@amonsifr seems like your system doesn't support KVM. I got this from the log message Could not access KVM kernel module: No such file or directory
. Try loading the KVM kernel module.

from kata-containers.
you may want to check the kata-runtime kata-check
command, it will try to evaluate if you system could use KVM to build a VM. ;)
BTW, I, and my colleague, @jongwu, is also trying to run kata containers in Respberry 4, and the official kernel will be for 32bit. Is this your customized 64bit kernel? Happy to collaborate~~~~

good job @amonsifr . I have a pi4 but I find there is no official or third party linux distribution for arm64. so how do you install this ubuntu 19.04 on pi4. I can build a environment like you and test kata.
as far as your issue, I think you can run a vm using qemu first to test if the qemu works, then you can run kata without docker, just using "kata-runtime run "container-name", you need rootfs and config file at side.
also you can grab the command line of qemu when run kata and run these command line by hand to trace.

sudo kata-runtime kata-check
WARN[0000] VM memory (512MB) smaller than image "/usr/share/kata-containers/kata-containers-2019-08-28-14:34:51.381609631+0000-64caa3f" size (1024MB)
System is capable of running Kata Containers
System can currently create Kata Containers
for the 64 bit kernel I have started with the following page:
https://blog.cloudkernels.net/posts/rpi4-64bit-image/
from kata-containers.
You may prefer the initrd
as your guest rootfs. it will be much smaller than image.
And you can decrease the VM memory in configuration.toml
, the default value will be 2GB.
from kata-containers.
I have used the initrd as my guest rootfs and this is better I haven't anymore the warning about the problem of VM memory size.
I have tried :
sudo kata-runtime --log /tmp/kata4.log run hardcore_noyce
fail to launch qemu: exit status 1, error messages from qemu log:
in the log file I have found:
error="open /run/vc/sbs/hardcore_noyce/devices.json: no such file or directory
Do you know what I am doing wrong ?
I haven't found any devices.json file on the raspberry...

Hi @amonsifr - please could you re-run the sudo kata-collect-data.sh
and paste the output in a comment here?

Hello,
If you want to build the same environment as mine you can use the following set of scripts :

thanks @amonsifr , I will try this.
from kata-containers.
@amonsifr sorry to let wait so long.
I have tried kata on my respberry pi4. I can run kata now. I think your problem is lack of ram in your pi4.
I have 4G ram but you just 2G.
when I set my pi4 to 2G, I can't run kata too like you.
from kata-containers.
good news @amonsifr
set image as your rootfs and set the default memory to 512M then kata will boot up.
I set my pi to 2G and do as above. it works. you can try it.
