# BASIC CONFIGURATION (FEDORA 37)
# ===================================================================== #
# Default values in this YAML file are specified by `null` instead of Lima's "builtin default" values,
# so they can be overridden by the $LIMA_HOME/_config/default.yaml mechanism documented at the end of this file.
# VM type: "qemu" or "vz" (on macOS 13 and later).
# The vmType can be specified only on creating the instance.
# The vmType of existing instances cannot be changed.
