Server 2012 Hyper-V locks up Virtual Server for no reason.

Server 2012 Hyper-V locks up virtual servers for no reason.
This is a production server. I began building this server in February. I installed the server in November. 2012 server R1 is full of bugs!
First who was the rocket scientist that decided that the TURN OFF function in Hyper-V means "Please turn off when the
F*#@$*% you feel like it"? Idiots!
I have a Supermicro server with perfect memory (for those who want to blame this on memory).
It is running 12 Virtual Servers. Every morning, at a random time, at least 1 of the servers lock up solid. Sometimes as many as 5 decide that for no reason they all want to lock up. The servers that lock up may be 1 or more: a database server, a terminal
server, an exchange server, a Windows 8.1 Ent VDI server, an IIS server, and or AD server. All 2012 R1.
They are running all current Microsoft and other vendor patches and hardware updates.
The only common denominator is the Hyper-V server.
I cannot shut them down using the Hyper-V manager. I cannot turn them off. I have a hundred users standing by while I nicely ask them to turn off. The VM will turn off after 20 minutes and a lot of gentle coaxing.
I cannot Kill the vmwp.exe process associated with the locked Virtual Machine.
No .DMP are created. No events in the event viewers. No reason at all. When they restart, there is no indication of a problem.
I ran two VMWP dumps and posted it here.
www.a1bcs.com/hyper-vlockup.zipx
Does anyone know why these are locking up?
Thanks in advance for any help.
Robert

I'm not positive of the cause but I was able to stop the problems.
It turned out that Network Load Balancing (NLB) between the two terminal servers and another between the two gateways was causing the lockups.
This is a normal configuration and it should work. Especially since Microsoft has seen fit to remove the DRAIN USERS function from RDP as well as the LOCK OUT till next reboot function. JUST FYI these functions are still available at a DOS prompt
by using the CHGLOGON command. But still the NLB also provides these functions.
Anyhow, once I removed the NLB I haven't had the lockups anymore.
That doesn't however change the fact that TURN OFF should mean TURN OFF not turn off please!
Thanks again,
Robert

Windows Server 2012 - Hyper-V - Cluster Sharded Storage - VHDX unexpectedly gets copied to System Volume Information by "System", Virtual Machines stops respondig

We have a problem with one of our deployments of Windows Server 2012 Hyper-V with a 2 node cluster connected to a iSCSI SAN.
Our setup:
Hosts - Both run Windows Server 2012 Standard and are clustered.
HP ProLiant G7, 24 GB RAM. This is the primary host and normaly all VMs run on this host.
HP ProLiant G5, 20 GB RAM. This is the secondary host that and is intended to be used in case of failure of the primary host.
We have no antivirus on the hosts and the scheduled ShadowCopy (previous version of files) is switched off.
iSCSI SAN:
QNAP NAS TS-869 Pro, 8 INTEL SSDSA2CW160G3 160 GB i a RAID 5 with a Host Spare. 2 Teamed NIC.
Switch:
DLINK DGS-1210-16 - Both the network cards of the Hosts that are dedicated to the Storage and the Storage itself are connected to the same switch and nothing else is connected to this switch.
Virtual Machines:
3 Windows Server 2012 Standard - 1 DC, 1 FileServer, 1 Application Server.
1 Windows Server 2008 Standard Exchange Server.
All VMs are using dynamic disks (as recommended by Microsoft).
Updates
We have applied the most resent updates to the Hosts, VMs and iSCSI SAN about 3 weeks ago with no change in our problem and we continually update the setup.
Normal operation:
Normally this setup works just fine and we see no real difference in speed in startup, file copy and processing speed in LoB applications of this setup compared to a single host with two 10000 RPM Disks. Normal network speed is 10-200 Mbit, but occasionally
we see speeds up to 400 Mbit/s of combined read/write for instance during file repair.
Our Problem:
Our problem is that for some reason a random VHDX gets copied to System Volume Information by "System" of the Clusterd Shared Storage (i.e. C:\ClusterStorage\Volume1\System Volume Information).
All VMs stops responding or responds very slowly during this copy process and you can for instance not send CTRL-ALT-DEL to a VM in the Hyper-V console, or for instance start task manager when already logged in.
This happens at random and not every day and different VHDX files from different VMs gets copied each time. Some time it happens during daytime wich causes a lot of problems, especially when a 200 GB file gets copied (which take a lot of time).
What it is not:
We thought that this was connected to the backup, but the backup had finished 3 hours before the last time this happended and the backup never uses any of the files in System Volume Information so it is not the backup.
An observation:
When this happend today I switched on ShadowCopy (previous files) and set it to only to use 320 MB of storage and then the Copy Process stopped and the virtual Machines started responding again. This could be unrelated since there is no way to see
how much of the VHDX that is left to be copied, so it might have been finished at the same time as I enabled ShadowCopy (previos files).
Our question:
Why is a VHDX copied to System Volume Information when scheduled ShadowCopy (previous version of files) is switched off? As far as I know, nothing should be copied to this folder when this functionis switched off?

