2012 R2 Hyper-V HOST with virtualized 2008 R2 SP1 RDSH - Remote FX Capable?

This article goes over RemoteFX and RDSH for 2008 R2 SP1, but nothing is discussed in regards to 2012 R2 Hyper-V HOSTs for the virtualized RDSH server.
http://blogs.msdn.com/b/rds/archive/2011/03/25/q-amp-a-microsoft-remotefx-and-remote-desktop-session-host-servers.aspx
My goal is to use a 2012 R2 Hyper-V HOST server to provide RemoteFX vGPU performance to a 2008 R2 SP1 RDSH server. Is this possible? If not, are there any solutions that can provide graphics performance benefits to an RDSH server? If so, are there limitations?
What are the benefits?

Hi,
A Server 2008 R2 VM does not support vGPU (neither does 2012/2012 R2). One possibility if the apps you want to improve are DirectX-based is to run RDSH on a physical server, with a GPU installed,
and enable the Use hardware default graphics adapter for all Remote Desktop Services sessions group policy setting.
Please thoroughly test with the intended applications, GPU, and expected concurrent number of sessions to see if this configuration benefits you. It only potentially benefits DirectX applications, and only applies to full desktop connections,
not RemoteApps.
Additionally you may want to test Windows Server Technical Preview/Windows Technical Preview since it has enhanced vGPU capabilities for the VMs. vGPU is supported for a single-user Windows Server RDSH VM. Please see the document below (and
its comments) for more information:

Server 2012 R2 Hyper-V Host Loses Network Connectivity

Here's the scenario...
We have two 2012 R2 Hyper-V hosts (VM1 and VM2) in a cluster that have 8 virtual machines that live on them. The servers are each utilizing three network connections that are teamed (Switch Independent, Address Hash). They all go to the same switch.
Three nights ago at approximately 11:30 PM VM2 lost network connectivity. The server was up it was just inaccessible from the network. I could not ping in or out from it, no internet connection, yet the network connection icon did not show that it was
disconnected.
Two nights ago we had no issues.
Last night, same thing happened at 11:30 PM. VM2 loses it network connection.
The only thing that seems to fix the issue is a reboot. Once the server comes back up everything is back to normal.
Anyone have any idea what is happening here? I do not see anything that sticks out in the logs that could point me in the right direction....

Hi Sir,
Based on my experience , first you may need to keep the physical NIC driver up-to-date .
Also please check if there is "VMQ"/"virtual machine queue" property in advanced properties of physical NICs:
If yes please disable it for each team member then check the result .

Windows 2008 r2 guests blue screen on Windows 2012 R2 Hyper-V Cluster with e5 2670-v2 processors

Hello all,
We have a new hyper-v infrastructure deployed in two brand new Dell R720 Servers with 384GB of Memory and dual Intel e5 2670-v2 processors. This infrastructure is replacing an existing hyper-v 2008 R2 and all the guests are being migrated to this new cluster.
The issue we are seeing is our 2008 r2 guests blue screening ocasionally with 0x0000001a,0x0000004e or 0x00000050 bugchecks.
All this guests are configured with dynamic memory and with the integration components up to date. These same guests were running with no problems in the hyper-v 2008r2 cluster.
When searching i found this article from vmware that pretty much describes what we are facing:
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2073791
Are you aware of the same problem with this kindd of hardware on windows 2012 r2 hyper-v?
Thanks!
Nuno Carvalho

Meanwhile i found this May 2014 update on the intel specification of the CPU we are using:
CA135 Incorrect Page Translation when EPT is enabled
Problem:
If EPT (Extended Page Tables) is enabled, then a complex sequence of internal processor events may result in unexpected page faults or use of incorrect page translations.
Implication:
Due to this erratum a guest may crash or experience unpredictable system behavior.
Workaround:
It is possible for the BIOS to contain a workaround for this erratum.
Status:
For the affected steppings, see the
Summary Tables of Changes.
This affects VMware as of the today update of the article i referenced in the first post, what about hyper-v?

