i want make hyper v server stand-alone with Microsoft Hyper-V Server 2008 R2
i have Processors intel i3 2120,RAM 4gb,hardisk 500gb and i want buy motherboard intel desktop board DZ77SL-50K/intel desktop board DH77KC

it can work??or i need intel gigabit ET Dual Port Server Adapter to??

or any one suggestion me what i need to make hyper v server stand-alone???

before i use motherboard gigabyte h61m-ds2 but that server can't be read any nic, so i think must use intel nic/product.

Inactive Hyper-V VM slow to respond to initial file request

Hello All,

 

I have a response issue with two VMs that have little to no activity on them and seem to go to sleep after 30 minutes of inactivity.  Once sleeping, the VMs are very slow to respond to the first file request and the Robocopy or Windows Explorer utilities will timeout with a "network path was not found" error.

 

After the initial file requests have failed, the VM wakes up and responds normally to subsequent file requests.  Has anyone else seem similar behavior and do you have any suggestions on how to resolve?  I can live with some initial latency but need to avoid the timeout errors.

 

The VM runs in a Hyper-V clustered configured as:

   2 node Hyper-V cluster consisting of:

   Windows Server 2008 R2 Datacenter

   2 Dell PowerEdge R710 servers, Dual 6 core CPUs, 64 GB RAM

   2 Broadcom BCM5709C NICs for LAN access

   2 Broadcom BCM5709C NICs for iSCSI access

   EqualLogic PS4100, Configured for RAID-10

 

The VM itself:

   Windows Server 2008 R2 Standard

   Dynamic memory, Startup RAM: 512 MB / Max RAM: 2048 MB

   2 virtual processors

   Dynamically expanding VHD

   Configured for failover in the cluster

 

The are 6 other VMs running on the same host but these are all small processes (< 1 GB memory each) and all the performance indicators look good (ie. network bandwidth; processor utilization; iSCSI traffic, latency and queue depth).

 

I would appreciate any thoughts that you might have on how to monitor and troubleshoot this issue.  Thank you.

Hello I have a windows 2003 server running on hyper-v2008r2.  Let's call it VM1.   This VM1 server is a domain member server and a critical machine.  Well we need to clone it.  I can't seem to find online what the results are of cloning a production machine.

So here is my method, with my questions.

1: shut down VM1

2: copy the VHD

3: with VM1 off, fire up the clone

4: run newsid to change name to VM2/reset sid

QUESTION: when i change the name, will it remove the old AD account for VM1?  This is my main question.  Will my VM1 still work? or will changing the name on the clone nuke the old VM1 computer account?

5: complete name change/new ip

6: fire up VM1

thanks!

I setup my host and 2 VMs (Win2008 R2) with the following credentials...

companyadmin

password

I come in today and the HOST of the two VMs is logged in as...

Administrator

I've never used Administrator and no passwords work (so I'm locked out of the host). I'm the only person that even knew the username/password so I'm really confused. 

I CAN remote into the VMs from a workstation. Is there any way, from the VMs, to access the Active Directory on the HOST?

Thanks!

One of the great features of Hyper-V Server 2012 RC is the ability to have VHDX files greater than 2 Tb in size.

 

Is there any way to install a VM to boot off a large (> 2 Tb) VHDX?  I created a 5 Tb VHDX, but when installing Windows it apparently formatted the VHDX as MBR.  I ended up with a logical C: drive (around 50 Gb), a 1.6 Tb (if I recall correctly) D: drive, and about 3 Tb of unused space.

 

What I'd like to end up with this VM/VHDX is a logical C: drive (around 50 Gb) and the remainder (just shy of 5 Tb) as a logical D: drive.  My intention would be to use the D: drive for everything other than the OS itself.

 

Is there any way to accomplish this?

 

I know that I can create two VHD/VHDX files - one which will end up as MBR for the boot drive and the second which will become GPT for my data drive.  But doing this would give me around 50 Gb of space on the logical C: drive that will effectively never be used (and thus lost space).  I know that's not much in the overall scheme of things, but "waste not want not."

 

My Intel motherboard supports UEFI and Hyper-V Server 2012 RC itself is installed on this GPT formatted drive (over 5 Tb in size).  But given the hardware is abstracted from the VM itself I haven't found any way to effectively perform a UEFI boot of the VM (which then should allow me to use the VHDX file as a GPT partition within the VM).

 

Does anyone know if this can be done and if so how?

I have a DC in a Running-Critical state.

Host: Server 2008 R2 DataCenter SP1

24GB RAM (8GB Free)

3TB (2TB free)

6 NIC's (Intel Gigabit ET2 Quad, Broadcom BCM5716C NetExtreme)

Dell Power Edge R510 Single Intel Xeon E5630, PERC S300

VM: Server 2008 R2 Enterprise SP1

1GB RAM

128GB VHD

Single VNIC

Dell Open Manage has no hardware errors.  Event Viewer has no error, warning of Event ID 50 (Time-Service).  All times are correct across all VM's and Host.

I am able to RDP into the VM, browse, ping, query, perform AD Lookups, authenticate... It's running.  Just not sure why it is in a critical state, what is causing it, or how to fix it. 

I can browse to the VM location on the physical disk, There are no Snapshots.  Heartbeat is OK.  This is a production environment, so restarting and shutting down is not an option during normal hours (7am-6pm CST).

Any help with this would be appreciated.

Hello there !

