Hi Everyone,

I have recently purchased a Dell PowerEdge T620 with the following specs:

Intel Xeon E-5 2630v2

16GB Ram

2x300GB Raid 1

4x600GB Raid 5

I setup the host OS on the Raid 1.  I then created 2 VM's, both with 64GB fixed VHDX's for the OS.  VM1 will be the DC so I won't do anything different with that (unless I need to).  VM2 will house our medical billing software, SQL and also be a Terminal Server for 5 users.

How should I setup the VHD's that will house the applications such as SQL, billing software etc? 

1. Should I create another fixed disk for the Applications (billing software and SQL)?  And leave the guest OS's on there own fixed disk?  If I should create a fixed disk for the applications, should I make it the for the rest of the space on the Raid 5 or just big enough for the applications that I need it for?  The SQL databases only take up around 50GB's.

2. Right now the 2 64GB fixed VHD's are on the Raid 5 in a folder named Virtual machines, should I move those 2 VHD's to the Raid 1 or leave them on the Raid 5?  Or should I split them up?

How would you go about setting up this environment?  Also, should I use pass through disks vs fixed disks?

Thank you in advance for the help, I really appreciate it.

When I'm running a Hyper-V VM (which I run most of the time) that is set to use 8GB of RAM, occasionally my mouse will experience "stuttering" or lag.  It can happen multiple times in a row, and sometimes is spaced out over hours.

Machine specifications:

Windows 8 Pro

i7-2500

16GB RAM

nVidia GeForce 470GTX

Hyper-V VM is on a secondary SATA drive that is only used for Hyper-V

Hyper-V VM is using 8GB fixed (another one is using 8GB min, 12GB max -- not running at the same time of course) with 2 vCPUs and two VHDX's, fixed.

os: windows 2008 R2 sp1

network: 2 subnet ( 10.1.1.0/24 ( 1st ISP) , 10.1.2.0/24(2nd ISP) )

2 physical switches (1st switch 10.1.1.0/24, 2nd switch 10.1.2.0/24)

Server has 2 physical nics. 1st nic connect to 1st switch, 2nd nic connect to 2nd switch)

I setup 2 physical nics for virtual network, one for 10.1.1.0/24, one for 10.1.2.0/24.

I can only put  gateway in one nic.

VM using 10.1.1.0(1st virtual network with external), it can go to internet ( using 1st ISP).

2nd VM using 10.1.2.0(2nd virtual network with external)  does not have internet access. 

How do setup 2nd vm to go internet using 10.1.2.0 network ?

Thanks

Hello,

I have set up two Hyper-V 2012 R2 servers and set up VM replication. However, when I started the "Enable Replication..." Wizard for a VM, the wizard never asks me what replication interval to use. I have attached a screenshot for reference.

Why would this behavior occur? Also, is there a way to set replication interval using PowerShell?

Any insight you could provide would be most helpful.
Thanks!

I am running Server 2012 R2 in Hyper-V Server role for my home lab. I am trying to create a gen 2 vm, with Server 2012 R2 iso loaded in the SCSI DVD device, but every time I try to start the vm it fails to start with the following error:

This is the current settings for the vm:

This error occurs with any iso file loaded into the SCSI DVD device, and the error occurs even if creating a new vm from scratch. I have seen several similar gen 2 vm boot issues posted, but none with the exact issue that I'm having. The iso files all work fine when creating a gen 1 vm.

Hello,

I will try to explain the situation:

Hardware overview:

Server1 2008
Role: Hyper-V Server and Back-up Server
Physical

Server2 SBS 2008
Role: AD, DNS, DHCP, Exchange,
Virtual

Server3 2008
Role: Remote Desktop Server
Virtual

The server is performing very bad since design.
Solutions from supplier:
- cache on raid controller
- seperate raid volume for virtual vm's

But unfortunately those solutions don't work.

I would like to setup a new server and move the virtual SBS server to a new server, but not virtual.

How would you guys approach this case?
Hope to hear some reactions.

Hi ,

V host running Windows Server 2008 R2 and the VM running Windows 2K3 or Windows 2008 R2 are losing the network very often. The network adapter value get set "Configuration Error" and machine lose all connectivity .

If I re-add the network connection to the VM then it work fine .

Also if I install client OS like Win7 , XP then the VM network work fine and never show the "Configuration Error" in network adapter.

Any ideas what may be causing this issue? Is Win2k3.Win2k8R2 need any specific hotfix to resolve the issue ?

Thanks,

Suresh

Hi Team

I have installed Microsoft Hyper-V Server 2008 R2 in a stand alone server. This server is not on a Domain, but it is in a workgroup environment. I have enabled all the options available in theConfigure Remote Management option in the Server Configurationmenu in Hyper-V Server 2008 R2.

After that I have installed the Remote Server Administration Tools under Windows 7 PC(on a Workgroup) from where I intend to mange the Hyper-V Server 2008 R2. After installing the RSAT, I have enabled the Hyper-V Tools from the Turn Windows Features on or off. Now I have an option calledHyper-V Manager under Start --> All Programs --> Administrative Tools.I launch this Hyper-V Manager and trying to connect to the server by specifying the Hyper-V Server 2008 R2's IP Address. After waiting for a while, I am encountered with the following message "An error occurred while attempting to connect to server "192.168.1.xxx". Check that the Virtual Machine Management service is running and that you are authorized to connect to the server. You do not have the required permission to complete this task"  and I am unable to connect to this Hyper-V Server 2008 R2.

