Can we Hyper-V Server 2012 R2 hypervisor on dedicated servers?

Hello, guys!
We have our infra on rented dedicated servers at Canadian services provider.
We used to rent and pay their MS licenses (Win2008R2 Ent) on these servers.
Now we want to use Hyper-V Server 2012 R2 hypervisor on our dedicated servers, because of the smaller footprint, less attck surface, less updates needed to install and no cost.
We installed 5 hosts with Hyper-V Server 2012 R2 hypervisor and now we want to move the rest to it. But their engineer states that "
Unfortunately, if you are going to use Microsoft Server on those servers, I'll have to add the licence as we have an SPLA agreement with Microsoft.
Can you please help to clarify if we're allowed to use this hypervisor or not?
Thank you

Advice on setting up a windows server 2012 domain LAB for study within Hyper V server 2012 r2 machine

HI im wanting to setup a study lab containing several windows 2012 r2 servers (mixture of core and full installs) to allow me to study towards my MCSA in server 2012 r2 and then for MCSE.
Physical equpiment,
1 pc   which is has window 8.1 pro installed from this machine. This machine i would like to remote manage and connect through to my Hyper-v server and then into any of the virtual machines. (this machine is more of a gaming pc so not
able to run to many vm's from it)
2 pc bought Just for study 8 core processor 1 tb of hhd space 16 gb of ram.
This machine i would like to setup using hyper-v server 2012 r2, which then i would create a test domain within it also with some clients allowing me to play and undstand the principles im learning.
now im getting conflictiong information regarding the Hyper-v server 2012.
If i set the hyper-v server up as a standalone in a work group. Would i be able to manage ther VM's within the hyperv server from my external windows 8 pro machine using the remote server management tools or would i need to connect that pc
to the domain.
Things I think i can do but not sure.   as im still learning
Could I setup a server 2012 r2 running AD dns and add the hyper-v role then wihtin that create the rest of the domain inside, allowing me from my other phyical machine log on to domain and manage all servers and machines.
Could I set up as i originally suggested, set up hyper-v 2012 server in a workgroup, then create the domain within the hyper-v server but still connect from my external pc to manage the hyper-v and all the internal VM's within the domain.
I could run a Domain controller on a VM from my other windows 8 machine (within hyper-v or wmware), then on the 2nd machine install the hyper-v server connect it to the domain running from the other machine from what i can see, many people say this is the
better option, BEST Practice, but this is only a lab and i dont require resilience. and i would prefer to have my  as a sever manager via the remote tools.
So what i like to know if you can point me in the right direction either by a guide for someone who has setup a similar to me.
or tell which of the above options is possible or not so i dont waste anytime.
Network, i know i can do this virtually but i already have cisco routers and layer 2 swicthes so i may make the network lab via them.
Thanks in advance for any help you can give me

"If i set the hyper-v server up as a standalone in a work group. Would i be able to manage ther VM's within the hyperv server from my external windows 8 pro machine using the remote server management tools or would i need to
connect that pc to the domain."
It makes it easier to set up if everything is in the same domain, but it is quite possible to manage the VMs without being part of the domain. A very useful tool that I use for my lab all the time (my lab is in a lab domain and my laptop is in the
corporate domain with absolutely no trusts between them) is RDCMAN.
http://www.microsoft.com/en-us/download/details.aspx?id=21101 I all my machines, physical and virtual, defined within RDCMAN and can easily connect to any one of them from my laptop. But to understand how to manage everything remotely, I create
one virtual workstation within the domain and load all the management tools on it. I RDP to the management workstation and perform most management functions, but I can get to any machine directly if I need to.
"Could I setup a server 2012 r2 running AD dns and add the hyper-v role then wihtin that create the rest of the domain inside, allowing me from my other phyical machine log on to domain and manage all servers and machines."
Yes, but you could also build the AD as a VM, too.

Why do I need to install RSAT on Windows 8.1 for accessing Hyper-V Server 2012 R2?

Since Windows 8.1 has Hyper-V Platform and Hyper-V Manager built in to it, if I just enable the Hyper-V Manager on my Windows 8.1 client machine I should be able to access the standalone Hyper-V Server 2012 R2 (which I'm planning to install on my 2nd machine)
right?
Then why every article I found on this suggests to install RSAT on my client machine?

