Also affected by this bug with Ubuntu 12.04LTS kvm. A tracepath in a VM with virtio network card ends with: Resume: pmtu 65535. While with pcnet or rtl8139 it properly ends with: Resume: pmtu 1500
This is pretty blocking given some servers are failing to communicate because of the wrong MTU (I've the case with a mail server). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1297487 Title: MTU not honored in virtio vnet To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/1297487/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
