I've tried upgrading the BIOS, compiling the latest igb kernel module from 
intel.com and enabling/disabling all NIC related settings in the BIOS 
(including SR-IOV). I've also confirmed vlans work on the exact machine and 
switch configuration using CentOS. The only thing that worked for XCP was 
switching to bridge instead of openvswitch.

Best regards,
Adrian Costin

Just in case that this is a local problem to you. Can you provide NIC 
information, xapi log, and any other relevant information that could try to 
explain the differences in both the Open vSwitch case and the bridge case?

Thanks,
Todd
