Missing Virutal Machines on hyper v

Hey there
I have 30 Vm's running on a server core 2008 data center host server core. I added this server to the Virtual machine manager 2008 beta. 22 of the VM's showed up and 8 were shown as missing. After this, I couldn't even see the 8 VM's in hyper v manager on another server.
So I decided to remove the host from VMM 2008 beta hoping they would show up in hyper v manager. that did not happen. So now, I have 30 Virtual machines running on the host, and I can only see 22 of them. I can ping the 8 VM's I don't see, so I know they are up and running.
Is there any way to get these VM"s to show up in the hyper v manager console? Any ideas would be greatly appreciated. Thanks.

Hello,
Have you ever tried to restart VMMS service on the Server Core? I saw this problem before and resolved it by just restarting the service. You can do it by running the following commands:
Net stop "Hyper-V Virtual Machine Management"
Net start "Hyper-V Virtual Machine Management"
Or, if possible, try restarting the physical server to see how it goes.
If this cannot help, please open the Event Viewer on the Full installation of Windows Server 2008 machine, right-click the Event Viewer and select Connect to Another Computer… to connect to the Server Core. See if any errors or warnings are logged there.
Best regards,
Chang Yin

Virutal machines on Windows Hyper-V Server 2012 R2

Hi,
How many Virutal Machines ( Guests) can we create on a host with Hyper-V Server 2012 R2 installed on the host .
Hyper-V Server 2012 R2 is free version from Microsoft right ?
Thanks

What I understood from above is ,if we install the hyper-v server 2012 R2 standard version on the host, we can create only 2 windows VM's.
Not quite. There's no such thing as "Hyper-V Server 2012 R2 Standard". You either install Hyper-V Server 2012 R2 which is free and then license the servers you install on it separately, or you install Windows Server 2012 R2 Standard or Datacenter edition
and configure Hyper-V on there.
I believe you CAN buy a licence for just a virtual machine, though it would be a bit pointless when Standard covers you for two virtual machines.
Going the free Hyper-V Server route is useful in particular if you're installing non-MS VM's which don't require MS licensing, or if you're P2Ving some existing physical servers which are already licensed.
Note, if you install a Windows Server 2012 R2 Standard licence to cover two VM's then it may be worth simply installing that rather than the free version unless you really don't want the UI available on the host. A standard licence covers you for 2 servers,
and as long as the host server is doing nothing other than handle Hyper-V the copy of Standard on the host doesn't count towards it. So for instance you could have Server 2012 standard installed on the host, install the Hyper-V role on it and also install
the IIS role on there, at which point you can only have 1 VM running there on that licence, but without IIS or anything else on there you can have 2 VM's. If you need more than 2 VM's (while not needing enough to warrant the cost of Datacenter) then you can
install a second Standard licence which covers you for another two virtual machines.
There's a guide to licensing Hyper-V here
http://download.microsoft.com/download/7%2F7%2F0%2F7707E736-4557-4310-9709-87358F7E6D1A/WindowsServer2012VirtualTech_VLBrief.pdf though as Eric said it's probably worth giving the licensing guys a call rather than putting your trust in unknown non-MS people
on the internet! :-)

How to Install Hyper-V on a Virtual Machine in Hyper-V on windows 2erver 2012 R2 ?

Hi ,
anybody know How to Install Hyper-V on a Virtual Machine in Hyper-V on windows 2erver 2012 R2 ?
I want to create lab but i couldn't I follow this article but the new VM is off
http://blogs.technet.com/b/gbanin/archive/2013/06/26/how-to-install-hyper-v-on-a-virtual-machine-in-hyper-v.aspx
one of hyper-v component is not running
thanks

Previously it has been blocked to install Windows Server in the VM and then add the Hyper-V Role.
However, it has always been possible to install Hyper-V Server inside a VM. (the free Hyper-V Server SKU)
The Hyper-V Server VM is fully manageable, but it cannot start any VMs.

How to Allow microphone and all hardware in Virtual Machine using Hyper-v

I have recently installed Windows 10 preview in Windows 8.1 pro.
How i can allow Microphone and all things in virtual machine from Hyper-v
Thanks
Thank You , Shan Ali Khan

You connect to the VM using the RDP Client - connecting to the IP / name of the VM over the network.
This enabled all device redirection by default.
You can possibly use Enhanced Session Mode as well. That again uses RDP under the hood.

