[pve-devel] [PATCH V2] - fix setting migration parameters

[Alexandre DERUMIER]

>>Can we please try to find the bug first? 

Sure! but I can't reproduce it with 1sec.


But if I test with migrate_downtime:20, I got timeout on query-migrate. (but migration works fine)

Migration logs give me:
Dec 27 07:57:56 migrate_set_downtime: 20
Dec 27 07:58:16 migration speed: 400.00 MB/s - downtime 20423 ms
Dec 27 07:58:16 migration status: completed

Maybe are we doing too much qmp queries  during migrate ? (balloon stats, disk stats,....)

Can we please try to find the bug first? 

Nobody really want to set a default value for that - instead, migrations should simply work.