Hyper V hosts with Cluster Shared Volume do not provide Shared VHDX ability

Hi there, i've configured a pair of Hyper V hosts (UCS B230 M2) with SAN-Boot and access to a Shared Fiber Channel LUN.
No matter what I try, when I add a SCSI Adapter and one VHDX virtual disk to a VM, the option for "Advanced" never shows up therefore I can not share the VHDX file between another VM, which prevents any VM based clustering from working (IE: Clustered
SQL server)
Here are the settings I have configured:
The LUN has been formatted with NTFS
The Hyper V hosts have been configured as a Windows Cluster with an IP address and the Fiber Channel LUN configured as a Cluster Shared Volume
I follows the guides below
Create a CSV
https://technet.microsoft.com/en-us/library/dn265980.aspx
Create a shared VHDX
https://technet.microsoft.com/en-us/library/dn282283.aspx
Further details:
Two HyperV server core hosts built
Both joined to AD
Both joined to a Windows failover cluster
One 2TB Fibre Channel LUN presented from an EMC VNX array to both hosts
LUN formatted as NTFS
LUN created as a Cluster Shared Volume
Cluster Shared Volume present on both HyperV hosts
VM created within the Cluster Shared Volume
VM Booted up and Windows 2012 has been installed
VM gracefully shut down
Through the HyperV Manager, going in to VM settings,create a SCSI adapter, create a new VHDX file inside the CSV, the “Advanced” option for the VHDX is not present, therefore the option to make the VHDX file shared is not available
I have followed all steps in the Microsft Technet pages to create a CSV and a VM with Shared VHDX
I’ve cleared all settings and restarted multiple times, but this option is not present

Hi Sir,
>>No matter what I try, when I add a SCSI Adapter and one VHDX virtual disk to a VM, the option for "Advanced" never shows up therefore I can not share the VHDX file between another VM
>>Yes we are using Hyper-V Server 2012 R2
As we know Hyper-v server 2012R2 is a free version without GUI , I'm afraid you are not using Win 8.1 or other windows server 2012R2 to manage that free version hyper-v server .
Shared vhdx is a new feature came with 2012R2 , if use previous windows to manage 2012R2 you will not see "advanced" option (The blue circle belongs 2012 , the red circle belongs to 2012R2 ):

SBS 2011 VM and Server 2012 R2 Hyper-V host. After rebuilding the host image, no email is received, EMC states "You don't have sufficient permissions to view this data" when looking at organization config. Server config not shown on EMC.

Hyper-V Host Server 2012 R2 x64 drive c:
All VMs, including SBS 2011 Standard x64 are on drive d:
I replaced my motherboard and defined a Marvell RAID 1 Mirror for my boot drive C:. My drive D: containing all of my Hyper V machines remained untouched since the new MB had Intel Matrix Controller with RAID 5, as did the old MB.
Since the C: drives are a few bytes smaller after configured as a RAID 1, I was unable to restore drive C from the image copy, so I rebuilt a new Hyper-V Host identical as possible using Server 2012 R2 x64. I had to redefine the Hyper-V machines on
the host, and the 1st time I brought it all (host and VMs) I had to reconfigure the NICs due to new MAC addresses, and verifying SBS 2011 DNS and DHCP for all physical and Hyper-V machines. Otherwise my Hyper-V SBS 2011 x(64) wasn't touched.
Now the SBS Exchange 2010 is not receiving mail. In the Exchange Management Console clicking on the Organization config gives me a highlighted error "You don't have sufficient permissions to view this data". The Server
Config is no longer on the EMC. The Recipient Config looks fine.
Outlook 2013 x64 connects to the Exchange Server, but no new mail appeared. There were just a few older messages that came in since the last time I opened Outlook. My public DNS on GoDaddy was not changed. I did not change sending mail
through my ISP Sonic.net. The SBS internal DNS doesn't have an MX record, but I'm not sure it ever did since my GoDaddy public DNS has an MX record.
I tried restoring to an earlier Image Copy, but that made no difference. I'm using the Windows Backup from SBS 2011 for my daily image copy backups.

