in oVirt with binding mode 4, and assign a logical network to the link
without specifying a VLAN, it works fine. I'm told the default untagged
VLAN is 494 (which is what I want). On the other hand, if I simply
hard-code VLAN 494 in the logical network setup, it doesn't work - I get no
network traffic. I'm told that the switch is setup correctly, and the
problem is on my side. How can I debug?

That sounds normal to me. Traffic coming in on the native untagged VLAN
wouldn't appear on the VLAN interface. I have a similar set up, and I've
assigned an unused VLAN as the native VLAN on the trunk, added the VLANs I
care about to the allowed VLANs list, and created the appropriate tagged
logical networks.
Thanks, Martin. I thought that the native VLAN would come through on the
VLAN interface as well. While this would explain why I couldn't get at
VLAN 494, it wouldn't explain why I couldn't get at another of the VLANS
on the same link -- still no traffic. I do a tcpdump and see nothing (but
the LACP stats show the link is up).
Jason.
