What does 'reset' here mean? Is it a reboot or halt? If it's a halt, it involves
destroying a vm. If a host user just kills the qemu process, is it a reset involving
destroying a vm?

'reset' is either a complete reset ('system_reset' on the qemu monitor, cycles through the bios etc.) or just an INIT signal to one vcpu. Neither involves destroying a vm.

You aren't guaranteed a reboot notifier will be called.  On the other
hand, we need a kexec handler.
ordinary kexec calls all reboot notifiers. Only crash kexec doesn't call them.
I will implement a machine_ops.crash_shutdown callback.

Thanks.
