[ovirt-users] virtio-net name enp1s0 and not expected ens3
Hallo, looking for some hint where one can change the guest network name (not with udev
rules) but rather is there somewhere a code in ovirt/libvirt?
We have one from scratch installed ovirt engine (4.4.10.4-1.el8), where all guests have
enp*s* network name, all others engines (like 13 upgraded recently from 4.3.10 to 4.4.10)
have ens* network name.
In redhat KB https://access.redhat.com/solutions/3709641 is explained how is the naming of
virtio-net working
What is also different, there is missing ID_NET_NAME_SLOT in udevadm output:
~]$ udevadm info /sys/class/net/enp1s0/
P: /devices/pci0000:00/0000:00:02.0/0000:01:00.0/virtio0/net/enp1s0

Expected output of udeavm would be:
~]$ udevadm info /sys/class/net/ens3
P: /devices/pci0000:00/0000:00:03.0/virtio0/net/ens3
E: DEVPATH=/devices/pci0000:00/0000:00:03.0/virtio0/net/ens3
E: ID_BUS=pci

E: ID_MODEL_ID=0x1000
E: ID_NET_DRIVER=virtio_net
E: ID_NET_LINK_FILE=/usr/lib/systemd/network/99-default.link
E: ID_NET_NAME=ens3
E: ID_NET_NAME_MAC=enx001a4a070167
E: ID_NET_NAME_PATH=enp0s3
E: ID_NET_NAME_SLOT=ens3
E: ID_NET_NAMING_SCHEME=rhel-8.0
E: ID_OUI_FROM_DATABASE=Qumranet Inc.

Tested with different OSes like centos/debian, always the same output.
