Can CRIU use arm based runners from Actuated?

[adrianreber]

Hello @alexellis, you mentioned in a runc and CRI-O ticket that Actuated now has 6.x based kernels for their aarch64 runners.

Would it be possible for CRIU to also use those runners for CI testing?

You can see how runc enabled this: opencontainers/runc#4142

Hi @adrianreber @kolyshkin how many jobs do you think you'd be generating?

[adrianreber]

Looking at the history of the last 6 months there were around 50 pull requests. A pull request takes a couple of attempts before it is merged, but I would say an average of 6 CI runs each for 50 pull requests. A common test setup we have is to built and test CRIU once with GCC and once with LLVM. That would mean 50 pull requests * running around 6 times * 2 CI setups. So maybe something like 600 runs in 6 months on average. 100 per month. The free GitHub Actions runners need around 25 minutes for building and running all tests in the last few months.

@alexellis Is that helpful?

Let's get your details if that's OK? https://docs.google.com/forms/d/e/1FAIpQLScA12IGyVFrZtSAp2Oj24OdaSMloqARSwoxx3AZbQbs0wpGww/viewform?usp=send_form

Hi @kolyshkin and @adrianreber

Quick question - now that GitHub offers free Arm runners for OSS. We can see that you had some teething issues with them back in April, but are you now in a position to switch over to their runners?

Outside of our own future plans like offering a Rocky9 image, is there any reason for you to retain access to actuated?

Regards,

Alex

@alexellis yes, let's try to move to GHA provided ubuntu-24.04-arm. Trying with runc first (opencontainers/runc#4844), hitting a few snags along the way, but we'll get there.

@alexellis CRIU is using the GitHub Actions arm64 runners in parallel to the actuated runners for some time now. As @kolyshkin mentioned three tests are not working on the GitHub runners for some weeks now. Not sure why.
