Loss of CSV Connectivity in Failover Cluster

I recently had an issue where one of my Hyper-V nodes (Let's call it Node D) in a failover cluster would fail it's health check and consistently reboot every 30-40 min. Logs stated that the problems were with the netft driver, which after led me to DCOM errors with the vmms service. I tried to re-register the service, but that only caused the service to disappear completely. I was left with having to uninstall and re-install the Hyper-V role on the node. That went without apparent issue, but now whenever I boot Node D (and do not disable all but the management NIC), all the other nodes (Nodes A-E) in my cluster lose connectivity to the CSV shared storage and all my virtual machines cannot be reached! When I shut down the Node D, all connectivity returns.

I've disabled the NICs (except management), and even removed the iSCSI connections to the storage on Node D. It can't talk to the storage. What is it on Node D that is causing my other nodes to lose connectivity? I think it might be Failover Clustering, but what is Node D doing to be taking the storage away from the other nodes?

≪ Previous: Loss of CSV Connectivity in Failover Cluster

Hello all,

I am attempting to configure a specific setup, and was wishing to get some initial inputs on any potential barriers in my intended setup before I make any large changes.

Current Setup:

One Windows 8.1 desktop, used by myself for work + personal hybrid use, and another user for personal use (AMD FX-8350, 16 GB Ram).

Changes:

I am looking to setup Hyper-V with a VM for Windows Server 2012 Standard, containing Exchange Server 2013 Standard, for learning purposes (work-related intent) and for light use (personal-related intent). I have considered making this the host OS, but then there would be issues in maintaining the benefits of the above current setup for personal use.

Questions:

Will there be any issues in remotely connecting to this VM to utilize the Exchange Server?
If User2 is logged in physically, will that block RDP into the VM? I have read that you cannot have concurrent logins on Windows 8.1, does this still apply if you have a VM running under User1's account which may accept RDP?
Any other concerns with my desired setup?

Thank you for your time and expertise,

Jason

Never had this problem before, but today am installing some new windows 2008 R2 Standard VM's and I have no mouse control.

says mouse not captured in remote desktop session.

obviously I cannot install integration services as there is no OS installed yet.

I can connect to any exisitng VM, and mouse control works fine, the issue is only occurring when trying to install window son to a new VM.
I presume integration services is supposed to be loaded by the installer.

Normally I only install Web edition and never had this issue before.

I belong to a local large IT Pro group and Microsoft has asked us to download and try Hyper-V Server 2012 (also R2) and provide feedback. We have many members who have never used Server 2012 much less Hyper-V. Is there some free training, tutorial, exercise, or pill that can be taken to quickly get up to speed? I know we are not going to become administrators in a week but we need to at least know how to do a few basic things with it.

One of the guys copied the ISO to a USB flash drive, put it on a necklace, and slept with it last night. He reports that the flash drive still works but he does not know anymore about it than he did yesterday. So we know that doesn't work.

I have the need to create base boxes using Veewee such that I can then create and destroy VMs on demand using Vagrant, this works really nicely with VirtualBox but is proving to be a real PITA with HyperV.

The biggest problem I've encountered is the fact that the VMMS service cannot access any network shares on my network, which leaves me with no other option than to perform less than clean copying and mounting of ISO images on the hyperv host.

What are exactly the settings that are required to run VMMS using a domain account, and to avoid the error below:

≪ Previous: how to download Hyper-V Integration Services for window server 2012

I am getting a "Failed while adding Virtual Ethernet switch connections" when trying to establish a virtual switch over a WiFi connection which I had previously used. The details say "Ethernet port {GUID} bind failed. The requested resource is in use. (0x800700AA). "

Uninstalling and reinstalling the WiFi adapter changed the value of the GUID but still same error message.

There is no vEthernet adapter showing in the adapter properties window. My assumption is that the adapter is hidden from view in the window and / or there is some binding stored in some xml files or registry keys someplace linked to the Virtual Switch that needs to be manually cleaned. However, I have not yet found where these are.

Has anyone figured out a good way to resolve this issue?

