Description Stephen Gordon 2012-08-29 10:28:17 EDT
Description of problem:

We reserve the port range 5634 - 6166 for Spice / VNC console connections, the port used for CIM (5989) - which we are also using - falls within this range.

This is the case in both Hypervisor hosts and RHEL hosts. For Hypervisor hosts the port ranges are set in the kickstart, for RHEL hosts they come from the rhevm-config options sent to vdsm-bootstrap.
Actual results:

VNC / Spice console port range overlaps default CIM port

Expected results:

We should not use, or potentially use, one port for more than one purpose.

Any thoughts on this?  

We could modify the cim server to run on a non-standard port or allow the port to be configurable, but I think this is just the first case of us colliding with the port range set aside for Spice/VNC.  Perhaps it's time to revisit this block of ports?
Comment 4 Andrew Cathrow 2013-07-11 17:18:55 EDT
This is already handled by the port detection mechanism
