What would my solution be with Hyper-V and Terminal Server?

Wed, 25 Nov 2009 08:39:24 Z

Hi guys.

We would like to create a remote office with 10 Thin Client users on Server 2008 standard and a Terminal Server. We have the same solution running in another of these branches but on Server 2003 , but on 2 physical servers. PDC on Serve 2003 SBS, and the Terminal Server on Server 2003 Standard.

With 2008 and Hyper-V we would like to know if we could run one physical server running Windows Server 2008 standard, and a Hyper-V virtual Terminal Server, both on the same box.

Is this possible and viable?

Could you guys advise on the best solution?

Thx in advance

Enabling the Hyper-V role on Windows 2008 R2 causes the NVIDIA driver (and ultimately the system) to crash

Tue, 24 Nov 2009 05:45:40 Z

Hi!

I recently bought a machine with i5 processor, 4 GB RAM, NVIDIA 8400 GS card. I installed Windows 2008 R2 x64 enterprise edition on it and the drivers for the NVIDIA card. Everything worked fine. But then I added the Hyper-V role in it. And on the next reboot, the NVIDIA driver caused a bugcheck.

To make sure that it was an interop issue, I tried reinstalling the OS a couple of times and then the driver. As long as the hyper-v role was not added, everthing worked cool. I have tried this with the drivers that came along in the CD and then I downloaded the latest drivers from the site for Windows 7/ Windows 2008 R2 x64.

Is this a known problem?

Thanks,

Ayush Gupta

Hyper-V hosts with Low max IOPS

Mon, 23 Nov 2009 10:35:28 Z

Hello,

When I use migration in SCVMM, all of my my hyper-v hosts have a no-star rating because the projected disk I/O utilisation exceeds the maximum of 1611, this maximum is the same on all of the hosts and seems very low. I'm not having any performance issues with my servers. Any idea why this maximum is so low?

Many thanks,
Jonathon

Pass-through Disk in 3 node cluster

Wed, 18 Nov 2009 03:57:03 Z

It is posible to use pass-through disk in a cluster with 3 nodes??
I have read this blog http://blogs.technet.com/askcore/archive/2009/02/20/adding-a-pass-through-disk-to-a-highly-available-virtual-machine.aspx however, I've like to know whether this is a valid configuration. We are using Hyper-V R2.

Hyper V R2 cluster - Live motion and PT disks

Fri, 20 Nov 2009 04:01:58 Z

Hi ,
The cluster is made of 2 HP DL380 hosts with a MSA2324FC storage .
All the setup passed the cluster validation tool .
I've created 8 VMs all with virtual disks on some CSV LUns .
All went fine and Live motion worked as well.

Then I tried to add a PT disk to a VM.
I presented the LUN to the two hosts.
On one of them I enabled it and initialized , then I disabled it .
Went in the Hyper-v MMC and added the LUN to the VM.
In the guest OS I formatted it .

Then I tried to live migrate the VM and it fails
cluster validation tool fails as well and VMM2008 reports the VM as "unsupported cluster configuration"

does anyone know if that's a supported scenario , I've had different answer on this, and what might be the problem if were supported

Thanks

Microsoft Virtual BIOS failed to power on

Tue, 24 Nov 2009 11:07:02 Z

I spent so much time looking for a solution to this problem and can't find any. Here's the error:

By hypernova
I'm positive that Hypervisor is running. My processor is i7-860 and motherboard is Gigabyte P55M-UD2. I'm a student (using R2 from Dreamspark) so I'm not very fimilar with this topic. I would appriciate any help. Thank you.

CPU in VM will at random times max out for 20-30min then go back to normal

Thu, 24 Sep 2009 17:37:47 Z

I have a VM that runs good most of the time, but at other seemingly random times the CPU will suddenly spike to 100% for about 20-30min before returning to normal.