Type 2 Virtual Machine in Hyper-V will not PXE boot with WDS

Hi
Bit of a wierd scenario this but I'm doing a bit of a lab experiment kind of thing. The setup is as follows:
VMWare Workstation 10 with Windows Server 2012 R2 running as a virtual machine. In VMW10 I have a NAT network interface and a Bridging interface set to load with the virtual machine. These seem to work fine (although the NAT doesn't seem to want to connect
to the internet but that's why the bridging one is there in addition).
Server 2012 is configured with the following roles:
ADDS, DHCP, DNS, Hyper-V, Printer, WDS
I have correctly configured WDS to work on the same machine as DHCP and I can get PXE boot working with WDS on a Type1 Virtual Machine in Hyper-V using the Legacy Network adapter. My problem is when I try and PXE boot on a Type2 Virtual Machine (this type
is new in R2 and should eliminate the need for a legacy network adapter) using the same network interface that I used for the Type1 machine, I get an IP address from DHCP but WDS doesn't seem to respond. Instead I get the "PXE-E16: No Offer Received"
message. I have tried just about everything I can think of and spent the whole day trying to figure out why this is the case but came up with nothing. Has anyone else encountered this or can anyone shed any light on the matter?
Many thanks in advance

"VMWare Workstation 10 with Windows Server 2012 R2"and "Server 2012 is configured with the following roles: ADDS, DHCP, DNS, Hyper-V, Printer, WDS"
Hyper-V is not supported to be run as a VM. It is a Type 1 hypervisor, which means it works on the bare metal. You have it running as a VM on a Type-2 hypervisor, so it has no access to the bare metal. Yes, VMware may have made it so some
things work in that environment, but it is not a supported (or tested) environment for Hyper-V.

MTM Is possible make an exploration test with action recording on lab center machine (using hyper-v)?

Hi everybody.
I am getting crazy with Lab center. I cant record an exploration test if i try to make it on Lab center's remote machine.
I have follow msdn help. And if i make it on local machine it works fine.
Test agent is configured correctly like "Interactive process".
On lab center, my Lab status is "Ready".
Connecting with lab center to target machine, Test Agent status is "Online" before run exploration test.
While exploration test is running, Test Agent status is "Running Tests".
But when I make click on "Create Test case" there isn't any information of desktop click events from target machine.
By other hand, when i finish there are attachments file with info from target machine. As you can see on the flowing pick:

Harddisk damage after sleep mode while running 3 virtual machine on Hyper-V

Hi, I have laptop with specification Intel Core i3, 8 Gb ram, 500 Gb 5400 rpm Hdd. I am running 3 virtual machine on that laptop using Hyper-V. Each vm have 1 Gb ram and 1 core processor. I left the laptop for
lunch. After comeback from lunch I see that laptop on sleep mode. I press the power button to turned back on the laptop, after the power is on, the harddisk won't boot and the disk become damage. Is there anyone could explain why that is
happen? Thanks :)

Hi Budi-Kurniawan,
Based on your description, this issue shouldn’t be caused by current configurations on your environment (as
you described: wake up from sleep mode while run 3 virtual machine on Hyper-V). I guess that there are some troubles in this harddisk. As Dave mentioned, please contact with laptop manufacturer and confirm it. I believe we will get a better assistance there.
Best regards,
Justin Gu

No longer able to view virtual machine from Hyper-V Manager

From the Windows 2008 R2 host machine, I can run the Hyper-V Manager and 'connect' to the Virtual Machine. The window pops up with nothing but a gray background (clearly the same gray background of the log in screen), but no 'ctrl-alt-delete' prompt
and no ability to log in. This was previously working fine.
Note that I can still make a Remote Desktop connection to the Virtual Machine and it works fine.
Thanks.

Hi,
I never seen this issue before, base on my experience, it may cause by your AV soft block some critical components of Hyper-V host, please try the following exclude specific
directories or process with your AV soft.
•Default virtual machine configuration directory (C:\ProgramData\Microsoft\Windows\Hyper-V)
•Custom virtual machine configuration directories
•Default virtual hard disk drive directory (C:\Users\Public\Documents\Hyper-V\Virtual Hard Disks)
•Custom virtual hard disk drive directories
•Custom replication data directories, if you are using Hyper-V Replica
•Snapshot directories
•Vmms.exe (Note: This file may have to be configured as a process exclusion within the antivirus software.)
•Vmwp.exe (Note: This file may have to be configured as a process exclusion within the antivirus software.)

IP Virtualization not working in Virtual Machine on Hyper-V

Hello everyone. Have such issue. We are using cisco agent desktop for our users. For working in Terminal server environment it needs dedicated IP for each program session. Currently we'are using hardware server with Windows Server 2008 R2 SP1 with RDS.
We've added IPpool in registry for Virtualisation per program. It works fine. Now i'm trying to create a virtual machine with WS 2012 R2 with the same configuration(Hyper-V 2012 R2). The problem is it doesn't work. When creating new session or launching new
program i get APIPA address or get nothing at all. Will it work or still this functionality doesn't work?

have you setup the IP virtualization GPOs in the new environment?
computer configuration > administrative templates > windows components > remote desktop services > remote desktop session host > application compatibility
I'm not sure what regkeys you have implemented but you may want to see if they still apply to 2012 R2, you might have to remove them

