Cannot perform a live migration while replication is enabled

I have two Server 2012 machines that I am running hyper-v on (just testing for now). I can right click on a virtual machine and move it (live migration) to the other server with no issues. I can also enable replication on the VM and that
appears to work properly. However, if I have replication enabled on a VM I am unable to perform a live migration. I receive an error that says the VM already exists on the destination server (because of the replication).
Is there any way to perform a live migration while replication is enabled?

I can't think of a reason why you would want to anywhere else but a test environment. Replication's intended use is DR across a WAN between two physical location (there are others, but this is primarily why it was created). If Office1 burns down, you can
boot your Replica at Office2. Live Migration is for local HA. If Server1 has a hardware failure, Live Migrate to Server2.
If everyone could simply Live Migrate over their WAN link between offices, Replication would be redundant. But getting a fast enough WAN link for this is extremely expensive, so Microsoft created Replication for high latency, low bandwidth WAN connections.
TL;DR, Replication and Live Migration are mutually exclusive in almost all environments. It's not even that they *can't* work together, it's just that there's no point in making them work together because they're for different use cases.

Vmm Protection Error, Unable to perform the live migration due to cloud protection issue for G2 system..Error (23833)

Error (23833)
The selected cloud does not support protection, or the recovery point objective requested for the virtual machine xxxx (30 seconds) is not within the range that the cloud supports.
Recommended Action
Select a different cloud, enable protection for the cloud, or change the requested recovery point objective for the virtual machine to a value greater than or equal to NO_PARAM seconds, and then try the operation again.

Microsoft has not provided me with much support on this issue, but I was able to resolve this myself. What you need to do is remove the DR Protection attribute from your VM using the command below.
Source:
Stop protecting a virtual machine
$vm = get-scvirtualmachine -Name "SQLVM1"
Set-SCVirtualMachine -VM $vm -ClearDRProtection
It is important to note that this command does nothing, unless the Azure Site Recovery provider is installed on your VMM server, and your VMM server is registered in ASR. Once I had run this command against my virtual machines, I was able to uninstall the
provider and unregister my server from ASR. Now my VM's are free to live migrate again.

Yes, definitely check your zoning/masking. Remember that with vHBA you have twice as many WWPNs to account for. Performing a live migration makes use of both pairs during the transfer from one host to the other - one set is active on the machine
currently running and the second set is used to ensure connectivity on the destination. So if you are using Address Set A on Host1, Host2 will try to set up the fibre channel connection using Address Set B. If you do a quick migration, you would
continue to use the same Address Set on the second host. That's why you most likely need to check your zoning/masking for the alternate set.

Losing pings on live migration

I currently have a 2 node OVM 3.1.1 cluster, fully patched, and have noticed that I lose network connectivity while performing a live migration. I have separate networks for VM's and for live migration. I am new to OVM so I do not know if this is typical or not. It appears that every time I migrate a VM, the client will lose connectivity to the network for anywhere from 5 - 20 seconds.

Are you talking about lost pings to the guest VM that is live migrated? If yes, that I'd suppose that to be normal behaviour, since there has to be some interruption, once the memory contents is finally synchronized between the source and the target VM server.
Depending on much RAM is used by the running VM and the speed of your network, this "outage" might vary in time, but there will surely always be some time span where pings to the VM that is being live migrated get lost.

Live Migrating Virtual Machines with Shared VHDx

I am facing problems when live migrating a Virtual Machine that is using Shared VHDx. The Virtual Machine gets migrated that is the configuration gets migrated, but the Virtual Machine fails to start up and if manually tried, it fails too.
What is the method to to live migrate virtual machines that are using Shared VHDx. Thanks in advance.

Another couple of gotchas:
You cannot do host-level backups of the guest cluster. This is the same as it always was. You will have to install backup agents in the guest cluster nodes and back them up as if they were physical machines.
You cannot perform a hot-resize of the shared VHDX. But you can hot-add more shared VHDX files to the clustered VMs.
You cannot Storage Live Migrate the shared VHDX file. You can move the other VM files and perform normal Live Migration.
as Long as you have your shared VHDx on a SMB3 Share you also could have the Nodes of the Guest Cluster on different Hyper-V Hosts.

Live migration support in ops Cenetr?

Dose Enterprise Manager Ops Center 11gr1 support the new live migration feature?

