Windows 10 as a Hyper-V Virtual Machine

Rather than install directly to hardware I installed the Windows 10 Preview as a virtual machine on a Windows Server 2012 R2 Hyper-V host.
I'm running 2048 MB RAM, dynamic Mem turned on. Only one processor.
So, I'm looking for others who have similarly done so. Did you/do you like it? Are you running into any issues?
For me, I've encountered the following issues:
Enhanced Session Mode: Didn't work. I hit the CTRL-ALT-DEL icon and it went to black screen. Hyper-V Manager showed it at 0% CPU. Turned off Enhanced Session mode and closed RDP window, then I was able to sign on.
A couple of hangs. Had to restart the vm serveral times. My Server crashed. I had to hold the power button down. Came back up OK, no problems since, and I've done multiple restarts on the Win 10 VM.
I cannot get the sound card to work. I get an error that "an error was detected". That's all.
Anyways, post 'em as you get them!

Hi Dave,
I did 2 separate installation of
Windows 10 Technical Preview outlines here. Both are Gen 2 VMs on Hyper-V 2012 R2. Installation went without a hitch. Joining the domain was uneventful (2012 R2 domain and forest level).
I have not had any crashes or blue screens.
CTRL-ALT-DEL is available in Basic session. It's grayed out in Enhanced session. This has been the case with other VMs on Hyper-V 2012 R2.

Windows 8 Hyper-V - Virtual Machine Management Service failed to start the virtual machine

I have Hyper-v running on Dell Precision T3600 with Windows 8 OS. I am trying to start a VM (called Windows8VM) to install Windows 8 in the hyper-v virtual machine, but I keep getting the following message:
"Windows8VM" failed to start.
Failed to start the virtual machine "Windows8VM" because one of the Hyper-V components is not running.
"Windows8VM" failed to start. (Virtual machine ID D670D3BB-9AE2-0453D-9191-EA6EFC242A9C)
The Virtual Machine Management Services failed to start the virtual machine "Windows8VM" because one of the Hyper-V components is not running.
I have turned the hyper-v feature on in the "Turn Windows feature on or off. The BIOS has virtualization enable. Help!!! driving me nuts for a week now.
Nick :(

Okay, I turned off hyper-v, went to bios and enabled Intel TXT(LT-SX) Configuration. Made sure that both Virtualization and VT for Direct I/0 are on. Next, I turned on Hyper-V and I create a brand new Virtual Machine call Windows8 and had
the DVD point to Windows8 ISO file on hard drive. When I clicked on start, it stayed in the Starting status mode for about 5 minutes. Then of course it failed. I looked at the Hyper-V-VMMS log and here is what it output:

Windows 10 Technical Preview - There is NO "Hyper-v Virtual Machine Management" service???

hi all,
There's no such Windows Topic as "WTP Virtualization", so I post this thread here, a somewhat "VIRTULIZATION" related.
I installed WTP (not server) x64 enterprise 9879, and added "Hyper-v Management" feature (management only, without Hyper-v core) in Control Panel. Then I found that there was no "Hyper-v
Virtual Machine Management" in Services panel, and there was no such file "c:\windows\system32\vmms.exe". Therefore I cannot connect to Windows Server 2012 R2 Hyper-v through WTP Hyper-v Manager.
I confirm the reason is what I state above. Firewall rules are properly configured on both Hyper-v server and WTP. I also used hvxxxx.wsf to configre anondcom to be "allow". When
I connect WS 2012 R2 through WTP, Hyper-v manager on WTP says "Please confirm VMMS server is running".
Is it a bug, or lack of implementation, or restriction of preview edition?
Any suggestion is appreciated! Thanks!

Create Hyper-V Virtual Machines with Windows PowerShell searching on hostname

Dear,
I’m a starter with PowerShell scripting an I’m looking for a script to create Hyper-V Virtual Machines with Windows PowerShell. The idea behind the script is that when I run the script its first searching for the hostname. I’m migrating 24 locations and each
location have a different hostname like xxx-SRV001. The script needs to use the first 3 signs from the hostname in this case “xxx” and create 2 VM's with below info:
Virtual Machine 1 2048MB
Virtual Machine 2 4096MB
Location D:\VM\
I can create VM's with Powershell into Hyper-V so only a script to first searching for the first 3 characters of the hostname is enough.
Example:
It's the intention that when the script runs it's looking for the hostname. As example we have hostname 000-SRV001
If the script see the first 3 characters of the hostname, in this case 000 he need to create 2 VMs with name xxx-SRV002 and xxx-SRV004
I think it must be something with
$hostname = "Get-WmiObject -computername $Machine Win32_Computersystem"
But then when i'm asking for $hostname he must give me back the hostname and if the hostname is 1 of the 24 locations then he need to create 2 vm's in Hyper-V with above info.
Can you help me or do you have a script for this?

