[ovirt-users] Migration Failure Due to network

Nice, do you think I should dedicate a link only for migration, for safety ?

It's not highly used, it's yet on a 10/100 Mb switch...But it's just temporary. Anyway it's interesting because it simulates a highly use network, which can happen.

Thanks, but it doesn't seem to change anything : I added 
max_outgoing_migrations = 1
migration_max_bandwidth = 5
in /etc/vdsm/vdsm.conf
on my concerned host, but it still goes to 98% use of network and migration fail...I restart vdsmd.service but it doesn't seem to change anything. Any idea ?
