For LPAR -> it's a valid test to verity max speed and actual speeds For z/VM -> the cards are virtualised on the host, thus any test of max & actual speeds is bogus For z/KVM -> the cards are virtualised on the host, thus any test of max & actual speeds is bogus Comparing z/VM and z/KVM with other architectures is also bogus, as completely different kernel drivers are used to implement the cards (qeth driver on a CCW bus and CCW-virtio bus, CCW buses are entirely s390x specific)
At best this is a wishlist bug report against upstream z/VM & upstream qemu to expose something more realistic in the guest, which kernel then can pick up and display. What kernel is showing to you, is as much as it knows, and there is no bug there as far as I can tell. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1572347 Title: problems with network speed reporting in sysfs on s390 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1572347/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