Lost Remote Desktop Connections to the .vhd after losing the Virtual Machine. How do I reconfigure the VPN settings so that the workstations can connect

August 23, 2013, 10:26 pm

≫ Next: Hyper-V SAN Configuration

≪ Previous: 2008 R2 VM cannot browse the web

Recently we have been having problems with the Hyper V Virtual Machine.

We have a Virtual Machine, running Server 2008 R2, named Terminal the has a .vhd that houses a program named ProCent and it's data. The server itself runs Microsoft SBS as it's primary OS.

The Virtual Machine disappeared and couldn't be found in the usual file, nor could it be found doing a scan of the C drive. The Virtual Hard Disk was still there with all the data present. We also had a good tree of snapshots, and backup daily, so no data has been lost.

I created a new Virtual Machine and renamed it Terminal and attached the .vhd to it.

All of our workstations connect through TCP to the Virtual machine through a VPN named Virtual Network 1. The gateway to Terminal is 192.168.3.254.

I can still get to ProCent through connecting to Terminal on the server, and the environment is intact. However none of the workstations are able to correct using the Remote Desktop as before this crash happened.

Any recommendations?

≪ Previous: Lost Remote Desktop Connections to the .vhd after losing the Virtual Machine. How do I reconfigure the VPN settings so that the workstations can connect

I am in the process of planning the virtualization of my infrastructure (better late than never).

My servers consist of

Domain Controllers
Exchange Servers
SQL Servers
File Servers
Anti-Virus Servers
SharePoint Servers

The new environment will consist of a 3 node Hyper-V cluster connected to an iSCSI Dell SAN.

My question is about how to configure the SAN in terms of Best Practices.

Should I split the SAN into equal LUNs e.g. 10 x 200GB and present them all from the onset. Or should I only create LUNs for the storage I need now e.g. 5 x 200GB, and leave the remainder capacity unallocated?

Should I create different RAID types and store the VHDs according to requirements e.g.

LUN 1 : RAID 1 : store File Server OS VHD

LUN 2 : RAID 5 : stores File Server DATA VHD

or should a VMs VHDs all be stored on the same LUN and/or same RAID type (RAID 10 perhaps?)

Is it beneficial to create numerous smaller LUNs and present several CSVs to the Hyper-V hosts or should I create a single larger LUN and present one CSV for all virtual machines?

I plan to leave the virtual Domain Controller on local storage as my understanding is to not cluster it.

Any other Best Practice tips for Hyper-V SAN configuration.

We have a windows server 2012 as a hyper v host and 2 VM S SBS 2011 and windows 7 VM

Since this Tuesday the CPU usage is a constant 100% on both VMs and since backups were failing due to high cpu usage rebooted the SBS 2011 server. But even after a reboot/shutdown SBS is at a constant 100% usage

We disabled all non MS services, disabled Exchange, SQL and memory hungry services but the CPU usage is at a 100%.The time it goes down is when we stop all MS /NON MSservices except bare minimal services which needs to run the SBS properly

Even with this the moment we open up a MMC console , open up an application on the server the cpu goes to 10% and remains for a long time and then goes down again

But with all SBS services running it never happens and stays at a 100% even after acouple of hours

Hyper V integration services are up-to-date

Any advice is greatly appreciated.

Thanks

Unable to create virtual hard disks on drives other than C:

≪ Previous: All Hyper V VM s are using 100% CPU

I've finally got Hyper-V set up on a core installation of Windows Server 2012. The machine is in a domain and I'm able to remotely manage it using RSAT on a Windows 7 box. I'm a member of Domain Admins.

When I try to create a new machine or add a disk to an exiting machine, it fails, but only when trying to make the disk image live on a drive other than C:. C: is ~900 GB, D: is 2 TB, and E: is 2 TB. Both D: and E: fail.

