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.

I am setting up windows server 2016 for the first time and wanted to know if I wanted to setup additional server AD, hyper-v, other servers to add to a domain etc, would I need to have a separate server for each (physical) or create them as I've seen in videos after installing the initial windows server 2016?

This is for a home production environment?

Dears,

I have 2 Physical Servers.
1 is having my VMs (5) and the other one is having REplica's of those VMs using Veeam.

The replicas are getting big (coz I increased the VMs sizes of their HDDs. and I am running out of space In the Replica Folder (D:\) of the second Physical server.
My question is the following
Can I delete those replicas and re-create them on my NAS ? (I have a QNAP that has enough space). or the replicas can only be on the Fixed disk of the Server (second Server that has Hyper-v Installed ?
Is it "dangerous" to delete the replicas ? How do I delete them ? just delete ?

Thanks for pointing me to the right direction

Is there any best practice in how to upgrade a Hyper-V 2008R2 Cluster to 2016, without destroying the cluster?
We have active VM's on both nodes.

Can a Windows Server 2012 Hyper-V VM be exported and then imported on another Windows 2012 Hyper-V host machine?  Or can the VHD be used on a new VM on a different host machine?

I have Hyper-V set up on a Windows 2008R2 and I created a VM with Windows 2008R2 and given it 4vCPU's and 24GB RAM. What size do I best give the Pagefile on my VM?
I read multiple things about this like 24GB+256MB.
BUT, why would I give it that many virtual memory (pagefile) as it already has 24GB of RAM?

I have a newly built windows 2012 R2 server with all updates installed that has been configured as a clustered Hyper-V server.  Everything is installed and passed validation.  When I go to create a new vm, I supply all the required information, name, memory, disk size, network, where to store the vhd and where to pull the OS from.  It builds the vm and leaves it in the off state.  When I start it, it starts to load the OS, I get the progress bar with files loading, then I get the error:

EXITING:  unable to find root\cimv2 service -2147217402

I've read through multiple threads and cannot pin down a fix to this error.  I find lots of threads relating to XP, Win7, nothing relating to W2k12 or this specific error.   Anyone know what the number refers to?   I checked the event logs and nothing there.     Several post seem to relate this to WMI.  I checked the repository and it states that it is fine.     I've been on this for several days and have gotten no where.

Trying to run mutiple versions of MS Access Run Time on Windows 2016 Server with mutiple CPUs & plenty of ram AT THE SAME TIME

To create a large number of reports at the same time. Kind of A Simple Parallel Solution.

But EACH added Access.exe DECREASES performance (opposite of intended need) so i am thinking i should put each MS Access Run Time into its OWN VM window or even better containerize or dockerize each MS Access exe... but i do not see anybody else explaining or doing the docker/containerize method by step by step example.

Anybody have experience doing this... ?

1 - Maybe assigning specific individual threads to each MS.exe and only that MS.exe ? Has anybody done this idea that way ?

2 - The Virtual Machine way is a bit of overkill and a big setup and cost but now with Microsoft going containers with Win 10 and Windows Server 2016... Containers (docker etc) may be the way to go cost and effort wise.


Thoughts ?

On a single open license of Server 2016 Standard, with a single processor, does the licensing give me the permission to install the FULL Hyper-V host (with the GUI) plus the ability to install 2 VM's on top of that host?
Thank you

Hyper-V installed on Windows 2012 r2. HP 360 G9 64 GB, 2 TB raid 10 disks. I have installed 2 vms; 1 Domain controller with SQL standard 2016 and 1 Remote desktop server +gateway. For both servers 1 cpu was added. I want to add more vcpus or more cores to them. Is this possible without getting errors, or problems with blue screens?

How much do i need?

My ONE physical machine has 6 test VM, each requiring the same amount of resources

 1. How many virtual processors should I setup on the attached screen for each VM ?
 2. Can VMs dynamically use more processors if the attached is set to a default of "1" ?
 3. Anything else I should know about "virtual processors" setup ?

Hi all... I've been having issues with my RDC connection to one of our servers.  It is a Hyper-V hosted server that RDC was working fine on for months.  It recently stopped allowing connections to it and I've had no success with any of the many suggestions I've come across on other blogs.


From a command prompt on the server that I can't RDC TO it appears to be running just fine
C:\Windows\system32>netstat -a

  TCP    0.0.0.0:3389           CRS-DC-1501:0          LISTENING

Open in new window


On another PC that I'm using to connect to the server I'm getting an error
C:\>telnet 192.168.2.252 3389
Connecting To 192.168.2.252...Could not open connection to the host, on port 3389: Connect failed

Open in new window


Pings to the server are successful.  What I am missing?

Thanks,
Greg

Please refer to the screen shot attached.
There are two disk icons in blue color (G: and F: drive), which I circled. What special are they? Why are they in blue color?

I just turned on Hyper-V on a Windows 10 Pro system.
Then I turned on VirtualXPVHD.
All seemed to go well.
But now if I get the mouse cursor into the Virtual Machine Connection, the cursor is stuck there.
[move the cursor into the window and then right click to show the cursor there...]
Right-ALT + Left Arrow fixed it once ONLY.
CTRL + Right-ALT does nothing.
I have found that CTRL+ALT+DEL that opens things like Task Manager will do the trick and all one has to do is Cancel.
BUT...
The cursor won't get out of the XP desktop in order to click on File, Action,etc. or the control icons Shutdoen, Save, etc. nor the upper right controls for full screen, minimize, etc. AND if the resolution is too high, one can't get to the scroll bars to scroll down to see the task bar.
XP Mode under Win7 worked a lot better than this it seems.....

