Microsoft Hyper-V S3 Cap warning when upgrading a Hyper-V Virtual Machine

Posted on by

When you do an in place upgrade of a Hyper-V virtual machine you’ll get a warning that Microsoft Hyper-V S3 Cap may not work after the upgrade and that you need to update the driver prior to the upgrade.This warning is logged to the Windows Compatibility Report.htm.

Microsoft Hyper-V S3 Cap is an old S3 Trio 765 emulated video device and the driver isn’t included anymore so you’ll get this particular warning. This will never give you an issues, all drivers needed are indeed in the install bits. You can safely ignore this and successfully upgrade.

Some people uninstall the device via device manager but basically that’s pure cosmetics & doesn’t really serve a purpose.

This warning is an artifact of the generation 1 virtual machines who still have this device on a PCI bus.  Below is a screenshot of a VM with W2K12R2, generation 1. As you can see the Microsoft Hyper-V S3 Cap is perfectly fine. No worries.image

As a matter of fact you will not even see this device on a generation 2 virtual machine and we should not see this with an upgrade of those.

I will have to wait on a public preview of Windows vNext to test an upgrade of a generation 2 machine to prove my thinking that this cosmetic error won’t be there anymore.

First we take Redmond, then we take Berlin & Ede: Summits & Conferences

The traveling & speaking MVP

MVPs are a busy lot. They work, learn, travel & talk a lot. Why to share knowledge & experiences for the benefit of all. So in order to keep that reputation going I’ll be heading to SEATAC to attend the Global MVP Summit 2014 in Bellevue/Redmond. After that tech fest I return to Belgium where I’ll immediately head towards Berlin to present at the Microsoft Technical Summit 2014. After a weekend of rest I head north to The Netherlands to present at Experts Live.

No rest for the wicked. There is a a tremendous amount of things happening in IT right now. It takes a little bit of effort to keep up an asses the benefits and value butt once you’re doing that as part of your normal day to day operations it becomes a lot easier to map out  why it’s useful to you and what to use where, when and how.

All this is happening at a time that the information on “Treshold” or Windows vNext is becoming available if we can believe the rumors and the buzz on the internet. Don’t forget that TechEd Europe 2014 is on in the last week of October in Barcelona right before the MVP Summit in Redmond. Like Aidan Finn said, we could go on a 3 month presenting, training & consulting tour right now as the need for insights & skills is growing with the growth in Hyper-V adoption and with that all related technologies from networking, storage to Azure.

Now I can’t invite you to the MVP Summit but I can do that for both the Microsoft Technical Summit 2014 and Experts Live. There will be a lot of international expertise at both events who have hands on expertise with the technology in real life production environments. I always pick up knowledge form them myself.

The Global MVP Summit 2014

Every MVP on this planet tries to make it to the MVP Summit. The face time with and access to so many intelligent people at MSFT is invaluable. Combine that with the opportunity to network experts form all over the globe and you realize why we spend the time effort and money to attend.

747-BA-02

So once more we hop on that great Boeing 747 and let BA fly us to SEA-TAC airport from where we’ll head to Bellevue/Redmond as the summit is spread between both locations.

The MVP is NDA. So there will be tweets about the fun stuff with fellow MVPs but other than that we’ll be going dark. We have never and will never breach NDA. We’ll also make some time to meet up with old acquaintances, friends and fellow Belgians living & working around Seattle/Bellevue/Redmond.

Microsoft Technical Summit 2014

The moment I get back home I grab a change of clothes & a flight to Berlin.

The Microsoft Technical Summit 2014 is on in Berlin and together with a great number of fellow MVPs I have the distinct pleasure of presenting What’s new in Failover Clustering (Windows 2012 R2).

