Failing VM on 2012 R2 Hyper-V Cluster

0

Hi,

I have a 4 node Hyper-V cluster running Windows Server 2012 R2. I'm having a problem with one VM on the cluster dropping randomly with a 1069 event in Failover Cluster Manager (Cluster resource 'virtual machine <vm name> of type 'virtual machine' in clustered role '<VM name>' failed). I'm aware of at least 3 failures in the last 2 weeks, but can't find a trigger. It did seem (strangely) that it was occurring when running some PowerShell commands on the host (either Get-VM or Measure-VMResourcePool), but the latest drop there was nothing ran against the host.

The VM is running SQL on 2008 R2. I've tried the VM on different hosts (all the same spec) as the first time it happened I wondered if it was faulty memory module, but it has still dropped on that host. It's configured for static RAM with SQL being NUMA aware. The specs fit in a single NUMA node. There are other VMs on the same hosts and on the same storage and they don't seem to have any problem. I've tried removing the VM from the cluster and re-adding it. The hosts that I've tried hosting the VM on are not the owner of the CSV that the VM resides on. I have hardening applied to the hosts, based on CIS guidelines. I believe all recommended cluster and Hyper-V hotfixes are installed.

The event logs on the VM just show the last shutdown as unexpected.

On the host, I've ran a Get-ClusterLog (with -UseLocalTime) and found a few entries that look like they could provide useful info, but I haven't yet found any info on them. The failover cluster dropped the VM about 14:29 in these logs, but I've included some key info from before and after in case it helps:

Hello

I have a power edge r630 with windows server 2012 r2 with hyper-v role to it.

The server has 64GB Ram.

I rebooted the server and when i rebooted and went to start up the VM's it says insufficient resources!

I haven't changed any Hyper-v vm settings

I have tried troubleshooting and the only way i can get the vm's to start is give them 1gb ram each! they all had 8 before

I have 4 vm's 

all running 2012 r2 standard 

PLEASE HELP i am at work and people will be back in work tomorrow morning

I'm studying for my 70-410. I just want to make sure I have this straight. Please help me verify the following statements.

Using the new-VM commandlet you are unable to create a VHD. You can create a VHDX.

Using the new-VM commandlet you are unable to create a dynamic VHDX disk.  

I was wrong about unable to create a dynamic VHDX, its Fixed I can't figure out how to create.

Using the new-VM commandlet you are unable to configure Dynamic memory. 

To create a VHD you would use the new-VHD commandlet

To create a Fixed VHDX you would use the new-VHD commandlet

To to configure Dynamic memory you would use set-VMMemory commandlet

Corrected what I was wrong about, anyone else poke holes in the following statements?




Hyper-V VMs not able to connect to a Domain

0
0

Hello,

To start, I am a student who is doing a school sponsored internship with a local company to gain some experience in the field of IT, as I have a relatively weak background in IT. Currently, my boss is having me set up a series of VMs using Hyper-V (of course) so we can do a simulation of a company with an issue in communication, so I can learn about mediation of disputes and how to resolve VM network problems before we move on to either sending me out in the field or other simulation/ practical experience simulations.

This is where the problem begins.

We are nearing ready to start the simulation, but we can not get the VM's to see each other regularly. We are attempting to get all four (4) VMs onto a single domain, yet three VMs can not connect to the Domain. When we ping one VM from the other, only one can regularly get a response, and more often than not it will be could not reach, about 70% of the pings we use. Occasionally we will get a response, but only between one VM and the server with the Domain Host. Most often the packets time out. Obviously, we can not start the simulation until we can get the VMs onto a domain.

Currently, my boss thinks that the issue is a DNS issue, but I have no idea what that means. I have looked into installing a virtual serial port as I originally thought that was the issue, but due to occasional pings succeeding, I doubt that is the issue. If anyone can explain what a DNS issue is and how to fix it, I would be eternally grateful.

Thanks,

Cameron

2 Hyper-visors home Lab - network

0
0

Hi Guys,

I have two hyper-visors Windows server 2012 r2 with hyper-v. I am using two HP microserver g8, both with 16GB ram, and SSD disks. 

What I am trying to do is to isolate the lab environment from my home network. I have an ADSL wireless router, the cable goes into the HP switch where the home lab is.

