So I probably just misunderstand how this works, but here is what I thought should happen, in the Setup Host Network screen for this host I have the ovirtmgmt on VLAN100 with the bonded 20Gigabit interface performing the following. "Management, Display, Migration, VM and Default Route." Then I have the secondary 1 Gigabit interface just doing "VM" on VLAN12.

So there is connectivity from that interface to the storage. What I am trying to figure out is there a way to force it to do imports over the 20Gigabit interface that resides on VLAN100 instead of the slower VLAN12 interface, that is just there for general VM connectivity. >> >> >> Thank you for any advice or guidance on this matter. Can you share the ip addresses you have set on your host interfaces? I suspect that your VLAN12 interface has a X.X.12.Y address, sharing the same subnet as your NFS server. When a hypervisor connects to a storage server, it prefers using the same subnet. If you can move your NFS server to VLAN100, you can re-add it to the data ceneter using its new address. Then, hosts would use the X.X.100.Y address to connect to it.
