Best practices on Hyper-V VMs migration/management

$
0
0

Hello,

Currently, we have Hyper-V running on our old server(Windows Server 2008) with all the VMs stored locally.

We are planning to get a new Windows Server 2012 R2.

I was advised on the opportunity to move the VMs off the server to the dedicated workstation machine(Windows 8.1).

My question is it a good idea to keep the VMs on the workstation, while managing them from Windows Server 2012?

I need your advice on this.

All ideas welcome.

Thanks

Ilya R.



the vm and host networking components failed to negotiate protocol version '4.0'

Hi,

I have the problem that when I start a VM with windows server 2012 on a hyper-v v2 host, it takes very long till the VM get bind the static or dynamic ip adress. I tried both, static and dynamic. In every case I see at the event viewer the following error:

the vm and host networking components failed to negotiate protocol version '4.0'

After a few minutes the VM gets bind the IP an everything works fine. But at the next time I reboot the machine the same failure appear.

Trying to use legacy network adapter results in the same problem. After this I tried to export the vm to a hyper-v v3 host. At first boot time
the problem didn't appear and the vm get's bind the ip adress without problems. Then after upgrading the integration services to hyper-v v3
version the same problem appears but without register it in the event viewer.

Does anybody know how I can fix this problem?

Kind Regards,
Marcus

Activating OS in guest virtual machines

Hi all,

Our customer need us to install Windows Server 2012 R2 Datacenter on 6 servers using Windows server 2012 R2evaluation media then install Hyper-V cluster on these servers. After that, we will install 7 virtual machines with Windows Server 2012 R2 Standard as an operating system on that Hyper-V cluster. My question is:Will VMs get automatically activated once the Hyper-V hosts are converted from evaluation to Datacenter with the licensed keys that the customer will install after they purchasethem?

Hyper-V Integration Services Stopped

Hi,

I have looked thru the forums and seem to be hitting a dead end or my search skills are failing. Anyhow, I have 2 Windows 2012 R2 DataCentre hosts running. They are running Hyper-v exclusively. I just noticed the other day that all the services for Hyper-V are stopped except for Virtual Machine Management. If I click on any of the stopped services, it will start up then promptly stop. It will give an error of:The Hyper-V x service on local computer started and then stopped. Some services stop automatically if they are not in use by other services or programs. I have reviewed my Windows Event logs and there are no warning or errors.

Some other background, there is SCCM 2012 R2 (5.0.7958.1401) in the environment, but no SCCM agent is installed at the moment. There is also VMM 2012 (3.2.7672.0) and the agent for this is installed on both hosts. Both of the hosts have been re-imaged in the last 2 months, so I don't think it's some weird age related weirdness. I also removed the hyper-v role from one of the hosts, rebooted and then re-added it. This made no difference. I also tried to add about of services to the restrictedservices in the registry as I had come across this in the wild of the internet, but this made no difference.

Any thoughts, idea's?

The VM and host networking components failed to negotiate protocol version '5.0'

I have been searching for a fix for this issue for sometime.

The VM and host networking components failed to negotiate protocol version '5.0'

and

The VM and host networking components failed to negotiate protocol version '4.0'

this error have been posting on the host server 2008 R2, with a hyper-V running server 2012 R2, which is the eval version vhd from Microsoft.

I have tried the patch on the server 2008 R2 host and the nic delete and rescan option with varied reboots and such between each step of the process just to try every possible combination.

The error persists. Are there any other suggested solutions for fixing this problem. Also the drivers have all been updated along with the system firmware.

thanks,

Adding a Node to Hyper-V Cluster

Hello All.............I am running Private Cloud (Infrastructure as a Service) in my environment with Hyper-V Failover Cluster and Windows Azure Pack.  There is Remote Desktop Gateway in place as well.

I want to add a node to a Hyper-V Failover Cluster.   What are the things that I need to consider before adding a node to the Cluster?

VMM Agent?

RDG Certificate?

I would appreciate if someone could guide me through it as to what I need to keep in mind before adding a node and how I should plan it and do it.  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.

Hyper-V convert to direct disk

$

My 2012 R2 Server is running on 5 RAID6 HDDs + 1 spare (WD REDs). It's used as a storage server, with two Windows 8.1 Pro Hyper-V clients. The problem is that the disk access in general is kind of slow. So my idea is to move the windows to RAID1 SSD, and move both Hyper-V clients to another RAID1 SSD, and keep RAID6 HDDs just for users files storage.