Requirements are:

1. Isolate private network 

2. have internet connectivity in the private home lab network

3. ability to access a share or a RDP from my home network to the private home lab network 

4. ability for the VMs on the two hyper-visors to talk to each other

Connect to Hyper-V 2012 R2 standalone from Hyper-V Manager

Hyper-V 2012 R2 standalone is a workgroup machine.

My Win8.1 laptop is a domain-joined machine.

I named my workgroup similar to the domain, then added my laptop domain administrator account to Hyper-V local administrators group.

Configure in my laptop following the step here for adding my Hyper-V 2012 R2 standalone machine as trusted host.

https://technet.microsoft.com/en-us/library/jj647788.aspx

Added both ip address and computer name.  

Now I manage to enter-pssession from my laptop to Hyper-V standalone machine, but I failed to connect to my Hyper-V from Hyper-V Manager (Win8.1 RSAT).  Both using the same credential.

When connect using computer name in Hyper-V Manager, the error message is 

"Cannot connect to the RPC service on computer xxxx.  Make sure your RPC service is running"

When connect using ip address in Hyper-V Manager, the error message is 

"You do not havea the required permission to complete this task.  Contact the administrator of the authorization policy for the computer <ip address>"


VMQ issues with NIC Teaming

0
0

Hi All

Apologies if this is a long one but I thought the more information I can provide the better.

We have recently designed and built a new Hyper-V environment for a client, utilising Windows Server R2 / System Centre 2012 R2 however since putting it into production, we are now seeing problems with Virtual Machine Queues. These manifest themselves as either very high latency inside virtual machines (we’re talking 200 – 400 mSec round trip times), packet loss or complete connectivity loss for VMs. Not all VMs are affected however the problem does manifest itself on all hosts. I am aware of these issues having cropped up in the past with Broadcom NICs.

I'll give you a little bit of background into the problem...

Frist, the environment is based entirely on Dell hardware (Equallogic Storage, PowerConnect Switching and PE R720 VM Hosts). this environment was based on Server 2012 and a decision was taken to bring this up to speed to R2. This was due to a number of quite compelling reasons, mainly surrounding reliability. The core virtualisation infrastructure consists of four VM hosts in a Hyper-V Cluster.

Prior to the redesign, each VM host had 12 NICs installed:

  • Quad port on-board Broadcom 5720 daughter card: Two NICs assigned to a host management team whilst the other two NICs in the same adapter formed a Live Migration / Cluster heartbeat team, to which a VM switch was connected with two vNICs exposed to the management OS. Latest drivers and firmware installed. The Converged Fabric team here was configured in LACP Address Hash (Min Queues mode), each NIC having the same two processor cores assigned. The management team is identically configured.

  • Two additional Intel i350 quad port NICs: 4 NICs teamed for the production VM Switch uplink and 4 for iSCSI MPIO. Latest drivers and firmware. The VM Switch team spans both physical NICs to provide some level of NIC level fault tolerance, whilst the remaining 4 NICs for ISCSI MPIO are also balanced across the two NICs for the same reasons.

The initial driver for upgrading was that we were once again seeing issues with VMQ in the old design with the converged fabric design. The two vNics in the management OS for each of these networks were tagged to specific VLANs (that were obviously accessible to the same designated NICs in each of the VM hosts).

In this setup, a similar issue was being experienced to our present issue. Once again, the Converged Fabric vNICs in the Host OS would on occasion, either lose connectivity or exhibit very high round trip times and packet loss. This seemed to correlate with a significant increase in bandwidth through the converged fabric, such as when initiating a Live Migration and would then affect both vNICS connectivity. This would cause packet loss / connectivity loss for both the Live Migration and Cluster Heartbeat vNICs which in turn would trigger all sorts of horrid goings on in the cluster. If we disabled VMQ on the physical adapters and the team multiplex adapter, the problem went away. Obviously disabling VMQ is something that we really don’t want to resort to.

So…. The decision to refresh the environment with 2012 R2 across the board (which was also driven by other factors and not just this issue alone) was accelerated.

In the new environment, we replaced the Quad Port Broadcom 5720 Daughter Cards in the hosts with new Intel i350 QP Daughter cards to keep the NICs identical across the board. The Cluster heartbeat / Live Migration networks now use an SMB Multichannel configuration, utilising the same two NICs as in the old design in two isolated untagged port VLANs. This part of the re-design is now working very well (Live Migrations now complete much faster I hasten to add!!)

