We have a 2 node cluster with S2D Server 2019 that live migrates when you do it nicely perfectly fine
Cluster validation shows no problems
When we power off a server for testing the migration gets to 59% hangs for a bit then stops and the following is logged:
Event iD 1069 Cluster resource 'Virtual Machine Configuration TEST-VM' of type 'Virtual Machine Configuration' in clustered role 'TEST-VM' failed. The error code was '0x139f' ('The group or resource is not in the correct state to perform the requested operation.'). The Migration times out then the TEST-VM restarts on the other node.
Further testing shows that this only happens when we have 8 or 10 CPU's and 32GB of RAM on the TEST-VM.
If we only use 1 CPU and 1024MB RAM when we test the power off the live Migration works as it should.
Dell PowerEdge R640's with 2x 8core CPU and 128GB Ram each.
Getting stuck here as 1069 is a generic error for something isn't available, we think the virtual machine configuration file is not able to be found / move. the only other events are to do with the networking going down, but as we turned a node off this is to be expected.