Juste use :
$vram = 1GB*$vRam
You not need the "
Do you have any error with the creation of the VM?

Error Creating VM on 2011 iMac - The Hyper-V Virtual Machine Management service encountered an unexpected error: The remote procedure call failed. (0x800706BE).

I am running Hyper-V in Windows 8.1 on a late 2011 27 inch iMac. Whenever I try to create a virtual machine I get the error below and Windows warns that it will restart in 1 minute. I tried a clean install of Windows, but my PC still crashes ever
time I try to create a VM. I was able to successfully use Hyper-V in prior versions of Windows on this same PC. Any clue as to what is going on? A driver? Windows 8.1? Mac Hardware related?
I see the following two entries in event viewer but have no other clue as to what is happening:

Hi CharlesPool,
I am assuming that the win8.1 is in-place updated from win8 .
Maybe you need to check the state of hypervisorlaunchtype .
If it is off , please run command " bcdedit /set hypervisorlaunchtype auto "

Hyper-V Virtual machine disappeared

Hello,
I am running Windows Server 2008 R2 SP1. I have the Hyper-V role installed with to virtual machines. I rebooted yesterday after windows updates loaded and now one of my virtual machine have disappeared. I have run through hours of technet
forums trying to find the answer and have come up empty.
I checked ProgramData\Microsoft\Windows|Hyper-V\Virtual Machines and the symbolic link is gone. I tried to recreat it using the mklink command, but every time I recreate the symbolic link to the .xml it comes back as a link to a file folder.
I checked the acl on the virtual machine .xml on my D: drive and the GUID SID is missing. I also tried to add it back via the iacls command but it doesn't seem to exist.
After all that, I decided to recreate the entire virtual machine, but now I can't create virtual machines. I get teh following error:
"Failed to create external configuration store at 'folder path': A required privilege is not held by the client. (Virtual machine ID 0x80070522)"
After that error I opend azman.msc and verified that the initalstore.xml has the administrators group in it.
I do not know what else I can do from here. Any help would be appreciated.

Hi Jumar2,
This will help others who are fighting with similar issues.
Thanks for your sharing .

Hyper V Virtual Machine Creation

While we try creating a new virtual machine for our windows phone application, we are facing the following error.
-Failed to add device 'Virtual Hard disk
-Hyper V virtual machine management service account does not have permission to open attachment.
ERROR: General access denied error(0x80070005)

Unblock whatever it is that you downloaded.
Check that your antivirus software is set with the proper exclusions.
I don't recall anyone reporting this error before - as the installer for the phone emulator generally takes care of the machine creation and permissions.
I can only guess that you are attempting to duplicate the phone emulator VM. If so, use Export and Import.

Hyper-V virtual machines disappearing

Running W10 Enterprise TP with no security software, nothing fancy.
Twice now my Virtual Machine running locally in Hyper-V Manger have disappeared after a reboot. They are still running in the background by their VHDs being in use, but I can't see them to do anything.
Last time this happened, I had to remove Hyper-V, reboot, re-add Hyper-V, and the VM appeared. However, there was something wrong with the VM so I deleted it and started over.
Any ideas?
My idea of a party is a virtualization server and a room of TechNet DVDs

@ThrashZone, Thank you but this is an issue that occurs after it has already been up and running.

Hyper V virtual machine randomly loses network connectivity

I have an extremely odd issue happening on one of my Hyper-V virtual machines. For no apparent reason and completely sporadically my virtual machine will lose all network connectivity. It is a linux Vyatta firewall image. Digging through
the logs shows nothing at all when the machine actually goes offline, but when the machine starts back up I just get a Warning stating the network driver on my virtual machine loaded but has a different version from the server. Server Version 3.2 Client
version 0.2
I've ran the integrated services setup disk and nothing has fixed this. When the VM loses connectivity it is for no apparent reason, sometimes at 1am sometimes at noon, just happens. The only solution is to reboot the VM to bring it back online.
Has anyone else seen this or know of a fix for it? Its starting to slowly drive me insane!
Hyper V Server - Windows Server 2008 R2 - Hyper V Manager Version 6.1.7601.17514
VM - Linux Vyatta Core 6.3

I tried downloading new integrated services disk setup for linux, but Vyatta wouldn't work with it so I was kind of stuck there. And not sure where you are talking about changing NIC to legacy at. I did disable some TCP chimpney settings as
per an article I found, but not sure if it will fix it or not. Sometimes the machine will stay on for a month before losing network connection and sometimes it comes in spurts and happens like 3-4 times over a couple days. Its really odd

