Hi, 

I am bulding a Highly available cluster from two Hyper-V 2012R2 core nodes and need to clear some things.

I would like to know, how to solve AD, when I need the domain controller Highly available.

I thought I would have one domain running on a separate server (third server, not a node of a cluster), just for the cluster and Hyper-V services and a second one, running the whole Company domain.

Can this be solved another way? E.g. installing full WS2012R2 as nodes and using them as domain controllers? I would like to avoid having another server running. 

Thank you.

We have our first Hyper-V Server 2012 R2 server setup. This is not standard Server 2012. It's Hyper-V Server 2012 R2 so there's no UI to speak of. This is our first attempt to connect a Hyper-V server to our LAN.

We need to keep this server on a Workgroup and not make it a Domain member as it will be used as a demo server for clients. We need to be able to access a share on a domain, however. We have NOT been able to do this. Here's the scenario: ISO shares are on the CorpDom domain on \\ServerDC1\ISO-Shares. We can "see" the ServerDC1\ISO-Shares shared folder but we get denied access to it.

We need to be able to access this for different clients so it's important we understand how we need to connect this Hyper-V server to anyone's domain network and access a shared folder.

To sum it up: Hyper-V1 on Workgroup needs to be able to access a shared folder on server \\ServerDC1 in the CorpDom (or any other) domain.

Can someone shed some light on this? we want to get our first Hyper-V server setup and running a VM or two :-)

Hi

We are running Server 2012 (not R2) Hyper-V environment and have a question about testing Replication.

I have a problem where I have a very large snapshot on our SQL Server.  I made a thread about it (which was answered) here, but on going to delete the snapshot realised that there was no delete option.  Upon further investigation I noticed that the snapshot was the "initial replication snapshot" from when I set up Hyper-V replica back in January 2014.

I have concocted a plan to merge this snapshot with the original VHD (for the OS) and simply create new VHDs for the database and logs files and copy the files across to them.

Before I do this I want to test Replica has been working OK (Replication appears normal in Hyper-V Manager) by doing a test failover and checking that I can access the databases OK.

Is there any reason that the replica server may have been affected by the initial replica snapshot not being deleted and can anyone think of any reason why I should not do a test failover in such circumstances?

Many thanks

When enabling replication on several VM's, I receive Hyper-V failed to enable replication for virtual machine "virtualmachinename": Incorrect funciton. (0x8007001). However this error doesn't happen to all VM's and it isn't related to any particular host.

I've traced this down to a VSS error, however when running ">vssadmin list providers", I receive the following indicating there are no errors:

Has anyone run into this before?

-Jeremy Houp

hi friends

i have encountered an strange problem.

in my servers with windows server 2008 R2 full installation (not server core) & also win 2012 R2 full installation, when in my virtual machines (VM OS = win 2008 R2) , in disk management snap-in i convert basic to dynamic, system normally boots after restarts & no problem occurs.

but i have another server on which i have installed "windows hyper-v server 2012 R2" which is core edition. on it i also have virtual machines. in these VMs when i convert their disk from basic to dynamic, then after restart system remains in the black screen & never boots.

any help please

thanks in advanced

We are building out a new 2012 R2 Hyper-V cluster. The old environment is a mix of Cluster Shared Volume drives and LUNs presented just for the a VM itself.

I had planned on presenting everything in the old environment to the new environment and then just using the cluster migration wizard to move VM's over a few at a time.

I ran into a problem when I connected my first host to our SAN today.  It is in a group that has over 70 LUN's presented to it.  Once I connect to the target the host just cripples.  I am not having Memory or CPU issues but Disk IO issues.  I noticed that the host now sees all 70 plus LUNs and has tried to bring those disk online as well.

I don't want them online right now.  I just need the quorum drive and a few of the newly created LUN's online to finish creating our Cluster so we can start migrations.

Why is the Host trying to bring these drives online?  As soon as I click on Devices in the iSCSI initiator the program locks up and doesn't respond. 

Is there a way to setup the target but force the OS not to bring any of those disk online?  I removed the favorite target, and there are no items listed in the Volume List under Volumes and Devices.  However if you go to Disk Manager it shows all 70 plus disk and most of them now show online except for my newly created LUNs which are not initialized yet.

I know, there are questions why to do so: My answer: I want it that way and I live with the consequences.

So how can I force my Server to show me Hibernate. Even when I shut down the HV Service, I get no Hibernate. Sleep mode would be ok too :D

Many thanks for a usefull answer :)

RE JUST THE configuration files not the virtual disk.

The default location is C:\ProgramData\Microsoft\Windows\Hyper-V.

If they are JUST configuration files then I would not need to bother myself about performance issues. They get loaded, the VM powers up and the disk where the vdhx does all the work?

However I notice that they grow and get very large. Why is this? Does this mean that there is a large amount of disk io to consider?

Would there be a significant advantage in having them on a separate disk?

Having them  on a dedicated ssd disk is obvious going to be better than having it on a SATA 5400 disk. However  I dont care  that the VM would load 2.3 seconds quicker,  I am talking about a real noticeable  difference once the server is up.

Hi,

I'm a bit confused  if it is possible to upgrade Windows Server 2008 Standard SP2 and the Hyper-V Role enabled to Windows Server 2012R2. This page says NO:

http://technet.microsoft.com/en-us/library/dn303416.aspx

But in this topic I read that it should be possible, but only when the Hyper-V Role is enabled.