The task manager in the VM does not show anything unusual, so I'm thinking the VM is suddenly getting less resources. only problem is that this VM is the only VM on the entire box. The node itself of course shows little resource usage. I also notice in performance manager C3 idle time in performance monitor is near 80% when this is occuring, yet the VM is maxed out. VMM shows the VM is using ~25% when the VM itself is reporting 100%. The thing is this VM is not using a lot of resources, I am sure of that...

any ideas???

thank you

cluster printers running on hyper-v onm win 2k8

Wed, 25 Nov 2009 00:28:19 Z

I am running hyper v and built two win 2008 servers to test clustering print manager. I dont know how or where to share the storage? The pc running hyperv is in workgoup mode and the two 2008 servers I am trying to cluster are in a domain I created. They are both joined to the cluster but I need to share the storage, this is where I am confused?

File Cluster - traditional style or virtual machine

Tue, 24 Nov 2009 23:29:26 Z

Greetings

we are running W2008-R2 Hyper-V on a HP C3000 on four blades setup as two separate clusters (HP2012I and MSA2000 over ISCSI)

we have several virtual machines in HA mode running fine (member servers, specialized roles) (can live migrate fine etc)

we now want to setup our main File - Print server within the cluster

Does everyone recommend setting in up as a plain file cluster (application) - or to do it as a VM?
(we could only add data to a test File VM by creating additional virual harddisk / vhd file bought would rather address the file data outside this)
(we dont need clustered shared volume storage for this new file cluster as we can dedicate this lun to this one task)

(we would rather not have our 300+ GB of file data sitting in a large vhd file)

thanks - any advice welcome

Server Model Recommendations?

Tue, 24 Nov 2009 22:03:26 Z

I am curious as to why I have been unable to find any online resources discussing the "best" hardware to use as a Hyper-V/VM host machine. In the SQL Server world, there seems to be a general concensus that for heavy duty enterprise db's, go with the HP ML370. I could find no such obvious recommendation for a Hyper-V server. Perhaps there are too many implementation possibilities...

If I want to avoid SAN and DAS for now, and I am lookign for the best machine to reliably host as many 2008 R2 Hyper-V VM's as possible, what are some of my options? Spindles and RAM and cores, oh my.

Is the ML370 worth considering? Is there a Dell option?

ISA Delaying packet transmission

Tue, 24 Nov 2009 22:04:17 Z

We are running ISA 2006 with all the required updates and patches. Recently we introduces a Point of Sale device behind the FW that is running into transmission issues (timeouts). All other devices such as workstations are not having any issue at all.

The problem took some time to isolate to the ISA Firewall. The problem is ISA is for some reason delaying the delivery of packets of these POS system to the HOST system (on the internet).

Our tracing has confirmed that packets are arriving in at the FW (on the inside) and tracing (on the outside) has confirmed that these packets are delayed (sometimes a few seconds) before being sent out in a burst.

The result is that the POS system thinks there has been a problem and retries the operation only to have the ISA server repeat holding packet delivery. It’s as if ISA is trying to be efficient and is gathering several packets for a given destination and sending all together.

Does anyone have some insight?

Hyper-V R2 Cluster and iSCSI RAID

Tue, 24 Nov 2009 21:44:13 Z

Hello, I have some questions about Hyper-V R2 Clustering and iSCSI. I am new to SAN and iSCSI, we have always used internal storage as our data storage needs have been light.

We currently run three Hyper-V stand alone servers with internal storage. As our environment has grown and we have about 15 VM's single point of failure has become a worry to us. We have decided to implement Hyper-V clustering with 3 Dell PowerEdge R610 and MD3000i iSCSI Array and two Dell PowerConnect Switches.

The servers will have 24 GB Memory, 2 Quad Core CPU's and 2 Quad NIC's 1 Quad will be TOE iSCSI enabled the other for 4 for 1 managment NIC and 3 for VM's. 2 servers to run the VM's and one as a Hot Spare. We can add additional servers to cluster if we need to scale up and add more VM's.

