Hyper-V

Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.

Andy's VMware vSphere tip#7: SNAPSHOTS (Hyper-V calls them Checkpoints!) Believe it or not one of EE most asked questions in the VMware Topic area, at least one question a week is asked in the VMware Topic, and the response by many VMware Administrators, is "my datastore has filled up, my VM has stopped working, and says retry or abort - I've checked and there are no snapshots reported in Snapshot Manager!"

I'll tell you it It lies to you.... quickly check VM Folder on the datastore, if you see a file -0000x.vmdk - the likelihood is you have a snapshot!

and guess what I wrote an EE Article here

http://www.experts-exchange.com/Software/VMWare/A_10300.html

If you use a backup product which is vSphere aware, it will use the Storage API - Snapshot method to backup your VMs, and most often leaves the VM running on a snapshot, and you are not aware.

CHECK DAILY FOR SNAPSHOTS as part of your VMware Daily Admin either manually, write a script, set a vCenter Server Alarm.

or use Snapwatcher by Opvizor - see here https://try.opvizor.com/snapwatcher/

Catch your VM snapshots before they catch YOU!

If you find yourself with a snapshot issue, out of your depth STOP! do not ignore it Ask for help on EE in the VMware Topic area, it's serious, and corruption can occur if not dealt with promptly and correctly.

Have a Good Weekend...

Cloud Class® Course: C++ 11 Fundamentals

This course will introduce you to C++ 11 and teach you about syntax fundamentals.

Andy's VMware vSphere tip#4: Partitions :- OS Partitions have no place in VMware vSphere or Hyper-V. So do not create a C: Partition or volume, and D: Partition or volume on the same virtual disk. We used partitions in the dark old ages of DOS, when the limits of a partition were 32MB, so we had to create multiple partitions on our disks, to use all the disk space.

Keep a single partition per virtual disk. e.g. create a single virtual disk for C:, if you need a D; create another virtual disk.

You will thank me in the future, because it becomes much easier to expand C: and D:, if they are on separate virtual disks. You've also got the benefit of being able to specify which datastore, these will be hosted on which is important if you have tiered storage for performance.

So in Summary do not create partitions, C: D: E: F: on the same virtual disk, you will regret it, later and then you will have to use VMware Converter, to convert your machine and remedy the situation.

Please feel free to post a question to the VMware or Virtualization topic areas to discuss this further.

It may go away on new machines, but still will be with us a long time to come...

EE questions still being asked about Windows 2000 and Windows 2003

Yes, older machines will have BIOS, but new ones just UEFI and Windows 10  (or Server 2016 and beyond)

Still, we are on the same page :)

Is there a known well tested functional SDK or API to query Hyper V guests OSs performace counters such as cpu usage, core usage, memory ? I know for example that VMware has its own SDK for that so I need similar.

We have a HP ML310 Gen8 V2 that had Server 2012 Essentials (not R2). We are trying to rebuild the server to Hyper-V core 2016.

Once 2016 core has been installed and we create the VM, mount the Server 2012 Essentials ISO we press any key to boot into the CD/DVD afterwards when we are presented with the Server installation screen (language/product key etc). the mouse works fine, however the keyboard doesn't.

We have tried enabling the guest services, reinstalled with Server 2012 R2 core instead of 2016 with the same issue. If we try another ISO such as Server 2016/Windows 10 on the VM it works perfectly fine. So I assumed it was the Server 2012 Essentials media, so we obtained some more with the same issues.

If we boot directly to the Server 2012 Essentials DVD doing a physical install, everything works as normal, however we would like to virtualise this server. We also had to disable VT-D in the bios in order for it to boot the 2016 Core as per https://community.hpe.com/t5/ProLiant-Servers-ML-DL-SL/ML310e-Gen8-V2-with-Server-2016-Hyper-V/td-p/6912878

Hyper-V 2016 Trouble...  
HVMMC errorPSSession errorI have two 2012 r2 VM DCs running on a standalone Hyper-V 2016 host.  I set up remote management VIA PowerShell and Hyper-V Management console. I guess over WINRM with CredSSP.  Well everything was working fine (6-8 months or so now).  I all stopped a few weeks ago. I tried to pin it down to a security update but could not.  When I try to start a new PSSession or authenticate on the HVMMC I get an HTTP error code 403.  Everything I have found so far seems to be related to exchange and IIS,  neither of which are on these VM and the host is just Hyper-V it can't run anything else.  Also at the same time I could no longer check point my VM's which is required to work for my Unitrends recovery appliance.  It's like the entire management subsystem is broken.   I am still able to RDP into the host and manage the VMs with PowerShell but that's it...  I looked through application and error logs.  But I didn't see anything that appeared relevant to me...
