Sample Prerequisites: Sample Prerequisites:
The sample needs an existing VM. The sample needs an existing VM.
Note:
The sample adds new serial ports to the existing VM. If you re-run the sample
without cleaning up the previous created serial ports, the VM may be stuck at
power on stage as there will be multiple serial ports using the same output
file. In such case, you will see a question in vCenter UI asking if the file
should be Replaced or Appended.
To avoid this, make sure to pass -c to clean up the serial ports or manually
delete them after running the sample.
