Hi,
I'm installing Windows Server 2012 and Hyper-V on it. It is going to run two virtual machines (Server 2012 and Server 2008 R2). Should I enable data deduplication in host machine to disk where the virtual machines are or should I just enable deduplication to this 2012 VM that is a File Server?
Hi Guys,
In Microsoft Windows Server 2008 R2 i am installing hyper-v role,After that i have a plan to install three clients which going to run by same OS,
My Question is about?
How the Licences will be available to these three clients whether it wiil take a licence virtually from the parent Hyper-V sever or else wee need to provide the licence separately to these clients.

When installing SBS 2011 + Premium Add-on, I tend to deploy Hyper-V Bare Metal, then virtualize the SBS and Premium on two virtual Servers as some clients have a second Server to host Backup Exec to backup to an LTO or similar device.
We are wanting to consolidate an install to just one physical Server. I realise it is possible (and supported) to:
1) Install the Premium Add-On as a phyiscal configuration (base OS) with no roles enabled.
2) Install the Hyper-V Role.
3) Virtualize both the SBS and Premium Add-On.
But my main question is, would it be within the licensing agreement to host the Backup Exec Software on the phyiscal base OS to allow us to add a SCSI or USB backup device to simply back up both virtual Servers? I can't see this being a problem as
it doesn't breach the rules on adding roles/services within the OS itself, but simply allowing to back things up.
Thanks,
Luke
HI All,
I have a couple questions relating to a Hyper-V setup i am looking at currently. Everything is working good just looking to make sure its as good as it could be.
HP ML150G6 (2x 5504 Xeon, 32GB Ram, 6x 450GB 15K Raid 10)
Runs 2 hyper-v guests;
1x 2008R2 with DC, File/Print/ Exchange/ typical SBS functions.
1x 2008R2 RDS with about 15 users doing mainly MS Office work.
-My first question relates to the allocation of logical processors. The Xeon 5504 are quad-core NON hyper-threaded cpu's. Currently I have the CPU over allocated giving each guest 4 logical processors. Can someone please recommend a good split between these operating systems. currently the setup is only in the Lab with minimal load and everything is running very good. Minaly wondering if i should drop the DC to 2 logical processors instead of 4.
-I have both guests configure for dynamic memory. The DC starts with 4GB and the RDS with 512MB with 20% buffer. Is a 20% buffer recommended for RDS environment?
- Is it possible, and or recommended to use the same pass through disk for both guests? The disk will only be used for backup distination for each guest.
- Though not the correct forum i can't see one for Licensing.
If i have this setup with DC, exchange, RDS and 15 users what CALS with be required. I will be using Per User CALS.
15 User RDS CALs
15 Server CALS
Exchange CALS required or does Server CALS handle this?
Any others?
Thank you for your time. Also I did search these topics and got good infomation though i wanted a more specific answer taking these CPU's into account and also possible changes to best practice.
I run Windows Server 2012 RTM Hyper-V and I can occasionally not access the second virtual hard drive (dynamically expanding VHDX) attached to the VM through the virtual SCSI controller. I can however access the first hard drive that is connected with the virtual IDE controller.
I get the following warning in the event log under “Administrative Events” every 30 seconds when this happens:
I get this error once or twice a week and it has caused serious problems since one of the virtual servers that have this problem is a fileserver and the second hard drive contains all the data.
The only quick solution to the problem that I have found is to force the virtual machine to stop using the “Turn Off” feature since a normal shut down does not work (stops at shutting down the event log or similar) and then start the virtual machine again.
You can also wait for about 30 minutes or longer until the disk for some reason becomes accessible again by itself.
My research into this problem shows that:
I have now attached the second virtual hard drive to the virtual IDE controller to see if this permanently fixes this problem (i.e. does not happen for at least a week).
Is there something wrong with the virtual SCSI controller or the virtual SCSI device driver that comes with Windows Server 2012 RTM? Does anyone else have this problem?
