Ah, for the good old days...

In the good old days we'd simply:

1. Install two NICs in our server box
2. Call one external and the other internal
3. Cable the backside of our DSL router to the external NIC
4. Cable the internal NIC to our switch
5. Cable our switch out to the workstations

Simple stuff, really. Small single-office network, 10 workstations.

How on earth to accomplish this on a Dell T420 w/dual-port NIC running Server 2012 Essentials in a VM on Hyper-V 2012?

I'm absolutely lost. For hours now I'm wading neck-deep in highly complex documentation that tells me how to design and build a nuclear-propelled craft for flying to Saturn using same, along with plenty of helpful blogs and advice for Server 2008, but I'm turning up nothing that applies directly to what I'm trying to do on the new stuff. Odd. I'd have thought my setup was just about as simple and standard as one could get, but apparently not.

Any kind assistance available? Even the not-so-kind kind would be appreciated at this point. This is starting to hurt.

Thanks,
Jeff Bowman

This is about setting up multiple subnets under a domain. If needed there is a little bit of history at http://social.technet.microsoft.com/Forums/en-US/winserverhyperv/thread/f6e6af61-ae5a-4d0d-a9a5-79faf5261790

Where its failing now is at the time when the machines on seperate subnets are placed on different private networks. Here is a chart for where ping requests are failing (icmp/firewall have been enabled/turned off)

The ip assigned to the machine are as listed below

Host	Card	Network	IP	Subnet	Gateway	PrefferedDNS	AlternateDNS
WnDC	Nic1	Public	192.168.1.1	255.255.255.0	192.168.1.254	127.0.0.1	92.68.1.1

Hi there,

I have two Hyper V servers, the first is Windows Server 2012 with Hyper V and the second is Hyper V Server 2012 (bare metal installation). I have setup replication from the Windows Server 2012 to the Hyper V Server 2012 and it works fine. However, I cannot replicate from the Hyper V Server 2012 to the Windows Server 2012. I noticed that the core installation does not have Hyper V Replica Service in the Kerberos Delegation tab as well as the pre-defined Hyper V listener port in the firewall.

Any thoughts???

Hi!

I dont know if this is the right forum but i will try here!

 

I am about to buy a new computer and i'm intending to use it to virtualize a lot of servers/clients, to set up a test LAB. I have come to the choice of memory!

My motherboard supports memory speed up to 2400MHz but they are so Freaking expensive! 32GB of 2400MHZ memory costs just as much as 64GB of 1600MHz.

So is it worth it? Does it make a big difference when virtualizing? I know that you need fast memory when working with video rendering and you dont need it for example gaming, but how is it with virtualization? Anyone know?

 

Thanks!

I have installed R2 and the Hyper-V component, virtualization is enabled in the BIOS.  My problem is there is no "New" option in the Action Pane of the Hyper-V Manager. 
 
My version of R2 Enterprise installed is 64 bit and off the disk that comes with the MCITP Server 2008 Enterprise Core Training Kit put out by Microsoft.  My laptop is an HP dv7-3085dx (http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01896913&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&product=4041797&lang=en).  The server software is the one and only active OS partition on the hard drive.

Anyone have any thoughts?

Hello,

i installed on DELL R620 windows server 2012 STD and add the hyper-v role

when i created a virtual switch , the speed of network in the HOST( the server itself) is ver poor ( copy file from fileserver is 300Kbs)

when i remove the virtual switch , the speed of the network is better(  copy file from fileserver is 10-20Mbps)

i spoke with DELL support center , and after check up , no problem has found.

i tried all the chnges with the offload checksum etc but nothing helped

Please your comment about this issue

Thanks

I have 5 vms, 4 using dynamic vhds and 1 using iscsi passthrough drive.

For all 4 dynamic vhd vms i am getting above error.

There is no snapshot taken for any of this vms

Also server 2008 r2 is upgrade from 2008 fyi

Anyone could please help me figureout what's wrong in there?

Hi I am trying to understand if hyoper v can do this:

I am currently using a software called ccboot to pxe boot thin clients and non hard disks pc to a vm (vmdk file) within a server, I need a more robust solution to this can hyper v do this?

Where can I get resources for example to upload guest os to the server and then run in pxe?

Hi,

I have a Windows 2012 Standard with Hyper-V role enabled and data deduplication on the hard drive. I have a lot of free space left on my hard drive (more than 50% of the capacity) but every now and then I will find half of my VMs in paused state with an indication that they were running low on disk space. I am confused as to why this error comes up specially when all hard drives have plenty of space left. Thoughts?

