Server IP address is 192.168.70.9
NBP filename is undionly.kpxe
Downloading NBP file …NBP thread download successfully
OMG, this is why I don’t answer questions late at night. I totally missed what was in front of me. NBP implies uefi firmware, but you are sending undionly,kpxe which is for a bios firmware computer. The uefi firmware will reject that file.
Update dhcp option 67 to ipxe.efi and the vm should boot.
