Hello All,
I am on an Intel NUC 13 NHNE (x64) running Ubuntu 23.10 and am working
my way through the basic Qemu Demos after following the build instructions
https://github.com/kernkonzept/manifest/wiki/BUILDING
From there I am in the "~/l4re/build-amd64$" and have added
"/l4re/l4/conf/examples" to the "l4/conf/Makeconf.boot"
Now I do a "make qemu" and get the list:
===============================================
│
│ │ 0 hello
│ │ 1 hello-cfg
│ │ 2 hello-2
│ │ 3 hello-shared
│ │ 4 framebuffer-example
│ │ 5 L4Linux-basic
│ │ 6 L4Linux-mag
│ │ 7 VM-basic
│ │ 8 VM-multi
│ │ 9 VM-multi-p2p
│ │ 10 VM-basic-pci
===============================================
For which I have been able to run items 0 - 3, but when I run (4)
"framebuffer-example", I get an error about a missing "x86-lagacy.devs"
file and I cannot find it anywhere in the sources or builds.
===============================================
Could not find
'x86-legacy.devs'
within paths

make: *** [Makefile:6: do-all-make-goals] Error 2
===============================================
I then restarted "make qemu" and tried (7) VM-basic, but it seems to
abort with the messages:
===============================================
MOE: Starting: rom/ned rom/vm-basic.cfg
MOE: loading 'rom/ned'
Ned says: Hi World!
Ned: loading file: 'rom/vm-basic.cfg'

risk! <<<

what: Invalid request: SVM does not support next_rip save. Aborting!
===============================================
In trying to run the other VM-????? choices, I also get similar messages:
===============================================

=========================================================
Has anyone been able to get all of these to run?
I am still exploring but would like to get the be able to compile and
run the VM-multi examples on the x64 hardware like in the video.

Any thoughts on how to test out some of these?
Best and have a great weekend,
Lonnie
