Network setup on Hyper-V 2012 R2

Hello!
I have A Windows Server 2012 R2 with Hyper-V role installed. One NICs for all (I know that it is not very good but can't change)
In this setup I also have a 5 guests with Windows 8.1. Each of the guests have the following requirements:
1. Must have access to the Internet
2. Must be accessible via RDP from any place in Internet
3. Have access to file shares of each other
What is the best way to setup virtual network?

Hi Stanislaw,
" 2. Must be accessible via RDP from any place in Internet "
In addition ,If you intend these VMs to access internet via NAT , I mean you just have one public IP for them , after you connect these VMs to the external virtual switch , you just need to enable their 3389 port and forward
these port to public IP's different ports .
Hope it helps

Hyper-V 2012 High Availability using Windows Server 2012 File Server Storage

Hi Guys,
Need your expertise regarding hyper-v high availability. We setup 2 hyper-v 2012 host in our infra for our domain consolidation project. Unfortunately, we don't have hardware storage that is said to be a requirement that we can use to create a failover cluster
for hyper-v host to implement HA. Here's the setup:
Host1
HP Proliant L380 G7
Windows Server 2012 Std
Hyper-V role, Failover Cluster Manager and File and Storage Services installed
Host2
Dell PowerEdge 2950
Windows Server 2012 Std
Hyper-V role, Failover Cluster Manager and File and Storage Services installed
Storage
Dell PowerEdge 6800
Windows Server 2012 Std
File and Storage Services installed
I'm able to configure the new feature about Shared Nothing Live Migration - i'm able to move VM's back and fort between my hosts without storage. But this is planned and proactive approach. My concern is to have my hyper-v host to become highly available in
the event of system failure. If my host1 dies, the VMs should go/move to host2 and vice versa. In setting this up, i believe i need to enable the failover clustering between my hyper-v hosts which i already did but upon validation, it says "No disks
were found on which to perform cluster validation tests." Is it possible to cluster it using just a regular windows file server? I've read about SMB 3.0 and i've configured it as well i'm able to save VMs on my file server, but i don't think that my hyper-v
hosts are already highly available.
Any feedback and suggestions or recommendation is highly appreciated. Thanks in advance!

Your shared storage is a single point of failure with this scenario so I would not consider the whole setup as a production configuration... Also setup is both slow (all I/O is travelling down the wire to storage server, running VMs from DAS is ages faster)
and expensive (third server + extra Windows license). I would think twice about what you do and either deploy a built-in VM replication technologies (Hyper-V Replica) and apps built-in clustering features that does not require shared storage (SQL Server and
Database Mirroring for example, BTW what workload do you run?) or use some third-party software creating fault tolerant shared storage from DAS or investing into physical shared storage hardware (HA one of course).
Hi VR38DETT,
Thanks for responding. The hosts will cater a domain controller (on each host), Web filtering software (Websense), Anti-Virus (McAfee ePO), WSUS and an Auditserver as of the moment. Is the Hyper-V Replica somewhat give "high availability" to VMs or Hyper-V
hosts? Also, is the cluster required in order to implement it? Haven't tried that but worth a try.

Hyper-v 2012 r2 slow throughputs on network / live migrations

Hi, maybe someone can point me in the right direction, I have 10 servers 5 Dell r210s and 5 Dell R320's, I have basically converted these servers to standalone hyper-v 2012 servers, so there is no clustering on any at the moment.
Each server is configured with 2 1Gb nics teamed via a virtual switch, now when I copt files between server 1 and 2 for example I see 100MBs throughput, but if I copy a file to server 3 at the same time the file copy load splits the 100MBs throughput between
the 2 copy processes. I was under the impression if I copied 2 files to 2 totally different servers the load would basically be split across the 2 nics effectively giving me 2Gbs throughput but this does not seem to be the case. I have played around with tcpip
large send offloads, jumbo packets, disabled vmq on the cards, they are broadcoms. :-( but it doesn't really seem to make a difference with all of these settings.
The other issue is If I live migrate a 12Gb vm machine running only 2gb ram, effectively just an o/s it takes between 15 to 20 minutes to migrate, I have played around with the advanced settings, smb, compression, tcpip not real game changers, BUT if I shut
town the vm and migrate it, it takes, just under 3 and a half minutes to move across.
I am really stumped here, I am busy in a test phase of hyper-v but cant find any definitive documents relating to this stuff.

