Doc Text:	Previously, libvirtd live-migration used ports 49152 to 49215, as specified in the qemu.conf file. On Linux, this range is a subset of the ephemeral port range 32768 to 61000. Any port in the ephemeral range can also be consumed by any other service. As a result, live-migration failed with the error: Live Migration failure: internal error: Unable to find an unused port in range 'migration' (49152-49215). With this update, the new libvirtd live-migration range of 61152-61215 is not in the ephemeral range and the related failures no longer occur. This completes the port change work started in BZ1573796.	Story Points:	---

Comment 14 Bryan J. Smith 2018-11-05 23:47:34 UTC

It actually looks like RHBA-2018:2670 causes an issue on *new* compute nodes deployed without re-deployment of *all* compute nodes that existed prior to RHBA-2018:2670, even if those compute nodes were updated and rebooted.