Hi Michael,
à
After more research and running the Best Practices report from the EMC, I am missing a slew of ManagementRolesAndRoleGroups from the RBAC container.
Based on your description, it seems that you have find the cause of this issue. On current situation, I still
suggest that you should run
SBS 2011 BPA and then check if can find some relevant errors. Just for a confirmation.
Meanwhile, please refer to following articles and check if can help you.
Apply

Converting Standard 2012 r2 open volume license to Standard 2008 r2 sp1 open volume license

I have 2 Standard 2012 r2 open volume license's. I wish to convert them to Standard 2008 r2 sp1. I am presently logining into Microsoft Licensing Service Center and have pulled the product key for the 2008 r2 sp1 server. The license ID
is my open volume license ID. I know I put this into the product number upon installtion. What needs to be done next for activation.

Hi
If you have Windows Server 2012 Standard edition,you will have the right to downgrade your bits to any prior version of Enterprise,Standard or Essentials editions.
MS Article;
http://download.microsoft.com/download/4/D/B/4DB352D1-C610-466A-9AAF-EEF4F4CFFF27/WS2012_Licensing-Pricing_FAQ.pdf
Follow these steps to downgrade to a previous version of Windows Server Software
1.Obtain genuine Windows media and corresponding product key for the version of Windows that is eligible for downgrade.
The media should come from a prior legally licenced version from the OEM or Retail channels.
End users WHO are licensed separately through Microsoft Volume Licensing (VL) may provide their VL media and key to a system builder to facilitate the downgrade on their own systems.
2.Insert the downgrade-eligible version of Windows media in the CD drive and follow the installation instructions.
3.Type the product key.
If the software was previously activated,you will not able to activate it online,In this case.the appropriate local Activation Support phone number will be displayed.Call the number and explain the circumstances.When it is determined that end user has an
eligible Windows licence,the customer service representative will provide a single-use activation code to activate the software.Please note that Microssoft does not provide a full product key in this scenario.
4.Activate the software.

Performance - Oracle 11.2 on same host with Virtual OS

Hi there,
a colleague of mine raised some doubts on installing Oracle database 11.2 on the same host server where multiple Virtual Box guest instances are running.
He pointed that threads allocation and consequently performance could be unbalanced.
Database server is not for production but it must supply its services for about 20 enterprise applications, so I do not expect to serve thousands of requests but definitely complex queries.
Considering these points, does it make sense what he's said?
Where can I find more information about Oracle DB 11.2 threads allocation?
thanks in advance
The host server is a DELL with two sockets Intel® Xeon® E5520, 2.26Ghz, 8M Cache, 5.86 GT/s QPI, Turbo, HT, 1066MHz Max Memory

OS RedHat 5.3If I understand what you are saying, then as far as the OS is concerned, the oracle rdbms is just another application alongside a virtual machine (or several virtual machines) process. I can't see where there should be any inherent conflict between them, except of course all processes running on any computer are competing for finite hardware resources. Typically you'd want the database server to be dedicated to running the database.

Unable to set preferred credential for host with virtual host/IP

I have installed agent on multiple hosts. For the host which has virtual IPs, I am not able to set preferred credentials or run OS commands. On other nodes, everything is fine
Please advice
Thanks

For agent i'm using 'Local System' and for preferred credentials i'm using <Domain>\<Users>. This is working fine on all other hosts but on Cluster Node its failing.
Oh yes, agent is UP.

Server 2012 r2 Hyper-v guest network speed with 10 GB NIC's

Hi
Setting up a Server 2012 r2 Hyper-v host with an onboard 4 port 1 GB nic and a offboard dual port 10 GB nic. We are using the 1gb quad port for management. The 10 Gb we intend using for hyper-v guest use however we don't seem to be able to achieve very high
speeds though the 10 GB adapter when assigned to a virtual switch. Testing the 10 Gb nic from the host confirms that we can transfer/get 10 GB speeds. When assigned to a virtual switch however the speed drops to about 1-2 Gbps. Has anybody seen anything like
this ?. We've tried a variety of settings and i can confirm that the network traffic is using the 10 GB nic.