Hi,

I have Server 2012 R2 VMs on my Hyper-V server. All are running the integration tools (up to date) and the network settings at the VM level (ie protected network, etc) are all the same.

However, some VMs do not report an IP address in the Hyper-V manager and when opening the vm console they display "Connecting to [VM NAME]...". If I try to shutdown (even with the guest services checked in vm settings), I get an error. Heartbeat communication is listed as lost.

I am running Hyper-V on Enterprise Server 2012 R2. I have a number of physical Windows 7 machines on the Network and all can "Map" the Network from their Network and Sharing centre. I have created a Windows 7 Ultimate VM in Hyper-V and as soon as it is started, all the physical Windows 7 machines on the network lose the ability to Map the Network. The Windows 7 VM can't map the network either.

I have found that the only way to restore the functionality(to both physical and virtual Windows 7 machines) is to disable the LLTP Responder in the Windows 7 VM's virtual Network Connection properties.

Has anyone else seen this and if so, is it fixable? Is it likely an incompatibility between the LLTP and the Virtual Swiitch on the server?

Hi All,

I have been trying to enable the Hyper-V role in server 2012R2 standard, but on restarting it fails to install, then recovers back to how it was. I've looked through the logs and found the following.

For a customer we have a MAIN/DR solution based on Hyper-V and Replicas.

Main is equipped with 2 x Windows 2012 in a cluster, DR has one host standalone with Hyper-V.

The whole shebang is managed via SCVMM 2012 and we have replication enabled for around 4 VM's going from MAIN to DR.

Everything is working ok for a while and then all of a sudden we're getting events in our NOC about the fact that the replication has stopped. Upon further investigation we found a couple of events stating:

"Hyper-V failed to open the file 'C:\ClusterStorage\Volume1\VP-SCSQL01\VP-SCSQL01_E.vhdx' for replication in primary server for virtual machine 'VP-SCSQL01': General access denied error (0x80070005). (Virtual Machine ID B7020EE9-A781-4F50-B387-E781FC7F2315)"

When we recreate the replication (so really deleting everything and setting the VM replication up from scratch) it starts and works fine. Resuming replication does not work.

Hi All,

can anyone please confirm if pxe boot works with gen 2 vms in hyperv? I have wds installed in standalone mode. When ever I create new gen 2 vm, it takes ip, downloads some file and it says 

Station IP address is x.x.x.x
Server IP address is x.x.x.x
NBP filename is boot\x64\wdsmgfw.efi

NBP filesize is 1459552 Bytes
Downloading NBP file...
PXE-E18: Server response timeout.
Boot Failed. EFI SCSI Device

Boot Failed. EFI Network.
No Operating System was Loaded. Press a key to retry the boot sequence

I have tried with and without enabling secure boot option. I have wds(standalone mode), MDT and gen 2 vms. Can anyone please guide me how to make gen 2 vms boot over pxe?

Hi I have a 2 node fail-over cluster running 2008 R2 Server core cluster, recently we purchased a SAN switch since we needed to add another node to it. we need to have zero downtime when connecting the new SAN switch. since MPIO is in place we can unplug Fibre channels one by one. i would like to know the status (active path/passive path) of MPIO when i disconnect one FC card. 

Thank you

I am testing the following scenario:

1. WinRM client is running on a Windows Server 2008 with German locale
2. Hyper-V (and WinRM service respectively) is running on Windows Server 2012 R2 with English as default locale and German locale installed in addition
3. Msvm_ComputerSystem instances are enumerated (sample command used: winrm e wmi/root/virtualization/v2/Msvm_ComputerSystem -r:10.10.10.10 -u:administrator -un -encoding:utf-8) 

Observed: the returned result contains values that are with English locale - Msvm_ComputerSystem.Caption is equal to "Virtual Machine" (although I can see that the wsman:Locale element is present in the WSMAN request with its xml:lang property set to "de-DE")

Expected: the returned result should contain values that are with German locale - Msvm_ComputerSystem.Caption should be equal to "Virtueller Computer".

Note1: the behavior is inconsistent - I've been able to get result with either German or English locale values.

Note2: when I am getting a result containing values with English locale, I also see that the WSMAN response has the soap:Envelope element with its xml:lang property set to "de-DE".

Below I am providing the SOAP transactions for the following cases: 1) a WSMAN client sends a request with en-US locale; 2) a WSMAN client sends a request with de-DE locale.

Hello,

This is my home test configuration. I have Windows Server 2012 with two NICs. I do not have domain or DNS servers. My Cisco Router assigns DHCP addresses. On my server, I have Hyper-V enabled and one of the NICs is used for Hyper-V traffic only.

Now I need to add another NIC connected to the same network. One of my VMs (Ubuntu) should use only this NIC to communicate with my network and Internet.

I added another NIC, added new External Network with this new NIC to the Hyper-V Virtual Switch Manager. If I assign this new external NIC to my VM, I can connect to any machine on my network, but I cannot connect to the Internet. I receive "destination host unreachable" error.

If I assign my old NIC to this VM, everything works, but I need to use new NIC with that VM.

Can someone help me with this?

Thank you. Eric.