Hello,
I am running Exchange 2010 in a virtual environment.
An associate of mine took a shapshot of this server using Hyper V back in February. He is no longer working for us. Is it safe to delete this snapshot and power down the server even though there is only 25GB left on the hard disc?
Ive seen were a merge could chew up lost of GBs in no time and then the merge will never complete.
Hi folks,
I have two Dell R-170 servers both running Server 2008 R2 and Hyper -V, each with two VM's installed and running. One of the physical servers is beginning to run low on disk space. I would like to move one of my VM's (about a 200Gb .vhd) from one server to another, so I will havce 3 VM's on one server and only one on the other at least temporarily. Likely I will move a smaller one from the one machine to the other later on to balance them out.
Anyway, the VM I want to move is a SBS 2008 server, which is running Exchange and is the DC for the domain. Any special considerations based upon that information?
I want to make sure I do the right steps to properly move that VM from one physical server to the other and have it come back online smoothly. Can someone point me to the proper steps to take? Here is what I think they are, but I'm not 100% sure.
Shutdown the VM on the current physical server.
Copy the VM's .vhd file to either an external drive or network copy to the new physical server.
Create the VM in Hyper-V on the new server, get the network configured (Can you copy the settings from the old host?)
Boot the VM on the new server and it should work now?
Tell the VM on the old server to not restart except manually, then after verifying all is working well on the new host, delete the VM and the .vhd file to recapture disk space.
Can someone point me in the right direction to do this properly. Since it's my DC and my Exchange server I really want to do this right the first time.
Thanks!
We have two identical Dell PowerEdge T410's running Windows Server 2012 Standard running as Hyper-V Hosts (and nothing else).
The Hyper-V guests on one of the machines take over 40 minutes to boot. Once booted the VM's seem to perform well. The second T410 is running without any problems.
The Dell has 40Gb RAM and has 12 virtuals, the 5 XP virtuals are running with 1 GB RAM each and the 7 Windows 7 VM's have 2 Gb.
When everything is running, the Dell's task manager says it's using 22.9 of 40Gb RAM and the CPU is ticking over at 1 or 2%.
I've just wiped and re-installed the host with a clean Windows Server 2012 with no improvement.
Dell's technical support has had a quick look and can't see anything wrong with the hardware side of things. The BIOS settings in the problematic machine has exactly the same settings as the BIOS in the machine that is working OK.
The clients on the 'slow' host are all part of a domain with the domain controller on the 'good' host. Tracert and ipconfig all report as expected.
A 'Google' has turned up a couple of articles which seem to only refer to Windows Server 2008 R2, however, the problem only started to appear when I installed Server 2012.
So, in a nutshell, two identical servers, the guests on one are working fine, the guests on the other take over 40 minutes to boot.
Could anyone give me any pointers?

I have a Server 2008 64bit physical server that I am trying to convert to a Hyper-V VM. I used disk2vhd from Microsoft to create the VM. When I try to start the VM on a Server 2012 host I get the message "Boot failure. Reboot and Select proper Boot device or Insert Boot Media in selected Boot device"
Any suggestions as to how to make the created VM boot?
Hi,
I have a question related to performance of cluster sizes. I would like to know what would be better a single 60 node cluster of 6 x 10 node clusters and why?

Hi!
I'm having problems with a VM inside Hyper-V 3.
occasionally not access second virtual disk attached SCSI.
in the event viewer inside guest:
Depud is disabled, only FSRM is installed with quota's configuration for users.
It's a bug? there are any hotfix to resolve this issue?
