That is interesting indeed. The difference being on other systems the virtual functions are by default disabled which I guess is why no one is running into this problem with other hardware.
An example from a system with the ixgbe driver: # cat /sys/devices/pci0000\:00/0000\:00\:03.0/0000\:01\:00.1/sriov_totalvfs 63 # cat /sys/devices/pci0000\:00/0000\:00\:03.0/0000\:01\:00.1/sriov_numvfs 0 # ls -l /sys/devices/pci0000\:00/0000\:00\:03.0/0000\:01\:00.1/virtfn* ls: cannot access '/sys/devices/pci0000:00/0000:00:03.0/0000:01:00.1/virtfn*': No such file or directory While on a system with the Cavium Thunder X card: cat /sys/devices/pci0002\:00/0002\:00\:02.0/0002\:01\:00.0/sriov_totalvfs 128 # cat /sys/devices/pci0002\:00/0002\:00\:02.0/0002\:01\:00.0/sriov_numvfs 18 # ls -l /sys/devices/pci0002\:00/0002\:00\:02.0/0002\:01\:00.0/virtfn* lrwxrwxrwx 1 root root 0 Jun 29 08:24 /sys/devices/pci0002:00/0002:00:02.0/0002:01:00.0/virtfn0 -> ../0002:01:00.1 lrwxrwxrwx 1 root root 0 Jun 29 08:24 /sys/devices/pci0002:00/0002:00:02.0/0002:01:00.0/virtfn1 -> ../0002:01:00.2 lrwxrwxrwx 1 root root 0 Jun 29 08:24 /sys/devices/pci0002:00/0002:00:02.0/0002:01:00.0/virtfn10 -> ../0002:01:01.3 lrwxrwxrwx 1 root root 0 Jun 29 08:24 /sys/devices/pci0002:00/0002:00:02.0/0002:01:00.0/virtfn11 -> ../0002:01:01.4 lrwxrwxrwx 1 root root 0 Jun 29 08:24 /sys/devices/pci0002:00/0002:00:02.0/0002:01:00.0/virtfn12 -> ../0002:01:01.5 lrwxrwxrwx 1 root root 0 Jun 29 08:24 /sys/devices/pci0002:00/0002:00:02.0/0002:01:00.0/virtfn13 -> ../0002:01:01.6 lrwxrwxrwx 1 root root 0 Jun 29 08:24 /sys/devices/pci0002:00/0002:00:02.0/0002:01:00.0/virtfn14 -> ../0002:01:01.7 lrwxrwxrwx 1 root root 0 Jun 29 08:24 /sys/devices/pci0002:00/0002:00:02.0/0002:01:00.0/virtfn15 -> ../0002:01:02.0 lrwxrwxrwx 1 root root 0 Jun 29 08:24 /sys/devices/pci0002:00/0002:00:02.0/0002:01:00.0/virtfn16 -> ../0002:01:02.1 lrwxrwxrwx 1 root root 0 Jun 29 08:24 /sys/devices/pci0002:00/0002:00:02.0/0002:01:00.0/virtfn17 -> ../0002:01:02.2 lrwxrwxrwx 1 root root 0 Jun 29 08:24 /sys/devices/pci0002:00/0002:00:02.0/0002:01:00.0/virtfn2 -> ../0002:01:00.3 lrwxrwxrwx 1 root root 0 Jun 29 08:24 /sys/devices/pci0002:00/0002:00:02.0/0002:01:00.0/virtfn3 -> ../0002:01:00.4 lrwxrwxrwx 1 root root 0 Jun 29 08:24 /sys/devices/pci0002:00/0002:00:02.0/0002:01:00.0/virtfn4 -> ../0002:01:00.5 lrwxrwxrwx 1 root root 0 Jun 29 08:24 /sys/devices/pci0002:00/0002:00:02.0/0002:01:00.0/virtfn5 -> ../0002:01:00.6 lrwxrwxrwx 1 root root 0 Jun 29 08:24 /sys/devices/pci0002:00/0002:00:02.0/0002:01:00.0/virtfn6 -> ../0002:01:00.7 lrwxrwxrwx 1 root root 0 Jun 29 08:24 /sys/devices/pci0002:00/0002:00:02.0/0002:01:00.0/virtfn7 -> ../0002:01:01.0 lrwxrwxrwx 1 root root 0 Jun 29 08:24 /sys/devices/pci0002:00/0002:00:02.0/0002:01:00.0/virtfn8 -> ../0002:01:01.1 lrwxrwxrwx 1 root root 0 Jun 29 08:24 /sys/devices/pci0002:00/0002:00:02.0/0002:01:00.0/virtfn9 -> ../0002:01:01.2 # cat /sys/devices/pci0002\:00/0002\:00\:02.0/0002\:01\:00.0/virtfn0/net/enP2p1s0f1/phys_port_id cat: '/sys/devices/pci0002:00/0002:00:02.0/0002:01:00.0/virtfn0/net/enP2p1s0f1/phys_port_id': Operation not supported And this is on by default, without a operator having enabled the virtual functions. libvirt finds the virtual functions this way: https://github.com/libvirt/libvirt/blob/0b86e23d25696c08234d4b73c90cef9515befe84/src/util/virpci.c#L2688 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1771662 Title: [bionic] libvirtError: Node device not found: no node device with matching name To manage notifications about this bug go to: https://bugs.launchpad.net/charm-nova-compute/+bug/1771662/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
