This article provides information on solving the issues when live migrating virtual machines.
Applies to: Windows Server
Original KB number: 4558514
Basic troubleshooting checklist
Check the hosts are at the same level of patching and whether they can update to the latest rollup.
Update the BIOS, firmware and third party drivers.
Check whether the virtual machines have the latest matching integration services.
Check whether the migration is authorized on each side.
Check whether the protocol used is identical on each side.
Check whether the TCP Port 6600 and 3343 (for clustering) are listening on both sides.
Check compatibilities issues by running a
Compare-VMcommand. Provide the name of the VM and the destination host. For example:Compare-VM -Name <vm_name> -DestinationHost <host_name>Check whether any group policy object is preventing the migration from occurring. Verify that the following policy have at least the default settings.
- Open GPEDIT.MSC and navigate to Computer Configuration\Windows Settings\Security Settings\Local Policies\User Rights Assignment.
Open Create symbolic links and check whether the following user accounts are listed:- Administrators
- NT VIRTUAL MACHINE\Virtual Machines
- Log on as a service
- NT SERVICE\ALL SERVICES
- NT VIRTUAL MACHINE\Virtual Machines
- Open GPEDIT.MSC and navigate to Computer Configuration\Windows Settings\Security Settings\Local Policies\User Rights Assignment.
Check for the antivirus exclusions. For more information, see Recommended antivirus exclusions for Hyper-V hosts.
Check the corruption of the Registry.pol file:
Run notepad and open C:\Windows\System32\GroupPolicy\Machine\Registry.pol. The file must start with the PReg signature.Compare permissions on the folders containing the virtual machines files with a working host with the same operating system level.
Next, find the event IDs that you encounter during live migration issue from the following sections.
Event ID 21502
Information regarding Event ID 21502
Live migration failed because a virtual switch used by the VM doesn't exist on the destination node "Host2"
Description
Live migration of VM failed. VM failed to live migrate because a virtual switch used by the VM doesn't exist on the destination node "Host2".
Action
The virtual switch must have the same name on all nodes.
If a virtual machine is connected to a virtual switch that doesn't exist on the destination node, then live migration fails at < 10%.
Give the virtual networks identical names. Refresh the virtual machine configuration so that network changes are reflected in cluster, and then try the live migration again.
Resolution
Open the Hyper-V Manager console and select Virtual Switch Manager. If the virtual switch doesn't exist, create or rename it with the same name and settings such as in other hosts.
Make sure to select the correct virtual switch under the VM's settings.
Live migration failed because the action "Move" didn't complete. Error Code: 0x80071398
Description
Live migration of VM failed.
Action
Right-click virtual machine > Information details > Show details. You see the following information:
The action "Move" didn't complete.
Error Code: 0x80071398
The operation failed because either the specified cluster node isn't the owner of the group, or the node isn't a possible owner of the group.
0x1398 5016 ERROR_HOST_NODE_NOT_GROUP_OWNER
The operation failed because either the specified cluster node isn't the owner of the group, or the node isn't a possible owner of the group.
Resolution
Open Windows PowerShell with Run as administrator, and run the following cmdlets:
- Get-clusterResource -name "Virtual Machine VM1" | Get-clusterOwnerNode
- Get-clusterResource -name "Virtual Machine Configuration VM1" | Get-clusterOwnerNode
The owner node must have all cluster nodes.
Alternatively, open the Failover Cluster Manager (FCM) under roles, select the virtual machine like shown in the following screenshot. On the bottom tab, select Resource, right-click Virtual MachineVM1, select the Advanced Policies tab. Check that all nodes are selected. Do the same for "Virtual Machine Configuration VM1. Make sure the VM has the same virtual switch on all nodes.

qtree oplocks qtree_name enableqtree oplocks qtree_name disable
If the cifs.oplocks.enable option is set to On, the qtree oplocks cmdlet for a qtree takes effect immediately. If the cifs.oplocks.enable option is set to Off, the qtree oplocks command doesn't take effect until you change the option to On.
Here's how to fix this issue:
- Replace the NetApp filer with a Windows 2016 based File server. Alternatively, update the NetApp file to the latest
Ontap9.*. version. - Make sure that the Windows Server 2016 based Hyper-V nodes are updated with the latest cumulative update. Similar issues are resolved after you applying CU Feb 2019 or a later version.
Failed live migration of 'Virtual Machine VM1' at migration source 'CLU8N1' with error codes 80042001 and 8007000D
Description
Live migration of 'Virtual Machine VM1' failed.
Virtual machine migration operation for 'VM1' failed at migration source 'CLU8N1'.
When running an SMB live migration between nodes in a Windows 2019 (RS5) Hyper-V cluster, a failure occurs on all VMs that point to a specific node:
Virtual machine migration operation for 'VM1' failed at migration source 'CLU8N1'.
Action
Filter error codes 80042001 and 8007000D on the VM name to collect VML traces on the source.
Under RS5, live migration through SMB of all the VMs to a specific node fails on the source because the HKLM\SYSTEM\CurrentControlSet\Control\ComputerName\ComputerName: ComputerName isn't in UPPERCASE.

Event ID 20413
Description
Live migration fails at 90%~100%, and quick migration fails during virtual machine configuration online.
Action

Resolution
Make sure the virtual machine network settings are correct.
Check if the source and destination virtual network are in the same subnet. If the aren't, run the ipconfig /renew cmdlet to resume the network connectivity. Alternatively, assign a new IP address to the virtual machine if a static IP address is used.
Event ID 21125
Description
Configuration setup for live migration failed on the destination node.
Action
Make sure that name of the virtual network is the same on the source and destination nodes and try the live migration again.