Backing up virtual machines in Hyper-V: theory question

Hello!
This article http://msdn.microsoft.com/en-us/library/dd405549%28v=vs.85%29.aspx says:
"Hyper-V uses the Volume Shadow Copy Service (VSS) to backup and restore virtual machines (VMs).
If the backup (volume snapshot) integration services are installed in the guest operating system, a VSS requester is installed that will allow VSS writers in the guest operating system to participate in the backup of the VM. "
Backing Up the Virtual Machines
Hyper-V uses one of two mechanisms to back up each VM. The default backup mechanism is called the "Saved State" method, where the VM is put into a saved state during the processing of the PrepareForSnapshot event,snapshots
are taken of the appropriate volumes, and the VM is returned to the previous state during the processing of the PostSnapshot event."
The other backup mechanism is called the "Child VM Snapshot" method, which uses VSS inside the child VM to participate in the backup....
Backup (volume snapshot) Integration Service is installed and running in the child VM.
The child VM must be in the running state."
Putting it all together: the backup integration services are installed in the guest operating systems by default (at least in Win2008-2012R2), but "The default backup mechanism is called the "Saved State" method,...",
wich does NOT use child vm snapshot creation. It means that checking the "Backup (volume checkpoint)" checkbox changes nothing (at least with running VMs) because the default method is "Saved state":
Q1: if the default method is "Saved state" and my VMs are running what should I do to take a backup by using
"Child VM Snapshot" method?
Q2: is there any difference between a backup created by method 1 and method 2?
Thank you in advance,
Michael

Hi,
The two backup mechanisms used in the different backup scenario:
Short to say is:
Perform a backup from the server running Hyper-V
(host).
Perform a backup from
within the guest operating system of a virtual machine.
The detail explain is:
There are two basic methods you can use to perform a backup. You can:
Perform a backup from the server running Hyper-V. We recommend that you use this method to perform a full server backup because it captures more data than the other method. If the backup application is compatible with Hyper-V and the Hyper-V
VSS writer, you can perform a full server backup that helps protect all of the data required to fully restore the server, except the virtual networks. The data included in such a backup includes the configuration of virtual machines, snapshots associated with
the virtual machines, and virtual hard disks used by the virtual machines. As a result, using this method can make it easier to recover the server if you need to, because you do not have to recreate virtual machines or reinstall Hyper-V. However, virtual networks
are not included in a full server backup. You will need to reconfigure the virtual networking by recreating the virtual networks and then reattaching the virtual network adapters in each virtual machine to the appropriate virtual network. As part of your backup
planning, make sure you document the configuration and all relevant settings of your virtual network if you want to be able to recreate it.
• Perform a backup from within the guest operating system of a virtual machine.
Use this method when you need to back up data from storage that is not supported by the Hyper-V VSS writer. When you use this method, you run a backup application from the guest operating system of the virtual machine. If you need to use this
method, you should use it in addition to a full server backup and not as an alternative to a full server backup. Perform a backup from within the guest operating system before you perform a full backup of the server running Hyper-V. For more information about
storage considerations, see the following section.

Vhd has the sama function as virtual machine or hyper-v in windows 8

hi,
is VHD has the same function as hyper-v or virtual machine. if yes then I can make virtual machine from windows 7 home premium if the hardware support it.
thanks
johan
h.david

All VHDs are Virtual Machines and have the same function since they emulate a hardware environment, but they are not compatible between the different VM software. They each have their own structure and are not directly compatible. There are utilities
that can be found on the internet that claim to export or import VMs from varies different VM software.
Windows 7 XP Mode and Virtual PC use the same structure, but Hyper-V is a different structure.

Hi,
I got this error on one of the VM (web server) backed up usng HYPER-V 2008 R2 and when I looked up, there is an microsoft hotfix for the same issue.
Microsoft KB Hotfix:
A backup of virtual machines fails when you use the Hyper-V VSS writer to back up virtual machines concurrently on a computer that is running Windows Server 2008
http://support.microsoft.com/kb/971394
But, the VM (web server) is running Windows 2008 R2 - SP1.
Hotfix says - To apply this hotfix, your computer must be running one of the following operating systems:
Windows Server 2008
Windows Server 2008 Service Pack 2 (SP2)
Does it mean it does not apply to Windows 2008 R2 | SP1 ?
When I checked the :
Swprv.dll version, it was higher than the one mentioned in the hotfix.
Thanks for any help.

Hi Ashwin,
I am assuming that the VM(web server) is using SQL .
Please try to disable SQL Server VSS Writer in services.msc , then retry WSB again .
Hope this helps

Cannot connect to virtual machine in hyper-v

One of our servers got corrupted and I managed to salvage the VHDs of the two VMs we were running on it. The server was Win Serv 2003 and was running virtual server.
Now I'm trying to import the VHDs into Hyper-V on a newer 2008-R2 server and while the VM seemed to import just fine I cannot connect to it. Each time I try it gives me this error:
"Cannot connect to the virtual machine. Try to connect again. If the problem persists, contact your system administrator."
I think the issue could be that the VM was apart of a domain and now I'm trying to connect with a server that is on a different domain and has a different DNS.
Is there anyway I can save this VM and not have to start from scratch?

Hi,
Is Windows Server 2003 is a DC? Is there a backup DC for Windows server 2003 if it is a DC?
If you logon with domain account, you cannot connect to the origin domain if you don't have DC or you haven't restored DC. To fix this issue, you can restore Windows 7 to the point when windows 7 doesn't domain if you have such a restore point.
Also, if you have DC and still connect to the virtual machine, i recommend you to log on the Windows 7 client with local adminstrator , disjoin from origin domain, then re-join the domain. At last, it will work well.
