start pxe over ipv4

[jimmypierre.rouen.france]

Greetings,

I managed to create an Alpine Linux aarch64 on an Alpine Linux host x86_64
with the help of the folks at Alpine.

After setup-alpine, it boots OK.

I converted the img to qcow2 because my appliance only takes qcow2 of ISO.

No way of booting, it keeps saying Start PXE over ipv4. I have checked the
dhp log, it's got an ip address.

This is really the last furlong, please help if you can.

Cheers,
Jimmy

PS. Yesterday evening, Norbert suggested "Alpine EFI key" ? Could this be
the solution ?