Hi,
I am almost certain what you see is by design. I don't want to go into to much detail because I'm in a bit of a hurry. But allow me to explain.
Suppose you have a 10Gb NIC interface and an multi-core CPU. When you have RSS (Receive-Side Scaling) disabled a single core can normally handing
around 2.5-4.3Gbps. When you enable RSS the data streams/traffic is spread across multiple cores.
But RSS is a network optimization feature for the Management OS, not for a vSwitch. Instead you should use VMQ (Virtual Machine Queuing). VMQ is
the equilavant of RSS, but then intended for VMs. But... there is a difference. VMQ does not spread single data streams/traffic across multiple cores. Instead is (dynamically) assigns each vmNIC its own core. So... you don't use multiple-cores at a time for
a single vmNIC. You can't use RSS and VMQ at the same time. Keep that in mind.
But... you can accomplish this by enabling vRSS as well. That's another story.
If you watch the following video, at the end you know all about VMQ.

3 Node hyper-V 2012 R2 Failover Clustering with Storage spaces on one of the Hyper-V hosts

Hi,
We have 3x Dell R720s with 5x 600GB 3.5 15K SAS and 128 GB RAM each. Was wondering if I could setup a Fail-over Hyper-V 2012 R2 Clustering with these 3 with the shared storage for the CSV being provided by one of the Hyper-V hosts with storage spaces installed
(Is storage spaces supported on Hyper-V?) Or I can use a 2-Node Failover clustering and the third one as a standalone Hyper-V or Server 2012 R2 with Hyper-V and storage spaces.
Each Server comes with QP 1G and a DP10G nics so that I can dedicate the 10G nics for iSCSI
Dont have a SAN or a 10G switch so it would be a crossover cable connection between the servers.
Most of the VMs would be Non-HA. Exchange 2010, Sharepoint 2010 and SQL Server 2008 R2 would be the only VMS running as HA-VMs. CSV for the Hyper-V Failover cluster would be provided by the storage spaces.

I thought I was tying to do just that with 8x600 GB RAID-10 using the H/W RAID controller (on the 3rd Server) and creating CSVs out of that space so as to provide better storage performance for the HA-VMs.
1. Storage Server : 8x 600GB RAID-10 (For CSVs to house all HA-VMs running on the other 2 Servers) It may also run some local VMs that have very little disk I/O
2. Hyper-V-1 : Will act has primary HYPER-V hopst for 2x Exchange and Database Server HA-VMs (the VMDXs would be stored on the Storage Servers CSVs on top of the 8x600GB RAID-10). May also run some non-HA VMs using the local 2x600 GB in RAID-1
3. Hyper-V-2 : Will act as a Hyper-V host when the above HA-VMs fail-over to this one (when HYPER-V-1 is down for any reason). May also run some non-HA VMs using the local 2x600 GB in RAID-1
The single point of failure for the HA-VMs (non HA-VMs are non-HA so its OK if they are down for some time) is the Storage Server. The Exchange servers here are DAG peers to the Exchange Servers at the head office so in case the storage server mainboard
goes down (disk failure is mitigated using RAID, other components such as RAM, mainboard may still go but their % failure is relatively low) the local exchange servers would be down but exchange clients will still be able to do their email related tasks using
the HO Exchange servers.
Also they are under 4hr mission critical support including entire server replacement within the 4 hour period.
If you're OK with your shared storage being a single point of failure then sure you can proceed the way you've listed. However you'll still route all VM-related I/O over Ethernet which is obviously slower then running VMs from DAS (with or without virtual SAN
LUN-to-LUN replication layer) as DAS has higher bandwidth and smaller latency. Also with your scenario you exclude one host from your hypervisor cluster so running VMs on a pair of hosts instead of three would give you much worse performance and resilience:
with 1 from 3 physical hosts lost cluster would be still operable and with 1 from 2 lost all VMs booted on a single node could give you inadequate performance. So make sure your hosts would be insanely underprovisioned as every single node should be able to
handle ALL workload in case of disaster. Good luck and happy clustering :)

