Re: Generating EFI files
Hi Adam, I was able to locate the QEMU settings needed and now can run all of the examples except the "L4Linux-Basic" one that reports and error of "Failed to map VGA area but CONFIG_VGA_CONSOLE=y." and stops at that point. I think that this is a similar message that I get when I try to run any of them on physical hardware Intel i5 NUC7, Intel i7 NUC13, and Dell XPS 8950 (11th Gen Intel(R) Core(TM) i7-11700 @ 2.50GHz 2.50 GHz) which reports that it cannot find a suitable video mode on all 3 systems. The good news here is that we have made some good progress with getting most of the examples to run under QEMU which is a great start, my friend.

Re: Generating EFI files
Hi Lonnie, please first ensure that on your NUC, KVM is properly used with QEMU. In the conf/Makeconf.boot file there is one commented out "QEMU_OPTIONS-amd64" line, please use this one instead of the one above. With -enable-kvm the right virtualization extensions are provided by QEMU such that VMs work and the error messages you're seeing shall go away.

Re: Generating EFI files
Hello Adam, Yea, I found the "make help" after sending off the messages and was able to take the latest "snapshot" (non-git) and build things, but have had only limited success in running them on my Intel NUC13 Ubuntu 23.10 (x64) system.

Re: Generating EFI files
Hi Lonnie, instead of "make qemu" one can also do "make efiimage" to generate an (U)EFI image. Please do "make help" to see the other options available.
