Hello Community
If you have 7 Servers (named "Server1" ... "Server7") all running WS2012 R2 server Standard Edition,
which you get to create 2 Virtual Machines (using Hyper-V) at no extra cost.
The question is:
Knowing that each server has its own IP address and may even be on a different subnet(s)
or the same subnet, if you create 2 virtual machines on (for example) "Server3" will those virtual
machines be able to run on any of the other 6 servers?
Thank you

Complete Scenario:
We have IBM Blade S having three computes named as CS1 , CS2 , CS3 each computes installed with Windows Server 2012 R2 Hyper-V Roles with different VM Machines (Windows Based + Linux) placed at ISP Rack the link between our Head Office and ISP Rack is
on Layer -2 Dedicated 6 Mbps.
On three of virtual Machines Oracle EBS 11g is running, operating system is (Linux Oracle Unbreakable 6.5) named as ERP, ERPTest, ERPDev
Issue:
Now I want to enable workflow mailer service (SMTP Service) on ERP for users to receive emails but when we enable workflow mailer service (SMTP Service) the link between our Head Office and ISP Rack goes down and we are not able to ping any IP of VM of IBM
Blade S and there VM’s.
Now when I do above same thing on ERPtest and ERPDev VM nothing happened the links works fine.
Hi, not sure if this is a right forum, but anyway...
A small organisation is buying a server from OEM (say, called SERVER1) and can request to add some software licenses, but doesn't know which ones. The aim is to make it possible for 5-10 users of this organisation to have their own virtual workstations based on Windows 7 Professional, and all virtual machines running on that server -- SERVER1. Each of 5-10 users needs to have their own workstation (1 to 1), with their own OSE, windows updates, set of applications, etc whatever is needed. The users plan to access their own assigned workstation by RDP from the same organisation's OEM PCs, but some from thin clients.
What Microsoft licenses need to be purchased?
Hi all,
I have an hyper-v install with a dell T320 server with two ethernet cards from Broadcom and Windows Server 2012 R2 as hyper-v server.
I have one VM with 2012 R2 and one another host with 2012 Std. All the systems are working fine since we make the install.
Since this morning I see that the 2012 Std server is not able to connect to the network.
I shutdown all VMs, delete the Vswitch, delete the physical network card, restart the host, recreate a new vswitch and reconnect the VMs to it. I access the network on 2012 R2 but in 2012 Std the OS see no network card.
What can I do.
Hello.
I wonder if anyone can help me. I have a 2012 server (not R2) running Hyper-V. There are 4 VMs on the host, 2 are Server 2008 and 2 are Server 2003 (SP2). The Best Practices Analyzer tells me that dynamic memory is not running correctly as there is a mismatch in the versions of Integrated Services on the VMs. Looking into this (I am new to this setup) I found that both the 2008 machines have IS versions 6.2.9200.16433 and both the 2003 VMs are still on 6.2.9200.16384.
I tried to update the 2003 VMs by extracting the GuestVMs.iso content to a shared folder and installing on the VMs but all I get is a message saying 'this computer is already running the current version of integration services' with 6.2.9200.16384. Which isn't the latest version. I did the same thing on a totally seperate server with 2012 VMs and it updated Integration Services so I know the procedure (and the .iso content) is valid.
Is it just the case that Server 2003 cannot handle any IS version higher than 16384? If so I wish I could find somewhere that says that! Or is there something else I can try?
All suggestions gratefully received!