Hi Nero,
RSAT is used for these server/client can not enable hyper-v role to manage the corresponding hyper-v server .
Please refer to following supported OS list of
client hyper-v :
Windows 8 Pro 64-bit Edition
Windows 8 Enterprise 64-bit Edition
Windows 8.1 Pro 64-bit Edition
Windows 8.1 Enterprise 64-bit Edition

How to go back to Win 8.1 after installing Hyper-V server 2012 r2

Hi. I installed Hyper-v server 2012 R2 on a Toshiba running windows 8.1 64bit and now I can not go back to windows 8.1. Every time i start the computer it asks for my password and opens system32/cmd.exe and sconfig.cmd consoles

Did the Toshiba come with Windows 8.1 preinstalled? If yes it possibly has the recovery partition in place that you would use for recovery. I'm assuming if it was an accident then you did the in-place upgrade procedure.
Look at your Toshiba documentation for the procedure to restore.
If you want to add Hyper-V to windows 8.1 in the future, you use programs and features. Then turn the feature on.

Hyper-V Server 2012 Migration Questions

Hello All,
This is my first post here, but I have used these forums many times for information. Sorry in advance for the long post.
I have a few questions regarding migration to Hyper-V server 2012 for my production environment. I have done quite a bit of reading, but I have a few direct questions and I would like to get some direct answers.
My current production environment consists of one PowerEdge 2900 with 2 Xeon X5460 Quad Core 3.16GHz CPUs, 24 GB of RAM and a RAID 10 consisting of 8, 500 GB HDDs for a total of 2TB of storage. I am currently running Server 2008 R2 Enterprise w/ GUI as the
Hyper-V host OS. I have 4 virtual machines all also running Server 2008 R2 Enterprise. The 4 virtual machines consist of 1 domain controller, 1 Exchange Server with Exchange 2010 Standard, 1 Server running SharePoint 2010 Enterprise and the remaining server
running IIS with FTP and HTTP.
The network topology is as follows….
Hopefully it is clear from my diagram that the Hyper-V host OS is connected to the same physical network as the domain, but is not a joined to the domain. I set it up this way because I had concerns about connectivity and manageability because the domain
controller is a guest VM. Also, the IIS server is on a completely different physical network independent of the domain.
What I would like to accomplish is the migration of the above environment to Hyper-V Server 2012 as is. I want to keep my existing guest VMs unchanged and running Server 2008 R2 for now as well as keep the existing network topology intact.
I have 3 additional servers in a separate test environment that would be able to serve as temporary storage or whatever is needed for the migration process.
Here are the two main things I would like to accomplish with this migration…
1. Make the transition from Server 2008 R2 to Hyper-V Server 2012 as a host OS.
2. Migrate virtual hard disks from .VHD to the new .VHDX format.
All that being said, I have finally come to my questions regarding this process.
First and foremost, I would obviously need to back up my current setup in case something goes horribly wrong during the migration. My question regarding the initial backup is would it be better to do a bare metal backup of the Hyper-V host or should I do
individual backups (bare-metal?) of the Guest VMs from within their operating systems?
Second, since I plan to use Hyper-V Server 2012, I will have to manage the host OS using the RSAT from a domain joined client running Windows 7 Professional. How much of a pain is it going to be to setup RSAT and manage the non-domain joined host from a
domain joined client? Is there a better way without using SCVMM or using Server 2012 w/ a GUI as the host OS?
Third, are there any concerns I should have, precautions I should take or procedures I need to do before, during or after the migration regarding the existing VMs and the new virtualized hardware environment on the same physical host?
Forth, should I use the trial version of SCVMM 2012 SP1 (or another previous version) to perform the migration? What should I be aware of using SCVMM for the migration and then discontinuing its use after the migration is complete and moving to management
using the RSAT?
Fifth, if I don’t use SCVMM for the migration, what is the best procedure for moving the VMs? Should I just copy the VHDs to a temporary storage location, install Hyper-V server 2012, copy the VHDs back, create new VMs and attach the VHDs or should I use
the export/import process?
Number six, when is the best time to migrate the VHDs to VHDX format and what would be the best method?
And finally, do I need to worry about USN rollback with a single domain controller? From my reading, this seems to be a point of disagreement. Some people say it could happen while others say it won’t. Is there any point during the migration process where
it could occur either during the copying of VHDs or from the switch to VHDX?
Again, sorry for the long post and thanks for staying with me this far. Any information would be much appreciated