Questions:

1. What is the recommended RAID config for the iSCSI array for the cluster? I have seen RAID 10 recommended.
2. Is there a performance hit with iSCSI compared to internal storage. I would imagine some but how much?
3. Most of the VM's have low disk IO requirments but there will be a couple servers with SQL 2005 on Windows Server 2003 installed. Is it better to assign the SQL VM's all VHD's for all drives or make the System partition a VHD (which it has to be) and then make the transaciton log and DB's drives direct access to the iSCSI array. If we do the latter will the SQL Server VM's still be clustered fault tolerant?
4. For the iSCSI array (I know, this is the Hyper-V forum but I think relevant) it will have quad NIC's two to each switch and each Hyper-V host will have two NICs into each switch can and should the NIC's be teamed or Link Aggregated. Will this theoratically double bandwidth or just provide fault tolerance?

Thanks in advance and also if you can point me to any Hyper-V R2 cluster iSCSI SAN best practices docs or whitepapers I would appreciate it.

Thanks.

911 - Hyper-V Server 2008 R2 installer hangs

Tue, 24 Nov 2009 19:58:47 Z

I have a machine with Intel Q6600 processor. BIOS settings are done (with cold boot). I have a fresh SATA HDD (148 GB) - completely unformatted and raw

downloaded the lastest Hyper-V Server 2008 R2

Installation starts, shows Language selection. I select "English", no change on next screen (lang preferences) --> Install Now

The installation start and then after 10 seconds or so, it hangs. Keyboard and mouse are frozen. I have no clue what is happening (waited for 30 min just in case something is happening) but no luck. After 1 hour I forced reboot.

Can someone help?

Import Fails "The system cannot find the path specified" (0x80070003)

Tue, 24 Nov 2009 21:10:02 Z

I did see a post related to this that did not fix my problem by editing the "EXP file value "ScopeOfReference".

Environment:
Host A
OS- "Win Server Standard SP1" 64 bit (2008R2)
Domain Admin Account Logon same for both Hosts
Hyper V Server role enabled
Hyper V Manager utilized through RDP Session on this Host.
SCVMM 2008 Trial ver.2.0.3444.0 (Stopping use due to the high number of failed jobs and support complexity)

Host B
OS- Hyper V Server R2 (Core)
Domain Admin Account Logon same for both Hosts
Hyper V Enabled
Drive D: dedicated to VM's
Drive V: Storage

Issue:
I have some VM's on Host B that I want to move back over to Host A.

Action:
I use Hyper V Manager to select the VM on Host B and "Export" it to the local storage drive partition. From the same Hyper V Manager, I now select the Host A server and select Import Virtual Machine and browse to the folder with the exported VM. I select the root folder name "My Virtual Machine Name" that contains [Snapshots, Virtual Hard Disks, Virtual Machines].

At thispoint I get "Import Failed".
Unable to search imort files under location "V:\My VMName\". Error: The system cannot find the path specified. (0x80070003)

I can explore, open and edit these files from Host A Windows Explorer browsing to Host B shared V:\ drive.

I just decided to trash SCVMM due to the complexity of operation work around (outside the box) and resources involved in finding solutions so I really need to get Hyper V Manager working correctly ASAP.

P.S. I have already rebooted both Host Servers and I did remove server Roles "Application Server" and "Web Server" from Host A since I had assumed it was causing me problems with SCVMM prior.

Anyone think they know the exact cause of my current issue?

Windows 2003 Sp2 SQL2000 SP4 - Poor Performance on Hyper-V R2

Fri, 13 Nov 2009 22:53:14 Z

Hi
its a simple issue and i have removed all the old legacy hardware software and management packs etc.. so it just has sql 2000, siebel 7.3 and symantec endpoint in unmanaged mode with just the antivirus components
the machine only had a single quad core and 4 gb of ram and i have assigned the same resources to it in the virtual environment.
but yet things do not perform even close to what it was, i do understand there will be a performance impact but this is fairly major
the host is basically the same machine the physical machine was on only it now runs hyper-v.

accessing the system is generally slow and everything seems to trundle along...
any suggestions ? on how to troubleshoot or fixes! :)

thanks in advance

Microsoft Hyper-V VSS Writer Issues

Tue, 05 Aug 2008 15:07:07 Z

I'm running Server 2008 with Hyper-V.

