Note that if you leave the installnic/primarynic fields blank, it should
auto-switch between eth0 and eth2 if required.
If you want eth0 to specifically be one of the interfaces, you could omit one
of the drivers from the geninitrd phase. What adapters are controlling eth0
and eth2?

Subject: [External] [xcat-user] rhel7.6 diskless boot stalls
Hi all,
I created a diskless image for rhel7.6 using genimage (xCAT Version 2.13.7).
The dhcp/tftp boot process works fine, but
the execution of the initrd stalls after some time. Even the Dracut shell is
unusable.
I tried specify the bootif as described below in the tftp boot record, but it
doesn't help.
Performing a statefull install I noticed that the NIC HW instances are not
named (ethX) persistently during reboot. Aka
the primary NIC might be named eth0 or eth2, as this is not guaranteed by the
kernel.
* Does any know how to set the bootif in a deterministic way?
* Increase verbosity or chance to reach Dracut/emergeny shell to check
the system for error?
Many thanks for any help or advice.
Cheers,
-Frank