Hello,
I have a Windows 2012 R2 Server running HyperV. The moment i create a external Vswitch from the Virtual Switch Manager, i loose connectivity from the host machine. I then have to manually go back and delete the vswitch to have connectivity again. Is this a bug ? Couldnt find any hot fix for it. What am i missing ? The network connection for the vswitch is out of a DHCP scope block.
I have a physical host running Windows Server 2008 R2. I have 3 VM's with the same OS running inside of Hyper-V. The host has two NICs. The host NIC is configured on one VLAN.
I have created an external switch within Hyper-V and connected it to 2nd physical NIC as the 1st physical NIC is dedicated to the host. When I do this the properties of the 2nd physical NIC change to only have the "Microsoft Virtual Network Switch Protocol" enabled. I then configured the VNIC which Hyper-V creates on the host to point to the VLAN dedicated for my virtual machines.
Essentially, I have two physical NICs. One pointing the host the one VLAN. The other pointing my VM's to another VLAN. My question is -- do I give the VNIC an IP in the VLAN for my VMs? My second question is do I configure the "Microsoft Virtual Machine BUs Network Adapters" on the VM's themselves by giving them IPs in the VLAN and DNS servers or do they obtain that information from the VNIC that is created on the host by the external switch. This is confusing.
Again - in an attempt to keep it simple -- I have two NICS. One dedicated to the host and on dedicated to two VM's in Hyper-V. The VM's need internet access and need to talk to the host so I have set up an external switch and pointed it at the 2nd physical NIC. What should I do from there to achieve this?
Hi,
Before i describe the problem, here is an simplified overview of our environment:
We have an Windows 2012 R2 Hyper-V cluster with 8 nodes (HP Servers). Each nodes, is connected to two HP switch (5406zl) via 2x 10Gbe connections (dual port NC523SFP 10Gbe NICs). The NICs are in a switch independent team, on top of which we created a virtual
switch. Connected to the virtual switch, we have several virtual NICs (Management, Live Migration, Storage, Cluster).
The virtual machines running on the cluster are using SMB3 to connect to a scale-out file server who has 2 nodes. Each node also has 2x 10Gbe NICs (NC523SFP) which are in a LACP team. The virtual Machines configuration and virtual disks are located on the scale-out
file server disks and access via two shares.
Here is the problem:
Looking at the disk performance on the virtual machines, we get very bad response times (between 200ms and 500ms). After many days of troubleshooting, I have found that by removing the "QoS Packet Scheduler" from the virtual NICs (untick the box),
the performance goes back to normal and I get disk response times of 2-5ms.
I've tried to upgrade the driver and firmware on the NICs to the latest version, and also have applied all windows updates on the Hyper-V hosts and file cluster nodes.
I've also tried to remove the NIC teaming on the Hyper-V host, only using one of the 10Gbe card as a simple Hyper-V switch (without virtual NIC), but the same problem occurs.
I realize this is probably an HP NIC driver issue (I have a call open with HP support on this), but I thought, while I wait for HP to get back to me, I'd post the question here in case someone experienced the same problem.
Thank you,
Stephane
Hello!
There're three host computers in my test lab - Host1, Host2 and Host3.
Host3 has three physical nics, two of them are used for Hyper-V - there's a virtual machine namedFW with the nic = 10.10.0.101 (connected to the production network) and nic2 =20.1.1.1 - this nic2 is a default gateway for the test network 20.1.1.0/24 (consisting of several virtual machines hosted on Host1/Host2/Host3).
Host1 has three physical nics, the two of them are members of the team (VM-TEAM):
Virtual machine DC (hosted on Host1) uses the VM-TEAM as its network adapter with the ip = 20.1.1.2
Vm FW and vm DC are connected to the same 5-port 1Gb switch:FW is connected by the single utp5 cable, DC - by the two cables.
The problem: when coping any data from DC to FW (or vice versa) copy process stops after several seconds, then after ~10-60 seconds proceeds, then stops again and etc...
This problem has never arisen when I was using a SINGLE nic for the Hyper-V, NOT teamed adapters.
Are there any settings/known issues for the nic teaming that could lead to such problem?
Thank you in advance,
Michael
The hardware:
We have an 8 node cluster hyper-v 2012r2, All servers are the same, Dell PowerEdge 630
with 4 integrated NIC's 2x10 GB and 2x1GB (BCM57800).
They have also a converged network adapter(BCM57810) with 2x10GB ports and we use NPAR to devide it in 8 Nic's
So the Nic’s are configured like this:
Two on-board nic’s 1 GB are disabled
Two on-board nic’s 10 GB are in a team and used for the Host (NODE_NIC1 + NODE_NIC2 = NODE_TEAM)
Teaming mode LACP, Dynamic, all active, vlan default
VM_TEAM
Two NPAR nic’s (shared) 10 GB are in a team for VM_lan (VM_NIC1 + vm_NIC2 = vm_TEAM)
Teaming mode Switch independent, Dynamic, all active, vlan default
X_TEAM
Two NPAR nics (shared) 10 GB are in a team for VM_lan (X_NIC1 + X_NIC2 = X_TEAM)
Teaming mode Switch independent, Dynamic, all active, vlan default
Y_TEAM
Two NPAR nics (shared) 10 GB are in a team for VM_lan (y_NIC1 + y_NIC2 = y_TEAM)
Teaming mode Switch independent, Dynamic, all active, vlan default
One NPAR nics (shared) 10 GB -> iscsi_nic1 no teaming -> only virtual switch
One NPAR nics (shared) 10 GB -> iscsi_nic2 no teaming -> only virtual switch
The problem:
Virtual machines are running fine and suddenly they lose connection, it happens with all the teams except the Node_team.
We can reproduce it by moving the VM's around the cluster. If we disable or standby one adapter in the team, the problem is gone.
We have read a lot about VMQ, and we believe also that we hit something like that, but we cannot create the perfect solution.
And we would like to use the above configuration, as a workaround we use a active/standby nic in the team.
Any suggestions?