Unable to Install Windows Server 2012 on Windows Server 2008 R2 SP1 Hyper-V

My attempts to install are failing with a message "Windows cannot install required files. The file may be corrupt or missing....Error code: 0x800705070".
I am posting this on the Wondows 2012 Server forum but I have had exactly the same problem as described below with Windows 2008 R2 SP1.
As the title says this is on a Windows Server 2008 R2 SP1 host with all current updates. I have downloaded the ISO file from a Technet subscription file twice, once by direct download and once by the Akamai downloader. The virtual disk is connected with
the default IDE driver. I mounted both installation images as ISOs, located on a file system on the host server. I have tried installs by deleting the VM and recreating both the VM and a new virtual disk, re-using a previously created virtual disk, and
deleting the partitions in a previously created virtual disk, and executing the format command, and then attempting the install.
I have exactly the same problem trying to create a Windows Server 2008 R2 SP1 VM on the same host OS. With those attempts, I downloaded the Technet subscription iso 4 or 5 times, and burned one to a DVD which I attached to the created VM. Same
error message.
The virtual machines and virtual disks I created and used were all located on an RAID5 array, on a builtin Intel RAID controller using Intel Rapid Storage Technology software version 11.2.0.1066. The host Windows Server 2008 R2 SP1 uses this file system
but the OS is installed on a dedicated drive (C).
I had previously created a guest VM with Windows Server 2008 R2 (several months worth of updates ago) without drama.
I have spent hours reading forums and blog articles on this. A common response is to download the iso another time, and/or burn it to a DVD instead of mounting an iso image. Although I didn't do the later yet with 2012 Server, but I have done these
other steps attempting to install Windows 2008 Server SP1. The install process takes a while (not to mention doing multiple downloads). Given this seems to be a common recommended remedy, and indeed based on posts does seem to eliminate the problem is some
cases, why doesn't somebody change the Microsoft installer program so it does a thorough integrity check at the beginning of the install process?

Jeff,
After the exercise of Windows 2012 Server successfully installing (as I described above) I also successfully installed Windows 2008 R2 on Hyper-V. From my standpoint, I have eliminated the problem (which isn't the same as correcting the problem).
The answer to your specific question regarding Hyper-V support is that the motherboard I am using, an Asus P5Q, is not supported by Windows 2008 R2 because it doesn't use ECC memory, and the vendor doesn't say it supports Windows 2008. But I am sure you
know the motherboard vendors often don't test older motherboards with newer software versions. It appears that in specifying ECC memory Microsoft is trying to protect users of Windows Server from hurting themselves, not saying the software won't run.
Having said that, my suspicion in the beginning was, and still is, that it was some variable(s) left in an unknown state in the Hyper-V environment, which was why after trying to install Windows 2008 R2 several times I tried Windows 2012 which resulted in
the same error, and then encountered the same error trying to install Windows 7 on the same Hyper-V installation. The specific Hyper-V Windows 2008 R2 server had run without any operating problems for months before I started having trouble, and although it
had been quite a while since I had created VMs, that process used to work. The hardware didn't change. What changed was applying updates through Microsoft Update, and a few access control rights I changed, and at least I think, I set back to their original
value.
So in short, no, my hardware isn't supported by Windows 2008 Server. Two, your assertion that you are running the same software configuration that I am is very unlikely to be true. There are an extremely large number of things which are different between
your test system and mine, such as which Windows 2008 components are installed, what updates were installed and in what order they were installed, and what other third party software each of us is running, and between AD, and all the features, a large number
of potential differences in ACLs, options, etc. and I don't for a minute think this particular problem was caused by the underlying hardware.
I do appreciate your taking the time to try to help me, and I hope there is one thing you and I could agree on. Microsoft could pretty easily make it much easier to isolate problems. In this day and age reporting hex error codes (as opposed to doing the
table lookup in the error handling proc), and not providing more diagnostic information seems to me to be almost quaint. And in this case Microsoft can dismiss my problems on the grounds it was all on unsupported hardware. Unfortunately, I think they
are missing an opportunity to make their software better, because in my opinion what I encountered there are a set of conditions which will cause installations to fail that aren't going to get corrected.

