Dear, Environment: Linux 4.1.18 with Xen 4.6.1 Network card hardware: 2x Intel 4-port I350Dom0: LACP bond on eth3,eth4,eth7,eth8 with eth3 and eth4 on the first I350 card, eth7 and eth8 from the second I350 card. Bond in bridge. Dom0: eth1 and eth2 from first I350 card and eth5 and eth6 from second card, each in a bridge

When booting a Linux domU with kernel 4.1.18 and igb driver 5.3.4.4,
booting works when we boot with:
1. only LACP bond: vif = [ 'bridge=xen_bond0' ] 2. eth1 bridge: vif = [ 'bridge=xen_eth1' ]3. eth1+eth2+eth5+eth6 bridge: vif = [ 'bridge=xen_eth1','bridge=xen_eth2','bridge=xen_eth5','bridge=xen_eth6' ] But as soon as we put the bond together with one of the other bridges (eg: vif = [ 'bridge=xen_bond0','bridge=xen_eth1' ]) we cannot get the domU to start and get the traces below. Booting the same machine with kernel 3.2.20 and igb driver 4.1.2 has been working fine on XEN 4.1.2 and still works on XEN 4.6.1 if we use it to boot the domU. So not sure if it is XEN, kernel, config or IGB driver related. Also our Windows HVM guests do not have a problem with it either and boot just fine on both the bond and the other bridges. Please advice. Many thanks in advance.
