Virtual Machine could not be started because the hypervisor is not running

Hi
I have installed Windows Server 2012 Standard Edition with a GUI. Default configuration, nothing special.
Whenever I want to turn on any machine inside of Hyper-V, the following error message appears:
"Virtual Machine could not be started because the hypervisor is not running"
Whenever this happens, I run the following command:
bcdedit /set hypervisorlaunchtype Auto
and reboot the Server. After a reboot, all Virtual Machines can be started without Problems. However, as soon as I shut down the Server instead of rebooting it, the Problem happens again and I need to enter the command again and reboot.
Now my question is how to solve this Problem. I never had this Issue with Windows Server 2008 R2, maybe there are some differences regarding the Hypervisor in Server 2012. How can I make sure the Hypervisor is always on, even after a Shutdown? Thanks in
Advance

Hi,
Please check whether you have event log with ID 3112.
Hyper-V requires hardware support, including: an x64 CPU; VT (Intel) or AMD-V (AMD) hardware extensions; No eXecute (NX)/eXecute Disable (XD) and full BIOS support for hardware virtualization.
Check if the computer meets the hardware requirements, use the appropriate utility for your CPU manufacturer.
If the computer meets the requirements for Microsoft virtualization software, see the video titled
Hypervisor is not running error: How to fix
, which demonstrates how to change the system BIOS on a computer to enable support for virtualization. Make sure DEP and CPU virtualization is enabled in BIOS. (http://go.microsoft.com/fwlink/?LinkId=163578
Also, check that
Boot Configuration Data (BCD) store is set to start the hypervisor, and then restart your physical computer.
The BCD store contains boot configuration parameters and controls how the operating system is started in Windows Vista and Windows Server 2008 operating systems. These parameters were previously in the Boot.ini file (in BIOS-based operating
systems) or in the nonvolatile RAM (NVRAM) entries (in Extensible Firmware Interface-based operating systems).
You can use the Bcdedit.exe command-line tool to update BCD store with the correct launch options as referenced in the error, and then restart the server. Bcdedit.exe is located in the \Windows\System32 directory by default.

Win8 Pro Hyper-V Error : Virtual machine could not be started because the hypervisor is not running

Hello,
Recently in Dec I bought a new desktop PC.
HP ENVY Desktop h8-1420t
CPU & ChipSet: Intel Core i7 Intel Z75
I have Windows 8 Pro and installed Hyper V but cannot start the virtual machines. I get the following error message: Virtual machine 'zzzz' could not be started because the hypervisor is not running
I followed these steps to enable Hyper-V:
1. Upgraded to Windows 8 Pro
2. Tried to add Hyper-V feature but Hyper-V Platform was grayed out
3. Enabled Virtualization in the BIOS - security configuarion
4. Cold booted Computer
5. Added the Hyper-V Platform Feature
6. During the restart machine was in forever state spinnign state, did a manual reboot
7. Disabled Virtualization in the BIOS again
8. Successfully Re-Booted the Computer now Hyper V manager was available
9. Configured Hyper V network to use external network
10. Created a new VM through the Hyper-V Manager
12. Tried to boot up teh newly Created VM and I get this error message:
Virtual machine 'zzzz' could not be started because the hypervisor is not running
Any solutions for the error I am seeing above?

Same Problem Here - did you discover any answers? I may have to return the system if it can't do hyper-v

Virtual Machine '' could not be started because the hypervisor is not running (10041)

I'm unable to start any VM from hyper-v. This includes the various emulators (windows phone 8 and android).
I'm dual booting windows 10 with windows 8.1 and I can run the vms in the windows 8.1 without any issues at all. I checked the services running and of all the hyper-v services I could identify, only "Hyper-V Virtual Machine Management" is running.
How do I fix this? Below is the result from running coreinfo:

Good morning
I have the same problem as here, every moning i must writing pasword.

But my configuration is the same as was answer in this post, may be you can help me with another idea?. Thanks.

Both machines start with an automatic login so technically there is an interactive user.
Nevertheless, it is an interesting point. i will try to configure the applications to run under a particular user and see if that changes anything.