Hi Mark,
The servers (hyper-v 2012 r2) are all basically configured with ssvmm2012R2 where they all have teamed 1Gb pNics, into a virtual switch, then there are vNics for the Vmcloud, live migration etc. The physical network is 2 Netgear Gs724T switches which
are interlinked and each servers 1st nic is plugged into the switch1 and the second nic is plugged into the switch2.See Below Image) The hyper-v port is set to independent Hyper-v load balancing.
The R320 servers are running raid 5 sas drives, the R210s have 1Tb drives mirrored. The servers all are using DAS storage, we have not moved to looking at using iscsi and san is out the question at the moment.
I am currently testing between 2x 320s and 2x R210s, I am not copying data to the vm's yets, I am basically testing the transfer between the actual hosts at the moment by copying a 4Gb file manually, After testing the live migrations I decided to test to
see the transfer rates between the servers first, I have been playing around with the offload settings and rss, what I don't understand is yesterday, the copy between the servers was running up to 228Mbs ie (using both nics) when copying
the file between the servers, and then a few hours later it only was copying at 50/60Mbs, but its now back at 113Mbs seemingly to be only using one nic.
I was under the impression if you copy a file between 2 servers the nicks could use the 2gb bandwidth, but after reading many posts they say only one nic, so how did the copies get up to 2Gb yesterday. Then again if you copy files between 3 servers, then
each copy would use one nic, basically giving you 2Gbs, but this is again not being seen.

Hyper-V 2012 R2 does not disable the protocols on the physical network adapter

Hello,
I have a problem with the creation of an external network in Hyper-V (2012 r2), when I create the external network does not want to share with the host, therefore I take the check to share it. Hyper-V on the network adapter "real" does not disable
all protocols, but active all inclusive TCP4 and 6.
How so?
I have 2 other servers with the same configuration and run regularly.
Thanks in advance

Hi Fabio,
"when I create the external network does not want to share with the host, therefore I take the check to share it. "
Based on my understanding ,after creating a external Vswitch the physical NIC will only have protocol "hyper-v external virtual switch " whatever we check "allow management operation...." or not .
Do you mean after you create the external Vswitch , the physical adapter still have another protocol ?
If yes , my suggestion is to remove the physical NIC from "device manager " , then restart server and reload the driver then create the external Vswitch again .

Hyper V 2012 network options

We are testing Hyper V 2012, and the networking options seem confusing.
I created a virtual external switch on the host, trunked vlans down to it from an upstream 3750, and created some VMs.
No problem there: the VMs were able to get outside, etc.
But what do the "private" and "internal" networks give me?
It is my understanding that neither private nor internal networks can communicate with subnets/networks outside the host(s)
I thought maybe I could use private networks and have the Hyper V 2012 host route the traffic out to the real world, apply security policies, etc.
Is this even possible? Or do the options simply isolate VMs? (and are therefore not any better of existing VMWare technology)

My understanding is that the private and internal networks are for networking specific to the hyper-v host. So you can create a private netwok that allows two VMs to communicate with each other but not the outside world.
There is no way to forward that traffic outside the hyper-v host.
We are working on N1KV for Hyper-v which will bring most of the NXOS feature set to Hyper-v. So PVLANs, ACLs, port-channels, QOS, etc...

Hyper-v 2012 R2 server core recommendations for single server setup

Hi All,
Next weekend I will be installing a brand new Dell 720 server for a client of mine.
I would like to hear some recommendations on how to install this hypervisor.
Let me state that I have had some experience with virtualization technology in the past with VMWARE ESXi.
This is a small client with under 10 users but I have learned that with the 2012 product offering you cannot get Small Business Server any more. I know Microsoft has Windows server 2012 Essentials but you would have to have Exchange server in the cloud which
my client does not want. He wants to run his Exchange server in house.
Also he needs Remote Desktop Services (Terminal Server) because his accounting application requires it.
He has an existing Windows 2003 domain controller that eventually has to be decommissioned because it is too old and slow.
So I thought I install Hyper-v 2012 R2 core on the new server and then create 2 VMs:
1) Windows 2012 STD to run as a secondary domain controller.
2) Windows 2012 STD member server with Exchange server 2013 and Remote Desktop Services role.
My questions here are these:
1) Do I install the Hypervisor in workgroup or domain mode?
2) When I am finished with the old server do I transfer the AD FSMO roles onto the VM that is acting as a domain controller?
The new server has 2 CPUs. How does Microsoft licensing go here? I know that Windows 2012 STD gives me 2 instances with the same product key on the same server for 1 CPU. What happens if you have 2?
Can someone give me some insight on how to go about this? I remember that I found this easier with VMWARE Esxi.
Now with Hyper-V I need to also get a management workstation with Windows 8 professional on it to manage the Hyper-V core server.
Thanks and regards
Alfred