I have a simple script that uses diskshadow to utilize VSS to copy my virtual machines to a NAS device:

echo Delete Shadows Volume C:\                             > Script.dsh

echo COPY "X:\Virtual Machines\MYVIRTUALSERVER\MYVIRTUALSERVER.vhd"  "\\192.168.1.14\backups\MYSERVER\MONDAY\Volume{148e48a7-543a-11dd-b6ed-806e6f6e6963}\Virtual Machines\MYVIRTUALSERVER\MYVIRTUALSERVER.vhd"  >> CopyVM.Cmd  

DiskShadow /s Script.dsh  

Exit

When i tested this on the server, it worked fine. It created the shadow, exposed it, copied it to my NAS and finished.

I added the job to scheduled tasks and set it to run in the evening. For some reason, it failed with the following errors in my event log:

I did some googling, but nothing specific comes up for any of these errors on Server 2008 or Hyper-v.

I did go into diskshadow and noticed that my Writer for Hyper-V did indeed dissapear (as indicated by the error message). I restarted Hyper-V Virtual Machine management and was able to manually fire off the backup with no issue.

Anyone have any thoughts on what happened during my backups? I'm trying to stabilize the process until another backup solution is available that can do this process for me.

Thanks!

Making VM Highly Available

Mon, 23 Nov 2009 15:58:43 Z

(Using Microsoft Hyper-V 2008 R2)

I have a VM created locally on one of my nodes. This was done before i created a cluster hosting this and another node.
I would now like to move this VM to the cluster to benefit from HA.
How do i go about moving the VM form its default locally installed location to the a CSV location on my cluster?

kind regards

"Virtual Crossover" connecting 2 virtual switches

Sat, 21 Nov 2009 15:45:33 Z

I have a Hyper-v host with 2 NICs that are connected to 2 physical switches. Both of these are on the same network/vlan. This is to provide redundancy for an iSCSI network. The Storage arrays recommend this setup.

The arrays have 2 controllers, and each controller has 2 NICs. This way if either physical switch or pNIC goes down, the machine can still contact both controllers.

I have several guests on this host that also connect to the array. I could attach each guest to the 2 virtual switches, but I was wondering if it is possible to bridge those switches on the server. This way, each host would only connect to one virtual switch, and if one of the physical switches were to go down, the hosts would still have access to both controllers on the array through the "virtual crossover" in Hyper-V. This would also provide redundacy for the pNICs as well, because if one of them goes down, the Guests could use the other pNIC.

This seems like this should be an easy thing to do, but I can't find any documentation on it.

Any help would be appreciated.

Pass Through Disks used in VM with Mount Points supported?

Tue, 24 Nov 2009 14:24:41 Z

Hello,

we discussed another particular configuration this week and now I was wondering if this is supported by Microsoft.

But first a quick hardware overview:

three-node-failover-cluster running on blade servers
FC attached SAN volumes
clustered HA-VM with 4 SAN-volumes configured as Pass-Thorugh-Disks

And here is the crucial point:

Is it, inside of the VM, supported to mount 3 of the disks into the fourth ?
(First LUN configured with drive letter F:, second-to-fourth LUN mounted into F:\first, F:\second, and so on)?

Hypothetically speaking, it ought to survive, but is it supported?

As I'm not very familiar with mount points, what would happen if one of the mounted volumes fails already in SAN?
I guess the disk just disappears in the VM and the folder remains empty?
And if the "root" volume fails, the other disks remain unmounted in disk managment of the VM, don't they?

Thanks for your help,
regards from Stuttgart,
Daniel Wittmann

Script or Tool to Shutdown all XP/Vista/Win7 machines that do not have someone logged into them?