Please only answer our question and do not offer any general optimization tips that do not directly adress the issue! We want the problem to go away, not to finish a bit faster!

Hallo Lawrence!
Thankyou for youre reply, some comments to help you and others who read this thread:
First of all, we use Windows Server 2012 and the VHDX as I wrote in the headline and in the text in my post. We have not had this problem in similar setups with Windows Server 2008 R2, so the problem seem to be introduced in Windows Server 2012.
These posts that you refer to seem to be outdated and/or do not apply to our configuration:
The post about Dynamic Disks:
http://technet.microsoft.com/en-us/library/ee941151(v=WS.10).aspx is only a recommendation for Windows Server 2008 R2 and the VHD format. Dynamic VHDX is indeed recommended by Microsoft when using Windows Server 2012 (please look in the optimization guide
for Windows Server 2012).
Infact, if we use fixed VHDX then we would have a bigger problem since fixed VHDX are generaly larger then Dynamic Disks, i.e. more data would be copied and that would take longer time = the VMs would be unresponsive for a longer time.
The post "What's the deal with the System Volume Information folder"
http://blogs.msdn.com/b/oldnewthing/archive/2003/11/20/55764.aspx is for Windows XP / Windows Server 2003 and some things has changed since then. for instance In Windows Server 2012, Shadow Copies cannot be controlled by going to Control panel -> System.
Instead you right-click on a Drive (i.e. a Volume, for instance the C drive/Volume) in Computer and then click "Configure Shadow Copies".
Windows Server 2008 R2 Backup problem
http://social.technet.microsoft.com/Forums/en/windowsbackup/thread/0fc53adb-477d-425b-8c99-ad006e132336 - This post is about the Antivirus software trying to scan files used during backup that exists in the System Volume Information folder and we do not
have any antivirus software installed on our hosts as I stated in my post.
Comment that might help us:
So according to “System Volume Information” definition, the operation you mentioned is Volume Shadow Copy. Check event viewer to find Volume Shadow Copy related event logs and post them.
Why?
Furhter investigation suggests that a volume shadow copy is somehow created even though the Schedule for Shadows Copies is turned off for all drives. This happens at random and we have not found any pattern. Yesterday this operation took almost all available
disk space (over 200 GB), but all the disk space was released when I turned on scheduled Shadow Copies for the CSV.
I therefore draw these conclusions:
The CSV Volume has about 600 GB of disk space and since Volume Shadows Copy used 200 GB, or about 33% of the disk space, and the default limit is 10% then I conclude that for some reason the unscheduled Volume Shadow Copy did not have any limit (or ignored
the limit).
When I turned on the Schedule I also change the limit to the minimum amount which is 320 MB and this is probably what released the disk space. That is, the unscheduled Volume Shadow Copy operation was aborted and it adhered to the limit and deleted the
Volume Shadow Copy it had taken.
I have also set the limit for Volume Shadow Copies for all other volumes to 320 MB by using the "Configure Shadow Copies" Window that you open by right clicking on a drive (volume) in Computer and then selecting "Configure Shadow Copies...".
It is important to note that setting a limit for Shadow Copy Storage, and disabaling the Schedule are two different things! It is possible to have unlimited storage for Shadow Copies when the Schedule is disabled, however I do not know if this was the case
Before I enabled Shadow Copies on the CSV since I did not look for this.
I now have defined a limit for Shadow Copy Storage to 320 MB on all drives and then no VHDX should be copied to System Volume Information since they are all larger than 320 MB.
Does this sound about right or am I drawing the wrong conclusions?

