vm shutdown {guest} &
(sleep N && vm poweroff {guest}) &
A bit hackish, but that should work, if the guest has
shutdown by the time you get to the poweroff an error
might occur. This spawns a few processes, but is
non blocking and highly parallel.
One thing I noted, you said rc.d/vm, so I am assuming your actually
using the vm-bhyve port, in which case it has a sequential shutdown
with time delays between each guest. vm_delay specifically, and it
shuts vm's down in reverse order of the startup.
That is more likely your problem in that your sending these acpi
shutdown requests one at a time, and they should be broadcast in
the "power going out" case.
It may be possile to adjust vm_delay to 0 and have that be better,
though I have not locked at the code. You may also wish to discuss
the issue with the vm-bhyve maintainer and maybe a "lights out"
procedure needs to be added.
