Live migration to HA failed leaving VHD on local storage and VM in cluster = Unsupported Cluster Configuration

0
0

Hi all

Fun one here, I've been moving non-HA VMs to a HA and everything has been working perfectly until now.  All this is being performed on Hyper-V 2012R2, Windows Server 2012R2 and VMM 2012R2.

For some reason on the VMs failed the migration with an error 10608 "Cannot create or update a highly available virtual machine because Virtual Machine Manager could not locate or access Drive:\Folder"  The odd thing is the drive\folder is a local storage one and I selected a CSV in the migration wizard.

The net result is that the VM is half configured into the cluster but the VHD is still on local storage.  Hence the "unsupported cluster configuration" error.

The question is how do I roll back? I either need to get the VM out of the cluster and back into a non-HA state or move the VHD onto the CSV.  Not sure if the latter is really a option.

I've foolishly clicked "Ignore" on the repair so now I can't use the "undo" option (brain fade moment on my part).

Any help gratefully received as I'm a bit stuck with this.

Thanks

Rob


Hyper-V won't install on x64 Windows 8.1 Pro

0
0

I can't seem to get Hyper-V installed.

I am running Windows 8.1 Pro 64

Steps to reproduce:

1. Add/Remove Features

2. Add Hyper-V, and all subsets

3. Click OK.

4. Click Restart when prompted.

5. Computer will reboot and then work on configuring features.  At 91% the computer will stop and display the error message "Unable to add feature..." and then roll back entirely.

Does anyone have any ideas as to the cause and fix?

Thanks,

Daniel

Any way to tell WHEN and WHO created a VM?

0
0

Howdy,

I'm just wondering if there's a Powershell command or somewhere in the VM properties that might show me which ID created a given VM and when it was created.  Anyone know if that's something easy to find?

If it's a script I can run against a bunch of VMs at once, that'd be great.  Or if I have to check the manually, that work too but wouldn't be as ideal.

Thanks!

Expand Dynamically Expanding Virtual HD Space

0
0

Hi Server Expert,

I have a Server 2012 Hyper V server that being installed with few VMs. Those VM are using dynamically Expanding virtual HDD.

Take an example from one of the server below:

A VM called "Finance Server". this server virtual HDD has been configured with dynamically expanding virtual hdd. On the hyper v server, we created 500GB partition and this partition is being used to store the virtual hdd of the "Finance Server". I created 3 dynamically expanding VHD as I would like to have 3 partitions on the Finance Server. The three dynamically expanding VHDs are A.vhdx,B.vhdx, and c.vhdx. A.vhdx is 50GB, B.vhdx is 100GB, and C.vhdx is 150GB. each of the dynamic VHD will correspond to the partition in the "Finance Server". So, C partition is using A.vhdx, D partition is using B.vhdx, and E partition is using C.vhdx.

The Problem Encounter:

D partition is out of disk space. in this case, how am I going to expand it? Should I expand the space on the Hyper V server? currently the "Finance Server" is using 500GB of the HDD space. if we increase disk space by 200GB in the Hyper V Server, after extend the 500GB to 700GB, how am I going to use the space that just being increased into the "Finance Server"'s D drive? does it mean that by increasing the Hyper V disk space of 500GB to 700GB, the Finance server will be able to automatically consume the new space of 200GB or I need to login to Finance Server and activate it?

Now, if the finance VM is able to consume the 200GB free space from the server, how should I allocate it to the partition D inside the  finance server? does it mean that by increasing the size of D drive by using the new space of 200GB will solve the issue? or I still need to expand the size of dynamic VHD? as I know dynamic VHD is not able to expand as it will always grow right?

Thanks

Identifying which Lun my Cluster disk is on.

0
0

I have inherited a Hyper V environment that was set up by someone who was apparently in love with the next button. All of the csv have the default name of Cluster Disk 1, Cluster Disk 2 and so on, and the folder names in c:\cluster storage are all Volume1, Volume2 and so on. There are six disks in total 4 of which are 2TBs, making it impossible to determine which lun it exists on on the Equalogic san based on size. 

Is there anywhere in failover cluster manager, or anywhere else, that will tell me which csv is on which lun. The luns are all named differently in SAN HQ.

I have looked in diskpart but the LUN ID entry on detil disk all say 0. And the disk IDs don't correlate to the iscsi identifier.

Any help is appreciated

Enable replication fails with certificate CN error

0
0

I am having an odd issue with enabling replication between my Hyper-V hosts. We don't have a central CA so I am using a TechNet blog post "Hyper V Replica Certificate Based Authentication Makecert" (Sorry, my account has not been verified so I can't post links)

These steps have worked 100% on 4 of my Hyper-V hosts but I have 1 host that keeps giving me the following error:

"Hyper-V failed to enable replication.

Hyper-V failed to enable replication for virtual machine 'vsprdrec12': The certificate's CN name does not match the passed value. (0x800B070F).

The Replica server's name  for Hyper-V does not match the received certificate's subject common name (CN) or subject alternative name (DNS Name): The certificate's CN name does not match the passed value (0x800B010F)."

(Sorry again, account hasn't been verified so no screen shot of the error.)