It does not natively provision the necessary bits for Live Migration (i.e. OVM Server 2.1), but if you install OVM 2.1 on your OVM Servers, you can perform the live migrations through OC (assuming your firmware etc. are all at Live Migration minimums too).
The syntax for the migrations didn't change, so "under the covers" a live migration is performed if possible.

Shared nothing live migration over SMB. Poor performance

Hi,
I´m experiencing really poor performance when migrating VMs between newly installed server 2012 R2 Hyper-V hosts.
Hardware:
Dell M620 blades
256Gb RAM
2*8C Intel E5-2680 CPUs
Samsung 840 Pro 512Gb SSD running in Raid1
6* Intel X520 10G NICs connected to Force10 MXL enclosure switches
The NICs are using the latest drivers from Intel (18.7) and firmware version 14.5.9
The OS installation is pretty clean. Its Windows Server 2012 R2 + Dell OMSA + Dell HIT 4.6
I have removed the NIC teams and vmSwitch/vNICs to simplify the problem solving process. Now there is one nic configured with one IP. RSS is enabled, no VMQ.
The graphs are from 4 tests.
Test 1 and 2 are nttcp-tests to establish that the network is working as expected.
Test 3 is a shared nothing live migration of a live VM over SMB
Test 4 is a storage migration of the same VM when shut down. The VMs is transferred using BITS over http.
It´s obvious that the network and NICs can push a lot of data. Test 2 had a throughput of 1130MB/s (9Gb/s) using 4 threads. The disks can handle a lot more than 74MB/s, proven by test 4.
While the graph above doesn´t show the cpu load, I have verified that no cpu core was even close to running at 100% during test 3 and 4.
Any ideas?

InvalidOperationException - "Cannot perform this operation while dispatcher processing is suspended."

I have a WPF application in .NET 4.5. The latest version of the map control (version 1.0.1.0) is causing an issue if it is used within a datatemplate. This does not happen with the previous version I was using from Nuget (version 1.0.0.0). As

Are dev team has looked into this and I believe they have found the issue. They are working on putting together a new release. Also, Microsoft never officially released a Nuget package, someone just took some old buggy libraries and posted them on Nuget
without asking Microsoft. We are planning to make an official Nuget package.

Win 2012 shared-nothing live migration slow performance

Win 2012 shared-nothing live migration slow performance
Hello,
i have two standalone hyper-v servers - A) 2012 and B) 2012 r2.
I tried live migration on non-shared storage between them. The functionality is alright but performance is low. The copying take a long time with max 200 Mbps.
I am not able to find the bottleneck. Network a disk performance seems to be good. It is 1Gbps network and when I tried simple copy paste the vhd file from A to B through cifs protocol, the speed was about almost full 1Gbps - it was nice and fast.
Is it feature? I am not able reach full network performance with shared-nothing live migration.
Thank you for reply
sincerely
Peter Weiss

Hi,
I don’t found the similar issue with Hyper-V, Does both of your hosts have the chipsets in the same family? Could you try to switch the three Live Migration Performance
Option method then monitor again? Or It seems there may have some disk or file system performance issue, please try to update your RAID card firmware to the least version.

V-HBA Guest VM cannot Live Migration

Hi All,
I'm using Windows Server 2012 Data Center OS and configured the for the hyper-V server role with Fail-over cluster (4 Node – Cluster).
Each Physical server installed with Two Qlogic HBA Adapters.
We have configured following configuration on hyper-v Server and SAN (HP) storage.
Enabled the Virtual SAN Manager.
Created Each Hyper-V Host Virtual Fiber channel Switch. Each Host configured two adapters. (Fibre Channel SAN 1 / Fibre Channel SAN 2) .
Using the HP storage and enabled the switch port level (N_Port ID Virtualization (NPIV).
Created new VM and assign new two vHBA Adapters. Each adapter having two sets of wwn numbers.
Each Adapter SET A wwn Address discovered by SAN switch and configured the zone . However SET B not discovered but we manually created the zone for SET B for both Adapters.
Present the Storage to the VM and installed the MPIO. SAN disk visible on the VM disk management.
During the live migrate the VM to different host I’m getting below error.
Live migration of 'Virtual Machine TEST-Server' failed.
Virtual machine migration operation for 'TEST-Server' failed at migration destination 'HV02'. (Virtual machine ID 378AE3E3-5A4F-4AE7-92F8-D47855C2D1C5)

I need some support from Expert for this issue. I’m trying to configure the Guest Cluster with HBA. The Quick Migration working fine but still failing with live migration. I want to resolve the live migration issue.

