examples/Debian OS provisioning not working- kexec?

[jimmyat]

When using the example listed at https://docs.tinkerbell.org/deploying-operating-systems/examples-debian/ I can't seem to get kexec working- I get a "function not implemented" error. It's unclear if this is due to a lack of kexec support in OSIE (should I be using OSIE?) or somewhere else.

Expected Behaviour

Using the example at the link above should execute kexec to switch to the new debian kernel after streaming the image.

Current Behaviour

The kexec action goes to STATE_FAILED with the error: function not implemented.

Possible Solution

Unsure if this down to OSIE or the debian image; suspect the former since afaik Debian Buster has exec support baked-in by default. Should I be using OSIE, or do the examples require something different (hook?)

Steps to Reproduce (for bugs)

Create the template using the first example in https://docs.tinkerbell.org/deploying-operating-systems/examples-debian/
Create a workflow and boot the VM, observe the results.

Context

I am unable to use the kexec action and the workflow does not complete.

Your Environment

MacOS, using the vagrant method.

I recently came across this issue. Switching to hook, I was able to use the kexec image.

Although switching to hook is a bit easier said than done as it requires you to build it through LinuxKit

Had the same issue using osie-v0-n=404,c=c35a5f8,b=master, have you tried newer builds of osie? According to the action hub page for kexec this happens because the kernel that "tinkie"(I'm guessing it means osie) is running doesn't support kexec.

I'm having the same issue with osie-v0-n=404,c=c35a5f8,b=master.
@Belchy06: with which hook's git SHA revision were you able to make it work? Thanks

[jacobweinstock]

With #90 landing, Hook is now the default. Would you two @jimmyat, @damdo mind trying with the new sandbox to validate?

The hook download link being used can be found here.

@jimmyat did you get a chance to test with Hook to confirm that it fixed kexec for you?

Closing due to inactivity and under the assumption that hook does not have this issue.
