Introduction to UEFI HTTP(s) Boot with QEMU/OVMF

People reading it largely saw HTTP boot itself as the practical win. Running an HTTP server is easier than maintaining TFTP, and current server hardware usually supports UEFI HTTP boot in some form. Several comments pointed out that this is already viable on real metal, either directly through firmware, through DHCP-delivered HTTP boot options, or by falling back to iPXE when vendor firmware gets in the way. Where the conversation sharpened was around what HTTPS actually buys you. Secure Boot already checks signatures on the bootloader and kernel, so transport encryption does not replace signed payload verification. The useful case for HTTPS is not basic integrity of the boot image. It is request privacy, client or server authentication, and some protection against replaying older signed but vulnerable software if you are not otherwise enforcing version policy. Even then, many commenters saw firmware TLS stacks as exactly the wrong place to add more complexity. The strongest practical warning was about implementation quality. UEFI HTTP clients are inconsistent, sometimes expect odd details like filename extensions, and often fail with useless error messages. Debugging DHCP, IPv4 versus IPv6 behavior, relays, and boot file handling is painful enough that the advice was to copy the post’s approach and get the whole path working in OVMF first, where you can sniff packets and iterate quickly, before trying vendor firmware on physical servers.
