Live migration settings

[TwiX]

Hi,

I know it's possible to define specific interface (which is not the pve-cluster interface currently used) and bandwidth limit related to live migration. What are the related config files (with right syntax as well) ?
Do we have to restart something for these new settings to apply ?

Thanks in advanced !

see "man datacenter.cfg" for the network ("migration"), "man qm.conf" for the bandwith limit ("migrate_speed").

Thanks, but seems the 'man qm.conf' indicate that this migrate_speed setting must be settle to all kvm conf files right ?

correct. it also only applies to the memory part of live-migration, and not the disk part if you are using that.

Thanks, my goal is to use the ceph dedicated link which is 10G without taking all bandwidth. Ceph is currently using 300 Mbps