Tue, 17 Nov 2009 21:55:57 Z

unable to join server core to domain

Mon, 23 Nov 2009 21:54:21 Z

I am unable to join my server core to the domain. Below is the configuration and details.

One DC (full w2k3 installation) setup as DC\DNS\DHCP. One 2008 server core (server1) with no additional roles. They are both VMs on HyperV. Server1 obtained IP settings from the DC. When trying to join server1 to the domain, it always complained that the network path was not found. I got the same error when trying to map a network drive from server1 on the DC. The net use command got the same error even if I used IP instead, e.g. net use m: \\192.168.0.1\c$. Firewall were off on both machines.

server1 can ping the IP of the DC, the domain name. server1 can nslookup lookup the just the CN as well as the FQDN name. I tried assigning the same VLAN ID for both network adapter for each VMs and it didn't help.

Anyone has any insight on this?

Thanks

MS-DOS 6.22 under Hyper-V

Mon, 23 Nov 2009 03:58:33 Z

My question is really 2-part. I have a temporary need for an MS-DOS VM on my Server 2008 (R1) x64 test machine, so I downloaded MS-DOS 6.22 from the TechNet subscription area and created 3 VFD files for each of the install floppies. I then created a new VM and proceeded to install DOS 6.22, only the message I got was...

"Setup cannot install MS-DOS 6.22 because there is no operating system on this computer. This product is the MS-DOS 6.22 Upgrade..."

Question 1) Why in the world would the TechNet version of MS-DOS be an UPGRADE version??? That makes absolutely no sense at all. Is a "non-upgrade" DOS 6.22 installer available?

Question 2) I read that Hyper-V doesn't support MS-DOS. Is this just because there are no integration services for it? I really don't need them for this test.

Off state in Hyper-V manager after node failover

Mon, 23 Nov 2009 16:26:22 Z

I have a four node hyper-v rtm cluster. I had a situation come up and some vms failed to other nodes in the cluster. After a refresh of the cluster in SCVMM R2, everything looks correct and all VMs are running. However, when I open Hyper-V manager and connect to all four nodes, I see some guests in an OFF state on the node they were previously running on. They did not disappear but are still showing on the old node in an OFF state. Has anyone else had this issue?

Thanks,

Chris

SCVMM 2008

Fri, 20 Nov 2009 14:38:41 Z

WE had our SCVVMM 2008 Working fine with our 3 node cluster of Windows Server 2008 Hyper-V Machines.

But now SCVMM is having difficulties communicating with the 3 node cluster.

IF we try to reinstall the agent we get the following message.

Product: Microsoft System Center Virtual Machine Manager Agent (x64) -- Failed to configure the WS-Management service. In the Local Group Policy Editor (gpedit.msc), navigate to Computer Configuration\Administrative Templates\Windows Components\Windows Remote Management (WinRM), and then ensure that there are no policy settings configured for WinRM Client or WinRM Service.

Anyone have any ideas? Thanks

Hyper-V AVHD File Access

Mon, 23 Nov 2009 11:48:16 Z

How to open an AVHD to access its contents? I want to extract a file from it.

The AVHD I want to access is the most recent in a tree of snapshots for a VM. I have deleted some of the snapshots in the tree, so the differencing chain is broken. The VM will start, but its state reflects the original VHD, and I can't merge this AVHD back into the original VHD.

I tried using the Edit Disk Wizard to reconnect this AVHD to its parent, but got an error that the Wizard was passed an invalid parameter.

Is there any 3rd party utility out there that can access a avhd regardless of the differencing chain? Dont care how much it costs , badly need it.

DiskShadow or API for single VHD?

Tue, 12 Aug 2008 23:54:24 Z

Hi,

Is there a way of using DiskShadow to backup just a single online vhd?
I haven't had any luck yet.

I have also looked at the VSS API, but before I go and implement something can anyone confirm that the API will provide some sort of option (if so what) to narrow down the backup to a file of choice?

