A request to create a VM: which image to boot, the instance size, the guest architecture, and optional kernel boot args.
type defaults to :base. arch defaults to nil, meaning "resolve to the
scheduling node's architecture at create time" (Hyper.create_vm/1 fills it in
via Sys.Arch.current/0). boot_args defaults to nil, meaning the standard
serial-console cmdline (Hyper.Node.FireVMM.BootSpec's default).
