veth interfaces aren't covered by persistent names anyway, as you
determine their name when you create them. What are you trying to do
exactly and how do you create the veth device pair?

Title:
  persistent network interface failed

Status in udev package in Ubuntu:
  Confirmed

Bug description:
  I've added net.ifnames=1 to GRUB_CMDLINE_LINUX_DEFAULT in
  /etc/default/grub, run sudo update-grub, removed /etc/udev/rules.d/70
  -persistent-net.rules but after reboot I still got eth0 interface
  which according to dmesg was renamed from veth9JEDKK (this ubunte-
  server 15.04 is installed in ovirt cluster).

  How can I avoid this renaming? What exactly causing this? Are there
  some leftovers in addition to 70-persistent-net.rules interfere?

  I don't want ubuntu's udev to be creative about interface naming,
  especially in potentially race-prone manner. What I want is the
  default upstream udev scheme described in
  http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/
  - the less ubuntu differs from other GNU/Linux, the easier it would be
  to maintain.
