Generic Trust Failure when install SCVMM 2012 SP1

Today I got a special problem I want to share with you. I tried to install SCVMM 2012 SP1 console on my Windows 7 VM to do some troubleshooting, but I get error message “Generic Trust Failure” when I click Install button in SCVMM 2012 SP1 installer, it mentioned something related to Microsoft Visual C++ 2010 x86 Redistributable.

I tried to run Microsoft Visual C++ 2010 x86 Redistributable installer from image folder directly, it show me exactly same error message. Nothing I found on google, but most posts pointed to signature.

After deep dive into the problem, I figured out a solution:

  1. Go to PrerequisitesVCRedisti386 folder of SCVMM 2012 SP1 image.
  2. Copy vcredist_x86.exe to local disk.
  3. Extract the executable file to a folder. (You have to install WinZip or something else to do that)
  4. Enter the extracted folder, right click Setup.exe.
  5. Select Properties.
  6. Go to Digital Signatures tab.
  7. Highlight the certification and click Details.
  8. Click View Certification button on pop-up window.
  9. Click Install Certificate button.
  10. Process the wizard by default option.

Troubleshooting of Microsoft product is much different with Linux, you have to dividing and conquering, deep dive into each elements of the product, read carefully of each logs, then you will find root cause.

Please let me know if you have better solution. :-)

How to configure nested Hyper-V VM on VMware Workstation

First, I would like to recommend DELL M4800 for small home lab, I spent lot of time to looking for a solution for my lab, I need some hardware low noise, low weight, and it is better portable. I checked out HP mini server, Apple MAC mini, Mac book pro…etc. They are nice products to show best design of IT industry, but no one perfect. Finally I choose DELL M4800. The reason is RAM can be upgraded to 32GB. 3 SSD hard disks is supported, you can install one native SSD, one in CD-ROM slot, another msata SSD in WAP slot. SSD disk is must have for IT LAB, it can provide you more than 10K IOPS without significant performance degrade.

Okay, back to topic…if you want to testing Windows Server 2012 R2 Hyper-V on lab, you probably prefer install it on a VM of VMware Workstation. You have to follow up proper steps to make sure the Hyper-V functionally.

After you create Hyper-V VM:

  1. Keep VM power off status.
  2. Go to Settings of VM.
  3. Highlight Processors.
  4. Select Virtualize Intel VT-x/EPT or AMD-V/RVI option.
  5. Go to Options tab.
  6. Highlight General.
  7. Select Microsoft Windows.
  8. Select Hyper-V on drop-list.
  9. Power on.
