Title: 'nova reboot' on arm64 is just 'nova reboot --hard' but slower Status in OpenStack Compute (nova): Confirmed Status in nova package in Ubuntu: Confirmed Status in systemd package in Ubuntu: New Bug description: Within Canonical's multi-architecture compute cloud, I observed that arm64 instances were taking an unreasonable amount of time to return from a 'nova reboot' (2 minutes +, vs. ~16s for POWER in the same cloud region). Digging into this, I find that a nova soft reboot request is doing nothing at all on arm64 (no events visible within the qemu guest, and no reboot is triggered within the guest), and then after some sort of timeout (~2m), 'nova reboot' falls back to a hard reset of the guest. Since this is entirely predictable on the arm64 platform (because there's no implementation of ACPI plumbed through), 'nova reboot' on arm64 should just skip straight to the hard reboot and save everyone some clock time.
