boot_keygroup_interval (duration string | ex: "1h5m2s") - Time to wait after sending a group of key pressses. The value of this
should be a duration. Examples are 5s and 1m30s which will cause
Packer to wait five seconds and one minute 30 seconds, respectively. If
this isn't specified, a sensible default value is picked depending on
the builder type.
-
boot_wait (duration string | ex: "1h5m2s") - The time to wait after booting the initial virtual machine before typing
the boot_command. The value of this should be a duration. Examples are
5s and 1m30s which will cause Packer to wait five seconds and one
minute 30 seconds, respectively. If this isn't specified, the default is
10s or 10 seconds.

boot_command ([]string) - This is an array of commands to type when the virtual machine is first
booted. The goal of these commands should be to type just enough to
initialize the operating system installer. Special keys can be typed as
well, and are covered in the section below on the boot command. If this
is not specified, it is assumed the installer will start itself.
