The original file looks like this: # PCI device 0x1af4:/sys/devices/pci0000:00/0000:00:04.0/virtio1 (virtio-pci) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR(address)=="00:01:a4:a2:b4:04", ATTR(dev_id)=="0x0", ATTR(type)=="1", KERNEL=="eth*", NAME="eth1" # PCI device 0x1af4:/sys/devices/pci0000:00/0000:00:03.0/virtio0 (virtio-pci) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR(address)=="00:01:a4:a2:b4:03", ATTR(dev_id)=="0x0", ATTR(type)=="1", KERNEL=="eth*", NAME="eth0" # PCI device 0x1af4:/sys/devices/pci0000:00/0000:00:05.0/virtio2 (virtio-pci) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR(address)=="00:01:a4:a2:b4:05", ATTR(dev_id)=="0x0", ATTR(type)=="1", KERNEL=="eth*", NAME="eth2" However, once the VM is either cloned or a new VM created from a template of this source VM, the file looks like this: # PCI device 0x1af4:/sys/devices/pci0000:00/0000:00:04.0/virtio1 (virtio-pci) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR(address)=="00:01:a4:a2:b4:04", ATTR(dev_id)=="0x0", ATTR(type)=="1", KERNEL=="eth*", NAME="eth1" # PCI device 0x1af4:/sys/devices/pci0000:00/0000:00:03.0/virtio0 (virtio-pci) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR(address)=="00:01:a4:a2:b4:03", ATTR(dev_id)=="0x0", ATTR(type)=="1", KERNEL=="eth*", NAME="eth0" # PCI device 0x1af4:/sys/devices/pci0000:00/0000:00:05.0/virtio2 (virtio-pci) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR(address)=="00:01:a4:a2:b4:05", ATTR(dev_id)=="0x0", ATTR(type)=="1", KERNEL=="eth*", NAME="eth2" # PCI device 0x1af4:/sys/devices/pci0000:00/0000:00:04.0/virtio1 (virtio-pci) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR(address)=="00:01:a4:a2:b4:10", ATTR(dev_id)=="0x0", ATTR(type)=="1", KERNEL=="eth*", NAME="eth3" # PCI device 0x1af4:/sys/devices/pci0000:00/0000:00:03.0/virtio1 (virtio-pci) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR(address)=="00:01:a4:a2:b4:0f", ATTR(dev_id)=="0x0", ATTR(type)=="1", KERNEL=="eth*", NAME="eth5" The 'correct' interfaces are still there, but out of sequence and there are two additional interfaces that do not belong there.