In regard to the VM's:
1.) DC: If you're going to be installing a second domain controller that is 2012 R2, you might consider reading this guide first.
http://msmvps.com/blogs/mweber/archive/2012/07/30/upgrading-an-active-directory-domain-from-windows-server-2003-or-windows-server-2003-r2-to-windows-server-2012.aspx
2.) Exchange: Here's the guide for installing Exchange 2013 on Server 2012. I don't believe R2 is supported yet for 2013.
http://social.technet.microsoft.com/wiki/contents/articles/14506.how-to-install-exchange-2013-on-windows-server-2012.aspx
3.) Host: You'd install the host in domain mode....but that point may be moot after you read #5.
4.) FSMO: I would verify the health of the 2012 DC before moving the roles. All too often I'll see a new DC get stood up, sysvol won't be published, the engineer will be in a rush to move the FSMO's, and things get a little sideways. Ultimately
you don't HAVE to move the FSMO's until you are ready to decommission the 2003 box.
5.) Licensing: No licensing rights convey with Hyper-V Core, so this may not be best for your scenario. See the queen mother of all Hyper-V licensing posts here -
http://www.aidanfinn.com/?p=13090
For what it's worth, plenty of SMB's are going to Office 365 to avoid the on-prem administration headache, but your client wants what your client wants. Sorry if this isn't the news you wanted but I hope it helps.

Moving VMs From One Hyper-v 2012 R2 to Another Hyper-v 2012 R2

Hi everyone, was hoping for some help in something I am confused about
Currently I have SERVER1 running hyper-v 2012 R2
I want to move all my VMs (around 20) to SERVER2 also running Hyper-v 2012 R2
But I am confused on the best way to do this
1) should I just click on "MOVE" on SERVER1 to move to SERVER2?
2) Should I do an export and then import
3) should I setup replication from Server1 to Server2 and then do a failover?
4) or should I shut the VM down, copy the VHDX file and then create a new VM and use that VHDX
I just want to be cautious and use the best method to ensure it goes smooth and not worry about any corruption. Can anyone offer some advice?
thanks

It all depends on your environment and your current Hyper-V configuration.
I asume both servers are domain-member of the same domain and don't use SCVMM. If so, then make sure you do the following:
First enable the "Live Migration" feature in the Hyper-V settings on both Hyper-V Servers.
Make sure both Hyper-V Servers have a vSwitch configured with the same display name and connectivity. They must be somewhat identical, but not everything. As long as the connectivity is the same.
Make sure you have a location to store the VM files on SERVER2.
Then do a Live Migration from SERVER1 to SERVER2, follow the wizard. By using the Hyper-V Manager console on SERVER1.
NOTE1: Without computer certificates and Kerberos configuration on your Live Migration settings you cannot initiate a Live Migration from the Hyper-V Manager cconsole on SERVER2. With the default configuration, you have to login on (or connect
to) SERVER1 en then initiate the Live Migration.
NOTE2: If you can't configure the vSwitches the same. Then you have to shut down the VMs and do a Quick Migration. Then re-configure the VM network properties and power on the VMs.
I hope this information will help you goin on. If you need more detailed information use the following link:

Monitoring Hyper-V 2012 R2 - Performance Data/Graphs Equivalent to XenCenter/vSphere Client

Hello,
We've just moved away from Xenserver (hooray!) to Hyper-v 2012 R2, but I must admit the best thing about xenserver was xencenter. The ability to see the real time performance of a VM and see its network utlisation/CPU/Memory was very very useful. Also the
same for VMWare vsphere client.
Although Hyper-V 2012 R2 is a lot better than xenserver the realtime monitoring of VM's is awful!
We have SCVMM but that doesn't give you much either, only average CPU data..and only when it decides it will show the graph!
I've tried a few free tools, VMTurbo, Solarwinds VM Monitor (free - which doesn't support 2012 R2) plus some others...but none give us what we want.
I've seen all these other posts about monitoring reports etc which are all good and well but when you need real-time data how are people getting this? We don't want OM as we cannot afford it nor do we want the excess of managing it (not even sure if this
would give us what we want).
Can anyone give me ideas of what they are using for this or what products, I feel MS have messed up a bit here, if they had these features in Hyper-v Manager/Failover Cluster Manager then it would be on a par with VMWare for sure.
Many thanks
Matt