It’s amazing to see how many of our community experts are actually from Germany, Austria & Switzerland (DACH) and I’ll be happy so see so many familiar faces I just saw on the other side of the big pond just a week before Smile

Experts Live 2014

On November 18th I’ll be in The Netherlands at Experts Live 2014 in Ede. This is a great event and if you know the brain power of the organizers & presenters this is no surprise. I’ll be presenting “The Capable & Scalable Cloud OS “ and showing some of the scalable capabilities in Windows Server 2012 R2 when combined with great hardware. image

So that’s the travelling & scheduling agenda for now. Perhaps I’ll see you at one of those events & if you’re a reader of this blog ping us if you’ll be there for a meet and great. Live is good Smile.

Online Resizing Of Hyper-V Virtual Disks Is Possible in Windows 2012 R2

Posted on by

Windows Server 2012 R2 brought us the ability to resize virtual disks on line. This was a long sought after feature for many of us. It can be done via the GUI or with PowerShell. I do note however that quite often people have some problems when first using this capability. So we’ll go over the rules & prerequisites here.

Listed below are the important factors to keep in mind

  1. It has to be a VHDX
  2. Works for both generation 1 and generation 2 virtual machines
  3. It needs to be attached to a vSCSI controller. Remember this when dealing with with generation 1 virtual machines. In particular note that this means you cannot live resize the system disk as that IDE only (can’t boot from SCSI in generation 1).
  4. The virtual disk cannot be a shared VDHX (it’s on my feature request list for vNext)
  5. You can extend a virtual disk
  6. You can shrink a virtual disk
  7. This feature can leverage ODX for speed when available. The speed of this is quite addictive.

Some notes where people seem to make some other mistakes

You’ll note that you cannot shrink a virtual disk that has no unallocated disk space on the disk inside the virtual machine. When you see this picture inside of the virtual machines you can shrink your VHDX if all the above factors are in order.image

image

If there is no unallocated disk space the option to shrink the VHDX won’t even show up in the GUI.

image

This means you’ll first need to shrink the volume inside the virtual machine if all disk space has already been allocated.

image

(Like wise don’t forget to expand the volume inside the VM to be able to use the added space you see show up as unallocated space on the disk.)

The below image is a great summary of the above

Legacy OS in the VM?

It’s also important to note that an OS inside a VM (Windows Server 2003 comes to mind) that does not allow the expansion or shrinking of volumes means you will need a 3rd party tool to do the same. I use GParted, a free partition editor for these scenarios.

Looking Back at the DELL CIO Executive Summit 2014

Yesterday I attended the DELL CIO Executive Summit 2014 in Brussels. Basically it was home match for me (yes that happens) and I consider it a compliment that I have been given the opportunity to be invited to a day of C level discussions.

Apart from a great networking opportunity with our peers we had direct access to many of DELL’s executives. I found it interesting to see what some existing customers had to say and share about their experiences with DELL Services. Especially in the security side of things where they provide a level of expertise and assistance I did not yet realize they did.

The format was small scale and encouraged interactive discussions. That succeeded quite well and made for good interaction between the attending CIOs an DELL executives. We were not being sold to or killed by PowerPoint. Instead we engaged in very open discussions on our challenges and opportunities while providing feedback. It reminded me of the great interaction promoting format at the DELL Enterprise Forum 2014 in Frankfurt this year. You learn a lot from each other and how others deal with the opportunities that arise.

To give you an idea about the amount of access we got consider the following. Where can you walk up to the CEO of a +/- 24 Billion $ company and provide him some feedback on what you like and don’t like about the company he founded? Even better you get a direct, no nonsense answer which explains why and where.  Does he need to do this? My guess is not, but he does and I appreciate that as an IT Professional, Microsoft MVP and customer.

Before the CIO Executive Summit started I joined the Solutions Summit, to go talk shop with sponsors/partners like Intel and Microsoft, DELL employees & peers and lay my eyes on some generation 13 hardware for the 1st time in real life.

It was a long but very good day. As the question gets asked every now and then as to why I attend such summits and events, I can only say that it’s highly interesting to talk to your peers, vendors, engineers and executives. It prevents tunnel vision & acting in your village without knowledge of the world around you. Keeping your situational awareness in IT and business requires you to put in the effort and is highly advisable. It’s as important as a map, reconnaissance and intelligence to the military, without it you’re acting on a playing field you don’t even see let alone understand.
