Understanding live migration "migration_max_bandwidth" and "max_outgoing_migrations" parameters in vdsm.conf
Issue
-
Is there any theory on how to configure the
migration_max_bandwidthandmax_outgoing_migrationsparameters in/etc/vdsm/vdsm.conf? -
We are using RHEV environment and now considering to optimize performance of migrations. We found the following parameters in
/usr/share/doc/vdsm*/vdsm.conf.sample. How do those parameters work ? What should I be careful with when tuning these parameters ?
# migration_max_bandwidth = <X>
<..snip..>
# max_outgoing_migrations = <Z>
Note: the file vdsm.conf.sample is available only on RHEL base hypervisor. Not on RHEV-H environment. Also the values and comments depends on versions of vdsm package.