Update:
I've got a trail license of SCOM and installed it and connected to SCVMM (eventually...what a pain having to install extra packages etc!! good stuff MS! You'd think as SCVMM is part of the System Center family it would be easy to connect to SCOM)
I also got the free version of VeamOne as suggested by Leonardo.
SCOM is too complicated and requires far too much configuration just to get simple monitoring from Hyper-V and I really can't believe you need all this extra software just to get performance graphs from Hyper-V/VM's. Really don't want to install extra agents
on the hosts etc goes against Hyper-V best practice about keeping the servers light. Plus even trying to get simple data out of SCOM is tiresome.
VeamOne on the other hand...for a free product does exactly what SCVMM 'should' be doing.
Plus very useful extra info/alert that SCVMM doesn't even show up which I wasn't aware of, SCOM probably would show these alerts after you've spent days and days trying to figure out how to configure it and reading loads of articles.
So unless there is some hidden gem in SCVMM then it needs to be improved greatly on the monitoring side to fully compare with VMWare I believe as the idea of having to setup/configure SCOM just for monitoring is ridiculous.
I'm going to stick with VeamOne for now as its simple, gives me the info I require.

Hyper-V 2012 and TMG 2010/NLB

Hi there,
I have an issue with TMG 2010 on Hyper-V 2012 - the Setup:
- Windows 2012 Hyper-V
- TMG 2010 SP2 Rollup 4 running on W2K8 R2
TMG 2010 (Array Node1) Network
Internal Interface: 10.0.0.10/24 (Route to 192.168.11.0/24 over 10.0.0.1)
IntraArray: 192.168.10.10/24
Perimeter: 10.0.60.10/24 GW 10.0.60.100
TMG 2010 (Array Node2) Network
Internal Interface: 10.0.0.11/24 (Route to 192.168.11.0/24 over 10.0.0.1)
IntraArray: 192.168.10.11/24
Perimeter: 10.0.60.11/24 GW 10.0.60.100
Domain Controllers:
192.168.11.10
192.168.11.11
The NICs of the TMG VMs are configured with the correct VLANs and on the Perimeter Interface as well as on the Internal Interface I activate MAC Address Spoofing.
Once I activate NLB on the Perimeter Interface all works fine. But NLB on the internal Interface does not work - I see that NLB got configured on Array Node 1 but the second one does not get the config nor is able to sync it´s configuration with Array
Node 1. ALso the Servers are not able to communicate with the Domain Controllers anymore. Once I deactivate MAC Address Spoofing on the internal Interface and remove NLB the Server are able to speak to the Domain Controllers...
Any suggestions?

Hi,
Can I just confirm you are using TMG console to enable NLB?
Also did you enable set this reg key on both your TMG servers? You need to make sure MAC Spoofing is enabled too.
HKLM\System\CurrentControlSet\Services\TCPIP\Parameters
IPEnableRouter RegDword 1
after enabling the key you may need to reboot both nodes.

This is ABSOLUTELY RIDICULOUS. Canada still can't get it? Why does the US have access but not Canada. Can we expect it or is there another 3 month delay? Unbelievable that on day one I paid over $500 to buy this phone unlocked in Canada and still cannot use the most basic features like MMS. This is pathetic.

RDS - Issue using Windows 10 build 9926 as Virtual Desktop Infrastructure on Hyper-V 2012 R2

We currently have a production Windows 8.1 as a VDI/RDS on Hyper-V 2012 R2. On testing the last build of Windows 10 (98??) we had no issues deploying this in same RDS as pooled desktops.
The latest build 9926, although correctly sysprep-ed (either by removing AppX modern apps that have been updated, or not connecting the template to the internet), the build is only ever partially successful. Some VMs build others do not, and the ones that
build cannot be managed via RDS/Server Manager, functions such as logging a user off with server manager, result in an error. (WTS API failed)
Build Error on connection Broker - Microsoft-Windows-TerminalServices-SessionBroker
VM host [HOSTSERVER05] failed to execute VM Provisioning operation [Task: To perform post processing actions at VMHostAgent:] for virtual machine [VDI-W10-57] in pool [VDI_Advanced_Te], Error: [Error code: 0x88130221.]
Any guidance on how to troubleshoot this would be greatly appreciated, although I suspect something regarding the auto-deployment/unattend and management systems though RDS no longer works with the latest Windows 10 build.
Already posted this in the
Windows Insider Program site, but was asked to re-post here. Thanks