Permissions look like this:

C:\tmp NT AUTHORITY\SYSTEM:(I)(OI)(CI)(F)
       BUILTIN\Administrators:(I)(OI)(CI)(F)
       BUILTIN\Users:(I)(OI)(CI)(RX)
       BUILTIN\Users:(I)(CI)(AD)
       BUILTIN\Users:(I)(CI)(WD)
       CREATOR OWNER:(I)(OI)(CI)(IO)(F)

D: BUILTIN\Administrators:(OI)(CI)(F)
   NT AUTHORITY\SYSTEM:(OI)(CI)(F)
   CREATOR OWNER:(OI)(CI)(IO)(F)
   BUILTIN\Users:(OI)(CI)(RX)
   BUILTIN\Users:(CI)(AD)
   BUILTIN\Users:(CI)(IO)(WD)

So I don't think it's a permissions issue. I can read and write to D: and E: using anything other than Hyper-V.

I receive a very generic error message from Hyper-V when the problem occurs:

"The server encountered an error trying to create the virtual hard disk."

"Creating the disk at location 'D:\disk\New Virtual Hard Disk.vhd' failed."

There is no Details button to expand for more information.

Event logs yield nothing useful.

Any thoughts as to what's causing the problem?

I am trying to install a CentOS guest on HyperV using a kickstart file hosted on a temporary webserver on my workstation, however I cannot get the CentOS installation process to connect to my workstation.

I've verified that this works if I use a local hyper-visor like VirtualBox on my workstation.

I've also run through the installation by hand and the problem seems to be the fact that no eth0 device is present in the CentOS after installation. I've searched the forums here on why that might be and also dug through some CentOS FAQ but haven't found any answer that would help me get around the no eth0 present at boot time problem.

Hyper-V 2012 Trunk to a vmware administrator

August 26, 2013, 1:39 am

≫ Next: Converting VMware files to VHD

≪ Previous: How to Backup Hyper V SQL 2008 server over remote location

I'm setting up my first Hyper-V server based on Hyper-V 2012 on a server with 2 10gbit (which I team). In vmware I would create a virtual switch with the two physical nics and add a number of vlans to the virtual switch (and by that creating a trunk). And more important setting the network on a vm, I select one of the vlans I've created.

In Hyper-V the virtual switch part looks the same, but the vlan and vm part is very different as far as I can tell. I can add several vNICs using powershell, but when I want to select a vlan in a vm I only see the virtual switch or I can manually type a vlan ID (which is too error-prone and management wise too time-consuming).

The only doable thing I've seen so far is to create a virtual interface for each vlan (I need about 32 vlans), create a vswitch for each virtual interface, and assign the right vswitch to a vm.

Are there a better way to do it without VMM?

Cheers,

Anders

Converting VMware files to VHD

≪ Previous: Hyper-V 2012 Trunk to a vmware administrator

Hi.

So scenario is:

2 separate domains, no domain trusts and a very slow internet connection on 1 end.

I need to mount one VMWare VM from the source domain in Hyper-V in the destination domain, to transfer between the two, the VM or VM files needs to be transported on an external USB disk via mail.

I only have Hyper-V (2008 R2 - 2012) available in the destination network and only VMWare ESXi 5.1 available on the source network.
The process of getting the VM or VM files should not alter the original VM or VM files in any way.

I gather System Center Virtual Machine Manager and 5nineEasyConverter both requires me to have VMWare and Hyper-V on the same network which I dont. Or am I wrong?

The tool StarWindConverter works on a file level, but I am failing to copy the *.vmdk files to a Windows drive using the PowerCLI from VMWare (The remote server returned an error: (500) Internal Server error). So I cant run that tool unless I manage to copy the files from the VMWare datastore which I'm stuck on.

I'm looking at MS Virtual Machine Converter (MVMC) but cant gather if this tool will leave the original VM intact or not. Also dont think it works for ESXi 5.1.

The VMDK2VHD isnt going to work unless I manage to copy the vmdk file from the VMware store and seems StarWindConverter works better for most people anyway.

Seems VConverter was discontinued by Dell/Quest.

I'm running out of ideas! I realize this isn't a Microsoft question per say, but I am hoping some forum users might have had similiar needs and found a way to achieve the objective.

Thank you.
