Description Lee Yarwood 2016-02-24 11:46:17 UTC 
Description of problem:

Serial port collisions can occur when live migrating instances.

The live migration of instances with serial ports attached is supported with Liberty. BZ#1310140 also enables these live migrations for RHEL OSP 7.0.z.

Version-Release number of selected component (if applicable):
12.0.1
2015.1.3

How reproducible:
Always.

Steps to Reproduce:
1. Live migrate an instance to a destination host where an instance is already using a given serial console port.

Actual results:
Live migration fails as these ports collide on the destination host.

Expected results:
A new serial console port is selected on the destination and used by the migrating instance.