Both Hyper-V setup as dynamic disk files. Is there a way to convert them and run them as direct disk access from SSD divided into two partitions?

Thanks so much for any help.

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 ?

Hi

I have a Server 2012 with Hyper-V on it.

I need to shutdown all machines but an ORDERLY shutdown, not just turnoff.

the host is not a member of the domain but of a workgroup, all VM are Domain members...

Does anyone have an example script to give me?

Thank you!

Manager Hyper-V Server from Another Subnet

$

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!

MPIO Dual Controller ALUA BSOD in Cluster

$

Hello,

I'm having issues with iSCSI MPIO on ALUA-enabled dual controller SAN (Promise VessR2600tiD).
The device is 2012 R2 certified (http://www.windowsservercatalog.com/item.aspx?idItem=752f327a-05c8-ec2a-95c5-671460e6b7a9&bCatID=1282) with current firmware. We are running VM workloads on 2 LUN's atm over dedicated 10G iSCSI connections (Intel X540-T1/T2 NIC's) in a 2-node Hyper-V cluster.

The NIC's have stripped down protocol support (ipv4 only with jumbo frames) and dedicated subnet. 
Everything works fine until mpio kicks in. When I try to failover a controller on the SAN (change preferred one), I get strange BSOD's msdsm.sys. 

What's stranger is that I basically tried this recently:
2x Hyper-V servers in a cluster, no MPIO, on LUN1, LUN2 on CTRL 1
1x STANDALONE server WITH MPIO on LUN3 (Lun masking turned on) on CTRL2

If I change ALUA preference on LUN3 -> CTRL1, Hyper-V cluster servers get BSOD, not the standalone server. Also,
on the standalone server, the Path State stays Active/Optimized, although TPG State changes to standby and the second portal becomes active.

The vendor wasn't able to help me and I'm kinda at wit's end here. It seems that no matter what server I try to setup MPIO on, the cluster servers get BSOD, even if the server with MPIO is not a part of the cluster nor it shares LUN with the cluster. There's nothing in the server nor SAN logs.

Hyper-V 2012 removing replication on virtual machine

Hi all

If you remove replication from a virtual machine how long does this take to update the replication partner? Is there a best practice for removing? 

I have a three node and two node cluster running on Windows 2012. I removed replication from a VM and the partner still shows replication enabled. 

Thanks in advance.

Recommendations for Sizing Hyper-V

$

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

Virtual Network Adapter Not Working

$

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


Hyper V 2012 , error cant access the virtual machine settings

$

Hello Guys,

we have 2 Hosts installed with Windows Server 2012 Standard. These 2 Hosts are configured as an Failover-Cluster. Also we have an IBM Storwhize connected directly via SCSI to both hosts. Its configured as a shared volume in Failover Cluster Manager.

we have the following problem:

From time to time, when i want to open hyper-v settings on host002 , i cant access this, i get this error:

cant access hyper-v settings, running out of memory or disk

But my disk space and RAM is OK. the strange thing is that the virtual machines are accesable via RDP.

To solve this issue temporarily i have to reboot HOST002. If i reboot host002 then it works, but host001 has the same problem.. I think its an issue with the Failover Configuring, because all that started when we have shutted down both servers, then i think failover cluster wanted to move these virtual machines (high availability) and then get in errors.

it would be very glad if anyone can help me (remote or whatever)

All virtual machines are running perfectly, but i cant access the settings and our backup tool VEEAM cant backup the virtual machines..

Thanks Edmond

Hi, all

I have a problem in the management of the machines in Hyper-V, when I try to open the VM console I get the following error:

an error occurred while attempting to launch the Virtual Machine
  Connection application for the selected virtualmachine

however when I click on the settings I get this other:

Cannot access the settings for the selected virtual machine. the
  computer "localhost" failed to perform the requested operation

I tried to add my user account in InitialStore.xml with AzMan,

with icacls “<virtualmachinefolder>” /grant “NT VIRTUAL MACHINE\<virtualmachineguid>”:F /T

 but did not solve my problem.

Any idea?

tnx for now

Hyper V what to do to maintain?

$

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
