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 /home/lonnie/l4re/build-amd64/assets /home/lonnie/l4re/build-amd64/bin/amd64_gen/l4f /home/lonnie/l4re/build-amd64/bin/amd64_gen/plain /home/lonnie/l4re/build-amd64/lib/amd64_gen/std/l4f /home/lonnie/l4re/build-amd64/lib/amd64_gen/std/plain /home/lonnie/l4re/build-fiasco-amd64 /home/lonnie/l4re/l4/conf/examples make[1]: *** [Makefile:693: qemu] Error 1 make[1]: Leaving directory '/home/lonnie/l4re/l4' 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' VMM[]: Created VCPU 0 @ 18000 VMM[]: >>> CAUTION: Support for AMD SVM is experimental, use at your own risk! <<< terminate called after throwing an instance of 'N2L413Runtime_errorE' what: Invalid request: SVM does not support next_rip save. Aborting!
===============================================
In trying to run the other VM-????? choices, I also get similar messages:
===============================================
vm-1 | VMM[]: Created VCPU 0 @ 18000 vm-1 | VMM[]: >>> CAUTION: Support for AMD SVM is experimental, use at your own risk! <<< vm-1 | terminate called after throwing an instance of 'N2L413Runtime_errorE' vm-2 | VMM[]: Created VCPU 0 @ 18000 vm-2 | VMM[]: >>> CAUTION: Support for AMD SVM is experimental, use at your own risk! <<< vm-3 | VMM[]: Created VCPU 0 @ 18000 vm-3 | 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-1 | what: Invalid request: SVM does not support next_rip save.

Aborting! vm-2 | vm-3 | what: Invalid request: SVM does not support next_rip save. Aborting! vm-3 |
=========================================================
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