However…. The same VMQ issues that we witnessed previously have now arisen on the production VM Switch which is used to uplink the virtual machines on each host to the outside world.

The Production VM Switch is configured as follows:

  • Same configuration as the original infrastructure: 4 Intel 1GbE i350 NICs, two of which are in one physical quad port NIC, whilst the other two are in an identical NIC, directly below it. The remaining 2 ports from each card function as iSCSI MPIO interfaces to the SAN. We did this to try and achieve NIC level fault tolerance. The latest Firmware and Drivers have been installed for all hardware (including the NICs) fresh from the latest Dell Server Updates DVD (V14.10).

  • In each host, the above 4 VM Switch NICs are formed into a Switch independent, Dynamic team (Sum of Queues mode), each physical NIC hasRSS disabled and VMQ enabled and the Team Multiplex adapter also has RSS disabled an VMQ enabled. Secondly, each NIC is configured to use a single processor core for VMQ. As this is a Sum of Queues team, cores do not overlap and as the host processors have Hyper Threading enabled, only cores (not logical execution units) are assigned to RSS or VMQ. The configuration of the VM Switch NICs looks as follows when running Get-NetAdapterVMQ on the hosts:

Name                           InterfaceDescription              Enabled BaseVmqProcessor MaxProcessors NumberOfReceive
                                                                                                        Queues
----                           --------------------              ------- ---------------- ------------- ---------------
VM_SWITCH_ETH01                Intel(R) Gigabit 4P I350-t A...#8 True    0:10             1             7
VM_SWITCH_ETH03                Intel(R) Gigabit 4P I350-t A...#7 True    0:14             1             7
VM_SWITCH_ETH02                Intel(R) Gigabit 4P I350-t Ada... True    0:12             1             7
VM_SWITCH_ETH04                Intel(R) Gigabit 4P I350-t A...#2 True    0:16             1             7
Production VM Switch           Microsoft Network Adapter Mult... True    0:0                            28

Load is hardly an issue on these NICs and a single core seems to have sufficed in the old design, so this was carried forward into the new.

The loss of connectivity / high latency (200 – 400 mSec as before) only seems to arise when a VM is moved via Live Migration from host to host. If I setup a constant ping to a test candidate VM and move it to another host, I get about 5 dropped pings at the point where the remaining memory pages / CPU state are transferred, followed by an dramatic increase in latency once the VM is up and running on the destination host. It seems as though the destination host is struggling to allocate the VM NIC to a queue. I can then move the VM back and forth between hosts and the problem may or may not occur again. It is very intermittent. There is always a lengthy pause in VM network connectivity during the live migration process however, longer than I have seen in the past (usually only a ping or two are lost, however we are now seeing 5 or more before VM Nework connectivity is restored on the destination host, this being enough to cause a disruption to the workload).

If we disable VMQ entirely on the VM NICs and VM Switch Team Multiplex adapter on one of the hosts as a test, things behave as expected. A migration completes within the time of a standard TCP timeout.

VMQ looks to be working, as if I run Get-NetAdapterVMQQueue on one of the hosts, I can see that Queues are being allocated to VM NICs accordingly. I can also see that VM NICs are appearing in Hyper-V manager with “VMQ Active”.

It goes without saying that we really don’t want to disable VMQ, however given the nature of our clients business, we really cannot afford for these issues to crop up. If I can’t find a resolution here, I will be left with no choice as ironically, we see less issues with VMQ disabled compared to it being enabled.

I hope this is enough information to go on and if you need any more, please do let me know. Any help here would be most appreciated.

I have gone over the configuration again and again and everything appears to have been configured correctly, however I am struggling with this one.

Many thanks

Matt


Win8.1 Host - In Place Upgrade to Win 10 ? Hyper-V SSD aware ?

0
0

I am currently running a Win 8.1 Pro workstation with a couple of Win8.1 vm under Hyper-V ( I need to keep a couple of programs isolated from each other)

Is it possible and/or even "safe" to do an "in-place" upgrade to Win10 ? Or, do I need to export my VMs and do a ground up install and re-import?

Also, I would like to add a couple of SSD and move the VMs there. is Hyper-V SSD "aware" ? E.G, does it pass this along to the guests so they know to turn off defrag, superfetch,etc. 

Thanks!

