kraft list -n not showing all the options

[dpadula]

Describe the bug I've cloned an installed kraft in the way showed here: https://github.com/unikraft/kraft with pip3

but when I run

kraft list -n

it is not showing all the options

To Reproduce In this video: https://ftp.osuosl.org/pub/fosdem/2020/K.4.601/uk_unicraft.mp4 more ARCHITECTURES and PLATFORMS are showed (I'm interested in linuxu)

In my case, I'm not have these options

Thanks in advance

Hi, kraft list -n pages all the result, so you may have to use the space bar to view more. What happens when you omit -n ?

[dpadula]

Hi, thank you very much for answer so quickly! I guess, the (real) problem is:

I guess I tried with an -n option.

You'll see, I've cloned from here and I've tried to reproduce the steps in the video (https://ftp.osuosl.org/pub/fosdem/2020/K.4.601/uk_unicraft.mp4) but the message when I try to follow the steps in "kraft configure -n" command, is: "unikraft Target architecture (x86) is currently not supported".

I promise to post properly this later because yesterday it was too late and maybe I was so tired to describe properly the error.

Thanks again Diego

[nderjung]

Ah i see,

This video is slightly out of date. I'm in the process of refactoring some of kraft which means there are some bits that are not upstream and so it may be best to work from this known working version of kraft and then i can give you concrete instructions:

pip3 install git+https://github.com/unikraft/kraft.git@99cdb90d76c73c74b3b66995ca64a8aad49e6b58
# (Optional) Set the location of your Unikraft source repositories (this defaults to ~/.unikraft):
# export UK_WORKDIR=~/.alt-unikraft-srcs
kraft list --update
kraft list
# now let's create an application
mkdir ~/my-unikraft-unikernel
cd ~/my-unikraft-unikernel
kraft init -m x86_64 -p kvm
kraft configure -k # this will open the make menuconfig, set everything you need including arch and plat
kraft build

Hope this helps :)

For now if you are relying on kraft.yaml file, you need to add any additional kconfig options you toggle in the menuconfig, since this is only written to .config (if this is discarded you will need to re-toggle all options, unless they are in kraft.yam)

Hey thanks Alexander! I promise I'll try this later. I have some questions now: 1) Can I ask you in the future how would I know from what patch "99cdb90d76c73c74b3b66995ca64a8aad49e6b58" clone kraft? 2) In my case, Debian 9 (stretch), do I must install some special package for menuconfig works?

Thanks again man! Cheers Diego

[nderjung]

So this version was just the one i have working. I'll be upstreaming more soon to master so we have something stable.

Also for the menuconfig to work (from the README.md):

apt-get install -y --no-install-recommends build-essential libncurses-dev libyaml-dev flex git wget socat bison unzip uuid-runtime

[dpadula]

Hey Alexander, I'm testing your instructions and so far so good until kraft list --update.

What am I doing wrong? Thanks one more time

Cheers Diego

I think the problem is I used pip3 (python 3.5). Now I installed and used python 3.7 and it seems to be working but the packages ad libs are the same.

What am I still doing wrong?

Thanks

[nderjung]

Are you, by chance, running a 32bit VM?

[dpadula]

Uhmmm, yes. I'm afraid so. Is that a problem ?

[nderjung]

This mode has not been properly tested with kraft yet. For now, it may be worth either switching to a 64-bit vm, or try using Unikraft in a more verbose manner.

[dpadula]

Oh I see, ok I'll try this and I'll let you know. It is very kind of you to have dedicated your time to me and this topic.

Thanks again Cheers

[nderjung]

No problem :)
