contest: stop the VM after a crash?

[matttbe]

When quickly looking at the recent modifications, I noticed 290b9b0 reduced the timeout in case of crash.

To deal with that, in our CI scripts for MPTCP, we add CONFIG_PANIC_TIMEOUT=-1 in the kernel config. To avoid the VM to reboot and mess-up with automation, we launch virtme with --qemu-opts -no-reboot, but I don't know what's the equivalent with virtme-ng.

While at it, we also enabled CONFIG_BOOTPARAM_SOFTLOCKUP_PANIC and CONFIG_BOOTPARAM_HUNG_TASK_PANIC.

Maybe it would be easier to maintain a ci.config file in the selftests? Or always set that in lib/vm.py?

Interesting. I was trying to stay away from CONFIG_PANIC_TIMEOUT=-1 because when I do testing on real HW before PRs I see unrelated stack traces very often :( Maybe QEMU is much better tested. Let's keep this as an option if things start acting up again!