I need something in the meantime before DPM SP1 comes out.

Thanks,

Martin

Hyper-V Server: "Hypervisor not running"

Wed, 26 Nov 2008 12:23:29 Z

Hello,
I'm currently testing (or trying to test) the stand-alone Hyper-V Server for my company.
After installing the Hyper-V Server and Drivers for Network, I was all set to go.
However, when I try to start a newly created Virtual Computer I get an error message telling me that the Hypervisor is not running (can't give you the exact wording because I'm using the german version, sorry).

I checked to see if the CPU supported everything necessary, which yielded the following results:
- it is a 64bit CPU (Intel Core2Duo E7300, 2x2.66 GHz)
- it does have Data Execution Protection (DEP), implemented as the Intel XD bit
- it does have Intel VT (capability for virtualization)
(however: Everest Home (a hardware analyzation tool) says that the CPU supports "Virtual Mode Extension", but not "Virtual Machine Extensions (Vanderpool)" or "Secure Virtual Machine Extensions (Pacifica)". Maybe this is the Problem?)

I activated these features in the machine's BIOS, and even pulled the plug on the machine (after properly shutting it down), as the Hyper-V manual says.

I'm guessing that the problem may be that the CPU supports virtualization, though the mainboard doesn't (or something along those lines). Maybe it is the processor, I'm not very knowledgeable about Hardware.

Can anybody help?

Thanks,
-Patrick

EDIT: Sorry, forgot to mention the mainboard type. The computer is a Dell Optiplex 760, I'm having some trouble finding out a model name for the mainboard, everest can't seem to recognize it. -p.

duplicate virtual network for non-exported VM

Thu, 12 Nov 2009 21:42:18 Z

I have a set of VMs and I have the VHDs and the xml file. I want tp preserve the IP settings on the VMs so I need to duplicate the virtual network for the VMs but I have no idea what virtual network name was used. I can get the MAC address from the xml file and I set static MAC address for each but when the VMs booted up they still detected a new network adapter and I lose my IP settings.
Anyone know of a way to get around this?

hyper-v r2 hot add/remove virtual storage how-to

Wed, 11 Nov 2009 05:23:48 Z

Three-Node Cluster Failover

Sun, 22 Nov 2009 15:00:11 Z

In a two-node cluster, when one is down, VMs will be failed over to another node.

What will happen in the case of three-node cluster, will they be equally distributed among the remaining two?

Mystery AVHD file and no snapshots lists in Hyper-v

Sun, 13 Sep 2009 19:46:24 Z

Need some serious help here.

I was the victim of the runaway shapshot eating all the availble disk space last year - that was a fun 30 hours to fix. I still hold the record of having a 400GB snapshot. Snapshot are evil in production - never to be used again.

Anyway...

I have one virtualized exchange server and in Hyper-V mangare, there is no snapshots listed (this is good, since it is an Exchange server and it is in production).

But, we are running out of diskpace again. I check the drive and there is a 151GB snapshot (which is active and being used by the Exchange server). A AVHD file - your basic snapshot differential file.

So, it looks like this blight of snapshots is not completely gone. How do I get rid of this snapshot?

I would like some suggestions before I start working on a production system.

What is the normal processor consumption on an Hyper-V Server? I mean the average rate of consumption? which is off course good enough for a failover? thanks.

[RC0] "Your Credentials did not work" Windows Security Popup

Fri, 28 Sep 2007 14:23:08 Z

I've configured the Server Virtualization Role and have been able to configure a new virtual machine without any problems. However, whenever I attempt to connect to virtual I receive the following Windows Security Popup: "Your Credentials did not work. Your system administrator does not allow the use of default credentials to log on to the remote computer <computer name> because its identity is not fully verified. Please enter new credentials." Whenever I attempt different account, also with admin privledges, I get a similar popup that states "The credentials that were used to connect to <computername> did not work. Please enter new credentials." Please help.