OK, I've carried out some more testing on the client site and have been able to move a couple of existing VMs from their 2008 R2 Hyper-V server to the new 2012 R2 server.
Both VMs are Windows 7 SP1 with the RDP 8.0 update installed and I can connect to them from a Thin Client running RDP 7.1 and a laptop running RDP 8.0.
When I add the RemoteFX vGPU to them both I can still connect from both devices but, as suggested, when connecting from the laptop with RDP 8.0 I don't get the vGPU performance (but the vGPU is still shown in the device manager).
It all looks good at the moment but I'm still concerned as to why I was unable to connect to the first VM I moved over (it was complaining about a error in the License network communication or similar).
I'll keep testing and post anything else that might be useful.
Cheers for now

SLES 10 (SP3) on Hyper-V 2012 R2

I do realize that is unsupported (only SP4 supposedly is)
But I have SLES 10 (SP3) image that got converted from vSphere
Once I can boot the IDE disk (by editing menu.lst to /hda1 & uninstall Vmware Tools, I would need to get network connectivity, so logical step would be to use Intergration Services 2.1 (one that supports SLES 10 SP3)
But it is a no go. On make install during load of vmbus the whole VM just hangs & dies
http://imageshack.com/a/img545/7339/16u1.jpg
The initrd never even gets created as it dies & reset is the only option
If I rem-out vmbus start in Makefile then I can get new kernel installed, but restulting kernel will panic on VM boot
Anybody has any clever idea how to get it working (if at all possible)
Seb

Getting this to work is going to be difficult. The older LIS 2.1 does not work with Hyper-V 2012 and 2012 R2 due to changes in Hyper-V itself. But you could probably get SLES 10 SP3 with LIS 2.1 working if you went back to the older Hyper-V
2008 R2.
You are correct that the LIS 3.4 package is created only for the Red Hat (and CentOS) distros. It will not work with SLES releases.
We've gotten occasional requests to get SLES 10 working on Hyper-V 2012 and 2012 R2, and we're in conversations with SUSE about creating a combination that works. But we don't have anything to announce about a timeline. When/if we get something
working, it will most likely be SLES 10 SP4, since that's the most up-to-date version from the SLES 10 series.

How to move from vmware ESXi 5.5 to Hyper-V 2012 R2 on same hardware?

I have Vmware ESXi 5.5 Update 1 with two disks, called RAID0 (3.6 TB) and RAID5 (10.9 TB).
I am tired of having to rebuild ESXi every sixty days for home use so I am planning on moving to Hyper-V, but I'm a little nervous. I don't have swing kit, so will have to repurpose my existing 1 year old quite powerful machine (Intel i7 32 Gb RAM two sets
of RAID storage internal), 3 NICs. Features I need from VMware are:
Ability to snapshot and revert to snapshot (running and stopped VM)
Ability to move VMs between my different storage areas (RAID0 and RAID5)
Ability to set up internal networks to the Hyper-V host so I can set up virtual labs on their own virtual networks
USB pass through to the VM
Auto start VMs with the host.
Auto shut down VMs with the host.
Templating of OSs - mainly Windows Server 2008 R2 and Windows Server 2012 R2, but also Centos 7. Can I convert my ESXi templates to Hyper-V?
Good performance from both Windows and Linux machines
Easy management from a workstation on the network.
Install Hyper-V to USB flash drive plugged in to the server.
Can Hyper-V do all that?
Also, I have a migration plan. Will this work?
In ESXi move all machines for migration from RAID5 to RAID0 storage.
Install Hyper-V on the host to USB flash drive (16 GB)
Format RAID5 storage so it can take vhds. (NTFS?)
Set up networks - have three NICs on the host.
Install management software on my workstation
Convert VMware vmx machines on RAID0 storage to vhd based machines on RAID5 storage. How to do this? My machines vary from v8,9 to vmx10.
Power on VMs and perform checks.
Any comments? I'm particularly concerned about the conversion process from VMware to Hyper-V and the reliability of it. Total size of VMs to convert is just under 3 TB.

