Hello,

I have got a strange problem here and I don't know how to approach.

Evenrytime I reboot a virtual machine with a taged VLAN it brings the cluster node, on wich the VM is running, down.
Doing the same with the same VM in the native VLAN doesn't do any harm.
Shutting down the VM and starting it up again doesn't crash the node - it only happens when I reboot the VM.

The problem is 99%-100% reproducable. I have tested it against Win7, Win8, Srv 2008R2, Srv 2012 as a guest OS.

The problem seems to be related to july pathday. I started some testing with update/compliance baselines in VMM. At least that's when I noticed the issue.

My environment - It's a LAB environment:

• 4 Node Windows Server 2012 Hyper-V Cluster
• Cluster uses NIC Teaming for LAN (4x 1GBE as a Team for Management, CSV, LM, VM) and MPIO for SAN (2x 1GBE)
• SCVMM 2012 SP1 to manage my cluster
• Cluster validation tests passes without any warning that I can associate with the behavior.
• LACP status of the teams is ok.

When I check the Event Log on the particular cluster node, I see BugCheck Event 1001 with Stop Error 0x000000d1

Any input or help would be appreciated - I don't want to start from stratch with my setup.

We have a 4-node cluster running Windows Server 2008 R2 and VMM 2008 R2.

Users are unable to create any virtual machines via the self service portal.  The error returned is:

Unable to create the virtual machine because no suitable host for this virtual machine was found.

There are no volumes available for placement. For clustered hosts, all shared storage is currently in use or not available. In addition, some of the volumes may be marked as unavailable for placement.

Except I am unable to identify why this is the case.  Creating VMs via the Administrator Console works fine.

There are 5 CSVs configured.  And VMM sees them defined on the cluster properties:

Additionally, when I go to the properties for an individual host and look at the storage, I verified that each CSV is marked as "Available for Placement"

The one strange thing I noticed, is over on the "Placement" tab - there are no paths in that list.  Not only are there no paths, but the "Add" button is disabled, so I cannot add them.

This has worked fine, but I'm guessing we changed something in the configuration that broke this.  Unfortunately, everything configuration-wise seems as expected.

Any ideas?

Hi,

I have two questions:

1) is there any way to not(!) make a VM HA when deploying it using SCVMM on Windows 2012 Cluster CSV? This is a requirement for us but so far I didn't find a way around it. When I use a non-HA VM template I cannot deploy the VM on the CSV using SCVMM.

Using an SMB Share is not an option. I would never get the agreement for that - well maybe in five years or so...

2) At the same time when I move a VM from a stand alone Win 2012 Hyper-V Host to a Cluster hyper-V host on the CSV this VM automatically becomes a HA VM. That means I cannot move it back to a stand alone Host. Any ideas how to prevent that?

Thanks.

I have two 2012 hosts that failed and I removed them from the cluster but I am cannot remove them from VMM 2012. They have a status of pending and when I try to delete them I get prompted for my credentials but after I hit ok nothing happens.

I noticed today that Dynamic Optimization stopped functioning for one of my two clusters in VMM.  Both Clusters use the same settings from a parent folder and DO still works in the other cluster.  I have not modified the default thresholds for available resources.  In my problem cluster I have every VM running on one host leaving the second host completely empty.  Running DO on the cluster still tells me that there are no possible optimizations.  

There isn't an issue with the host not being able to run the VM's, I am able to manually migrate from one to the other.  I have also placed each of the hosts in maintenance mode (one at a time) letting the VM's migrate on their own.  No other issues appear to be present in the cluster.

The VM settings have both hosts checked as available hosts and they have one specific host checked as the preferred host.  I want to use these settings to be able to move the VM's back to the "Home" host if you will.  This works beautifully on my other cluster and used to work on this cluster until this morning.  

The only thing done this morning to the cluster was a quick and dirty HA test by unplugging the NIC's of the first host and verify that the VM powered up on the second host.  After that was verified the first host was reconnected.  VMM does not report any errors on the host.  

Dear Expert,

We are facing problem for production hyper-v 2012 cluster virtual network.

We have hyper-v 2012 2 node cluster. On physical server we have 2 NICs. We did the teaming of 2 NICs using Broadcom Teaming Utility. We are using LACP as teaming Policy we has created Hyper-v Virtual Switch on top of TEAM interface.

We have configured trunk on switch for passing 4 VLANS

We have created 4 virtual NICs as below and tag the VLANs to VNICs. All the VMs are configured with VLAN ID 1

It was working fine.