There is something strange about the limits on the Secondary host!
I have not in any way changed the settings on the Secondary host and as you can see, the Secondary host has a maximum limit of only 35 MB storage on the CSV, but it also shows that this is 10% of the Volume. This is clearly not the case since 10% if 600
GB = 60 GB!
The question is, why does it by default set a too small limit (i.e. < 320 MB) on the CSV and is this the cause of the problem? I.e. is the limit ignored since it is smaller than the smallest amount you can provide using the GUI?
Is the default 35 MB maximum Shadow Copy limit a bug, or is there any logical reason for setting a limit that according to the GUI is too small?

Windows Server 2012 - Hyper-V - iSCSI SAN - All Hyper-V Guests stops responding and extensive disk read/write

We have a problem with one of our deployments of Windows Server 2012 Hyper-V with a 2 node cluster connected to a iSCSI SAN.
Our setup:
Hosts - Both run Windows Server 2012 Standard and are clustered.
HP ProLiant G7, 24 GB RAM, 2 teamed NIC dedicated to Virtual Machines and Management, 2 teamed NIC dedicated to iSCSI storage. - This is the primary host and normaly all VMs run on this host.
HP ProLiant G5, 20 GB RAM, 1 NIC dedicated to Virtual Machines and Management, 2 teamed NIC dedicated to iSCSI storage. - This is the secondary host that and is intended to be used in case of failure of the primary host.
We have no antivirus on the hosts and the scheduled ShadowCopy (previous version of files) is switched of.
iSCSI SAN:
QNAP NAS TS-869 Pro, 8 INTEL SSDSA2CW160G3 160 GB i a RAID 5 with a Host Spare. 2 Teamed NIC.
Switch:
DLINK DGS-1210-16 - Both the network cards of the Hosts that are dedicated to the Storage and the Storage itself are connected to the same switch and nothing else is connected to this switch.
Virtual Machines:
3 Windows Server 2012 Standard - 1 DC, 1 FileServer, 1 Application Server.
1 Windows Server 2008 Standard Exchange Server.
All VMs are using dynamic disks (as recommended by Microsoft).
Updates
We have applied the most resent updates to the Hosts, WMs and iSCSI SAN about 3 weeks ago with no change in our problem and we continually update the setup.
Normal operation
Normally this setup works just fine and we see no real difference in speed in startup, file copy and processing speed in LoB applications of this setup compared to a single host with 2 10000 RPM Disks. Normal network speed is 10-200 Mbit, but occasionally
we see speeds up to 400 Mbit/s of combined read/write for instance during file repair
Our Problem
Our problem is that for some reason all of the VMs stops responding or responds very slowly and you can for instance not send CTRL-ALT-DEL to a VM in the Hyper-V console, or for instance start task manager when already logged in.
Symptoms (i.e. this happens, or does not happen, at the same time)
I we look at resource monitor on the host then we see that there is often an extensive read from a VHDX of one of the VMs (40-60 Mbyte/s) and a combined write speed to many files in \HarddiskVolume5\System Volume Information\{<someguid and no file extension>}.
See iamge below.
The combined network speed to the iSCSI SAN is about 500-600 Mbit/s.
When this happens it is usually during and after a VSS ShadowCopy backup, but has also happens during hours where no backup should be running (i.e. during daytime when the backup has finished hours ago according to the log files). There is however
not that extensive writes to the backup file that is created on an external hard drive and this does not seem to happen during all backups (we have manually checked a few times, but it is hard to say since this error does not seem leave any traces in event
viewer).
We cannot find any indication that the VMs themself detect any problem and we see no increase of errors (for example storage related errors) in the eventlog inside the VMs.
The QNAP uses about 50% processing Power on all cores.
We see no dropped packets on the switch.
(I have split the image to save horizontal space).
Unable to recreate the problem / find definitive trigger
We have not succeeded in recreating the problem manually by, for instance, running chkdsk or defrag in VM and Hosts, copy and remove large files to VMs, running CPU and Disk intensive operations inside a VM (for instance scan and repair a database file).
Questions
Why does all VMs stop responding and why is there such intensive Read/Writes to the iSCSI SAN?
Could it be anything in our setup that cannot handle all the read/write requests? For instance the iSCSI SAN, the hosts, etc?
What can we do about this? Should we use MultiPath IO instead of NIC teaming to the SAN, limit bandwith to the SAN, etc?

