qemu error running unikernel .elf

[zephryn]

this was done using the precompiled v0.4.1 binary provided in the releases section (go version -m indicates it was built with 1.16.6).

running egg build -o kernel.elf and then egg run kernel.elf or running egg test in the go project's directory returns the following error from qemu:
qemu-system-x86_64: multiboot knows VBE. we don't

Hi, zephryn. This is a warning from qemu, not an error. The qemu started by egg test does not support the VBE graphical interface, and can only print text content to the terminal.

This was also confusing for me when starting to use eggos. The solution was to use egg pack instead of egg build to produce an ISO instead of an ELF file of the kernel. Then use egg run foo.iso. Perhaps this could be documented somewhere, or the warning could be extended (I know the warning is from Qemu and not eggos, so perhaps not easy to extend)?