We have a Windows Server 2012R2 that is used as a Hyper-V host for two VMs. It has been working perfectly until recently. We changed the Admin login password out of necessity. Since then, when we reboot the server, the drives that are encrypted with Bitlocker require me to enter the authentication key (password) to unlock the drives. To do this, I go into the "File Explorer" and double click on the encrypted drive. It then brings up the "password" box. It is the same password as the admin login so I don't understand why it would require additional authentication.
Is there somewhere else I need to enter our new password?
Thanks so much for your assistance.

I have been running my Hyper-V Host server on a trial version of server software  and now  has expired .
I have a software with a valid license .
Do I need to back up the VM's Wipe out the server and reinstall Server 2012 ? or is there some way to simply use the new license ?

Hi,

I had a test virtual machine that seemed to have died when the physical host restarted.  When I look at it in Hyper V it says the following:

Cannot connect to virtual machine configuration storage.

I have the xml files and the VHD but I'm just not sure on how to bring them both together again.

Cheers

Hello, I want to upgrade a Hyper-V VM server 2012 Standard to Server 2012 R2 Standard because of version requirements for an application I need to run.
When going through the DISM process I get these results shown in the attachment.  I have licensing for 2012 R2 not for Data Center.  Any Ideas on how to resolve this?

Thank you 1212Pro

I have a program for virtual reality that usually uses a desktop with i7 32 gb and 1080 graphic card.


I want to try to run it on a server with two 1080 graphic card, and has enough memory or and CPU's.

the question what is the best way to test it? VMware ? Hyper V? what kind of configuration ?

Got 3 Hyper-V VM's on a 2008r2 server and I want to move them to a 2012r2 server.  I'm seeing lots of conflicting information on how to do this or if it can be done at all.

I don't have the hardware to setup a 2012 host so I'm hoping I can do it right from 08r2 to 12r2

Thanks!

I wish to configure a vSwitch in Hyper-V.

I have a 6-port trunk (3 from one physical switch and 3 from another). I thought i would only have to click create vSwitch and then select the NIC's which are configured as trunks on the physical switches, however i can only select one NIC per vSwitch.

I have read up and a couple of guides suggest that this can be achieved using powershell only.

If someone could educate me with this that would be amazing. Maybe i am missing something critical here.

Hi, trying to find easiest and most trouble free solution to migrate 2x Exchange 2010 from separate organisations into single 2016 DAG.
Current config is as follows: 2 separate forests/domains (domain1.local and domain2.local) with 2 Way AD Trust enabled connected via fast leased line. Each domain has Exchange2010 server (no exchange federation or anything).
Plan is to create 2016DAG on Hyper-V cluster in Domain1.local and migrate everything from Exchange1.domain1.local and at later stage migrate Exchange1.domain2.local to same DAG.
Each server has multiple trusted domains etc. Any suggestions appreciated. thanks

I am running VEEAM Backup & Replication 9.5 on a Windows Server 2012 R2. VEEAM is configured to backup VM's from 2 Hyper-V Servers that are running Windows Server Data Center 2012 R2. While all VM's backup successfully 'on occasion', often, I get the following error:

Failed to create snapshot (Microsoft Software Shadow Copy provider 1.0) (mode: Veeam application-aware processing) Details: Writer 'Microsoft Hyper-V VSS Writer' is failed at 'VSS_WS_FAILED_AT_PREPARE_SNAPSHOT'
[/b]

I go to the VM Server identified, run the command "vssadmin list writers", and see that a number of VSS entries says 'timed out. I stop/start the Volume Shadow Copy service then restart the server. The backup jog then completes successfully. This issue will occur again after the 2nd or 3rd successful backup and again, I have to restart the server to get successful backups.

Obviously I cannot continue restarting these affected servers (all of which has databases including Exchange Server 2013). Is there anything that would likely cause the VSS services to periodically time out and fail a backup? Thanks

Hi, I have being playing with Windows Server 2008 R2 several years. With Mysql server, Files share and a SmarterMail app.
I have use it in a local lan but with access from internet (both RDP and Mysql Server)

I am now trying to virtualize it. I have use disk2vhd to "backup" my 2008R2 installation.

I have save both RAID 1 disks (just in case). I have use another hard disk to make these tests.

I have install in the new hard disk Windows Server 2012 R2 Standar with GUI.
I have add Hyper-V role and I have create a new VM with the VHDX that I created .
I can open and start my VM, but I have NO idea how to configure all of stuff in HyperV to get my Mysql Server working again.
I have power off the host's firewall to do the test, but not luck.

I have in my new host (WS2012R2) the same IP that I had in my WS2008R2 server.

I have create only a external virtual switch.

But I can't connect to mysql from local lan (also I can't from internet).

Please, how could I do this simple configuration?

My main objetive is virtualize my old server to make easy the upgrade of hardware of my server, or the server itself. After, I could also configure a new VM with Windows Server 2012 R2  and begin to install slowly all things (mysql, smartermail,...) and check them before "shutting down" the old WS2008R2 VM.

Could anybody help me. Probable it will be very easy, as  I have only one host, and one guest.

Regards,
