Hi Dmitry,
I tried taking TCPDUMP while the Baremetal Node was booting up and looked
for tftp protocols and found there was some "*File Not Found" *traces for
bootx64.efi
[image: image.png]
Then, I found a related post on openstack Discuss which suggested to enable
IPXE
http://lists.openstack.org/pipermail/openstack-discuss/2019-October/010329.html
After re-deploying the setup with IPXE enabled, i found similar traces now
for *ipxe.efi file*
[image: image.png]
Can you please now suggest what possibly could be a miss in configuration
and steps to resolve it.
For your reference, I am attaching the complete tcpdump logs of both the
Scenarios
Looking forward to hearing from you.
Regards
Anirudh Gupta
