Hello

I have a stand alone win08R2 which I would like to convert and then add to my Hyper-V server.

win08R2: dell precision with mirrored HDD.  HDD is partitioned into 2 partitions (d and D)

win2012 R2: hyper-V is a dell R610 Raid 1 (2drives) raid 0 (4 drives)

disk2vhd is completes no errors, but on boot it blue screens and then reboots into recovery mode:

I have tried the following fixes and nothing seems to work:

among a few others.. similar but no luck.

can anyone direct me to a better solution??


BSOD system_thread_excption_not_handled (WppRecorder.sys)

have installed windows 2012 R2,  all have been working fine and installed a Hyper-v server which am have install AD, DNS, DHCP which has been working grate.

after install an update on virtual server I rebooted and now am receiving a BSOD system_thread_excption_not_handled (WppRecorder.sys)

and it not allowing me to access anything. 

I have look into the firmware setting on the virtual server  and noticed file type called bootmgfw.efi on the firmware virtual setting.  which details 

Description: Windows Boot Manager

Value: \HD(2,GPTBA6F9016-9039-4EED-95D7-7C9DFDA947F4,77056,66560)\EFI\Microsoft\Boot\bootmgfw.efi

am using a physical hard disk which I have created using virtual disks which is offline and I have other Hyper-v Virtual server which are using the same settings and it working fine.

can anyone help me with this issue?

Many thanks,

Is there a work around for this issue which will let us fix VMs with the issue in situ?

http://support.microsoft.com/kb/2979256

Also - if i understand the problem correctly, we are not meant to upgrade the Integration Components of 2012 R2 VMs via offline servicing at all? What if there is an upgraded needed? What are the best practice methods? 

Cheers.

Recommendations for Sizing Hyper-V

0

Hi there,

I've two servers http://www8.hp.com/emea_middle_east/en/products/proliant-servers/product-detail.html?oid=5195898 with 128GB Memory and 4 Gigabit Ethernet.

I want to run multiple AD instances, File Server, SQL, Exchange & Sharepoint on it. Data will be on a SAN. We've around 100 users. Other than Exchange, rest of the roles have minimal load. e.g., SQL is only for supporting management and monitoring systems. is it OK if I run each VM on RAID 0 disk? My theory is that if a disk fails, the service will resume from the other server. It's difficult to assess the current load of servers as there are many under different domains and stand alone systems as well. My plan is to consolidate them all. Running Hyper-V from USB is a recommended practice or is it supported only development systems? It would help me use one more disk for VM if I can run Hyper-V from USB in production. I understand that AD 2012 R2 is fully supported on VMs now. The old recommendation of having the primary DC on a physical server still valid? Our is a small setup.

I'm sure many of you have gone through these scenarios. Please share your experiences. Also if there are easy to follow books or articles on these subject, please point that out too.

Thanking you,

Shereef

Manager Hyper-V Server from Another Subnet

0
0

I have a bunch of Hyper-V servers sitting on a separate vlan and they have their own special subnet.

I used to be able to install Hyper-V Manager on my desktops and simply specify the Hyper-V servers and manage them remotely however, recently they do not allow me to communicate with them if I am sitting within a different vlan / subnet. 

They Hyper-V servers firewalls are disabled, the VLAN firewall rules allow for full connectivity between my management PCs to the Hyper-V servers so I know it's not anything to do with firewall policies.

Something on the Hyper-V server is not allowing me to administer it. I have added an additional NIC to my management PC which I stuck a leg into the other VLAN by adding an IP without a gateway to it and it allows me to administer it remotely. So I now know for fact that it has something to do with the different subnet.

I really need some help here as adding NICs to administer the servers is simply not an option.

Thank You!

Issues with continued use of Shared VHDx

0
0

Hi all,

I have been struggling to get Shared VHDx to work properly for the last week or so.  I have a two 2012 R2 file server VMs clustered sitting on a Windows Server 2012 R2 Hyper-V cluster, I would like to use Shared VHDx for the Quorum Disk Witness and for the File server cluster storage.

Initially when I first create, share and add the VHDx to the two file servers it works without an issue, the file server cluster role will live migrate and storage stays accessible.  However after a period of time e.g. overnight if either of the servers are shutdown/restarted they will not restart.  The error I receive is:

'FS1B' failed to add device 'Virtual Hard Disk'.

Failed to open attachment
'Path to disk\Quorum.vhdx'. Error: 'The request is not supported'.

'FS1B': Cannot get information for attachment 'Path to disk\Quorum.vhdx'.

Failed to open attachment 'Path to disk\Quorum.vhdx'. Error: 'The request is not supported.'.

I have searched around online and came across a couple of people with a similar issue, one fixed it with adjusting his Network Binding (this did not help me).  If I turn off the sharing on the VHDx the server it is attached to will boot fine.

I have also made sure the networking and storage access to the Hyper-V hosts are identical and that all four servers are up to date patching wise.

