Hello, Kernel versions tested: 3.13, 3.14, 3.15Related debian bug report: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=738863
I'm not sure if this is a problem specific to openvswitch or KVM. I have a network setup where I have one openvswitch bridge setup, with various ports with VLAN tags and a firewall running as a guest. After upgrading to Linux 3.13, all guests with virtio interfaces with TSO enabled (the default) are unable to establish TCP connections via the guest firewall. ICMP ping works fine. If I disable TSO on the vnet interfaces (as outlined in the bug report above) guests are then able to communicate with each other.
Is there a patch for this issue that hasn't made it into mainline that I should test out? Is this an issue specific to KVM, or is it an openvswitch issue?
Than kyou, -Peter