Hi Mark. The short answer is yes to all. The more detailed answer is:
Make sure you're installing Windows 2012 R2 on the bare metal. All the following refers to 2012 R2.
I recommend you take some time and go through the
Hyper-V Best Practices Guide
Ability to snapshot and revert to snapshot (running and stopped VM) => yes, standard feature. Keep in mind this is meant to be a short term measure, not something you keep around for long time.
Ability to move VMs between my different storage areas (RAID0 and RAID5) => yes, storage migration is a standard feature that allows you to migrate a VM storage while the VM is running.
Ability to set up internal networks to the Hyper-V host so I can set up virtual labs on their own virtual networks => yes. An external vSwitch is one that's attached to a physical NIC. I recommend you review Hyper-V networking. It's a bit different than
VMWare.
USB pass through to the VM => not exactly. Some work around options exist, including sharing the USB drive on the host.
Auto start VMs with the host => yes, standard VM setting. You get to choose per VM whether to always start, start if it was already running, never start, or start with a given delay.
Auto shut down VMs with the host => yes (like save state) - defined in each VM setting
Templating of OSs - mainly Windows Server 2008 R2 and Windows Server 2012 R2, but also Centos 7. Can I convert my ESXi templates to Hyper-V => yes, native in VMM, plenty of Powershell examples available online. Manual steps in Hyper-V Manager to re-use a
sys-prepped OS image is also available.
Good performance from both Windows and Linux machines => yes, depends mostly on hardware
Easy management from a workstation on the network => yes, from a Win 8.1 workstation, install RSAT
Install Hyper-V to USB flash drive plugged in to the server => yes. 16 GB is a bit small. I recommend a pair of mirrored 128GB SATA SSDs - should be inexpensive.
In ESXi move all machines for migration from RAID5 to RAID0 storage => All you need for migration is the VMDK files for each VM. VM should be offline.
Install Hyper-V on the host to USB flash drive (16 GB) => see recommendation about a pair of boot SSDs above.
Format RAID5 storage so it can take vhds. (NTFS?) => yes, NTFS, 64KB allocation unit
Set up networks - have three NICs on the host => in a single host environment / lab, you'll use 1 NIC on a single external vSwitch I guess. Or you can NIC team them then attach vSwitch to team.
Install management software on my workstation => RSAT on Win 8.1
Convert VMware vmx machines on RAID0 storage to vhd based machines on RAID5 storage. How to do this? My machines vary from v8,9 to vmx10. => try
MVMC 3
Power on VMs and perform checks. => no comment :)
Did I mention the

Can't connect to the Hyper-V manager after upgrading to Windows Hyper-V 2012 R2

I have some Hyper-V server based on the free version (Windows Hyper-V 2012). I want to upgrade to the new version (Windows Hyper-V 2012 R2). So I begin to test it with
an already working server (aka I was able to totally manager the server remotely without problem) and so upgrade it to the R2.
After the upgrade, remote management and Hyper-V manager does not work anymore. So I redo my usual configuration steps (enable remote management, open firewall, uses
latest hvremote.wsf, etc.). I was able to regain access to Computer Manager but not the Hyper-V manager which still can't connect at all. I can't access the Task Scheduler too without having a lot of XML error like "The task XML contains a value which
is incorrectly formatted or out of range" (see below for screenshot).
Is there a new step to do to be able to manage Hyper-V 2012 R2 from a Windows 7 computer?
It's not a network problem as I can access RDP and MMC Computer Manager.
To be sure the problem is coming from the R2, I have taken an old computer, install Windows Hyper-V 2012, do my usual configuration step, and
tada: it works perfectly. I can access the Hyper-V manager from my client.
Technical details:
- Client is a Windows 7 SP1 x64 English member of a domain with latest RSAT (Windows6.1-KB958830-x64-RefreshPkg.msu).
- Servers are in a workgroup (not a domain's member). And no, I can't add them to the same domain as the client.

HI,
Can we upgrade HyperV 2012 to hyper v 2012 R2.
Thanks

Hi Ravi1987,
The KB2838043 is applied for Server 2012 node, Could you offer us the related cluster error event id, or you can refer the following article to check your cluster
network binding order is correct or not.
Configuring Windows Failover Cluster Networks
http://blogs.technet.com/b/askcore/archive/2014/02/20/configuring-windows-failover-cluster-networks.aspx
You can try to install recommended hotfixes and updates for Windows Server 2012 R2-based failover clusters first, then monitor this issue again.
