Cannot live migrate 2 of 12 VM's in FCM, when trying to live migrate these 2 VM's they get to around 48% and then the live migration stops. We've tried many things to resolve this, I'm just wondering if we've missed something.
Troubleshooting steps taken:
1. Settings > Management > Name, check for Notes in the properties
2. Check for files or lock folder in C:\ProgramData\Microsoft\Windows\Hyper-V\Virtual Machines
3. Adjusting VM migration timeout using HKEY_LOCAL_MACHINE\Software\Microsoft\Microsoft System Center Virtual Machine Manager Server\Settings\LiveMigrationTimeoutSecs
4. Verifying no other users are canceling live migration
5. Verifying the cluster nodes have identical hardware
6. Attempting to migrate to a different node
7. Running the Cluster Validation Wizard within the FCM to test the cluster
8. Questioning if underlying issue appears to be not with the cluster itself, but the VM
9. Verifying cluster host live migration success for other VM's
10. Uninstalling Veeam to verify Veeam is not causing issues during backup
11. Attempting to live migrate VM with PowerShell
12. Verifying BIOS revision is same on all 4 nodes
13. Verifying Jumbo packets are disabled on all NICs.
14. Confirming where VHD resides and if permissions are correct on location
15. Attempting storage only live migration, which was successful
16. Moving MRT & RCD files and attempting to live migrate which was not successful
17. Trying to live migrate after a successful quick migration
18. Tried enabling Processor compatibility mode
19. Verifying patch level of cluster nodes
20. Check for XML file cache at C:\ProgramData\Microsoft\Windows\Hyper-V\Virtual Machines Cache
21. Editing Registry for NetworkBufferCount at HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization\Migration
22. Considered disabling Hyperthreading but cannot be done
23. Verified VM's do not use shared VHD Sets
25. Verified vCPU and vRAM among guest VM's
26. Verified Processor > NUMA, does "Maximum amount of memory (MB)" matches the same setting under Memory > RAM or Memory > Maximum RAM
