[Bug 1437024] Re: Failure to PXE-boot from secondary NIC

[Jeff Lane]

@cyphermox, any update on this?  I believe we have run into this in the
field as well with a customer lab doing certification testing for
16.04.3.

Title:
  Failure to PXE-boot from secondary NIC

Status in MAAS:
  Invalid
Status in grub2 package in Ubuntu:
  New

Bug description:
  On a Lenovo x3550 M5 with the standard 4-port 1Gbps NICs and a
  secondary (plug-in) 2-port 10Gbps NIC, an attempt to PXE-boot from the
  secondary NIC in UEFI mode causes a boot failure with a "grub>" prompt
  on the display.

  This server arrived for certification with both NICs enabled. I
  suspect, but am not positive, that which NIC is chosen for booting is
  semi-random, although it favors the secondary NIC. The system PXE-
  boots fine from the built-in ports (generally the first one, eth0),
  and when booting from eth0 is forced via the UEFI boot menu,
  enlistment, commissioning, deployment, and post-deployment booting all
  work fine.

  When the system PXE-boots from the secondary NIC, though, the normal
  UEFI PXE-boot messages appear on the screen, followed by the
  aforementioned "grub>" prompt. This obviously prevents normal
  operation of the server with MAAS. It appears from the logs (attached)
  that when using the failed NIC, the MAAS server doesn't receive
  follow-on requests from GRUB.

  As a workaround, the secondary NICs can be configured to not support
  PXE-booting in the firmware setup utility; this enables normal
  deployment via MAAS.