Hyper-V 2012 standard - Guest VM aren't shutting down properly when host server shuts down.

0
0

We have a server 2012 standard hosting 2 Hyper-V machines, one is our Exchange and the other our App server.

We had a power outage last night and it looks that the host shut down cleanly but the VM's did not.I checked the event logs and the VM's are showing an unexpected shut down exactly the same time as the Host server. The host server event logs is showing "Event 6006" which to me is a clean shutdown.

Hyper-V Guest Shutdown Service is running on both VM's. On the Host that service was set to "Manual (Trigger Start)". I'm not sure what that means but I changed it to "Automatic (Trigger Start)"

Also, I tried to start HV Guest Shutdown Service on the host server but it just starts and stops. Is that because the startup type is set to "Trigger start"?

Any help is greatly appreciated. Thanks

Hyper-V integration service versions?

My Desktop is running Windows Server 2012 R2. I created a Windows 10 Guest and installed the integration services (from the HOST). Apparently the Guest integration service version is 10.0.10586.0. The Network Admins tell me the latest integration service version available is like 6.3 and they don't know how I got version 10.  Any ideas much appreciated! (This difference in versions is causing them trouble when they try to backup my VM using SCVMM 2012 R2, which I gather runs version 6.3.xx.)

TIA,

Hyper-v Cluster Behavior Query

Hi Team,

             I have a 06 Node Hyper-V Cluster and each running with 15 VM's (almost same size).

            Recently all the Physical Nodes got rebooted due to some issue, Once all the Nodes are up, None of the VM's are available in Node 4 and Node6, VM's running on the Nodes are moved to other one. I check the Hyper-v config reports, it looks perfect and I can able to move the VM's to Node 6 and 4 through failover cluster wizard

           Query:

                1. Kindly help to understand the Hyper-V cluster behaviour, why the VM's running on the Node 4 and 6 didn't come back to original one?

                2. What's the difference between Quick Migration and Live migration, while performing the migration any disconnect will be there?

Hey guys,

We're in deep trouble right now. Basically we have a VM that was accidentally got set to difference. it was stored on a separate disk alone, now that drive got full because of the avhd file. What's the best way to fix this? we never really had a differencing disk before so we don't know how to handle this.

Thanks

Hyper-V Generation 2 in Windows Server 2012 R2 keyboard not working

0
0

I'm trying to install a Hyper-V Generation 2 guest OS Windows Server
2012 on a host OS Windows Server 2012 R2 RTM from the technet
subscription.

What I found interesting from the description of the Hyper-V generation 2 is "This virtual machine generation provides support for features such as secure boot, SCSI boot, and PXE boot using a standard network adapter. Guest operating systems must be running at least Windows Server 2012 or 64-bit versions of Windows 8"

However, when I tried to install a Windows Server 2012 VM, my keyboard is not working and if I want to copy something from the clipboard I got below error.

I tried install Windows Server 2012 R2 as well, all works great.

So i'm wondering is it a bug for Windows Server 2012 installation or the above support guest OS description need to change to Windows Server 2012 R2?

Trouble getting virtual NICs to appear in VM

0
0
Hi all. We have the latest release of HyperV running on fully patched Windows 2008 host machine. We have 3 physical dual port NICs in the machine and we are having trouble creating virtual networks and having them show inside a guest VM.

Our guest VM is running Windows 2003 Web, SP2. No network adapters show up under Control Panel -> network connections

In device manager I notice a yellow exclamation under Other Devices. The details for this are as follows:

Unknown Device - Location: on Intel 82371AB/EB PCI to ISA bridge (ISA)

The drivers for this device are not installed.

Details: Value - ACPI\VMBUS\4&4B018EB&0

Here are the steps we took to create the virtual network:

1) Open Virtual Network Manager
2) Click Add on "External" virtual network
3) Select Intel Pro/1000 PT Dual Port Server Adapter (unused on host machine, but cable is plugged in) - External
4) Click OK to create virtual network
5) Go to Settings of VM and click Network Adapter
6) Select the virtual network we just created under Network: in Settings
7) Configure IP address etc on new VIRTUAL nic created on host machine. I have confirmed Hyper-V removed all checkboxes under properties of the physical NIC minus Microsoft Virtual Network Switch Protocol


Does anyone know what I am doing wrong? Is there some sort of driver/patch I am missing? Any help would be much appreciated!