Error Message: "Skype can not start because the system is not available"

Try to reset all Skype settings. Quit Skype or use Windows Task Manager to kill any Skype.exe process. Go to Windows Start and in the Search/Run box type %appdata% and then press Enter or click the OK button. The Windows File Explorer will pop up. There locate a folder named “Skype”. Rename this folder to something different, e.g. Skype_old. Next go to Windows Start and in the Search/Run box type %temp%\skype and then press Enter or click the OK button. Delete the DbTemp folder. Restart Skype. N.B. If needed, you will still be able to re-establish your call and chat history. All data is still saved in the Skype_old folder.

Okay!
I'm newbie here, but it doesn't matter. I dont want to do here anything else, just write off my opinion about the Microsoft's "new" Skype, and I hope they will read...
This is a cropped image - of course hungarian, because I'm hungarian, but I think many of us could see this as well. How this is possible? "The Skype can not start because the system is not available" *** What kind of system? The Skype was on a P2P system, where is impossible that the system is not available! This is why the skype was much better than the Microsoft's messenger. Then they bought it, and make it wrong...
I found a solution for this problem, this can happen if my client is not updated. But IT IS!
How does it works? Can we use the **bleep** Skype how we would like to use? Or this time we need to find an other application (like Viber), and using that while they not buying that as well, just because that is better?

How do I fix Camera Raw in CS6? I get "Could not complete request because the file was not found"

How do I fix my Camera Raw in Photoshop CS6? I tried to view an NEF file in CS6, but it said I had to update my Camera Raw to 7.3 (I had 7.0). I went online and the only thing I could find was to download 8.6 so I started with that, and installed something and it didn't work, and then it told me I couldn't download 8.6 because my OS X is not 10.7 ( I have 10.6.8). Now when I go back into photoshop it gives me this error "Could not complete request because the file was not found" and I cant open any jpegs in photoshop. I have tried shutting down my computer, deleting caches, and uninstalling photoshop and reinstalling it. Still no luck. Any idea how I can fix this?

Follow these instructions to manually update your ACR plug-in to ACR 8.3, which was the last version compatible with your OS:

Could not initialize Photoshop because the disk is not available

I get this message when I try to startup Photoshop:
"Could not initialize Photoshop because the disk is not available."
I found a fix in Tech Notes about selecting the scratch disk and choosing ignore permissions, but I don't even remember what the scratch disk was, so I don't really know how to select ignore permissions on it.
Does anyone know another way to fix this. It seems like this must be some "login-local" preference (meaning that there must be something in the user's local preferences for setting this scratch disk parameter (the only reason I'm thinking this is that if I create another user and run Photoshop, I get no error.)
I looked through ~/Library/Application Support/Adobe for any kind of Photoshop Preference, but I couldn't find a specific preference that stood out. Anyone have an idea?

I just got the same message, "Could not initialize Photoshop because the disk is not available". I had just assigned my primary scratch disk to an internal drive that was empty and had lots of free space. When I restarted my machine, the error message appeared when I tried to open Photoshop.
Not sure why this error occurred, but deleting the preferences did fix that problem... unfortunately, doing that will reset all your prefs = pallets, brushes, actions. I suspect you could just delete the "Adobe Photoshop CS2 Prefs.psp" file and leave the others intact to avoid that.
I would still like to know why changing the scratch disk gives us this problem? I mean, isn't that the whole point of having another internal drive?

How do I get into my cs6 now.
Problem since that extenede for the cloud has been coming up and I have just always quit and never subscribed now today the trial is over and i Have never used the trial and can not get back into cs6 for my work. No support from adobe until monday
any suggestions
Dick

Do you have a perpetual license (not a cloud subscription)?
If so, then you will have received a serial number.
You need to follow the prompts to the point where you enter your serial number and enter it. That should activate the software.
You'll need also to make sure you've updated it to the latest release. The specific number of that will depend on what kind of system you have.

You may have to arrange to take the product into an authorized

if they can apply the correct firmware update, to help resolve the
issue of upgrade; or if they have a way to put it as it was prior to
the attempted upgrade to a later iOS.

Are you able to email from Mail with those two accounts? If so:
1 - go to iPhoto's Accounts preference pane and delete both accounts. Now add them back and try again.
2 - a better solution IMO is to set Mail as the email client for iPhoto is iPhoto's General preference pane. This gives you better access to your contacts, a sent copy of all emails and, if you want a layout similar to iPhoto's, photo layouts located in Mail's stationary.
