Building a Packer image (how’s that name for terrible Google juice):
==> qemu: Error launching VM: Qemu failed to start. Please run with logs to get more info.
So how do we run with logs? From Debugging Packer:
Packer has detailed logs which can be enabled by setting the PACKER_LOG environmental variable to any value
So in that case:
export PACKER_LOG=1
You can also define a logfile instead:
export PACKER_LOG_PATH="/var/log/packer"