I don't think I'm missing anything but it really doesn't want to work and driving me a little nuts.

Thanks!

Hi ,

we have configure windows teaming on the hyper-v host 2012 R2 , and creating virtual swich on the teaming interface

when i assign a  Virtual machine to  that switch , i get latency for browsing the websites inside the VM and  time out error

if i assign the virtual switch to non team adapter  , there is no error and no latency

Do you know why the window teaming do latency ?

Remove "Ghost" Virtual Switch

0
0

Hi 

I'm currently having an issue regarding virtual switches in Hyper-V on Windows Server 2012R2.

When i try to add a Hyper-V server as a new node in the Cluster manager, I  get error during the verification.

The tests claims that the host I'm trying to add has several virtual switches. But those switches has been removed from the host.

I have reconfigured the network adapters and even tried to reinstall Hyper-V on the host, but the error remains.

Anyone who knows where the configuration for the virtual switches is stored, and if it is possible to remove the "ghost" switches manually?

Thanks

Server 2012 R2 Hyper-V cluster nodes BSOD

We have an 11 node Hyper-V cluster running Server 2012 R2 with all latest updates.

We have had an ongoing issue with nodes BSODing or hanging. 

Specs:

Hyper-V Nodes-

128-256GB of RAM per node, depending on generation. 12-32 cores. None of the machines are starving for resources. We have a cluster setup through SC VMM 2012 R2 that optimizes the VMs every 30 minutes. The vhd's for VM's sit in a SMB 3.0 share hosted by a SOFS cluster w/ Storage Spaces on a JBOD. Each Hyper-V host utilizes 2 x10Gb Intel NIC cards (either X520-T2 or X540-T2 depending on node) in a NIC team that is currently set to active-standy

We have tried:

adjusting VMQ settings so each NIC uses different cores

Switching NIC team from Active-Active to Active-Standby.

Hyper-V could not replicate changes for virtual machine 'VM007': There is not enough space on the disk. (0x80070070)

0

Ok. Had a completely successful replication setup 2 days ago and now I don't. I have a 5 node (ProdCluster) and a 3 node DRCluster) that I just got done setting up for Hyper-V replication. . As I stated everything worked fine, but I realized that my volume setup on the SAN would not work for me. So I shut down the replica broker, removed the CSV from failover manager and removed the volumes. I set up a new 15 tb volume that was going to be the sole volume for my replicas on the DR side. I formatted the volume. Added it to failover manager. Set it as CSV. Pointed the replica broker to it and have not been able to replicate ever since. Also, I am left with the undeleteable .xml files for each VM that an attempt was made on and cannot find the process that is using it. Tried shutting down VMM as I had read that VMM could be the culprit. I'm not sure if the issues or related and obviously the disk size failing the replication is the major issue. An 80gb test VM couldn't possibly fill up a 15tb volume. Help.

Virtual Network Adapter Not Working

0

Hi

I have added an external virtual switch that points to my WIFI card on the host, I have tried checking/unchecking 'allow managment operating system to share this adapter' and I have added the network adapter in the virtual machine settings.

However no network adapters come up in my VM for some reason.

Networking works in the host OS fine. I am trying to use my hosts wifi configuration for the virtual machine.

I'm unsure what else to try, the guest is Windows XP pro and the host is windows 10

Using Hyper-V replica for DR

0
0

Hi All,

Looking for a bit of advise/guidance re using Hyper-V replica to setup a DR environemnt.  I have a clustered Hyper-V environment running AD, Exchange and a couple of databases. Basically what I was hoping to do was use Hyper-V replica to replicate the VM's to another stand alone Hyper-V server (still part of AD just non clustered) and then have these available should our primary site go offline.

Does anyone have experience on this and think it is the right solution to use for this? Any issues people have run into in the past would be much appreciated so I know what I am up against when trying to set this up. 

Thanks

Hyper V what to do to maintain?

0
0

Hello everybody

We sold an HyperV Cluster to one of our customers it was a promotion from HP. The customer got a 2 node cluster with a HP  MSA on this we installed Windows Server 2008R2 and installed the Hyper V role.

On this there are several virtual machines running now our boss was able to persuade the customers that he needs a support contract or better a maintain contract.

We what do we need to main when this thing runs? :-) The system is not connected to the internet and it's not allowed to connect to it because it resides in a bank.

So the questions:

1) What to check (logs, paritions, CPU, RAM, Role?)

2) What to update? Windows Only other componets=

3) How to find out which updates are missing when i can't use the internet?

4) How to get the updates and how to bring them to the system and install?

5) Way to backup situation before install? Disaster Recovery? 

I know this sounds stupid but i really don't know how to handle this.

Best regards

Michael


Host vs Guest disk performance

0
0

I've got a disk performance issue in my HV cluster. I have 2 ibm x3850 x6's clustered running server 2012 R2 with and IBM XIV connected via 8gb fiber channel.  When I run my SQLIO test from the host to XIV drive (CSV or drive letter), I get 180,000 iops / 1300MB throughput.  When I run the same test from a guest VM with its vhdx on the same CSV, I get 30,000 iops and 250MB throughput. 

