1) Note directories in /sys/class/net are actually symlinks to /sys/devices, and that you are looking at qeth kernel devices 2) On an LPAR, it's a real connection to a real card and I can see 10000 connection 3) on z/KVM qeth is on virtio bus, thus it's all virtual. Only the host will know what the actual link speed is 4) similar on the z/VM only the host LPAR will know the real link speed and how it's shaped / limited by z/VM hypervisor for each guest
My expectation is that physical links are only validated on physical devices as connected to an LPAR, and not on virtualised devices as visible on KVM guest and z/VM guest. -- 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