Hi,
> All VMs are using dynamic disks (as recommended by Microsoft).
If this is a testing environment, it’s okay, but if this a production environment, it’s not recommended. Fixed VHDs are recommended for production instead of dynamically expanding or differencing VHDs.
Hyper-V: Dynamic virtual hard disks are not recommended for virtual machines that run server workloads in a production environment
http://technet.microsoft.com/en-us/library/ee941151(v=WS.10).aspx
> This is the primary host and normaly all VMs run on this host.
According to your posting, we know that you have Cluster Shared Volumes in the Hyper-V cluster, but why not distribute your VMs into two Hyper-V hosts.
Use Cluster Shared Volumes in a Windows Server 2012 Failover Cluster
http://technet.microsoft.com/en-us/library/jj612868.aspx
> 2 teamed NIC dedicated to iSCSI storage.
Use Microsoft MultiPath IO (MPIO) to manage multiple paths to iSCSI storage. Microsoft does not support teaming on network adapters that are used to connect to iSCSI-based storage devices. (At least it’s not supported until Windows Server 2008 R2. Although
Windows Server 2012 has built-in network teaming feature, I don’t article which declare that Windows Server 2012 network teaming support iSCSI connection)
Understanding Requirements for Failover Clusters
http://technet.microsoft.com/en-us/library/cc771404.aspx
> I have seen using MPIO suggests using different subnets, is this a requirement for using MPIO
> or is this just a way to make sure that you do not run out of IP adressess?
What I found is: if it is possible, isolate the iSCSI and data networks that reside on the same switch infrastructure through the use of VLANs and separate subnets. Redundant network paths from the server to the storage system via MPIO will maximize availability
and performance. Of course you can set these two NICs in separate subnets, but I don’t think it is necessary.
> Why should it be better to not have dedicated wireing for iSCSI and Management?
It is recommended that the iSCSI SAN network be separated (logically or physically) from the data network workloads. This ‘best practice’ network configuration optimizes performance and reliability.
Check that and modify cluster configuration, monitor it and give us feedback for further troubleshooting.

Windows Server 2012 Hyper-V network latencies

Hi All,
I have an issue with our Windows Server 2012 Hyper-V hosts that I can't seem to figure out. Situation:
2 x Dell PowerEdge R815 servers with AMD opteron 6376 16 core CPU's and 128 GB RAM running Windows Server 2012 with Hyper-V.
2 virtual machines running on the same physical host and connected to the same virtual switch show high TCP connection latencies. One virtual machines runs a SQL Server 2012 database instance and a Dynamics AX 2012 R2 instance. The other machine a
SharePoint 2013 instance and the AX client. We see latencies of 20ms and higher on most of the TCP connections that are made from the sharepoint machine to the sql server machine.
At first I thought it might have something to do with the physical NIC's. It turned out that VMQ wasn't correctly supported by the firmware of the Broadcom BCM5709c cards. By default this setting is enabled. Turning off the VMQ setting somewhat improved
the situation but the latencies are still at 8ms and higher.
What I don't understand is what influence enabling/disabling VMQ should have on network performance. As I understand it now virtual machines connected to the same virtual switch bypass the physical altogether. Another point is that VMQ should actually improve
performance, not decrease it.
Another question I have is about the various tcp offloading settings on the physical NIC's. After installing the new firmware and drivers from Dell most of these settings are set to disabled. The documents I have been able to find talk about Windows Server
2008, any thought how these settings relate to Windows Server 2012 and whether they should be enabled?
Thanks in advance for your time and thoughts
Kind regards,
Dennes Schuitema

