Retrieving Packets Received Discarded Perfmon Counter From Multiple Servers

Posted on by Rhoderick Milne [MSFT]

Whilst working on a customer’s Exchange 2010 DAG issue, I wrote a quick script to quickly grab some performance monitor counters from all of their Exchange servers.  The issue that we were investigating was related to discarded packets when the VM was running on a certain hypervisor host.  The customer had moved their Exchange VMs to a new host and after doing so they were experiencing cluster iss… Read the rest “Retrieving Packets Received Discarded Perfmon Counter From Multiple Servers”

Hyper-V Could Not Initialize – Could Not Create or Access Saved State File

Posted on by Rhoderick Milne [MSFT]

As part of my relaxing holiday, I spent a fair bit of time upgrading the hardware in my lab and installing Windows Server 2012 R2 onto all of my Hyper-V hosts.  I then went through and pruned out some old test VMs and made sure the ones I had left were still relevant.

After I did the upgrade to 2012 R2 and powered on some machines that had been dormant for a few months, actually quite a few months … Read the rest “Hyper-V Could Not Initialize – Could Not Create or Access Saved State File”

Posted on by Rhoderick Milne [MSFT]

When I was running Windows 8 I ran into an issue importing VMs with the error “Did Not Find Virtual Machine To Import” and discussed it on the blog.   The presence on the .exp file was causing the import to fail.  Since I had to rebuild my corporate laptop, I hit a related the same thing in Windows 8.1 but with a different error message.

Importing the same set of lab VMs to Windows 8.1 gave me a di… Read the rest “Hyper-V Encountered An Error While Loading The Virtual Machine”

Posted on by Rhoderick Milne [MSFT]

One of the popular topics lately has revolved around the Hyper-V Did Not Find Virtual Machines To Import error.  This issue can arise when we try and import a VM into Windows Server 2012 R2 or 8.1 which was originally exported from Windows Server 2008 or 2008 R2.  Such exported VMs from 2008 or 2008 R2 use a .exp file to hold the exported VM's configuration.  The issue is discussed in detail in the… Read the rest “How To Import Windows 2008 R2 VM To Windows 2012 or 8.1 Using Boot To VHD”

A picture says a thousand words.   This is one of the reasons that the various architecture posters are so popular as they provide an easy way to visualise the Hyper-V stack.

Windows Hyper-V 2012 & 8.1 Hyper-V Did Not Find Virtual Machine to Import

Posted on by Rhoderick Milne [MSFT]

Back in May 2013, we discussed an issue which caused the Hyper-V Did Not Find Virtual Machines To Import error.  Well, as mentioned in that blog post there are a few reasons for this error message being displayed and it does depend on the versions of Hyper-V in use.

There were some comments posted (thanks again for that by the way!) which mentioned an issue with importing VMs into Windows Server 201… Read the rest “Windows Hyper-V 2012 & 8.1 Hyper-V Did Not Find Virtual Machine to Import”

Exchange And Hyper-V Replica Support

Posted on by Rhoderick Milne [MSFT]

After seeing several posts and some folks discussing whether or not Exchange supports the Hyper-V Replica feature I thought it would be prudent to address the following:

  • Does Exchange Support Hyper-V Replica?
  • Does Hyper-V Support Exchange?
  • How Do I use Exchange and Hyper-V Replica?

What Is Hyper-V Replica

For some background reading on Hyper-V and the Replica feature; the component poster and downloada… Read the rest “Exchange And Hyper-V Replica Support”

Updating Hyper-V Integration Components (IC)

Posted on by Rhoderick Milne [MSFT]

One of my favourite features in Windows 8 is client side Hyper-V.  This allows me to run multiple virtual machines on my Lenovo W530 laptop without having to remote to other machines when I am on site with customers.

As you can imagine I have a plethora of VMs for a variety of situations, and I ran into a bit of a pickle when moving my Exchange 2003/2007/2010 migration workshop lab over to Windows 8… Read the rest “Updating Hyper-V Integration Components (IC)”

Hyper-V Did Not Find Virtual Machine To Import

Posted on by Rhoderick Milne [MSFT]

Since I have this lovely Lenovo W530 laptop with a couple of disks and 32GB of RAM, it is great to run VMs on!  As you can imagine, I have multiple different Exchange labs to reflect all the different versions and builds that are in use.  Generally I have been able to import all of my older VMs into Hyper-V on Windows 8 and 2012 with no issues.  But as you probably have guessed by now, if I had no… Read the rest “Hyper-V Did Not Find Virtual Machine To Import”
