Tested patch and verified that it's working as expected. This bug was accidentally moved from POST to MODIFIED via an error in automation, please see mmccune with any questions I have verified that new live migration paramaters migration_speed and migration_downtime can be set for VirtualDomain in resource-agents-3.9.5-81.el7.x86_64 ---- See cluster setup at the bottom. Virtual machines live migration works correctly without these new params as well. migration_speed unset, takes about 10 seconds ...