Hi Denes,
Please try to update your BroadCom NIC driver version ,the newest version should be 7.8.51

Sharepoint 2013 SSRS Interaction with Sql Server 2012 Reporting Services connecting to Sql Server 2008 R2 database

Hi
I'm working on upgrading sharepoint 2010 to sharepoint 2013 with sql server 2008 r2. I've ran into some problems but have been able to get a test farm upgraded. However to run SSRS 2013 it seems Sql Server 2012 Reporting Services are required. Upgrading
to a full sql server 2012 database isn't an option. I know that sql server 2012 reporting services can use sql server 2008 r2 as a catalog and content database so I was wondering could this be a workaround? Importantly would I need a separate machine/virtual
machine to host sql server 2012 reporting services? or could it live on the sql server 2008 r2 machine? Any pointers appreciated. Thanks Dan

Remember that SSRS must be deployed on the SharePoint server. Having said that, yes you can install SSRS 2012 SP1 on a server running SQL 2008 R2. And yes, you can use 2008 R2 as your Database Engine server while SSRS 2012 SP1 runs on the SharePoint server.

Is it possible to create a two node cluster with SQL server 2012 STD on node1 and SQL Server 2008 ENT on node2 on a Windows server 2012?

Hi All,
Is it possible to create a two node cluster with SQL server 2012 STD on node1 and SQL Server 2008 ENT on node2 on a Windows server 2012?
aa

I think you are confused with the way cluster is installed. Installing SQL on cluster is a two step process. On first node you create a new SQL cluster and on second node you need "AddNode" action.
Same edition media has to be used in above two operation.
you can install two separate instances with one enterprise and one standard.

Virtual server is already managed by another virtual server pool

I was trying to register a server to a server pool on OEM 10.2.0.5 console, on the first try it never completed the registration, it errored out. After doing 'clear operation error' I try to register the same server, Now I get "virtual server is already managed by another virtual server pool". Does any one ran into similar situation? How do I clear this? Thank you.

How do I clear this? Thank you.It's fairly simple to clear. First, stop the ovs-agent on the server:
# service ovs-agent stopThen, remove the local ovs-agent database:
# rm -rf /etc/ovs-agent/db Then, start the agent again:
# service ovs-agent startThe agent will now be reset back to an unconfigured state.

Can we use SQL Server 2012 Web Edition as a witness server in mirroring?

Hi All,
Can we use SQL Server 2012 Web Edition as a witness server in mirroring?
Grateful to your time and support. Regards, Shiva

Hi All,
Can we use SQL Server 2012 Web Edition as a witness server in mirroring?
Grateful to your time and support. Regards, Shiva
As Per BOL
We strongly recommend that the witness reside on a separate computer from the partners. Database mirroring partners are supported only by SQL Server 2005 Standard and later versions and by SQL Server 2005 Enterprise Edition and later versions.
Witnesses, in contrast, are also supported by SQL Server 2005 Workgroup and later versions and by SQL Server 2005 Express Edition and later versions. Except during an upgrade from an earlier version of SQL Server, the server instances in a
mirroring session must all be running the same version of SQL Server. For example, a SQL Server 2005 witness is supported when you are upgrading from a SQL Server 2005 mirroring configuration but cannot be added to an existing or new SQL Server 2008 or later
mirroring configuration.
A witness can run on any reliable computer system that supports any of these editions of SQL Server. However, we recommend that every server instance that is used as a witness correspond to the minimum configuration that is required for the SQL Server Standard
version that you are running. For more information about these requirements

In iTunes I click on a song and when I click on the "get info" tab, it opens up but everything is gray - locked, therefore, I cannot edit the year or genre of the songs. Not every song is locked, only certain ones for some reason. Any help?