My guest VM is server 2012R2 (gen2, fresh install).  Where it gets even more interesting is that when I do a passthrough disk to the same VM, I get 90,000 iops / 700 MB throughput.  Everything I've read online claims passthrough and vhdx should be very similar performance, as well as host and VM performance.  There are no other VM's on the host.

Has anyone come across this before? 

Advise on MPIO is required

VM Connect takes long time

0
0

Hello,

I have a new cluster using 2012 R2 and have the problem that if I want to connect to a VM from the Hyper-V Manager (or Failover Cluster) the connection takes about 10 seconds or sometime even longer (20 seconds).

Does someone have any idea why this could be happening? Currently the servers are running in an isolated environment without internet connection, there are 2 DCs (2012 R2) with DNS which have been newly deployed just for this environment.

Any idea how to make the connection to the VMs faster? Could the lack of internet cause this problem?

Regards

Move Virtual Machine Storage on a Clustered vm = Disk Read Error?

0
0

Having an issue when moving Virtual Machine Storage on a Clustered vm is breaking (corrupting?) the vhdx.

Setup:

2-node Hyper-V Server 2012 (the free one) Cluster connected to an EqualLogic PS6100E using a CSV.  (2) Teamed (Hyper-V) LAN nics and (3) iSCSI MPIO nics each.

Starting Location:

  • VM named "vv-2012" is built from an ISO and running on a server in the node - NOT added to Failover Cluster Manager as a role yet.
  • Disk lives at "C:\ClusterStorage\volume1\vv-2012\Virtual Hard Disks\vv-2012.vhdx"
  • VM lives at ""C:\ClusterStorage\volume1\vv-2012\Virtual Machines\xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.xml"
  • Machine is Running at Login Screen directly after setting the local Administrator password
  • Running current Integration Services

Test 1 - From Starting Location - Move VM Storage using Hyper-V Manager - Move just the vhdx one folder up ("C:\ClusterStorage\volume1\vv-2012\vv-2012.vhdx")

  • SUCCESS - vhdx moved and machine still running

Test 2 - From Starting Location - Import into Failover Cluster Manager - Move VM Storage using Failover Cluster Manager - Move just the vhdx one folder up ("C:\ClusterStorage\volume1\vv-2012\vv-2012.vhdx")

  • FAILED - Disk Read error in the running VM as soon as the move starts (see below image)

Test 3 - From Starting Location - Import into Failover Cluster Manager -SHUT DOWN RUNNING VM - Move VM Storage using Failover Cluster Manager - Move just the vhdx one folder up ("C:\ClusterStorage\volume1\vv-2012\vv-2012.vhdx")

  • SUCCESS - Started VM - no errors

Working on the, now, broken vhdx:

- Searching technet (and the Internet - Google/Bing) returns almost exclusively P2V conversions using disk2vhd.exe from Sysinternals.  That is NOT the case here - reading these posts talks about partitions not being imported (boot partition) or incorrect IDE/SCSI settings on imported vhd's.

- Attaching the vhdx to another vm (or my local machine using Disk Management) and running chkdsk returns "Corrupt master file table. Windows will attempt to recover master file table from disk."  "Windows cannot recover master file table.  CHKDSK aborted." (also tried with /F even though screenshot does not show that - same result) - I see the 2 partitions (boot and system) but cannot browse them - marked as RAW

- Running TestDisk returns invalid MFT (I think, not an expert on this program).

Summary:

- Moving vm vhdx's that are turned off either through Hyper-V Manager or Failover Cluster Managerwork fine

- Moving vm vhdx's that are running through Hyper-V Managerwork fine

- Moving vm vhdx's that are running through Failover Cluster Managerbreaks (corrupts?) the vhdx.

So my questions are 3 fold:

  1. Can anyone else reproduce this?
  2. Is it a Hyper-V / Cluster bug?
  3. Can I recover the vhdx?

Wasn't sure if I should post here or Cluster forum?  Both?

Fabric Resource & Virtual Switch help

0

Hi,

Apologies if this is a silly question.  Basically we have a couple of Hypervisors HP Blade.  The first Blade has a virtual network teamed NICs which give the guests network access.

When I provision an additional blade, I have to create another virtual switch rather than use the switch previously created.  Am I correct in understanding that there needs to be one overall switch added in to each blade rather multiple VSwitches for each blade?  And if so how would I go about creating it?

Currently we have a VSwitch on blade 1. But looking Blade 2 nothing is available so I have to create a second.  If we ever fail the clients presumably the guests loose connectivity because it's set up incorrectly?  How do I go about creating it so that it's done with the bigger picture in mind?  Also how would I do this without affecting the current guests on blade 1?

Any advice would be appreciated and apologies if this question is somewhat convoluted!
