Maybe not using the --nova-reboot until it is fixed could make the test
bed work for u-u and other packages.

'nova reboot' on arm64 is just 'nova reboot --hard' but slower
Status in nova package in Ubuntu:
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
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.