Hello,
I know there are articles online which provide helpful hits regarding upgrading a Hyper-V cluster to Windows Server 2012 R2 x64 but I would like to your advice for my environment.
I currently have 4 Hypervisors configured in a Failover Cluster setup. I now have another server of the same model and type (R720) which I will be upgrading to Windows Server 2012 R2 x64 since it has never been applied to the Hyper-V cluster (I have no idea why my predecessor left it hanging).
The virtual machines are stored on my Dell Compellent which is connected to the Hyper-V cluster via fiber (10GB network speeds).
My question is:
1. Can I upgrade the Hyper-V cluster to Windows Server 2012 R2 x64 without having to re-install the entire system and start from scratch? I would shutdown all VMs prior to this. This will not affect production as I will be making these changes in the summer when classes are not in session.
2. What would the problems be, if any, if I were to upgrade each Hyper-V host without re-installing the entire system?
I look forward to hearing from you and thanks in advance,

Hi there,
Regarding Server 2012r2 as a guest OS on Hyper V 2008r2, I've read the official Microsoft position and understand that Server 2012r2 is an unsupported guest operating system. However has anyone had any issues running with this setup. We have around 30 2012r2 VM's running quite happily on our Hyper V 2008r2 environment and before I add any more I'd like to know if there are any issues out there.
Thanks

We have a windows server 2012 as a hyper v host and 2 VM S SBS 2011 and windows 7 VM
Since this Tuesday the CPU usage is a constant 100% on both VMs and since backups were failing due to high cpu usage rebooted the SBS 2011 server. But even after a reboot/shutdown SBS is at a constant 100% usage
We disabled all non MS services, disabled Exchange, SQL and memory hungry services but the CPU usage is at a 100%.The time it goes down is when we stop all MS /NON MSservices except bare minimal services which needs to run the SBS properly
Even with this the moment we open up a MMC console , open up an application on the server the cpu goes to 10% and remains for a long time and then goes down again
But with all SBS services running it never happens and stays at a 100% even after acouple of hours
Hyper V integration services are up-to-date
Any advice is greatly appreciated.
Thanks