We have a a number of Windows 2008 R2 machines and we wish to provide an encryption mechanism for each Virtual machine.

It's a VMware environment and all the VM files go into NFS drives.

Do you think , Bitlocker will help ?

Is Bitlocker supported on Virtual machines ?

In my opinion , Bitlocker is to safeguard against any "physical" threat to a machine.

But I wanted a second opinion here.

Please help me.

Hi all,

I've a two node Windows 2008R2 SP1 cluster with Hyper-V. I've several virtual machine on the top of this cluster. If I configure an automatic start action for a virtual machine (for example I set to "auto start") and then I live migrate the VM to an other node, I loose the setting. It is resetted to "no action".

I've tryed to configure the setting via Hyper-V, via SCVMM, via FailOver Cluster but the setting is always not retained! Is it a bug?

Hi,

I need to create a laboratory (ALL VIRTUAL) of a two-node cluster to do some tests.

Currently configured:

* a machine windows 2008 R2 x64 that acts as a DC

*two machines with Windows 2008 R2 EE to create the cluster.

How do i virtualize a quorum?

Hi,

I have a environment like

1. We have 2 hosts and both are active nodes.

2. Created a CSV like C:/ClusterStorage/Volume1 in host1 i.e node1

3. Added a VM in node2 using the VHD available in the CSV.

4. Now trying to backup the VM from Node 2.

I'm using Hyper-V VSS Writer to backup the VM's. I'm able to take snapshot but unable to read the VHD file from the CSV. Getting the error code 1920(ERROR_CANT_ACCESS_FILE). I did some search and found the Cluster API's. then i tried the following stpes

1. Find the volume is CSV using the function ClusterIsPathOnSharedVolume

2. If volume is CSV i tried to get the volume mount point

ClusterGetVolumeNameForVolumeMountPoint(L"\\?\GLOBALROOT\Device\HarddiskVolume1\ClusterStorage\Volume1\", lpszVolumeName, MAX_PATH);
But still im getting the error code 5. (ACCESS_DENIED). Whether I'm doing everything correctly or not?. if not what is the correct way to do this?
Can anyone please tell me solution for this? it is urgent. Thnx in advance..
Regards,
ilavaa.

I hope someone can help me with this. Here is the scenario I am faced with.

I had VMs running on an external ESATA raid array (E:) off one of my test servers. Unfortunately it had a failure and had to move the VMs to a new external ESATA raid (G:).

I noticed that even after the VMs where exported from the old raid and then imported on the new raid, the VMs are still mapped to the old raid. I can't turn off the old raid due to this reliance. I have tried to remap all the VMs accordingly, but there is still something keeping the VMs mapped to the old configuration files. I cannot find anything that is pointing to the old raid. All VMs with this reliance go critical when the old raid is turned off. This is all done with Hyper-V manager.

I have Server 2008r2 Ent. and tried to install multiple technet versions of 2008 installed as VM's for demo of SCCM 2012. Is there a limit to how many can run in this license? I cannot seem to start more than three. I created 4. Maybe its a maximum based on the Technet PID?

My company wants to get started with virtual machines. We have a small network - only a handful of servers. I'd appreciate some feedback from some of you with experience. (If my questions are already answered on a Microsoft web site somewhere, feel free to point me to that information.)

1) I've been researching Hyper-V as well as VMware and Oracle VM. What are some opinions of the pros and cons of each?

2) We may want to start out small and not use shared storage to begin. What are some things are difficult or impossible without shared storage? Specifically, is a live migrate possible? If no, what about taking the VM down, copying the VHD to another host and bringing it up there?

3) WS2008 Std supports a maximum of 32 GB RAM. If the physical host has 64 GB RAM, 2 2008 Std VMs can run, each using 32 GB, right? What about the Hyper-V host? Would that OS need to be Enterprise?

4) What kind of overhead is on a Hyper-V-hosted VM compared to an identical physical machine?

5) How do you manage Windows updates? I am familiar with how updates are needed and the machine needs to restart maybe once a month. The Hyper-V host, being Windows, would be subject to the same restart requirements. Is your practice to migrate the VM to another host, install updates, restart and then migrate the VM back again?

6) I have discovered Virtual Machine Manager (VMM). What other tools are needed and/or useful?

Thanks in advance for your answers.

Hi all,

We are evaluating Hyper-V on Windows Server 2012, and I have bumped in to this problem:
I have a Exchange 2010SP2 DAG installed on 2 vms in our Hyper-V cluster (a DAG forms a failover cluster, but does not use any shared storage). As long as my vms are on the same host, all is good. However, if I live migrate or shutdown-->move-->start one of the guest nodes on another pysical host, it loses connectivity with the cluster. "regular" network is fine across hosts, and I can ping/browse one guest node from the other. I have tried looking for guidance for Exchange on Hyper-V clusters but have not been able to find anything.

According to the Exchange documentation this configuration is supported, so I guess I'm asking for any tips and pointers on where to troubleshoot this.

regards,

Trond

I want to expose my TV Tuner card directly to a VM, rather than use the network bridge if I can avoid it... since I'm waiting on Server 2012, the discussion should be relatable to that instead :)

Hi

I have inheritted a virtual exchange 2003 server, 2 of the virtual disks on the server have 7 or 8 snapsots that have been taken and deleted. The AVHD files and orginal VHD files are still on the virtual host.

As these files are so large, is there any way of merging them whilst the server is still live or must I shutdown to do the merge?