The primary and the replica servers are set up exactly like my other primary and replica servers, but only this one gives me the error.  Anyone have any suggestions on a remedy of resources?

Thank you all in advance.

blue screen error after converting physical to virtual server using disk2vhd

I have used the sysinternals disk2vhd to create the c: drive from a Dell server. I was able to create a virtual server and boot but had licensing issues. After a support call and doing a repair install to change licensing I am now getting a: "a process or thread crucial to system operation has unexpectedly exited or been terminated" after the virtual machine boots and I log on. I tried to get the integration services installed but the server wouldn't stay running long enough.

Any suggestions for resolution would be appreciated.

removal of ata_piix generate crash for VM running on HyperV 2012 R2

Hi All,

I have a below use case:

1. created a VM with 1 vhd and 1 VHDX disk on HyperV2012 R2 hypervisor.

2. created 1 bootable iso which contains vmlinuz & initrd file from Oracle enterprise linux 6.4 media.

3. mount created media on VM and booted this VM using CD boot option.

4. when machine boots ata_piix controller gets loaded at initrd stage. but while unloading the ata_piix, it crashes and generate the call trace.

5. when there is only single disk attached to VM loading and unloading of ata_piix controller happens successfully, without any problem.(note: disks are running on IDE controller).

6. one more strange thing is: when I add one more virtual processor i.e. if two virtuall processors are present in VM then ata_piix gets uunloaded successfully, without any crash. but if single processor is there then if one disk is attached. ata_piix gets unloaded successfully but if more than 1 disk is attached to VM, unloading of ata_piix generate crash.

need your help to resolve this issue. Please look into it and do let me know if you need any further info to resolve the same.

Thanks,

indus.

Copying a Windows Server 2012 R2 standard install

0

Dear Experts,

We have done a basic installation of a Windows Server 2012 R2 will all updates. Windows has not be activated yet. We need a second server - before we do a second installation we thought it would be easier to simply copy the virtual machine. Is this possible? I know that with older Windows Systems and without virtualisation, one had to do a sysprep otherwise one could have problems with the SID or HAL.

Thanks for your help.

Hi, 

I have a problem, with configuring a Virtual Network Adapter on SC VMM. 

I created a logical switch with two physical network adapter (team) and add a virtual network adapter to the logical switch. After that a virtual network adapter will be created on the hyper-v host, but with the status "domain.local (unauthenticated). With another hyper-v host it work without problems. 

I tried to remove and recreate all that stuff but without success. 

Do someone know that problem? Or can help to find a solution? 

Thank you for the help.

Unable to Join Hyper V Virtual Machines to Domain

Hello Team,

I installed Hyper on Windows 2012 R2 server and loaded Virtual machines. All looks good. I want to join my VM's and the Guest machine to the Domain. I set the Internal Lan on the Guest OS to the Domain Controller running DNS. I am able to ping the server and I am able to join the Guest OS to the domain.

Now I want to join the Virtual machines to the same domain , but how to configure the NIC on the VM , so that it can ping the Domain Controller ? Virtual Switch Manager is configured with External network and also enabled "Allow management operating system to share this network adapter".

So I am little lost here to how to make the Virtual machines talk to the Domain Controller ? What would be the NIC setting on the Virtual machine ?

Any help would be appreciated!!

Can not export VM from Hyper-V host to the network share folder?!

0

Hi there,

I’m trying to export VM from our ‘old’ Hyper-V 2008 R2 server onto the ‘new’ 2012 one. Both Hyper-V hosts are in the same Active Directory domain. Since core editions don't have GUI I’m using Hyper-V Manager console on my workstation (Client1).

VM Export

As soon as I click ‘export’ button I have windows popup immediately with the error message: “Failed to create export directory… (0x80070005)”?!

export error

I have setup appropriate share and NTFS permission as recommended by this post: “Error 0x80070005 when exporting Hyper-V VMs over the Network” (http://support.microsoft.com/kb/2008849). I even gave Client1 the same permission but still have the same error message?! From Client1 or Server1 I can connect to the \\Server65\Export$ folder, can copy/delete/create folders and files without any problems. What I have missed?! Please help, thanks.

Windows 2012R2 Domain Controllers running as HA W2012r2 Clustered VM

0

I have seen a lot of articles talking about not running DCs in an HA Clustered configuration for many justified reasons.  The articles refer to only having a limited amount of Domain Controllers in the environment.  Suggestions were to have at least one (FSMO Roles) as a physical.  There was mention to have them on Clustered nodes but not in the cluster using storage assigned to the Node that is not shared.  If the requirement for having a physical DC is met and a few of the DCs as a VM in a non clustered config is met, is it best practice to run the rest of them in a HA Clustered environment including RO DCs?

Thanks for any input provided

Hyper-v VM going to saved state

I have a server 2008 r2 system with Hyper-V running a windows server 2008 standard VM.  The VM was converted from a physical system.  The system has been running without issue until this week.  The VM is now dropping to "Save" state and then starting back up.  This is causing a great deal of frustration for my client.  I have added the Hyper-V folders to the antivirus exclusion list.
