Andrei, Do the interfaces appear correct (i.e. are the correct interfaces plugged into the expected bridges in the libvirt config)?
We have yet to test 4.11, but we're about to get it into our lab. - Si ________________________________ From: Andrei Mikhailovsky <[email protected]> Sent: Thursday, April 5, 2018 4:51 AM To: users Subject: VPC issues after upgrading from 4.9.3 to 4.11.0 Hello, I have identified a critical VPC issue after we've upgraded to 4.11.0 on KVM hypervisors. The problem is the connectivity between network tiers within the VPC stopped working after the upgrade. Doing VPC restart with the Clean Up doesn't help. It seems that the VPC's iptable rules are all messed up and they reference wrong interfaces. The iptable rules are all created using the eth0 interface and not using the tier's corresponding network interface. For example: 0 0 SNAT all — * eth0 10.1.60.0/24 10.1.60.30 to:10.1.70.1 0 0 SNAT all — * eth1 10.1.60.30 0.0.0.0/0 to:178.248.108.109 0 0 SNAT all — * eth0 10.1.60.0/24 10.1.60.4 to:10.1.70.1 0 0 SNAT all — * eth1 10.1.60.4 0.0.0.0/0 to:178.248.108.104 0 0 SNAT all — * eth0 10.1.60.0/24 10.1.60.146 to:10.1.70.1 4 304 SNAT all — * eth1 10.1.60.146 0.0.0.0/0 to:178.248.108.44 The network interface that corresponds to the 10.1.60.0/24 is on eth6. The same happens with Could anyone suggest the fix for this? Thanks Andrei