Server 2012 r2 live migration fails with hardware error

Hello all, we just upgraded one of our hyper v hosts from server 2012 to server 2012 r2; previously we had live replication setup between it and another box on the network which was also running server 2012. After installing server 2012 r2 when a live migration
is attempted we get the message:
"The virtual machine cannot be moved to the destination computer. The hardware on the destination computer is not compatible with the hardware requirements of this virtual machine. Virtual machine migration failed at migration source."
The servers in question are both dell, currently we have a poweredge r910 running server 2012 and a poweredge r900 running server 2012 r2. The section under processor for "migrate to a physical computer using a different processor" is already checked
and this same vm was successfully being live replicated before the upgrade to server 2012 r2. What would have changed around hardware requirements?
We are migrating from server 2012 on the poweredge r910 to server 2012 r2 on the poweredge r900. Also When I say this was an upgrade, we did a full re install and wiped out the installation of server 2012 and installed server 2012 r2, this was not an upgrade
installation.

The only cause I’ve seen so far is virtual switches being named differently. I do remember that one of our VMs didn’t move, but we simply bypassed this problem, using one-time backup (VeeamZIP, more specifically).
If it’s one-time operation you can use the same procedure for the VMs in question -> backup and restore them at new server.
Kind regards, Leonardo.

Hyper-V Live Migration Compatibility with Hyper-V Replica/Hyper-V Recovery Manager

Hi,
Is Hyper-V Live Migration compatible with Hyper-V Replica/Hyper-V Recovery
Manager?
I have 2 Hyper-V clusters in my datacenter - both using CSVs on Fibre Channel arrays. These clusters where created and are managed using the same "System Center 2012 R2 VMM" installation. My goal it to eventually move one of these clusters to a remote
DR site. Both sites are connected/will be connected to each other through dark fibre.
I manually configured Hyper-V Replica in the Fail Over Cluster Manager on both clusters and started replicating some VMs using Hyper-V
Replica.
Now every time I attempt to use SCVMM to do a Live Migration of a VM that is protected using Hyper-V Replica to
another host within the same cluster,
the Migration VM Wizard gives me the following "Rating Explanation" error:
"The virtual machine virtual machine name which
requires Hyper-V Recovery Manager protection is going to be moved using the type "Live". This could break the recovery protection status of the virtual machine.
When I ignore the error and do the Live Migration anyway, the Live migration completes successfully with the info above. There doesn't seem to be any impact on the VM or it's replication.
When a Host Shuts-down or is put into maintenance, the VM Migrates successfully, again, with no noticeable impact on users or replication.
When I stop replication of the VM, the error goes away.
Initially, I thought this error was because I attempted to manually configure
the replication between both clusters using Hyper-V Replica in Failover Cluster Manager (instead of using Hyper-V Recovery Manager).
However, even after configuring and using Hyper-V Recovery Manager, I still get the same error. This error does not seem to have any impact on the high-availability of
my VM or on Replication of this VM. Live migrations still occur successfully and replication seems to carry on without any issues.
However, it now has me concern that Live Migration may one day occur and break replication of my VMs between both clusters.
I have searched, and searched and searched, and I cannot find any mention in official or un-official Microsoft channels, on the compatibility of these two features.
I know vMware vSphere replication and vMotion are compatible with each otherhttp://pubs.vmware.com/vsphere-55/index.jsp?topic=%2Fcom.vmware.vsphere.replication_admin.doc%2FGUID-8006BF58-6FA8-4F02-AFB9-A6AC5CD73021.html.
Please confirm to me: Are Hyper-V Live Migration and Hyper-V Replica compatible
with each other?
If they are, any link to further documentation on configuring these services so that they work in a fully supported manner will be highly appreciated.
D

