# Convenience script to run a qemu monitor into a particular VM
|
|
#
|
|
# This script takes arguments from environment variables -- all optional. They are:
|
|
#
|
|
# * VM_NAME - the vm.neon.tech/name of the VM. Optional if there is only one VM, otherwise must
|
|
# be provided.
|
|
# * RAW - if set to 1, socat instead of qmp-shell will be used to connect to the monitor.