Thx
We have Windows 2012 Servers on 4 HP blades. We build network configuration:
1. build network team on 2 network cards on each server (for VM and OS management access)
2. network team have 1 default interface (without VLAN) and default settings (SwitchIndependent and TransportPorts)
3. we dedicate 1 network card for Heartbeat/Live Migration (without teaming)
4. we use network team from step 1 to create hyper-v virtual switch, this switch we also use for host management (with VLAN ID)
5. VM are connected to virtual switch from step 4 and have VLAN IDs in their adapter properties
6. VM which are several NLB clusters members have spoofing-enabled virtual adapters
When I perform Live Migration, VM move successfully, but NLB clusters members sometime generate error about IP adress 0.0.0.0 conflict after migration. After that only VM reboot or network connection disabling/enabling (in Windows) restore network connectivity. MAC spoofing setting ("enabled") is preserved during migration.
When we had Windows 2008 R2 cluster, we used HP teaming with multiple VLANs and created separate virtual network for each VLAN ID (except host management). Live Migration was processed without any error.
Is this network configuration issue? Must we change our network configuration (management network dedication, teaming mode changing and so on)? May be we must change network equipment (switches) settings (VLAN and so on)?
Hi
I am not sure if this issue has already been fixed
Hope this makes sense.... Has anyone see these issues.

Is it possible to run the Windows Server 2012 Essentials within a VM running on a Windows Server 2012 Standard installation with Hyper-V enabled?
I need to setup the Windows Server 2012 Essentials and it was suggested that maybe I should run it within a VM using Hyper-V for the purpose of running this along side another server product to reduce the hardware/power consumption in our small space. I am wondering if there are any issues that I should be aware of that might cause problems with all the features of the Windows Server 2012 Essentials remote access and VPN functionality when running this in a VM. Is it possible to have public IP assigned directly to the VM (with the host in the DMZ) as I intend to make the server accessible to remote users or does it have to be NATed?
Any advice you can provide will be greatly appreciated. Thank you in advance!
I am going to review the posts on how to clone a VM properly, but I want to check to see if I will have any issues with the way I did it.
We currently have a 3 host cluster, running on Server 2008 R2 Datacenter. We are also running System Center VMM. We recently created a new Application Farm, where the a single VM was loaded to a particular level, and then we cloned it - basically added it to the library - and created VM's from it.
My biggest concern - the VM's are all in their own separate folders under C:\Cluster Storage. But their VHD names are all the same - contain the name of the first server and the same number ID.
So - if the first server was called "Server 1) it's VHD was called "Server1.vhd. Server 2 was created and named as such -> but its VHD is called "Server1.vhd" and so on.
Am I going to have issues?
Hello all and thanks for your time and experitse.
My first question has to do with the NIC configuration on the Host and VMs. Here's what I've done so far: The host has two NICs. In virtual Network Manager, I dedicated one of the NICs soley for the Mangement (host) operating system. I then dedicated the second NIC for the VMs. I'll use the Host Nic to RDP and access it when I need to. I'm using the VM Nic (connected to the external network) soley for the VMs. The mac addresses have been assigned dynamically. I just want to make sure I have this setup in the recommended fashion. There will be two VMs running on this host.
My second question concerns the memory allocation. The host has 8gb of ram. I'm going to be running two vms. One of the vms will have 2 1/2 gbs of memory and one will have 2gbs. That should leave almost four gbs for the host. Is that an acceptable allocation of memory? Would it be possible to install a third vm in this type of configuration with only 8gbs installed on this host?
Additionally, the operating system I'm running on the host is 2008 enterprise r2. Is it still recommended to created a fixed disk or is the dymanic disk ok in terms of performance?
Your help and recommendations are greatly appreciated. Just want to get these nodes setup correctly and for max performance.
Hello!
I am troubleshooting the issue when the VMs are unresponsive via Hyper-V VM Connection console, but works via the RDP console. Updates seem to help and after them both types of connection work, but we need to determine which specific update helps it. What would be the way to determine which hotfix/update does the trick. The reason of such selectivity is simple. There are a lot of VMs with the fresh-built parent disk without any updates so we need a quick and small-size fix for them.
Environment:
Hyper-V Host: Windows Server 2012
Guests: Windows 2008 R2, Windows Server 2012, Windows 7 SP1, Windows 8
Thank you very much in advance!
