I would guess it would not work on a DVD?). I have downloaded it yesterday, and tried it on 3 computers (2 almost the same: Dell Optiplex 745, not sure the other is a 745 too). One of the two is my own computer, and I have try many BIOS config, but it does always do the same: show the Logo, screen become black for about 7 secs... then it reboots and loop. Hi Paul, Welcome back ;-) I noticed the same boot loop on a Dell Optiplex 380. This one is so old it has a serial and parallel port. The serial port showed me some boot lines and if I remember correctly it was something about missing video card before the reboot. If someone wants, I can capture that serial log and hardware specs. I'm not sure if the GMA 4500 video chip is supported by Genode, if you have an old VESA video card lying around, you might have some more luck on the Dell. I ran Sculpt on a 6 year old Sandy Bridge Pentium (G620) with built-in video chip, that runs great, after some trouble with network and usb. Genode likes my Intel gbit Nic better than the RTL 8111/8169. I got some spurios hangs on the latter. It also booted on my AMD Ryzen 5 system but it did not detect SATA drives. Nor did virtualisation work. Both Vbox and Seoul hang. Better than I expected but not usable yet. Hope this encourages you to keep going on with Genode :-) Cheers, Guido. ___ Genode users mailing list users@lists.genode.org https://lists.genode.org/listinfo/users

So it still runs but doesn't produce any log output. That explains why I thought it didn't work at all (I tried run/log). That solves the issue for me, thanks.

Testing sculpt on different hypervisor
Hello Andreas, welcome to Genode's mailing list! On 04.07.2018 20:04, Johannes Kliemann wrote: > Does it work with Sculpt?

I routinely test-drive sculpt in Qemu running in my Linux VM on top of Sculpt using the gems/run/sculpt_test.run script. So Sculpt should in principle come up in KVM on a native Linux system. For reference, in my test scenario the Qemu command line looks as follows: qemu-system-x86_64 \ -no-kvm \ -display sdl \ -cpu core2duo \ -m 768 -net nic,model=e1000 -net user \ -serial mon:stdio \ -device ahci,id=ahci \ -drive id=hdd,file=bin/sculpt-ahci.raw,format=raw,if=none \ -device ide-hd,drive=hdd,bus=ahci.1 \ -drive format=raw,file=var/run/sculpt.img \ -machine q35 > Does it work in form of being usable? I don't think so but ymmv. I agree. In Qemu without KVM, it is bearable for testing but not for using. Regarding nested virtualization in Qemu/KVM, you'd need to enable at least the AMD Phenom CPU model (-cpu phenom) in Qemu. Our automated tests of the Seoul VMM (as used in Sculpt's 'seoul-vmm-browser package') work that way. But I have not used this configuration interactively. Cheers Norman -- Dr.-Ing.

Indeed, core maps that capability to each component, but it is not critical. The capability is only used for testing purposes. Normally it is not used. Thereby the warning can be ignored. If I uncomment the mapping the warning vanishes. Moreover, core sets names to ease debugging for all threads in the kernel debugger. I've prepared an interims commit for you to use Genode/Fiasco.OC without kernel debugger: https://github.com/skalk/genode/commit/e38ebf4a2de0029f46afdc5b6b6f3c480388fcf2 Anyway, you won't see any messages on serial line from Genode, because it uses the kernel debugger's outstring method.

Fullscreen VM in sculpt

In config/input_filter, 'LEFTMETA' (windows key) is mapped to 'SCREEN' by default. In contrast to your observation, it is not disabled. Do you happen to use a stale input_filter configuration? Does [LEFTMETA]+[TAB] works for cycling through multiple windows? If yes, then the input filter and window layouter are configured correctly. This should be the case by default. The VM's response to maximize events (as triggered by [LEFTMETA]+[ENTER] or by the maximize button at the top-left window corner) is a bit of a hit-or-miss, unfortunately. The screen-size change is handled the VBox guest additions. So it does only work when those are installed and running. Even if so, it sometimes takes quite a long time for the screen change to take effect. The delay needs further investigation. But apart from this, it should work in principle.
