Hi, I have a strange issue here, with my 12 Node Hyper-V 2012R2 Cluster, I can live Migrate Between All nodes except two.! Node 7 and Node 10
I can quick Migrate to these Nodes, and Live migrate from them. but cannot Live Migrate any of my virtual Machines to ether of them. I can live migrate between the other 10 nodes without issues. all the config looks fine, and cluster validation passes ok.
Should the Live Migration Subnet be routable to the HOST Subnet, the host subnet is our normal fully routable Server subnet where all our servers sit. ????
I have a dedicated NIC team for Live Migration, no DNS, its none routable 10.201.242.x network. the IP is pingable from all other nodes, and network status is all correct in the Cluster manager.
Network binding is correct, and AV is off, firewall is also off on all my nodes.
I am attempting the live migrate from the cluster manager. not SCVMM (which also fails too).
Events logged are in order :-
Hyper-V VMMS event ID 20306 No connection could be made because the target actively refused it.
Hyper-V VMMS event ID 21024 Virtual Machine Migration failed at source.
Hyper-V-High-Availability 21111 Live Migration Failed
Hyper-V-High-availability 21502 Connection could not be made because the target machine actively refused it.
any help or ideas appreciated, scratching my head on this one. !!
SPN registrations are all correct, I have even tried using the host management NIC as the selected preferred LM NIC, but it makes no difference. all my nodes are fully patched to date.
I have a 2012 12 Node Cluster two setup identical which has no issues, except it uses CSV disk, where as my new 2012R2 cluster uses an SMB 3.0 SOFS cluster.
thanks
Mark
