[Minios-devel] Booting mini-os from USB as a standalone kernel

["Kramer, Sean D." <skramer@xxxxxxxxxx>]

I am looking to boot Xen as a kernel image that is not attached to Linux or a filesystem. It does not matter if the image fails to completely boot.

Mini-OS appears to be a valid option, as it only provides a small kernel image of Xen. When building mini-os, the resulting binary is an ELF file, and that cannot be booted as it does not contain a header file or multiboot information, unlike the fully-fledged Xen file.

For this to work, must I attach a custom bootloader file to mini-os and then burn it to a USB? When previously working with the Xen image, I could not get past the initial switch to long mode before crashing.

Thank you.
