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.
Thanks and have a wonderful day, Lonnie

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.

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.
I can run the "hello*.efi" versions with the "make qemu" but it seems that the framebuffer example cannot map a VGA screen and it might be something in the "dtc" which is the hardware settings for L4Re, if I read the documentation correctly, but am not sure on this.
Interestingly, is that if I take the "git" version of l4re and build things with "ham" then the framebuffer example will run under qemu with "make qemu" to execute it. the l4linux-mag will boot up the graphics but then it just shows a blank window and I suspect that the same errors (below) are happening with the errors " terminate called after throwing an instance of 'N2L413Runtime_errorE'"
For bot the git and non-git builds, the VM-multi and VM-multi-p2p examples l4re boots and I make it through SIGMA0, MOD, and NED while the Console Server also boots up, but then I get and errors in the VM's starting:
Created vcon channel: vm-1 [420010] cons> Created vcon channel: vm-2 [421010] cons> vm-1 | VMM[]: Created VCPU 0 @ 18000 vm-1 | VMM[]: >>> CAUTION: Support for AMD SVM is experimental, use at your own risk! <<< vm-2 | VMM[]: Created VCPU 0 @ 18000 vm-2 | VMM[]: >>> CAUTION: Support for AMD SVM is experimental, use at your own risk! <<< vm-2 | terminate called after throwing an instance of 'N2L413Runtime_errorE' vm-2 | what: Invalid request: SVM does not support next_rip save.

I think there is some VGA video problem somewhere that is preventing the VM's from completely booting up for some reason.
Best and have a great day, Lonnie

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.