Setting Virtual Machine's guest OS IP address from Hyper-V host returns Unspecified error (0x80004005)

Hi,
Please refer to the following post to see whether you can resolve the issue.
Network Adapter (not Legacy) does not work on Virtual Machine after installation through ISO

By the way, did you only encounter this issue with one VM or all VMs? Please do the same test on VMs with other version of Windows such as Windows Server 2008 or Windows Server 2003.

Can a SQL Server Failover Cluster Instance (FCI) be Implemented Between Two Hyper-V Hosted Virtual Machines?

I haven't had the opportunity to implement a SQL Server Failover Cluster Instance (FCI) for over 10 years and that was done with two physical, identical database servers way back in the day of Windows Server 2003 and SQL Server 2000 (old school).
Can a SQL Server 2008 R2 Failover Cluster Instance (FCI) be implemented between two Hyper-V hosted virtual machines? The environment in question already has Windows Server 2012 R2 Hyper-V hosts in place, so I'm just looking to see if this is even
possible and/or supported when utilizing virtual machines.
The client in question is currently using SQL Server 2008 R2 instances running on Win2008R2, Win2012, and Win2012R2, but I'd also be interested how this can be done or not with SQL Server 2012 or 2014 as well. Thanks in advance.
Bill Thacker

Yes, it can be done with Hyper-V guests. In fact, with Windows Server 2012 R2 Hyper-V, guests can use the Shared VHDX feature for shared storage used by Windows clusters. The guests can run Windows Server 2008 and higher provided that the Hyper-V Integration
Services are installed to support Shared VHDX. The only challenge here is making the Hyper-V hosts highly available as well, running it on WSFC.

VMM 2012 R2: error 410 / 0x80070001 when adding a new Hyper-V host. VMM Agent won't install automatically (status 1603)

I have several Windows Server 2012 R2 hosts. The OS is freshly installed, no roles/3d party software besides Hyper-V role). I also have a freshly installed VMM 2012 R2 server. They all are in the same AD domain. I want to manage those Hyper-V hosts
with this VMM instance, but I have troubles connecting those hosts to VMM.
Whenever I try to add a Hyper-V host in the VMM console, the process is stopped almost immediately after it starts. The failing step is "1.2 Install Virtual Machine Manager Agent". The final error message is as follows:
Error (410)
Agent installation failed on XXX.
Incorrect function (0x80070001)
Recommended Action
Try the operation again. If the problem persists, install the agent locally and then add the managed computer.
If I try to install the agent manually copied from the VMM host (C:\Program Files\Microsoft System Center 2012 R2\Virtual Machine Manager\agents\amd64\3.2.7634.0
as of now) by just clicking on its MSI file in Windows Explorer (and agreeing to the Windows prompt to run it with elevated privileges), the installation fails as well with "Installation success or error status: 1603." in the
server Application log.
The only way I found to install the agent is to run the installation from command prompt with elevated privileges. In this case the installation finishes successfully, and I can add the host to VMM by marking the "Reassociate the host" checkbox
in the VMM wizard.
Why is it so? Isn't the agent supposed to install without manual intervention? As I recall, I had no such problem with previous versions of Windows Server and VMM.

