Thanks again, Tmanok!
The confusing aspect of this is that I'd already live migrated several VM's (Ubuntu - between the same cluster members) so I thought my config is solid. At any rate here's the info you requested:
nodes: pve and pveNUC
I'm attempting to live migrate a Windows10 VM from one cluster node to another and I consistently receive the following error:
drive-ide0: Cancelling block job
drive-ide0: Done.
