part is implemented by bug 994391 Lee, what other values you'd like to see? (In reply to Michal Skrivanek from comment #1) > part is implemented by bug 994391 > > Lee, what other values you'd like to see? Migration bandwidth is the most important but really any of the timeout variables would also be useful for larger guest migrations. list of current parameters affecting migration to consider to expose in UI, in order of importance: migration_max_bandwidth max_outgoing_migrations migration_downtime (configurable in 3.4) migration_downtime_delay migration_progress_timeout migration_downtime_steps migration_max_time_per_gib_mem migration_destination_timeout migration_listener_timeout *** Bug 1113945 has been marked as a duplicate of this bug. *** *** This bug has been marked as a duplicate of bug 1043809 *** Reopening, as this needs to address a per-VM setting, which will not be fully covered by vdsm.conf settings. Closing old bugs. If this issue is still relevant/important in current version, please re-open the bug. I think this is still relevant, especially since recently there are more and more cases when our defaults do not work well enough (e.g. 1Gb assumption/bandwidth limitation vs 10Gb link) we will expose meaningful parameters in bug 1252426 as well as improve the behavior *** This bug has been marked as a duplicate of bug 1252426 *** |
1. Proposed title of this feature request Allow migration configuration values to be set per VM from engine. 2. Who is the customer behind the request? N/A 3. What is the nature and description of the request? At present migration configuration variables are set host wide within vdsm.conf and apply to all guests being migrated from a given host. To allow better control of migrations VDSM should allow these to be set per VM and if possible this should be exposed by engine. 4. Why does the customer need this? (List the business requirements here) To allow better control of migrations on a per VM basis. 5. How would the customer like to achieve this? (List the functional requirements here) Extend VDSM to allow these variables to be set per VM. Extend engine to allow a user to adjust these values per VM. 6. For each functional requirement listed, specify how Red Hat and the customer can test to confirm the requirement is successfully implemented. Can a user set a given migration config variable from engine and have this used by VDSM? 7. Is there already an existing RFE upstream or in Red Hat Bugzilla? No. 8. Does the customer have any specific timeline dependencies and which release would they like to target (i.e. RHEL5, RHEL6)? RHEV 3.4 9. Is the sales team involved in this request and do they have any additional input? No 10. List any affected packages or components. vdsm and ovirt-engine-{api,backend}. 11. Would the customer be able to assist in testing this functionality if implemented? Yes GSS can help with testing this.