Hi,

I've been testing Hyper-V Replica in a Server 2012 Hyper-V Cluster. I have configured the replica broker on the cluster and enabled replication on the various servers and replication to my DR site seems to be working fine. Planned failovers work as expected.

When I came to testing a disaster scenario i hit a little snag. when the two cluster nodes (of a two node cluster) get forced off, I go to the replica server and go to the replication options of my VM and click failover, it does it's thing and comes online. so far so good.

Now, when the primary node comes online again Auto start kicks all the VM's into life so I end up with two versions of the same VM running on the network, one on the primary server and one on the replica server.

if I turn off auto start then it all works well, i reverse the replication and then fail back over so the cluster node becomes the Primary node again.

Problem with turning off Auto Start is that when one cluster node fails and the VM fails over to the second node the VM is left switched off because auto start is not allowing the VM to be turned on.

I would like to be able to leave auto start on because if a node fails at 3am I would like the VM's to start up again on the other node but i cannot leave the possibility of two versions of the same machines running at the same time.

Is there a way to configure the cluster and Hyper-V replica so the cluster knows when a replica version of its VM's is in operation? or could someone clear up any confusion i may have regarding how this is supposed to work?

I know the obvious answer is to shut down the replica VM's before i bring the primary nodes back online but I would need to verify that the nodes have been fixed and work properly first, I would also need to reverse the replication so the failed cluster VM's get the changes since the replica has been active before i bring the cluster version online again right?

Thanks :)

Never had this problem before, but today am installing some new windows 2008 R2 Standard VM's and I have no mouse control.

says mouse not captured in remote desktop session.

obviously I cannot install integration services as there is no OS installed yet.

I can connect to any exisitng VM, and mouse control works fine, the issue is only occurring when trying to install window son to a new VM.
I presume integration services is supposed to be loaded by the installer.

Normally I only install Web edition and never had this issue before.

Hi,

I have 2 test servers which are in the same domain. I want to use kerberos authentication but I am getting same error all the time.

The error is: Hyper-v failed to authenticate using kerberos authentication. The specified target is unknown or unreachable (0x80090303). Hyper-v failed to authenticate the replica server using kerberos.I can ping both name and ip. Dont know why is it unreachable.

This is strange because they are in the same domain. When I test this first time i didnt have problems with it.

Hope that someone can help with this.

My DC is Small Business server and maybe is because of that or.

Best regards/kaktak

Hi all,

I'm trying to understand the concepts and details of resource pools in Hyper-V in Windows Server 2012. It seems as if there is almost no documentation on all that. Perhaps somebody can support me here, maybe I've not seen some docs yet.

So far, I learned that resource pools in their current implementation serve mainly for metering purposes. You can create pools per tenant and then group VM resources into those pools to facilitate resource metering per tenant. That is, you enable metering once per pool and get all the data necessary to bill that one customer for all their resources (without metering individual VMs). Is that correct?

Furthermore, it seems to me that an ethernet pool goes one step further by providing an abstraction level for virtual switches. As far as I've understood you can add multiple vSwitches to a pool and then connect a VM to the pool. Hyper-V then decides which actual switch to use. This may be handy in a multi-host environment if vSwitches on different hosts use different names although they connect to the same network. Is that correct?

So - talking about actually managing that stuff I've learned how to create a pool and how to add VHD locations and virtual switches to a pool. Enabling resource metering for a pool then collects usage data from all the resources inside that pool.

But now: I can create a pool for memory and a pool for CPU. But I cannot add resources to those. Neither can I add a complete VM to a pool. Now I'm launching a VM that belongs to a customer whose resources I'm metering. How will Hyper-V know that it's supposed to collect data on CPU and memory usage for that VM?

Am I missing something here? Or is pool-based metering only good for ethernet and VHD resources, and CPU and memory still need to be metered per VM?

Thanks for clarification,

Nils

Hi guys,

This question is for Hyper-V 3.0

I run Hyper-V on Windows Server 2012. The physical server has two NICs (one for public vlan, the other for the private vlan). Since installing the Hyper-V role on the server, I have a virtual NIC in network apdaters on control panel.

On the virtual switch settings, which NIC should I use? I assume the private adapter. Also, which type of network should this be?

When attempting a Shared Nothing Live Migration, I recieve this generic error:

I have looked in the event logs on both the target and destination server, and have found nothing more specific than this.

The source server (PHOEBE) and the target server (SATURN) are on the same domain.

My user account is in the Domain Admins group.

I am using Kerberos Authentication (and have configured Constrained Delegation) - although I have tried CredSSP (logged in to the source server), and had the same error.

All other posts I have seen show specific errors (such as Access Denied).  Any thoughts on troubleshooting this?