I'm using Hyper-V on a Windows 2012 R2 system. The system has a Intel Core i7-4700MQ processor. I created a VM running Windows Server 2008 with 4 processors and no limit to system use (or so I thought). The VM seemed to be taking a long time to install updates. I ran perfmon on the VM and it showed 2 processors averaging 30% and the other 2 around 14%. All four were hitting 100% at times. But when I ran perfmon on the server it was averaging 3% and maxing out at 18%. I only had the one VM running. Is there some way to get the VM to use the system resources more effectively?
I am building an MCSA lab in Hyper-V on my Windows 8.1 PC. I have 2 physical NICs on the PC with 1 NIC for Hyper-V and the other for the host PC LAN/Internet traffic. Physical network is 192.168.0.0 with gateway 0.254. Two virtual NICs were created on my host PC with the v-switches and I renamed them to "vEthernet (LAN 10)" and "vEthernet (LAN 20)".
In Hyper-V I have an external v-switch ("Hyper-V External") connected to the dedicated Hyper-V NIC and two internal v-switches ("LAN 10" and "LAN 20"), all are being used with
a virtual VyOS router for 2 separate LANs and a route to the physical network. This all works as desired.
On LAN 10 I have a domain controller ("DC1") at 10.100 that is running DNS and DHCP. When I enabled DHCP, "vEthernet (LAN10)" on my host PC pulled DHCP with a 10.254 gateway and a 10.100 DNS as I would expect but I noticed that when I shutdown DC1 I could no longer get to the Internet on my host until I disabled "LAN 10".
Doing a tracert from my host I found that traffic is being routed to the "LAN 10" gateway on the VyOS router first (10.254) and then to the physical router (0.254) and route print shows a route with gateway 10.254 with a metric of only 5 so that all traffic from my host is being routed through the virtual "LAN 10" interface rather than the physical "Ethernet" interface. I can delete the route to 10.254 and my first hop then becomes the physical router at 0.254 but if I disable and re-enable "LAN 10" the route to 10.254 with metric 5 comes back. Additionally, nslookup on my host defaults to 10.100 ("DC1"). If I disable "LAN 10" it will then default back to the DNS I statically assigned to my "Ethernet" NIC.
For now I'm just leaving the "LAN 10" interface disabled which doesn't affect VM network communication at all, it just keeps LAN 10 off my physical PC. I couldn't ping or RDP into VMs on that network from my host until I added a static route on my physical router to the VyOS router. This works but I don't get DNS resolution from anything on that network.
Should I just leave LAN 10 disabled or is there something I've overlooked that I need to (re)configure? I tried to change the metric of the default route to 0.254 from "266" to "4" but it will not go lower than 14. I would also like to know why it behaves this way - why are the virtual NIC settings given priority over the physical NIC settings? Is a NIC pointing to a domain given precedence over a NIC on a workgroup?
Thanks!

Hello,
Where do I download a Windows Server 2012 R2 Standard .iso from, for use with Hyper-v?
The only official download I can find is the evaluation version from here:
http://www.microsoft.com/en-us/evalcenter/evaluate-windows-server-2012-r2
Is it recommended to use the evaluation version and then license it to make it a full version, or is there a better official download?
Thanks
Paul
Windows 2012 r2 Hyper-V Dell R710 starts up in safe mode fine but with normal startup it comes to logon and after authenticating powers down. I suspect some UPS software installed on the host machine just before this started is the fault. I have a Windows 2012 R2 Essentials server and one Windows 8.1 Pro running perfectly as guests and I do have a full Altaro backup of the guests.
Is there a way I can come up as command prompt and then see what programs are on the host and delete them? I can get to Command prompt only but don't know how to get to programs to remove. Thanks

Have some VMware experience but new to Hyper V. Have a new Server 2012 R2 server and enabled the Hyper V Role so I can have a test platform to learn Hyper V on. Have a question about Best Practices for installing Guest OS due to conflicting information on docs I have researched.
Doc I read says that it is best to choose option to install OS later when creating the VM and also to use fixed VHDX files. Choosing to install OS later during VM creation results in a dynamic VHDX, a SCSI Controller, and an OS Not Found error upon initial boot. Have figured out how to get VM to look to ISO image during boot and install to hard drive on SCSI Controller. Have also figured out how to create hard drive VHDX file as fixed ahead of time and point that file during VM creation.
Choosing to install OS from an ISO image during VM creation results in a dynamic VHDX but now on an IDE Controller.
Which is the best way to install OS? During or later?
As far as Hyper V goes best to use SCSI or IDE?
If I have an IDE drive with an OS already installed can I convert to SCSI or vice versa? Have tried going into Hard Drive settings and changing from IDE(0) to SCSI(0) but end up with a boot failure. Changing back and all works fine.
Any and all input is appreciated - remember I am learning so will absorb and appreciate all input.