I brought up the share because it is off by default with Hyper-V Server as well as a Core installation. Regardless of the Firewall policy involved.
Maybe, but I don't work with pure Hyper-V and Core servers. I have a full-fledged Windows Server 2012 R2 Datacenter.
You're correct that File Server role is not enabled by default, this is my mistake. I open SMB-IN port manually (with the help of a group policy), and Windows considers it to be am equivalent of the enabled File Server role. Nonetheless, ADMIN$ share is
always accessible in my environment (and without it, for example, I wouldn't be able to remotely install things like SCOM Agent which installs without a glitch). Just in case I manually installed the File Server role, and it didn't help.
What you say about multihomed servers is interesting. The servers in question do have multiple network interfaces, but at the time I tried to install the VMM Agent only one of them (a designated host management / network access interface) had a real IP address.
Two other interfaces were non-configured (I apply a virtual switch configuration after the VMM Agent is installed). Just in case I disabled them when tried to install the VMM Agent remotely on the last host, and the installation still failed immediately
after start. Anyways, after the VMM Agent is installed manually the host can be normally re-associated with VMM, so it's doubtful that I have a network issue.
And, of course, there is no 3d-party software on the hosts (no antiviruses/firewalls in particular) except the EMC Unisphere Host Agent (a piece of software necessary for connecting a host to an EMC storage system) and networking drivers. Actually,
this is a pure Microsoft environment.
So I still believe that is has something to do with the Windows Installer inability to configure Windows Firewall policy after being invoked from Windows Explorer with a double-click on a MSI file. But I don't know how to strictly confirm it.

Backup fails for a Hyper-V guest with VSS Writer failures using DPM 2012 R2 - Hyper-V guest has Oracle application installed,

I am trying to backup a VM which before it had Oracle installed backed up with no problems. It is a Windows 2008 R2 server which sites on an 8 node Hyper-V 2012 R2 cluster (with CSVs). I am using DPM 2012 R2 to run the backups which have been
successful for the last few weeks but then Oracle was installed and the backups have failed since then.
The job fails and a large number of VSS writers go into a 'Failed' state with the 'Last Error' showing as 'Timed out'. I then get 4 popups appear each referring to a 'temporary' drive which appears briefly in Disk Management with a RAW file system.
These pops say "You need to format the disk in drive X: before you can use it. Do you want to format it?" (where
X: is replaced by the drive letter assigned to each 'temporary' drive).
The System event log is populated with a large number of warnings with Event 51, Disk, stating "An error was detected on device \Device\Harddisk<number>\DR<number> during a paging operation". There are also a
few warnings for Ntfs (eventid 57) stating that "The system failed to flush data to the transaction log. Corruption may occur."
Prior to these warnings there are 5 other warnings for partmgr (eventid 58) stating "The disk signature of disk
<number x> is equal to the disk signatuire of disk <number y>" and 4 errors (eventid 1, VDS Basic Provider), "Unexpected failure. Error code: 490@01010004".
There is a script which is run to stop the Oracle application on the server and if this is run then the backups will complete successfully. We have been troubleshooting this by running a certain amount of the script and seeing which part affects the
backup and it seems that if the Weblogic (wls_reports) service is stopped then the backup will succeed but if it is running then the backup will fail and the above symptoms occur.
Another point which may help is that there is a pre-production server which resides on a Windows 2008 R2 Hyper-V standalone server, has the same scripts and installation of Oracle but backs up without any issues.
I have experienced VSS writer failures before with VM backups but I have not seen this before. It is not intermittent and I can find no work around to alleviate the problem of having no backup (except stopping this service or shutting the server down,
but as it is a production server this is not practical).
If anyone has experienced this before or have any suggestions / advice it would be much appreciated.
Thanks
Chris

Hi Chris
I have exactly the same issue.
2008 R2 Server running Oracle
6 node 2012 R2 Hyper-V Cluster with CSV
Exact same errors and popup "format disk" message.
DPM2012 R2
I also have some other VM's on the same cluster which do back up through DPM
The only difference I can see is the server which has the issue has a legacy network adapter.
Production server so cannot make any changes until later but will add new adapter and report back.
Interesting about the Weblogic service, may test this also.
Cheers
Kev.
