I/O Terminal for VM on Imx8q-evk
by Chris Hofer 20 Apr '20

20 Apr '20

Hey, I'm continuously exploring for my thesis the Genode virtualization on the Imx8q-evk board. Currently the vmm_arm-runscript only allows to specify a static command, which is repeatedly sent to the VM after it booted. In order to run some benchmarks on the VM, I would like to interact with the VM by sending dynamically input. Is there a way to interactively send input to the TTY of the VM via e.g. the serial interface of the Imx8q-evk? If there is none, can you think of an easy way to build it? Best, Chris Hofer

Error while building boot image.
by Shlomo Pongratz 19 Apr '20

19 Apr '20

Hi, I'm trying to build sculpt according to document https://genode.org/documentation/sculpt-20-02.pdf. In section 5.2 Building the boot image stage 7 one finds: Create the Sculpt boot image (defined by the run script at repos/gems/run/sculpt.run) make -C build/x86_64 run/sculpt KERNEL=nova BOARD=pc The file repos/gems/run/sculpt.run exists. $ file repos/gems/run/sculpt.run repos/gems/run/sculpt.run: exported SGML document, ASCII text However there is an error: $ make -C build/x86_64 run/sculpt KERNEL=nova BOARD=pc make: Entering directory '/home/shlomo/development/all_git/genode.git/genode/build/x86_64' Error: No run script for sculpt make: *** [Makefile:323: run/sculpt] Error 255 make: Leaving directory '/home/shlomo/development/all_git/genode.git/genode/build/x86_64' Best regards, S.P.

Warning and Error while running on QEMU.
by Shlomo Pongratz 19 Apr '20

19 Apr '20

Hi, While running sculpt-20.02 on QEMU according to the instructions from https://genode.org/download/sculpt e.g. qemu-system-x86_64 -display sdl -cpu core2duo -machine q35 \ -m 1024 -drive format=raw,file=sculpt-20.02.img I've noticed the following warning and error: [init] Warning: runtime assigned RAM (32G) exceeds available RAM (659914929) [init] Error: RAM preservation exceeds available memory The maximum amount I can give the QEMU is 8G, is there anyway one can lower the memory requirement for a prebuild image? Best regards, S.P.

Shutdown
by Shlomo Pongratz 17 Apr '20

17 Apr '20

Hi, I'm running sculpt-20.02.img on QEMU and I wonder if the only way to shutdown sculpt is to kill QEMU? Is it the same for real HW (e.g. to push the reset button)? I'm sure it is somewhere in the documentation but I've failed to find it. Best regards, S.P.

ssh client error
by Star Lord 14 Apr '20

14 Apr '20

Hello friends! I thought it would be a good learning experience to attempt to setup the ssh client on Genode. I've decided not to worry about generating a pair of ssh keys and just test password authentication for now. I'm attempting to connect my laptop running Genode Sculpt 20.02 to a server running Ubuntu 19.10. I created a "host" file in one of my ahci filesystems' root directory and added the following: <host name="192.168.0.140" port="22" user="root" known="no"> >From the logs it seems like the computers recognize and acknowledge each other and, as expected, I receive an error message about a missing public key. Totally normal. But then I receive the following error messages: Error: password authentication denied Access denied for 'none'. Authentication that can continue: publickey,password Warning: rtc not configured, returning 0 It's a strange error message, because I explicitly allowed password authentication on my Ubuntu server. What do you think is causing the problem? I hope its okay that I ask simple questions here on the mailing list. The IRC channel isn't very active. Thanks, nooby

depot_query: segmentation in _query_blueprint?
by Roman Iten 14 Apr '20

14 Apr '20

Dear Genodians I'm lost and would appreciate some inspiration on how to further debug a problem in a scenario that is similar to `run/depot_query`. My scenario seems to work fine on x86_64 but on 32-bit ARM (base-linux) the `depot_query` component segfaults. Well, it doesn't always segfault but it seems to depend either on the `depot.tar` or the `deploy.config` or both. However, the `deploy.config` and `depot.tar` don't need to change much: only the depot user or the package version may vary. The segfault occurs in `Depot_query::Main::_query_blueprint(...)` when accessing the `node` parameter that has been instantiated by the class `File_content` when calling the lambda. I also need to mention that the segfault reproducibly occurs at the same "to be deployed" runtime (pkg/chroot) - at least for a given `depot.tar` / `deploy.config`. Other, much larger runtime files (~9k) have been processed successfully prior that in `pkg/chroot`. I'm aware that this is a rather vague description and therefore tried to provide a modified the `run/depot_query.run` so it uses my `deploy.config` and `depot.tar`. But no luck, I can't reproduce the problem this way... Has anyone an idea what could possibly lead to a "corrupt" instance of `Xml_node`? Or how to test hypotheses like a stack overflow, ...? Thanks, Roman

Running sculpt in qemu with networking
by Shlomo Pongratz 13 Apr '20

13 Apr '20

Hi, In the documentation there are instruction to run sculpt in qemu e.g. qemu-system-x86_64 -display sdl -cpu core2duo -machine q35 \ -m 1024 -drive format=raw,file=sculpt-20.02.img However there are no instruction for choosing the right network model for qemu. Is choosing e1000 is a good choice? What is the best practice? Best regards, S.P.

Adding a components script to Sculpt on Build?
by Lonnie Cumberland 13 Apr '20

13 Apr '20

Hi All, Really getting more into Genode Sculpt now but am still having the problem with the menu items being off the screen in nitpicker, I think that it is, when walking through the VirtualBox sequence from the "Sculpt Operating System 20.02" which references me to : " Use GNU/Linux inside a virtual machine on top of Sculpt There is a ready-to-use package for downloading Debian for the use inside a vir- tual machine along with the ability to use VirtualBox guest additions: https://genodians.org/jws/2019-07-08-download_debian-guest-additions-reload… For configuring and starting the virtual machine, you may find the following guide useful: https://genodians.org/m-stein/2019-03-07-vm-with-sculpt-ce-preview " I am particularly interested in starting up VirtualBox to see how that works but with the "off screen" problem persistent to select the options needed for "vm-with-sculpt-ce-preview" directions, I started to wonder if it might be possible to have some type of "script" that I could add in during the img/iso builds for Sculpt that would automatically select and add in all of the components needed so that I could just boot up this new modified img/iso and have the VirtualBox frontend GUI started up by default? Any ideas on how something like this could be done in Sculpt? On that note, does Genode have plans to update to the latest VirtualBox 6.1.4 (I think that it is now) in the near future? Cheers and have a great weekend, Lonnie
