Hello,
For whatever reason I am confused on what is the best way to monitor performance on Hyper-V guest machines. So I have a few questions I am hoping that some of you experts can help me with.
Thanks for any input you may have.
Having an issue with my Hyper-V Core 2012 server as I plan to migrate my VMs to a MD3200i storage device. When I restarted the server after installing the two 4p Intel I350-t NIC cards, 7 of the 8 ports appear in Network Settings in sconfig.cmd. The 8th port isn't listed, just my original NIC team and 7 of the Intel ports. Using DevManView I can see all 8 ports and I've even tried to enable the selected device and still it doesn't appear in sconfig.cmd. I have tried a different cable to rule that out as well, but no luck. I have also tried connecting the 8th NIC slot to different ports on the MD3200i and have determined it is definitely not the MD3200i but the NIC port on the server.
What should I be looking at next as I can't seem to get his 1 port active and it's delaying me from moving forward with the MD3200i implementation?
Hello,
Way back in 2008 when we configured our virtualized datacenter (used Virtual Iron, now defunct) it was recommended practice to use identical iscsi cards for all hostnodes. We have since migrated to hyper-v 2008 r2, and are now moving on to hyper-v 2012 r2. We are currently spec'ing out a new hostnode, and I'm looking for advice on whether it's still the recommended practice to keep all iscsi cards as similar as possible.
The hosts will be connected to a MD3220i SAN.
The reason I'm asking is because we currently use Broadcom's 5709c's in all our hosts. They have had their problems, so I'd like to move away from them. Right now I have my eye on the Intel i350's. It's a choice between the two since those are the only affordable offers we have. I did a quick search online and found that Intel iscsi cards are much preferred over Broadcoms. It's not in our budget to switch out all existing cards with intel's, so I'm wondering if it's now considered relatively safe practice to let iscsi cards from different manufacturers play together, since the technology has become more mature. Any advice would be welcome.
Thanks in advance
Hi frineds
i am looking for a link or document to find out the limitations of hyper-v in windows 8.1 in comparison with windows 2012 R2. but i was unable to find a good link.
may someone please help ?

Dear Sir,
I am a new admin and have 5 Blade server "HP ProLiant BL660c Gen8".
I access these servers through HP enclosure.
I have to install Hyper-V on server 1 which consisted of the OS windows server 2012 R2 Datacenter edition.
I created a plan to create 5 Hyper-V VM's on the physical server and I requested the IT department network Admin that I want these 5 VM's to able to connect to each other.
The network Admin created a Trunking configuration on the physical server and after this setup he provided me Hyper-v node IP address and 5 more IP addresses for the 5 Hyper-v VM's.
Now it was left to me to Add the Hyper-v role and create 5 VM's.
While Adding the Hyper-V role, I was asked in the middle of the setup to add the network adapter for connecting to external network.
I went inside the network connection settings and I see one network adapter "Microsoft Multiplexer" which had the IP address of the Hyper-V node which was given to be me by Network Admin.
Besides this I found following Network Adapter: (Mgmt,Trunk):(Mgmt A, Trunk A);(Mgmt B, Trunk B) =Total 6 Network Adapter out of which only "Mgmt" was configured with the IP address of the Hyper-v node given by my Network Admin. Remaining all other Network adapters IPV4 configuration was unchecked except "Mgmt"
So I selected the "Mgmt" connection while Installing the Hyper-v role
SO I chose this Network connection for adding the Hyper-V role.
My question: Did I chose the correct Network Adapter.
After doing this I created a VM-1 and tried to assign the IP address given by the Network Admin. But the network Admin did not provide me the default gateway so I used the deafult gateway according to the IP address and used the last digit as "1" like a general installation.
Now my question is: 1.How can I use this VM to be used as a Virtual server?
2. I would like to open this VM through my browser by entering the IP address of this VM-1. How can I do this?
Because I access my physical server through the IP address. SO in the similar way I want to access this VM-1 through the IP address OR is there any alternate way to access this VM-1 separately.
My Requirement: I need to give VM-1 access to another admin to Install his application on it. SO how to give him to access this VM directly?
This is my main query.
Waiting for your reply.
Thanks & Regards,
Ahmed
I have a development environment on Hyper-v i want to be able to develop windows phone apps for this i need a Hyper v installation on my dev environment so i installed Hyper-v.
But if i start debuging the virtual hyper v says : The Virtual Machine Management Service failed to start the virtual machine 'Emulator 8.1 WVGA 4 inch.administrator' because one of the Hyper-V components is not running (Virtual machine ID)
can anybody help me out on this one as it looks all good. If i try to start the hyper v machine within hyper v i get the same error.
thanks in advance.

I currently have 1 physical server with Server 2012 R2 Essentials, running Windows Server Backup to external HDD. Is there anyway to use this backup to rebuild the server onto new hardware with Hyper-V?
I've installed Server 2012 with Hyper-V on to the new hardware, booted a VM from an ISO on a USB and tried "Repair your computer" with the backup HDD attached but can't locate the system image. Am I missing something really simple?
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

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.
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!

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,
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
i installed windows server 2k12 r2 and i installed audio driver is successfully installed and trying to install lan driver intel 82579 but unable to install error coming no network adopter present ..
Kindly Help me as soon as possible

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?
Regards Perry
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

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
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?
