Greetings. We have a cluster with the following network configuration, most of which is working correctly but when I try to add a second NIC to a VM it can't see the network. Here's the network layout:

Host level - everything works here:
bond0 (used for management only)
bond1 -> bond1.110 (VLAN, MTU 9000) -> netappbr0 (bridge with IP, MTU 9000, connects to storage)
bond1 -> vmbr1 (VLAN aware, MTU 9000, used for VM connectivity)

Cluster level SDN:
vmbr1 -> Zone Data (vlan, MTU 1500) -> VNet VLAN200 (tag 200, vlan aware, works fine)
vmbr1 -> Zone Data (vlan, MTU 1500) -> VNet VLAN210 (tag 210, vlan aware, works fine)
vmbr1 -> Zone Storage (vlan, MTU 9000) -> VNet VLAN110 (tag 110, vlan aware, DOES NOT WORK)

I'm able to verify that the MTU works without fragmentation from both netappbr0 and any VM connected to either VLAN200 or 210 (the latter two at 1500). What am I missing here as to why connections using VLAN110 aren't seeing anything on that network?