Today we have faced issue with VMProduction virtual NIC and all the virtual machines. All of sudden all VMProduction Virtual NIC and all virtual Machines lost network connectively on both node but same time other virtual NICs are working fine. After 3 hours automatically network connectivity restored without doing any changes on server and switch.

Please help me to understand how to troubleshoot this issue. I am very confused. We have checked on switch everything is fine.

Hi There,

I'm currently working with a Hyper-V and Scale Out File Server system, and I'm having trouble getting my head around how exactly the Hyper-V Hosts communicate with the File Servers. Our current setup is as follows: We have 3 File Servers set up in a Fail-over cluster with the SOFS role enabled. Currently we are using a DNS round robin system on our DNS servers to select which of the 3 file servers a server connects to, this leads to the situation where if one of the File Servers fails the servers that were pointed to it lose connectivity and simply don't fail over to anything.

This setup seems obviously incorrect, but I'm not sure exactly how to fix it. It seems as if the scale out cluster itself should have an IP address I can point at? I'm sure that I'm missing something here.

Any help would be greatly appreciated.

Is it possible to have a 2Node Hyper-V Cluster where each Host has 8GB RAM totalling 16GB in the cluster and then have 2 VMs 1 with 12GB Memory and the other with 2GB totalling only 14GB RAM?

For the sake of this discussion, HA is no needed. I just want to know if a VM can use more RAM than what is available on a single Host. The question is more about Share memory among cluster members...

Hello please someone help me,, I have paid Microsoft for 1 year support and can get no help,,I was hit by a virus and it has attached it self to where it keeps coming back and taking over everything - changing all  my settings  it uses a user name of s-1-5-21-1330211563-1659007443-1864422605. microsoft support deleted only the original key,,never seen it was attached to so much and again it has came back  and this user id is now on 13 items.. can any one time me what is happening ..I have screen shot but unable to save as jpeg

thank you Robie

Good Day,

We have a simple two node cluster running on Windows 2008R2 Datacenter the nodes, these  hosts are called VM1 and VM2.

 Our VM are running Windows 2008R2 Standard and just finished upgrading them to SP1. 

We live migrated all the VM to VM2 and updated VM1 to SP1 then applied any windows updates.  We had some issues and lost the network setting after applying driver updates. After a day we were able to recover and get everything back online.

When we try a live migration from VM2 (Still RTM) to VM1 the live migration fails we are able to do a fast migration.  Which we did on a test VM server.  When we try to live migrate back to VM2 it fails again. 

My first question is this

Is this because SP1 is not installed on VM2?  None of the VM have been updated with the latest version of integrated services ether as I wanted to update VM2 to SP1 first.   I can give more info later on the errors in my next post. 

Thanks

Hi,

I have implemented 2 physical servers running Windows Server 2008 R2 EE and with the Failover Cluster feature I made a cluster in order to make Virtual Machines highly available.

Now, I am wondering what kind of servers may I put in that infrastracture, because Domain Controllers have their own HA mechanism, the same for Exchange and SQL. I know that I can put a file server, a terminal server, but....

May I put a DC, Exchange, or SQL server in a HA VM? and what else?

thanks in advance.

Hi all,

I need some clarification on cloud building with scvmm with a custom made portal.

Creating the cloud:

1. Create the infrastructure with SCVMM
2. manage the infrastructure with SCVMM
3. use SPF for creating the custom self service portal
4. or use Azure pack for SCVMM as the end portal

My question is are the  steps correct?

More specifically, at what point do we connect with a 3rd based app and provision the SCVMM managed cloud?

Do we only need SCVMM and then make SCVMM powershell calls from an "provisioning service", or do we need to go to SPF and them make the calls, or maybe install Azure pack? Where is the API located (on what component) that we can use?

Thanks

I had customer with both Windows 2012 Hyper-v  and VMware , they have created VM's on both ( Windows 2012 , Windows 2008 , ), those Vm's were part of Cluster ( Some of VM on Hyper-v Cluster and other was VMware Cluster), all VM was 150 GB File and OS was installed for 80 GB Partition,  they just wanted to reduce all VM's File( Hyper-v and VMware ) size to 80 GB only. From the VMware, it was very easy and just rig click and do resize,

Sorry to say the Microsoft (even they had SCVMM 2012 SP1), this was not so easy, it's made me embarrassing about hyper-v.  This is how I resize and if anyone knows better than this pls let me know. Since this is basic requirement, I don't know why still Microsoft can't do this (at least if it's available on window 2012 R2, we can justify for customer)

1: use VHDResizer tool

2: move VM to Standard Alone Server(move from cluster to standard alone ), convert fix disk to dynamic(lucky it's available now ), from hyper-v Settings(even can't do it from SCVMM settings )  compact the disk .

