# File: check-qemu-install
# Purpose:
#  This script installs a system on a emulated qemu host to verify
#  that the iso produced is installable and boots.
#  after the iso is booted from disk it also tries to execute the
#  vyos-smoketest script to verify checks there.
#
#  For now it will not fail on failed smoketest but will fail on
#  install and boot errors.
#  Arguments:
#    iso            iso image to install
#    [disk]         disk filename to use, if none is provided it
#                   is autogenerated
#    [--keep]       Keep the disk image after completion
#    [--logfile]    name of logfile to save, defaulting to stdout
#    [--silent]     only print on errors
#    [--debug]      print all communication with the device