In iTunes I click on a song and when I click on the "get info" tab, it opens up but everything is gray - locked, therefore, I cannot edit the year or genre of the songs. Not every song is locked, only certain ones for some reason. Any help?

I ran into the same problem, I think that, If you tab on a song that is on your IPOD, and the song data is grayed-out, I think it means that the song is probably twice on your IPOD and that the iTunes directory can not edit THAT song data for two (or more) files @once. Check if this is the case, sinceI have the same problem,am looking for a way to have One and the same song in more playlists but only keep the song once on the IPOD.

Is it possible to install SQL Server 2012 Standard Edition on a Windows Server 2012 Standard Which is installed on a Virtual Machine that is created by Hyper-V?

Hi
I have recently bought a Virtual Machine from a data center and installed a Windows Server 2012 Standard Edition on it. As I tried to install the SQL Server 2012 Standard Edition, the data center administrator denied me to do this telling me it is not possible
to install any licensed Microsoft software on a Windows installed on virtual machine created by Hyper-V. It was really strange for me! I wanna know if this is true.
Thanks Everybody

Hi Farid,
For SQL server running on virtual server please refer to following article :
http://blogs.technet.com/b/peeyusht/archive/2010/03/19/sql-licensing-under-virtualization.aspx
In addition , for license issue we still recommend you to contact MS Activation Center:

Running Server 2012 R2 Guest on Server 2012 Hyper-v

Hi,
I'm wondering if anyone's been able to find any information on whether or not this is supported. We want to run some R2 virtual machines but aren't ready to upgrade hosts from 2012 to 2012 R2. I know that back in the 2008 R2 days, a hotfix was released
to support 2012 guests. I'm wondering if there are any plans for this or if one is even required.
I was able to install a R2 VM (I told wizard it was running 2012), but that's not quite the same as it being supported.
I'm also wondering if anyone's come across any good documentation or info upgrading SCVMM + Server 2012 with hyper-v cluster to the R2 versions. The info on TechNet seems pretty sparse at the moment.
Thanks

Hi,
The Server 2012 as the guest system in 2012 Hyper-v was supported with no additional hotfix.
For the Hyper-V cluster upgrade please attention the following hotfix:
Update that improves cluster resiliency in Windows Server 2012 is available
http://support.microsoft.com/kb/2838669
Recommended hotfixes and updates for Windows Server 2012-based Failover Clusters

Server 2012 File Preview Locks Files

Hi everybody,
I recently reinstalled one of my customers server.
The previous installation was Server 2008 Foundation running RDS and the new installation Server 2012R2 Foundation (RDS).
With the previous installation it was possible to use the file preview for documents like Word and Excel or PDF in the explorer, and while these files were openend it was possible to delete them or move them.
With the new installation on Server 2012 it's not possible to delete or move these files when they are shown in the explorer preview.
Any ideas?
There is also another issue, it should be possible to preview saved e-mail (*.msg) conversations with the Windows Explorer when the 32-bit "Outlook 2013 / Office" version has been installed
This also doesn't work, the preview handler has not been made for x64 but for the x86 it should work. But it doesn't show the messages in the explorer.
Kind regards,
Tim

Hi Tim,
Turns out there is no Windows Server 2012 R2 foundation in our lab, I have tested this on a Windows 8.1 machine.
In my tests, there is no issue to delete Word and Excel files when there are in the Preview Pane, and saved email conversations can be viewed through the Preview Pane, also can be deleted.
As for PDF file, the Preview Pane is unavailable.
The preview of *.msg files still doens't work in the explorer.
I'm thinking that the Kerio plugin for Outlook is creating this issue...
Do you also have the same issue on other machines?
Regarding Outlook related issues, I suggest you also refer to experts from Outlook forums to see if they have more insights.