This can be considered as a minor GUI bug.
Let me explain. Live Migration and Hyper-V Replica is supported on both Windows Server 2012 and 2012 R2 Hyper-V.
This is because we have the Hyper-V Replica Broker Role (in a cluster) that is able to detect, receive and keep track of the VMs and the synchronizations. The configuration related to VMs enabled with replications follows the VMs itself.
If you try to live migrate a VM within Failover Cluster Manager, you will not get any message at all. But VMM will (as you can see), give you an
error but it should rather be an informative message instead.
Intelligent placement (in VMM) is responsible for putting everything in your environment together to give you tips about where the VM best possible can run, and that is why we are seeing this message here.
I have personally reported this as a bug. I will check on this one and get back to this thread.
Update: just spoke to one of the PMs of HRM and they can confirm that live migration is supported - and should work in this context.
Please see this thread as well: http://social.msdn.microsoft.com/Forums/windowsazure/en-US/29163570-22a6-4da4-b309-21878aeb8ff8/hyperv-live-migration-compatibility-with-hyperv-replicahyperv-recovery-manager?forum=hypervrecovmgr

Failed live migration from HyperV2012 to Hyperv2012R2 cluster

I’m at a loss on something and I was wondering if you could point me in the right direction. I tried to migrate a server from one of my 2012 hosts to a brand new verified Hyperv 2012 R2 cluster. I had already succesfully migrated 5 others
from there but this one Sql 2012 guest gave me a problem.
When I tried to live migrate it, it failed. It said the hardware on the destination computer was not compatible. I did some research and one blog said that sometimes you migrate to different hardware and it fails, like processors. The guy
on the blog said to check the box under processor\compatibility to put the virtual processor in compatibility mode. I did that and tried again but it failed again. This blog said something about resource groups. The virt was “locked” at that
point.
I got frustrated so I just turned off the guest and copied the disks and rebuilt it on Aag with the same memory processor setting. I thought I was fine, but I looked at it the next day and in the failover cluster manager it shows the machine is “off”.
BUT the VM is actually running because the server is working. It’s a database server and the sites using it are up, and I can RDC to it. So I’m afraid to touch it.
And these are the errors from the event log
'Virtual Machine Configuration DEVDB1' failed to register the virtual machine with the virtual machine management service.
The Virtual Machine Management Service failed to register the configuration for the virtual machine '62AAD2B5-8E03-4B59-84E0-D52CBF36934B' at 'C:\ClusterStorage\Volume2\Devdb1\DEVDB1': The
system cannot find the file specified. (0x80070002). If the virtual machine is managed by a failover cluster, ensure that the file is located at a path that is accessible to other nodes of the cluster.
Cluster resource 'Virtual Machine Configuration DEVDB1' of type 'Virtual Machine Configuration' in clustered role 'DEVDB1' failed. The error code was '0x2' ('The system cannot find the file
specified.').
Based on the failure policies for the resource and role, the cluster service may try to bring the resource online on this node or move the group to another node of the cluster and then restart
it. Check the resource and group state using Failover Cluster Manager or the Get-ClusterResource Windows PowerShell cmdlet.
I think I moved it while it was in a funky state. I also think I was supposed to “export” the vm first. I guess I’m a newbie but I’m not sure what to do to fix it. Any advice is greatly appreciated.

I think i found at least part of the problem but i'm not sure. My new VM's configuration files and directory are called this.
D79490DB-48F9-40A4-9540-53F2532D3F7F

Still not sure what to do about that though.

Unable to live migrate VM (error 21502)

Hi,
I have four node Hyper-V cluster build on Windows Server 2012. I found an issue when one virtual machine is unable to live migrate to another cluster node with following error:
Live migration of 'Virtual Machine VM' failed.

It's possible to migrate VM in Stopped state but then the VM cannot start on new host with following error:
'Virtual Machine VM' failed to start.

Live storage migration works fine. When I migrate VM back to original node then VM starts correctly.
Thanks for any response.

Hi, Daniel,
Sometimes you might face failed live migration due to VMSwitches being named differently. So, the first thing to do is to make sure that VMSwitches on both hosts have the same name.
Also, you can try to take cluster offline and perform repairing procedure that appears to fix the mysterious issue causing live migrations of VMs to fail. ( Open Failover Cluster Manager -> Select the cluster name -> Take Offline
-> More Actions, click Repair.
Otherwise, if you’re short on time and willing to migrate VM as soon as possible, you can perform one-time backup/restore operation, using one of the free backup utilities available on the market (VeaamZIP or similar). In many way this
tool acts as zip-utility for VMs. It helped us a lot, when migration failed for whatever reason, and we didn't have enough time to find the root cause.
Kind regards, Leonardo.