Modify the headless options of the BIOS on a Hyper-V Virtual Machine

Hi everyone,
I am attempting to do something which is (surprisingly) complex using a Hyper-V virtual machine. Using VMware Workstation I have been able to boot from the network using VMware autodeploy. This loads ESXi 5.5 as the operating system. This
works great, but I would like to try to accomplish he same feat using Hyper-V, and I've succeeded. This creates is a nested ESXi 5.5 host.
The process was long and painful, but I have gotten to the point that I am able to successfully boot a Hyper-V virtual machine off the network (legacy network card as the boot device) then load the OS. The only problem is that in order to get it to
boot I need to hit shift + o during the ESXi boot startup, and enter the following line:
ignoreHeadless=TRUE
The problem is that I can't do this manually every time. To understand how to fix this, I first needed to understand what exactly "ignoreHeadless=TRUE" was doing. My understanding is that this has to do with the display, specifically:
"Some systems which have a video display device can be configured to report themselves as headless via the configuration, usually in the system BIOS."
I believe this is my issue, by default a Windows Hyper-V virtual machine reports itself as headless, therefore you need to ignore this configuration on startup or ESXi thinks there is a display error.
My question is, can I fix this from the virtual machine side? Can I modify the virtual machine so that it does NOT report itself as headless?

Hi,
The Hyper-V is the full virtualization technology, and it must installed on bare-metal computer, personal experience, if you are using the WDS with Hyper-V environment to
deploy the Windows system, the performance will lower than the physical computer and you must choose the corresponding method if you have the different environment.

(Request for:) Best practices for setting up a new Windows Server 2012 r2 Hyper-V Virtualized AD DC

Could you please share your best practices for setting up a new Windows Server 2012 r2 Hyper-V Virtualized AD DC, that will be running on a new WinSrv 2012 r2 host server. (This
will be for a brand new network setup, new forest, domain, etc.)
Specifically, your best practices regarding:
the sizing of non virtual and virtual volumes/partitions/drives,
the use of sysvol, logs, & data volumes/drives on hosts & guests,
RAID levels for the host and the guest(s),
IDE vs SCSI and drivers both non virtual and virtual and the booting there of,
disk caching settings on both host and guests.
Thanks so much for any information you can share.

A bit of non essential additional info:
We are small to midrange school district who, after close to 20 years on Novell networks, have decided to design and create a new Microsoft network and migrate all of our data and services
over to the new infrastructure . We are planning on rolling out 2012 r2 servers with as much Hyper-v virtualization as possible.
During the last few weeks we have been able to find most of the information we need to undergo this project, and most of the information was pretty solid with little ambiguity, except for
information regarding virtualizing the DCs, which as been a bit inconsistent.
Yes, we have read all the documents that most of these posts tend point to, but found some, if not most are still are referring to performing this under Srvr 2008 r2, and haven’t really
seen all that much on Srvr2012 r2.
We have read these and others:
Introduction to Active Directory Domain Services (AD DS) Virtualization (Level 100),
Virtualized Domain Controller Technical Reference (Level 300),
Virtualized Domain Controller Cloning Test Guidance for Application Vendors,
Support for using Hyper-V Replica for virtualized domain controllers.
Again, thanks for any information, best practices, cookie cutter or otherwise that you can share.

Hi
In my prodcution found hyper v virtual machines have no integrated services was installed should we installed on production servers is any impact if we didnt installed them.
if it should installed then what is the best approch to installed.
Thanks

You posted in the Group Policy forum...
That's a good question for the Hyper-V forum:

Hyper-v virtual machine management in status stopping

Hello,
I had a problem with one vm showing status backing up.
I read on TechNet that restarting the hyper-v virtual machine management service would solve the problem.
I have tried to shutdown the service but it now says status stopping...
How long time does it take to shutdown the service? Is there anything I can do to hurry it up?
ps. I have production vm running on the host that I can't take down...
Regards
Roger

Hi Roger,
I also tested in my lab to disable that service forcibly ,then I found that it will leads the VMs to unexpected shutdown .
Based on this ,it seems that restarting the host is necessary .
Best Regards

How to connect USB external Harddisk to Hyper-v virtual machine

Hi,
We are running hyper-v server 2008 R2, we have external USB harddisk connected in hyper-v Manager, we are not able connect this USB to virtual machine.. is this option is available in hyper-v? if no is there any document from microsoft stating the same?
Regards
Asha

Hi,
Unfortunately, USB is not supported on a Hyper-V virtual machine. You can perform the following suggestions:
1. Offline the USB hard disk on the Hyper-V host machine and connect it to the virtual machine as a pass-through disk(if the USB hard disk is support)
For more information, you can refer to:
Configuring Pass-through Disks in Hyper-V
http://blogs.technet.com/b/askcore/archive/2008/10/24/configuring-pass-through-disks-in-hyper-v.aspx
2. You can also use some USB over Ethernet application.
Best Regards,
