# Starts an ephemeral virtual machine in qemu, injecting configuration via

# cloud-init. Stopping this script stops the VM and discards all data.

# IMAGE -- An os image that can be booted by qemu and has cloud-init
|
|
# installed and enabled. No changes are made to this file.
|

|
|
# USERDATA -- A cloud-init user-data config file, or a directory of
|
|
# configuration as accepted by the `gen-user-data` tool.
|
|
#
|
|
# In addition, if the QEMU_EXTRA_ARGS environment variable is defined, it adds
|
|
# its content as additional arguments to qemu.
