CI: FreeBSD fix

[alonfaraj]

• Try to resolve FreeBSD CI hangs CI: add FreeBSD & simplify CUDA windows #3053 (comment).
  As mentioned here Very frequent freezing of FreeBSD VM during teardown cross-platform-actions/action#61, seems like qemu + macOS should function better, I think it worth a try before setting a timeout.
  @Green-Sky what do you think?

- Update Ubuntu make job to use latest instead of Ubuntu 20.04 and gcc-8

Update Ubuntu make job to use latest instead of Ubuntu 20.04 and gcc-8

this is actually intentional, to test the older gcc 😄

Oops 😅
Fixed.

Do you have a test run somewhere?

[Green-Sky]

lets see if this is more reliable

Error: Waiting for VM to become ready timed out after 120 seconds

[Green-Sky]

well, at least it fails fast now (instead of >2h doing nothing)

@Green-Sky
I was looking around for other solutions because seems like this action doesn't function so well.
I have found https://github.com/vmactions/freebsd-vm which seems to be more stable and didn't notice any reported issues.
I have tested it, ran 10 times in a raw, everything works as expected and looks good.
No warnings etc. like we have now.
The test are here.
You can see the 10 attempts on the right upper corner.
Let me know if you think it worth a try before we give up 😁

[Green-Sky]

hmm I took a look around, and it seems that this runner is still using macos as the "host".
Although it says that you can run qemu on macos, it says:

The FreeBSD and OpenBSD VMs run on the xhyve hypervisor (on a macOS host), while the other platforms run on the QEMU hypervisor (on a Linux host).

... maybe we should just try a linux host first, just to check.

also, seems like https://github.com/vmactions/freebsd-vm installs full on virtualbox. I would prefer qemu. 😄

It's working now. What changed? https://github.com/ggerganov/llama.cpp/actions/runs/6266338778/job/17017092230?pr=2268

[alonfaraj]

@cebtenzzre nothing 😅
It tends to work most of the times by looking at the actions history.
Seems to be generally unstable.

[Green-Sky]

yea it just flakes sometimes, just rerun it for now.

The difference between a successful run and a failed run seems to be this error:
