe Knuth called “Could VMCS Shadowing (a.k.a. nested VMs) from Intel’s new Haswell processors be what Bromium needs to work in VMs?”. When you use the links in the article you will be able to get more information about the Intel Haswell CPUs including benchmarks and more detailed information about VMCS shadowing and use cases.

[EDIT 08-06-2013] Citrix is working hard on integrating VMCS Shadowing / Nested VMs in their products:

If you’re planning to build / buy an Intel Haswell based computer or Home Lab, be sure to look into the confirmed USB3 bug in the chipset. Also unfortunately the DDR3 prices have increased substantially (almost 50%) over the last half year.

Microsoft – Windows Server 2012 Hyper-V 3.0 best practices checklist

Roger Osborne has posted a great article with a Windows Server 2012 Hyper-V best practices checklist.

I especially like the fact that it’s not just a checklist, but it also explains what it does and why it is considered a best practice to do it this way (in specific situations).

Additionally you might also want to take a look at “Top 20 Hyper-V Performance Metrics You Should Care About” and System Center Advisor.

Microsoft – Introduction to Hyper-V Jump Start videos and Q&A transcript

The videos of the “Introduction to Hyper-V Jump Start” have been posted to Microsoft Virtual Academy:
https://www.microsoftvirtualacademy.com/tracks/introduction-to-hyper-v-jump-start

Unfortunately however, the link to the Q&A transcript has only been sent by mail to participants. The Q&A has very valuable information in it as well, so be sure to take a look at it here.

[EDIT] I mailed the MVA people and they added the Q&A to the MVA website as well. Love the MVA [EDIT]