When I am trying to connect to this server from Windows 7 PC where Hyper-V Manager is installed, I provide the administrator account of the Hyper-V Server 2008 R2 and the password.

Searching the net, I can't find any helpful assistance on this issue. Looking forward to hearing from some of the experts from MS Community. I also would be happy if you some one could post some procedure on creating the Virtual machine once I am successfully connected to the Hyper-V server as well.

Thanks in advance.

Regards

Jo

As I understand it the "Move Virtual Machine Storage" screen is supposed to enumerate the CSVs available to the cluster in the bottom left portion of the window.  It seems to be stuck on a "Loading..." status and never shows the CSVs.  Also, when I try the "Add Share" button and type in a share to use it doesn't do anything.  Thoughts?

I have a w2k8r2 server that runs hyper-v and hosts about 12 guests.  Lately the server justs reboots and doesn't place the guests back into the sate that they were.  There is nothing in the event log that says why nor any dump files.  It is a fairly new Dell R510 and i have run the diagnostics on it and sent them to Dell and nothing is reported in the hardware logs.  Does anybody know of other thigns i can look at?  i am spending the weekend moving the VMs off of the box and planning on a complete reinstall of the OS but to me it sounds more like a hardware issue.  Thanks

Hi,

My configuration :

12 physical disks of 1TB each

RAID 1 : OS ( 2 disks)

RAID 5 : for Data ( 10 disks)

I installed OS on the RAID 1 disk .so far so good :-)

After connecting to the hyper-v server from hyper-v manager on a windows 8 client to create virtual machines,i am able to create virtual machines but able to see only the C drive with 931GB space. 

How to use the other unallocated space for creating virtual machines on other drives ..i mean RAID 5 disks.

Could you please suggest me on how to use this  ? 

Thank you.

Dear Community,

as you probably know the new R2-Version was advertised with the ability of PxE-booting with the synthetic instead of the legacy-nic which works with poor 100 mbit/s.

Here´s the problem:

When I create a new virtual machine with Gen2 without the option "Secure Boot" and PxE-boot it, I get the following error:

Boot failed. EFI Network.
Boot failed. EFI SCSI Device.
No Operating System was Loaded. Press a key to retry the boot sequence

When I create another new virtual machine with Gen2 but with the option "Secure Boot" and PxE-boot it, I get this error:

Station IP address is x.x.x.x
Server IP address is x.x.x.x
NBP filename is pxelinux.0
NBP filesize is 15888 Bytes
Downloading NBP file...
Successfully downloaded NBP file.
Boot Failed. EFI Network. Failed Secure Boot Verification.
Boot Failed. EFI SCSI Device
No Operating System was Loaded. Press a key to retry the boot sequence

When taking a look at the log of the TFTP-Server (TFTPD32) I get the same information regardless which way I do it. The only interesting thing it says is:

"Peer returns ERROR <User aborted the transfer> ->aborting transfer"

I have also tried to use another tool called Serva as TFTP/PXE-Server -> The error still occurs.

Before anybody wants me to try to do it as Gen1 -> I know that this works, but I want to get it running under Gen2 since the synthetic one works (should work) much faster than the legacy-one.

Really looking forward to get some useful information here.

Thanks in advance !

Hi,

I have an instance of Hyper-V 2008 R2 hypervisor installed on an HP DL360 G7.  I have a Dell Equallogic with a LUN allocated with IQN and the correct IP address configured to be allowed to connect.

I have configured a virtual switch connecting the Hypervisor to the SAN and I can ping it.  How do I provision a VM in the storage through Hypervisor management console?  All the server sees is local or network storage but not the SAN.

Any advice, thanks Matt.

I upgraded my setup from windows 2008 R2 DataCenter to Windows 2012 R2,

But when i try Mount-VHD cmdlet,it is giving me an error not recognized cmdlet.
It worked on my other setup where fresh install of win 2012 r2 is done..

This is the command i use in win 2008 R@
$VHDService = get-wmiobject -class "Msvm_ImageManagementService" -namespace "root\virtualization\v2" -computername "."

$VHDService.Mount($Paath)

Now the above command is also not working!

HyperV 2008 R2 Cluster with 2 nodes.

Host to Host traffic is as expected at 75-100MB/s. Inter VM traffic even when on the same host was at 5-6MB/s.

I installed latest firmware/drivers for all host nics. Disabled TCP Connection Offload, large send offload, RSS and Chimney globally using netsh,  and  Virtual Machine Queues. The speed improved to 20MB/s but this is still drastically slow. 

We are also experiencing this on other 08 R2 cluster's.

Has anyone experienced this and found a solid solution? I have followed a lot of the other threads but no one seems to have a definitive answer/solution for this?

Hi guys,

we have a Server 2012 with a NVIDIA Quadro 6000 gfx card. This Server runs Hyper-V and it hosts Windows 7 SP1 Enterprise VMs with installed RDP 8.0 update.

We installed the gfx card driver and added remotefx-vgpu to our virtual machines. 

When we try to connect to a VM via RDP-Client, we just see a black screen for about 20 Seconds and then the session close.

Without RemoteFX-3D Card enable everything works fine.

Can anyone help us?