1) As Jens said below with Windows Server 2012 you can simple copy the configuration files and VHDs from a 2008 R2 server to a 2012 server and import them - they one caveat to this is that any vlan configuration is lost and you have to simply re-create it.
Optionally you can also export the virtual machines from Windows Server 2008 R2 and then import them on Windows Server 2012.
2) Remote management in a workgroup does have some caveat's associated with it - take a look at
http://blogs.technet.com/b/jhoward/archive/2009/08/07/hvremote-refresh.aspx. Generally I would recommend joining the Hyper-V management operating system to the domain - not just because of these issues but for a number of other features to work properly
(see below)
3) I always recommend validating the hardware and environment after the installation before migrating critical workloads to it - testing networking, backup etc... to make sure they function as expected. Also ensure that you upgrade the integration
components in the VM's after the migration.
4) That is an option - though you might find you like SCVMM
5) Recreating VM's using existing VHD's has some issues for example the BIOS GUID changes, all of the NIC's are re-plug and played etc... When possible copying the configuration or using export is much better.
6) The sooner the better - VHDx has a number of significant advantages, you can do the migration using the Hyper-V manager UI (edit disk) or via powershell with Convert-VHD. Do keep in mind that during the conversation you need 2x the space (for the
original and the new VHDx).
7) In the past you could get into trouble if you for example snapshotted an AD virtual machine and than reverted it - taking one offline and then brining it back online was never a problem. In Windows Server 2012 we addressed this with a feature called
generation ID's.
Domain considerations... A few things to keep in mind regarding the choice to not domain join the Hyper-V server.
- You can't live migrate virtual machines
- You can't utilize Hyper-V over SMB
- Management is more difficult and less secure

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! :-)

Cannot revert to Windows 8 after installing Hyper-V Server 2012 R2

I own a laptop with a pre-installed Windows 8. I've installed Hyper-V Server 2012 R2 on top of it by mistake, and now I would like to get rid of it and revert it back to Windows 8. I've tried doing so by a backup USB, though it doesn't seem to work. Is there
anyway to do this without having to use a disc? I haven't received one when I bought it.
Thanks for any help in advance.

Why Win2k8 R2 VM on Hyper-V Server 2012 behaves erratically?

Hello,
I realized this strange problem with Windows 2008 R2 VMs running on Hyper-V Server 2012. My Hyper-V Server 2012 host has been running mix of VMs just fine. I've a Linux VM running, a couple of Windows 2012 R2 VMs, a Windows 8.
I created three new VMs, gave them decent hardware. 4 GB of RAM each. A fixed VHDX file of 40 GB. I left processor allocation to Hyper-V. Windows 2008 R2 ISO was mounted to all three. Installation started. The VMs were plugged into an external network to
access internet for Windows activation and software updates.
Installation went smooth. I could log on and kick off windows updates installation. it took a reboot but when it came back, strange things started happening.
First, after VM won't respond to CTRL+ALT+DEL command from the VM console; saying 'VM doesn't did not respond to command'. I inserted integration start up disk from Media Menu on VM's console window. It allowed me to log on this time. I continued
to download/install windows updates to update and complete that. All important updates were selected (even in first step above) and none of optional update was selected.
This round of updates download/install updates finished and VM rebooted. Again, when it became available it stopped responding to any of commands sent to VM, Reset, Stop,Shut down, Turn off and won't allow CTRL+ALT+DEL. Strangely this time it didn't
like accepting mounting integration services start up disk. The message displayed; when any of these actions were performed, is "RPC service not available".
What could go wrong with Windows 2008 R2 VM created just now behaving like this?
Did someone experience issues like this with just built Windows 2008 R2 VMs? Please share and advise.
Thanks.
Regards,
Shahzad.