Anyone knows how to resize Fix disk on Cluster VM very easy.

When i try to move a VM to a clustered volume that is using a mount point, I get an error that is path is invalid.  I verified i could still acess the path on the host without issue.

How do i move a VM to a volume using a mount point in a cluster?

Hi 

Im looking into new features of Server 2012 R2 and SCVMM 2012 R2 are offering and got really confused. 

I'm trying to build file servers on Guest clusters , and I have Dell equalogic Storage

Can anyone suggest which route is better Virtual SAN, VHDX or Pass Thru disk ? 

Also if you have some  tabular comparison then please feel free to post .

Thanks

Hi guys,

I have a two-node hyper-v failover cluster namely 'failover2308' . After I finished my testing, I completely destroyed the cluster and hyper-v hosts. I found that all the virtual machines and one  hyper-v host are still in scvmm. Luckily i was able to delete the VMs by following the passage below

http://blogs.technet.com/b/chrad/archive/2010/06/23/scvmm-failed-objects-are-not-manageable-nor-can-i-delete-them-please-help.aspx

However, I am not able to delete hyper-v host. When I delete it, it stucks in the loading state for many days even if I restart VMM service (see the picture below). Please help me to delete the cluster node or cluster.

----------I tried the command below to delete host------------

get-vmhost <hostName> | remove-vmhost -force

But get error showing something like " cannot remove the host xxx because it is part of the cluster xxx" (error id: 13810)

---------I also tried the below command to delete cluster-----

$Credential = Get-Credential

Get-VMMServer -ComputerName "<netbios name of scvmm server>"

Get-VMHostCluster | Remove-VMHostCluster -Force

But get error showing something like "Unable to perform the job because one or more of the selected objects are locked by another job." (error id: 2606)

Any idea is very much appreciated!

Hi. I have a HA file share that serves as library share for VMM 2012 SP1. It seems to be working fine, but on my management server where I have the VMM console installed and on the node that is the owner of the fileshare cluster resource (no errors on the non-owning node), eventlog is being spammed by the following events:

EventID:6, Source: SMBWitnessClient: "Witness Client failed to find a Witness Server for NetName \\havmmlib with error (Element not found.). Retrying in (60) seconds."

EventID:6, Source: SMBWitnessClient: "Witness Client failed to find a Witness Server for NetName \\havmmlib.domain.local with error (Element not found.). Retrying in (60) seconds."

havmmlib is the clustered DNN. Two node cluster with a disk as witness.

I've tried searching on the Internet for errors related to SMBWitnessClient, but there's not much out there.

Any ideas?

I am trying to creat a Hyper-V cluster using SCVMM, but I cannot get passed the validation. Everytime it tries to test the cluster it fails with the following error at 95%:

Two disks have been found on node adl-hpv-001-d.domain.local with duplicate disk
signatures. The disks involved are physical disk 0 and physical disk 1. There
may be a Multipath I/O (MPIO) problem such as the software is not installed or
is not working properly. If MPIO is not involved, or MPIO has been verified as
working, you must either mask one of these disks off at this node, or run
validation and specify a disk list that includes only one of these disks, for
example by using the Test-Cluster cmdlet in Windows PowerShell.

The 2 nodes are running Hyper-V server 2012

MPIO is installed and working but the report shows only

The storage is presented by multiple Fibre paths as shown below, I've tried re-creating the LUNs but nothing seems to work. I am hoping to get this running with the wview to migrate from VMware, but at this stage it's hard to prove my case. any hlep here would be appreciated

Thanks

Below are the error when I try to setup a cluster in VMM 2012 R2

I have 3 hyper-v added in VMM, iSCSI target using Starwind.

I have added the iSCSI SAN server as my storage device in VMM, classified the pool, create logical units, and allocate capacity (2 pools and 3 logical units) to the host group (consists of 3 hyper-v machines)

I have setup iSCSI connection in each hyper-v.  I have got the same error without going to each hyper-v and configure the iscsi initiators to connect to the target.
