# Limits VM memory to use no more than 16GB.

memory=16GB

# How much swap space to add to the WSL 2 VM.
# 0 for no swap file. A good starting point is equal to or double your memory setting.
# For a build like Cuttlefish, you might need a lot, e.g., 20GB or more.
swap=20GB

# This file will be created/managed by WSL. Ensure the path exists.
# Use double backslashes for Windows paths.

# How many processors to assign to the WSL 2 VM.
# Set this to a reasonable number of your CPU cores, e.g., half or two-thirds.
# For heavy builds, too many cores with insufficient RAM can also lead to OOM.