Hi Adam,
Indeed it is odd. The flow has been following, and I doubt any of these steps had caused any issue.
Step 1. VM started, booted from ISO, installed OS, Reboot. (usual)
Step 2. VM became available, password configured, logged on, checked DHCP assigned TCP/IP Settings.
Step 3. WUAPP invoked to download install updates, updates required reboot, VM rebooted.
Step 4. VM became available, won't respond to CTRL+ALT+DEL (In hyper-V VM console DEL is replaced by End).
Step 5. Integration startup disk inserted, waited couple of seconds, VM allowed CTRL+ALT+DEL.
Step 6. WUAPP invoked again to continue download/install of updates, it finished, VM rebooted.
Step 7. VM became available, won't respond to any command sent to VM from console, just complains (RCP Service not available). Won't accept integration startup disk even.
BTW, the ISO used is trial edition of Win2k8 R2; popularly available for download, the
180 days trial edition.
I couldn't get to stage to assign IP to VM, because I wanted to install all important updtes before I do any thing else.
Regards,
Shahzad.

Hyper-V Server 2012, CAU, Unable to drain roles

Hi,
I have a 2 node failover cluster running Hyper-V Server 2012. Draining one of the nodes for CAU fails without any obvious errors logged. All of the VMs live migrate successfully, after three re-tries node drain fails, the node leaves maintenance
mode, and VMs live migrate back to their original locations. I've reviewed all the event logs on each server and I'm stumped.
All of the networks and disks are in an UP status. CSVs are not redirected and they are all owned by the host having difficulty draining roles.
It seems the best thing to do is to run the cluster validation tests, specifically the storage tests. I won't have a maintenance window to bring
everything down for quite a while however and some of the storage tests are known to be disruptive.
Does anyone have a suggestion?
Thank you

Can I install Windows Server 2012 r2 essentials over Windows 7 Pro

I have new hardware that came with windows 7 pre-installed. It meets and exceeds hardware requirements. Can i install Windows Server 2012 R2 Essentials on this machine. What is the procedure? Any help would be grateful.
Thanks
Woodrow

Hi.
I agree with Milos on this; if you want to install Windows Server 2012 Essentials on a machine which suppose to use Windows 7, I would use it solely for test purposes.
Could you tell us what the computer specifications are???
For anything more serious (and I can see that you want to use this machine for accounting software), I would suggest purchasing a server machine.
However, if you really really want this machine to be Windows Server 2012 Essentials, check this article on technet:

Can't find SQL Server 2012 Configuration Manager

In my Win8 I can't find SQL Server Configuration Manager.
I need to connect to an SQL Database using a specific port.
Does anyone know how to do that?
Thanks a lot!!

Hi Lina,
Did you install multiple SQL Server instances on your local server? We can not configure SQL Server 2012 instance under SQL Server 2008 R2 Configuration Manager.
If you had installed SQL Server Configuration Manager with SQL Server 2012, you can try to run "sqlservermanager11.msc". If this is not opening then you might not install SQL Server 2012 Configuration Manager.

Can we use SQL Server 2012 Web Edition as a witness server in mirroring?

Hi All,
Can we use SQL Server 2012 Web Edition as a witness server in mirroring?
Grateful to your time and support. Regards, Shiva

Hi All,
Can we use SQL Server 2012 Web Edition as a witness server in mirroring?
Grateful to your time and support. Regards, Shiva
As Per BOL
We strongly recommend that the witness reside on a separate computer from the partners. Database mirroring partners are supported only by SQL Server 2005 Standard and later versions and by SQL Server 2005 Enterprise Edition and later versions.
Witnesses, in contrast, are also supported by SQL Server 2005 Workgroup and later versions and by SQL Server 2005 Express Edition and later versions. Except during an upgrade from an earlier version of SQL Server, the server instances in a
mirroring session must all be running the same version of SQL Server. For example, a SQL Server 2005 witness is supported when you are upgrading from a SQL Server 2005 mirroring configuration but cannot be added to an existing or new SQL Server 2008 or later
mirroring configuration.
A witness can run on any reliable computer system that supports any of these editions of SQL Server. However, we recommend that every server instance that is used as a witness correspond to the minimum configuration that is required for the SQL Server Standard
version that you are running. For more information about these requirements
